 Excellent - I'm glad you decided to continue.

Yes, I am continuing for the time being, finances etc permitting.

 From what I've seen and heard of the UK supplier 3 (the only 3G only network
 here AFAIK), it's reasonable to think 2G is going to still be around for a
 good long while, at least in some parts of the world.

The 2G service provided by Operator 310260 in my part of the world is
still working OK for now too.

It is really a race: we need to get our Free Dumb Phone working in an
end-user-usable state a year or two before 2G services shut down.  If
Operator 310260 starts shutting down its 2G services when we have a
few hundred (or maybe even a thousand) users with our totally free
phones, they might think twice about losing that many customers, and
could perhaps be convinced to keep a tiny sliver of 2G capacity around
for this segment of their customer base - and if not, if they do shut
their 2G down despite all of our pleas, if we have a thousand users in
our camp, we may be able to pull enough of our own resources together
to set up our own operational 2G network to replace the ones taken
away from us by the mega-carriers.

 In the hope of the project advancing to this stage, I'm interested in picking
 up a dumbphone before I return to SA. Is the C139 the best bet?

It appears to be, as of this moment, subject to change as the project

 I notice that osmocomBB says the C140 is virtually identical to this model.

Yes, C139 and C140 appear to be exactly the same - I have yet to figure
out what the difference is, if any.  I usually say C139 because to the
best of my knowledge, all units with NA bands are C139s, whereas EMEA
band units have been observed with both C139 and C140 branding.

Please note that all C1xx phones are single-region, i.e., either EMEA
only (900+1800 MHz) or NA only (1900+850 MHz).  That's the downside of
these models compared to the triband GTA02 and Pirelli phones.

 What about the other phones oBB list as targets - is it reasonable to hope
 they will usably run freecalypso?

All other targets listed by OsmocomBB are Compal family members.  FC
already runs on the C139/140 and C155/156 subfamilies - these two and
not others because these two are the ones of potential use to me and
my family operating in the USA-occupied territories.  Getting it to
run on other Compal variants goes along the lines of we'll add support
for model X as soon as at least one user actually needs it.

 I'm guessing though that the gui code might be substantially model specific?

Yes, the UI hardware in general (not just the LCD as implied by your
reference to gui, but also parts like the ringtone generator) is the
stuff that varies more widely from model to model.  In particular, FC
support for C155/156 may remain a toy, rather than practically usable,
because these models have a ringtone generator chip for which we have
no docs.  OTOH, C139/140 use a piezo buzzer driven directly by the
Calypso, no extra chip.

My advice here is simple: for as long as C139/140 (which variant is
right for your part of the world, in terms of freq bands) are still
available, just grab one to make things easier.  If you can't get this
model, but some other is still available, then let's revisit the issue
at that time.

Of course the ultimate solution is for us to build our own FC phones,
and I already made a start down that path - but my current game plan
is to finish the software part, and then resume the hardware project.

2014-06-29 Thread Michael Spacefalcon
There is one more free phone project still kickin':

I somehow doubt that these new folks on the scene ( will
produce a phone with a baseband processor whose firmware is delivered
to end users in full source form.  At best they might match the level
of freedom one can get today with GTA04 (free AP + closed black box
modem), but more likely they will probably end up like blackphone.  I
looked on, and nowhere do I see any software source
download links, let alone hardware schematics - WTF?!  Do they
seriously expect people to fork over $$$ for a closed plastic box that
is just as proprietary as the standard run-of-the-mill Androids and
iPhones to which they supposedly offer an alternative?

Meanwhile, FreeCalypso is steadily progressing toward its goal of
running 100% free software on all 3 hardware targets: Mot C1xx,
Openmoko GTA02 and Pirelli DP-L10.  Just yesterday I finished
reconstructing the source for the required subset of TI's GPF OS
Adaptation Layer (i.e., writing new C code to replace the bits which
were available only in binary object form, replicating the original
logic flow extracted from disassembly), and today I've got GPF
integrated onto the fledging gcc-built firmware skeleton.  It's
running on my GTA02 as I type this.

I am not aware of any projects other than OsmocomBB and my own
FreeCalypso that have ever promised or done any work toward a phone of
any kind, dumb or smart, that can make or receive phone calls using
only Free Software, i.e., software that provides its users with the
essential Four Freedoms as defined by the FSF.  Yes, if one excludes
the baseband from the freedom requirement, then anything from a Samsung
device running Replicant to GolDeliCo's GTA04 will pass.  But for
some people that is not good enough, and if there exists a choice
between a more-free solution and a less-free one, why would you choose
the latter?

The OsmocomBB community seems to be interested only in security
research, aka hacking, whereas the goal of producing a usable phone,
if they ever had such a goal at all, appears to have been completely
abandoned.  Consider this one little factoid: OsmocomBB was first
presented at 27C3 in the last days of 2010; a video recording of that
presentation (by Harald Welte) is online.  If you watch that video,
you can see what the state of functionality was as of that date.
Well, here is a bit of breaking news: the level of functionality that
OsmocomBB offers for normal phone usage (as opposed to hacking) is
*exactly the same* today, in mid-2014, as it was at the end of 2010:
the phone can kinda-sorta connect to cell networks (not very reliably)
and can do calls and SMS for as long as it remains tethered to a PC,
with the GSM protocol stack running on the PC instead of the Calypso.
As evidenced by the video of Harald's talk, it did exactly the same in
December of 2010.  So what the heck have these people been doing for
the past 3.5 years??

In comparison, FreeCalypso got a much later start: I only succeeded in
obtaining the key starting-point materials when they were published in
the fall of 2013, less than a year ago, whereas Harald Welte and his
gang have undoubtedly had them many years earlier, probably before they
even started OsmocomBB.

If life circumstances (finances etc) permit me to continue working on
FreeCalypso without slowing down, then by the end of 2014 we shall
have fully free firmware with basic GSM functionality running on the
GTA02 GSM modem, and by fully free I mean full C source compiled
with gcc, no blobs or proprietary compilers.  The same fw will run on
dumbphone hw targets too, but will still be controlled by external
AT commands, no UI, hence only a toy like OsmocomBB.  Adding UI would
be the next step.

Because I would rather give an overly pessimistic time estimate than
give an overly optimistic one and then fail to deliver, I'll estimate
the time to fruition as follows:

* 2014-12-31: GSM fw fully running on the Calypso baseband, controlled
  by AT commands, which would be good enough for practical use on the
  GTA02, but a toy on the other targets.  Voice + SMS only; adding CSD
  and GPRS would be subsequent extra work.

* 2015-06-30: the above plus the UI layers to make a Calypso dumbphone
  with available schematics and no undocumented chips (e.g., Mot C139)
  work as a practically usable cellphone running 100% free software
  which any user can recompile from source and reflash at will.

(The above are estimates, not a binding contract; anyone interested in
 a firmer commitment in exchange for pay is welcome to contact me

So as you all can see, the goal of a phone that runs 100% free software
with *no* closed baseband is quite within reach.  Now back to your
regularly scheduled programming.

 Interesting results:
 +COPS: (1,T-Mobile ,T-Mobile,310260)
 If I'm not mistaken the above means that only T-Mobile is found.  

Yes, it does.  310260 aka T-Mobile USA is the only thing your FR can
hear in the PCS1900 band.  Because your FR is the 900/1800/1900 MHz
version (like mine), there is no reliable way to tell if any GSM
services exist in the USA-secondary band at 850 MHz.

If you feel adventurous, you can go to ebay and get one of those Mot
C139 phones I mentioned earlier - it's an ultra-basic candybar
dumbphone that was made either EU-only or US-only, each version
supporting the low and high bands for its region, so the US version
supports both 1900 and 850 MHz.

 Which I'm guessing implies that ATT have decided to turn off GSM 
 here. Which would be ... annoying.

Given that T-Mobile still provides GSM1900 coverage in your area (and
with good signal strength too, as far as I could tell from your
previous captured modem output), it seems to me that the proper thing
for you to do would be to close the feedback loop by promptly canceling
your ATT service subscription, and making sure to tell their customer
service exactly why you are no longer interested in their 3G-only
services which do no good for freedom lovers like us.

I've been a T-Mobile customer since 2003, and I've been quite happy
with their service and plans.  The latter have been greatly simplified
when, because they only care about selling data and give voice calls
away for free, they eliminated all counting of minutes and SMS texts,
and set their lowest-end, most basic plan at $50/month for unlimited
calls, unlimited SMS and unlimited 2G data as in GPRS - i.e., their
lowest-end plan gives us unlimited, all-you-can-eat use of everything
that our FreeCalypso phones/modems are capable of using.  (CSD calls,
which work very nicely, at least in SoCal, are part of the unlimited
calls deal too!)

More recently I have heard that some T-Mobile MVNOs apparently offer
the exact same thing for less per month: that MetroPCS I mentioned
earlier say they only charge $30/month, and their description sounds
like the exact same thing that costs $50/month directly from T-Mobile.
In my own case I'm not interested in switching because my plan is not
just for me, but covers all of my family members too, and I'm a
strong follower of if it ain't broke, don't fix it - but for someone
new who does not already have service with T-Mobile, looking into
these MVNOs would probably be a good idea.

After I send off this post, I'll make a quick trip to that MetroPCS
store I mentioned earlier, I'll bring my FR with me for testing, and
I'll ask them about Boston area.

T-Mobile GSM1900 coverage yet.  Yet..

I do have to agree that the problem Nick is having (FR working like a

sounds very suspiciously like the result of GSM cell shutdown, rather
than anything being wrong with the FR.  That is the reason I keep asking
Nick to try a T-Mobile SIM in his area - while both carriers have the
same GSM killing agenda in the long run, it is rather unlikely that
both of them would kill GSM in one specific spot at *exactly* the same

Open letter to FBI/NSA/etc: you guys might want to consider paying
T-Mobile to retain some minimal GSM coverage in Southern California,
just enough for one (1) user, so you can continue tracking my
approximate location.  For as long as I have working GSM (and you know
I almost never turn my phone off, so my sweetie can call me any time),
you can easily track my location with cell-site granularity, and if
you care to do some actual work (call me to cause my phone to transmit
continuously, then bring out your DF gear), you can pin-point where I
am even more precisely than that.  But I will never, ever, ever use a
3G phone, as a firm matter of principle, so if usable GSM service goes
away in my neck of the woods, then I won't have a cellphone at all: of
any kind, period, and then you will have no idea where I am at any
given moment.  Just some food for thought.

 No, it has worked fine (well, in fact) for the past couple of

Hence my worry about you possibly being the first victim of GSM

 I may end up doing that, but there isn't a T-Mobile store very 
 conveniently located for me,

I've heard that MetroPCS and Simple Mobile are T-Mobile resellers.
If you spot either of these two in your area, try going in there and
asking for a test SIM.

 so I'll at least try some fun logging of AT commands first.

When the modem is working normally, the AT+COPS=? command gives a
listing of all available carriers, so one can see what's available
beyond the specific SIM you've got.  But for some reason that command
only works after I issue a plain AT+COPS first, which is the command
to register to the default operator.  I don't know what will happen if
one issues AT+COPS and that operation fails: will AT+COPS=? work or
not?  I also have not yet studied the relevant part of the firmware
source, so I don't know whether the behaviour I see in this area is a
bug in need of fixing, or if there is some good reason it works this

One can also use the cell_log utility from OsmocomBB to list all
available GSM cells and their owners without having any SIM at all
(and without registering to any of these detected networks), but
because OsmocomBB is dominated by EUnians (not one soul from North
America in that gang), getting cell_log to work in the PCS band was an
incredible pita.  At least I did it on a dumbphone (Pirelli DP-L10);
trying to do it on a Neo would be even more pain..

 Similarly, let me know if you come to Boston. :)

See my question above as to the time window of your presence there.

2014-05-19 Thread Michael Spacefalcon
There is one more way to test/observe what 2G and 3G services and
carriers are available at a given location: by giving that AT+COPS=?
query command to a 3G USB modem stick that speaks AT commands.  I've
got a Huawei E303 (South American Claro branding), it is supported by
recent versions of the usb_modeswitch package, which puts it into AT
command speaking mode, and one can then run a terminal program on the
/dev/gsmmodem symlink it generates.  Giving this modem an AT+COPS=?
query returns the list of carriers that looks like this:



The 5 fields in each parenthesized entry mean:

- state: 2 means currently selected, 1 not selected;
- full name in quotes
- short name in quotes
- the true numeric ID sent by the cell network (the decoded names in
  the previous two fields come from a look-up table in the modem fw);
- 3G-added field not in the GSM 07.07 spec: 2 means 3G, 0 means 2G.

The example output above is from a location that has both T-Mobile and
ATT service, both 2G and 3G, but T-Mobile 3G in this location is on a
frequency this modem doesn't support, hence it doesn't show up in the
list.  The modem has a T-Mobile SIM in it, hence in the shown example
it is registered on T-Mobile 2G instead of ATT 3G.

To Nick - if you happen to have one of these 3G USB modem sticks or
are able to borrow one, you should try it at the location where you
are having FR woes and see what it shows.

 In the meantime, I tried running the AT commands with socat, but 
 didn't get very far.

I've never used socat (I use my own tool, see below), so I don't have
much to comment on that part, but the transcript you've posted shows
that you managed to catch some of the modem's output while it was being
driven by QtMoko (perhaps stopping QtMoko doesn't power the modem off),
and this output contains a smoking gun:

 +CREG: 3

The +CREG unsolicited response from the modem indicates its registration
status, and looking up the meaning of status code 3 in GSM spec 07.07
tells us that it means registration denied - aha!  So the GSM radio
signal *is* present, but when your FR tries to register to the network
it hears, the network actively denies that registration!  Two
possibilities come to mind:

Possibility 1: ATT GSM service went away (either a deliberate service
shutdown, or the tower simply went down for some random reason or
another, and they are in no hurry to fix it because it's 2G which is
only used by outlaws and freedom lovers like us), but T-Mobile GSM is
still present; your FR tries to register with the T-Mobile network,
but the latter rejects the ATT SIM.

Possibility 2: ATT GSM service is still there, and your FR is trying
to register to it because it's got an ATT SIM, but ATT has decided
to reject your FR for some truly nefarious reason, such as an IMEI ban
against an entire range of devices they don't like - I've read stories
on the web about ATT specifically pulling such BS.

See below on my proposed method for distinguishing between these two

 %CSQ:  18, 99, 2

%CSQ is TI's non-standard extended version of the standard +CSQ command
and unsolicited response; the standard +CSQ response gives two numbers,
while %CSQ adds a third.  I don't fully understand the meaning of the
3rd number yet, but we can ignore it for now.  99 in the 2nd number
position is a placeholder meaning that the modem has no BER information,
but the 1st number is the RSSI: received signal strength indicator.
Numbers like 18 or 15 seen further in your transcript look good to me.

 +CIEV: 1, 3

Yet another way by which TI's modem implementation returns the RSSI,

 The commands 'AT+COPS=?', 'ATE1', 'AT+CFUN=1', 'AT+CGMI' were 
 entered by me. I'm guessing I should have seen at least a 'OK' or 
 'ERROR' message, so maybe I'm using socat incorrectly?

Because I am the kind of guy who finds it easier to write his own
program than to learn how to use one that already exists, I've been
using my own ad hack tool called engcons to talk AT commands to the
modem in my Neo FR.  The engcons.c source is appended at the end of
this post; you'll need to compile and run it on your FR.  Use it like

# stop QtMoko
/etc/init.d/qtmoko-neo stop
# power-cycle the modem
echo 0  /sys/bus/platform/devices/gta02-pm-gsm.0/power_on
echo 1  /sys/bus/platform/devices/gta02-pm-gsm.0/power_on
# run engcons to talk AT commands
engcons /dev/ttySAC0 r115200

Once you do the above, you should be in a state where you can type AT
commands and see the expected responses.  Try AT+CGMI, AT+CGMM, AT+CGMR,
AT+CFUN=1, AT+COPS and AT+COPS=?, and post the results you get.

OK, good observation.  The problem is now narrowed down to the FR,
rather than network coverage in your area, your service subscription
or the SIM issued for it.

There is one more thing we need to check before proceeding further,
though.  That other phone you used to confirm your SIMs as good, what
kind of phone is it?  Is it 2G or 3G?  If the latter, please look
through its menus and see if there is an option to force 2G mode.
The reason for this exploration is to eliminate the possibility that
GSM (aka 2G) service in your geographical area stopped working,
knocking out Free Firmware phones while closed proprietary Apple/
Samsung/GTA04/etc still work on UMTS..

(In the event that some part of the world with a nonzero population of
 Free Firmware phone users does kill its GSM service, there are two
 possible ways for us to react to that development: either try to
 liberate one of the newer 3G+ phones/modems, or build our own GSM 2G
 network for our own use.  If/when this situation ever occurs in my
 part of the world, I will do the latter, as I consider GSM/2G to be
 superior to 3G crap both technically and morally.)

Assuming that your email TLD matches your location, you are doing this
in the UK, right?  Do you know if your service provider operates a
900 MHz GSM network, a 1800 MHz one, or both?

 Revision is:
 GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-Moko11
 So Moko11, I guess ;)

Any particular reason you have not yet upgraded to leo2moko-r1 aka
moko12?  While it is very unlikely that performing this fw update will
fix the problem, running fw with a published Corresponding Source and
a linker map listing will likely be a prerequisite for some of the
more advanced troubleshooting steps, so you might as well do it now..
 That's a good idea. I'm hitting a snag before I get very far, 
 though. Namely that I don't know which process is in charge of the 
 GSM, so which one to kill to stop the phone accessing.

According to this web page:

the command you need is:

/etc/init.d/qtmoko-neo stop

(Whether the intent is to talk manual AT commands to the modem or to
 reflash it, the step of stopping QtMoko should be the same.)

 lsof would probably tell me, but I can't install it because it's 
 tough to get the wifi to work (which I generally don't care about).  

Huh?  WiFi?  While you do need an ssh connection into the Neo, why
does it have to be WiFi?  Doesn't QtMoko support eth-over-usb
networking like the others?

perhaps you could try a T-Mobile SIM card just as a quick test?  If
you don't have one, just go into any T-Mobile store and ask them to
borrow a SIM for a few minutes to test in your phone while inside
their store.

Also if there is any chance you might visit California before you go

If you are using your FR as an oversized dumbphone, have you considered

ebay while they are still available - it is one of the models which I
am using for FreeCalypso firmware bring-up (along with the Neo FR and

the advantage of being a very simple dumbphone with full schematics

 I haven't been using my phone much recently, but it's always been

 I'm not sure where to go or what to look for to debug this. I've 
 restarted the phone multiple times without success.

What modem firmware version is this?

 Any advice?

Since the GSM modem is no longer an impenetrable black box, you could
try debugging the apparently misbehaving modem using standard Free
Software debugging methods: study the source and the documentation,
and make use of the modem debug interface accessible via the headset

Start by taking QtMoko high-level software out of the equation and
talking AT commands directly to the modem:

Try the AT commands shown on that wiki page, and tell us the results.
That right there might spot an issue.

If the modem behavior at the AT command level is that of failing to
register for no good reason, the next debugging step would be to look
at the debug trace output.  Get a debug cable, if you haven't already:

Put the debug serial channel on the headset jack with this command:

echo 1  /sys/bus/platform/devices/gta02-pm-gsm.0/download

Make sure the audio is routed to your Neo's earpiece speaker and not
the loudspeaker, to avoid damaging the latter or your ears.  Plug the
debug serial cable into the headset jack, and plug the other end into
your PC or other host computer running GNU/Linux or some other Unix.
Run the rvtdump utility from the FreeCalypso suite, e.g.,

rvtdump -l logfile /dev/ttyUSB0

With the serial cable connected, rvtdump running on the other end, and
1 written into that /sys/.../download node, power up the modem.  You
should get a bunch of debug output; tell us what you see.  (The -l
option will save this output into a log file, with a timestamp prepended
to each line.)  You should get more interested debug output when you
issue AT+CFUN=1 and AT+COPS commands which start the actual GSM
operation; tell us what you see at those steps as well.

If the above steps don't reveal anything amiss, next debugging steps
would be to examine firmware state variables in memory with fc-tmsh
and/or send special commands (called system primitives, enabling more
verbose traces and other debug functions) to the running fw with g23sh,
both of which are FreeCalypso tools operating via the debug interface
(called RVTMUX) presented on that headset jack.  If you are running a
firmware version such as leo2moko for which we have a linker map file,
we can examine every single variable that fw maintains, and the
system primitives provided by the GPF component (Condat's Generic
Protocol stack Framework) allows us to capture and examine every
primitive exchanged between GSM protocol stack layers: e.g., we could
see the exchange between L1 and L2, or between RR and MM, etc.

But let's see if you can manage the simpler steps above before I go
into details of what you should peek and poke with fc-tmsh and g23sh
tools - getting the simpler rvtdump working would be a prerequisite
for the more advanced tools anyway.

FreeCalypso progress update

2014-05-08 Thread Michael Spacefalcon
Hello project followers,

Just a quick update on where the FreeCalypso project stands.  I am
still reconstructing the full-source form of TI's Calypso reference
firmware, the one which we currently have only in semi-src form,
running on TI's Leonardo board and on the GTA02 modem.  How can one
reconstruct a full source from a semi-src (half src, half objects) in
which half of the original source is missing?  By finding matching
source pieces in other TI source leaks (the Peek LoCosto one mostly)
and reintegrating them one by one onto the reconstructed FreeCalypso
firmware skeleton.

There are a few binary objects in the Leonardo semi-src for which no
matching source could be found in any of the available leaks.  I am
currently working on one of these hard pieces: the OS Adaptation Layer
part of the GPF, the thin layer that sits between the Nucleus RTOS
microkernel and the higher sublayers of GPF.  GPF stands for Generic
Protocol stack Framework, and it is the foundation on which Condat's
GSM/GPRS radio protocol stack is built.  Back in the days when TI
actively maintained their firmware for Calypso, LoCosto and other
offerings in this family, the GPF code was already so stable and
independent of the rest of the firmware that it was distributed and
used mostly as binary libraries even inside TI, it seems.  Take the
LoCosto source for example: all of L1, L2 and L3 code is compiled from
source, but GPF comes from *.lib files that are pulled into the build
as blobs.

But fortunately we've been able to find the real C source for most of
GPF.  The Leonardo semi-src includes a few pieces of GPF C source
despite not actually using them in the build (which uses *.lib blobs
instead); the LoCosto find includes the source for some *other* parts
of GPF - once again, not actually used in the build which uses *.lib
blobs.  By putting together the GPF source bits from the Leonardo and
LoCosto finds, we now have the original C source for *most* of GPF -
and this source has already been integrated into the gcc-built
FreeCalypso GSM firmware tree.

The thin OS Adaptation Layer between Nucleus and the rest of GPF, and
the equally thin OSX layer between GPF and L1, are the only two parts
of GPF for which the original C source could not be found.  The first
out of these two (OSL) is needed in order build a test fw image with
GPF included, hence it is the part I'm working on now; the other (OSX)
should not be needed until it is time to integrate L1, so I plan on
tackling it at that time.

I am reconstructing the missing/lost source for the OSL part of GPF
from the binary object form, by a process of disassembly followed by
decompilation.  The disassembly step is automated with a special tool
I wrote for this purpose.  See the leo-obj subtree in this Hg tree:

Anyone who wonders just how much info can be extracted from these COFF
binary objects is invited to see for herself:

hg clone
cd freecalypso-reveng/leo-obj

Look at the *.disasm and *.ctypes files that will be produced, and
revel at all of the juicy C-level symbolic info contained therein.
All that stuff has been extracted out of the object blobs; the only
inputs to the tiobjd tool are the *.obj artifacts and some really
minimal hints in the *.hints files (see for yourselves how minimal
they are).  Who was it who said (some 2.5 y ago on this list) that the
ware in question is nothing more than useless blobs?

The next step is decompilation, and it's being done in the gsm-fw/gpf
subtree of the other Hg tree:

The gsm-fw/gpf/osl directory contains the C modules which I am
reconstructing from the above *.disasm through manual decompilation;
the other subdirectories of gsm-fw/gpf contain the rest of GPF, the
source for which has been found in the Leonardo and/or LoCosto semi-src.
The inc subdirectory contains all of the original GPF header files,
used by both the original sources and the ones I am reconstructing.

Peruse the two source repositories above to see where the project
stands; look at the commit history to judge the pace at which it is

Viva la Revolucion,

Joerg R. and others on this list have already explained quite well the
pointlessness of those IMEI changes when it comes to privacy.  There
is only one good reason to change one's IMEI: if some operator X blocks
your legitimate IMEI (or an entire range, like all known freeable

your IMEI to something that network will accept.

 and use anonymous SIM cards,

The anonymity or non-anonymity of a SIM card (i.e., whether or not you
have to show a govt-issued ID when buying or activating your SIM) is a
social problem, not one that can be solved by technical means.

Then my project is not for you.  It is for those who specifically want
a plain old cellphone (dumbphone) and not a mobile computer.

I already have a mobile computer which I'm reasonably happy with -
it's a Lenovo X200 ultraportable laptop, running Slackware.  But when
it comes to my cellphone, whether I use my old Mot V66 (unknown chipset)
or the Calypso-based C139 or Pirelli DP-L10, I am currently limited to
running Mot's or Pirelli's original proprietary firmware sans source,
with no ability to fix bugs or to tweak the UI design to my taste.  I
am very unhappy with this status quo, hence I am working to fix it in
a way that is within my ability: by reconstructing TI's standard fw
for modems and dumbphones from pieces (Leonardo+LoCosto+misc) and
making it run on the Calypso-based GSM devices I have available.

The related project of building a new Calypso-based dumbphone is
primarily in response to the exhaustion of the surplus supply of
ready-made devices.  If there were an infinite supply of Pirelli
DP-L10s with full schematics and with docs for that darned SPCA552E
chip, or of Mot C139s with unlocked bootloaders, there would be little
need to build new hw.  But the Pirellis are no longer available, and
even the stash I already have is of limited usefulness because this hw
is cripped by the lack of schematics and by those extra chips w/o docs.
Mot C139s are still somewhat readily available, but they are crippled
by the boot ROM being disabled at the board level, so we have to rely
on the original fw's bootloader instead.  If you buy a C139 on ebay,
it will be a gamble whether it arrives with a firmware version that
features an unlocked bootloader, or one which allows no known way of
loading our own code into the device.

Hence I plan on getting FreeCalypso fw running on a C139 and/or a
Pirelli as a proof of concept, then switching my attention to the
design of a new Calypso dumbphone free of Mot/Pirelli's design flaws.

Current status of the project: I've got the tool I wrote that parses
TI's COFF objects and produces disassembly listings which take
advantage of the symbolic information present in these objects (like
objdump from binutils, but more specifically taylored to TI's COFF
objects made by the TMS470 toolchain), and I am now working on
integrating GPF into my gcc-built FreeCalypso fw.  After GPF we'll
have L1, and then the bulk of the GSM protocol stack, yay!

 Also, routing voice traffic through the Intrenet is a way to not be 
 obliged to pay to carrier per minute or per text message.

So you would rather pay those same carriers per kilobyte instead?

I don't know how things stand in your part of the world, but here in
USA the carriers only want to sell mobile data services while giving
voice and SMS away for free - so it is the direct opposite of what you
are picturing: old-fashioned voice calls and SMS are free here,
whereas Internet packet data costs $$$.

 I think that carriers earn too much money just because not all the
 people still used to Internet.

But it's the other way around - those mobile Internet users are the
ones feeding the carriers' revenue stream, while outlaws like me who
eschew all that packet data crap and use old-fashioned circuit-switched
GSM services (yay CSD!) essentially get a free ride on that carrier!

 I believe, if we get Internet, then we can manage the 
 rest without carriers.

But why??  I *like* getting a free ride on my GSM carrier at the
expense of all those fools whose sky-high mobile Internet bills pay
for the upkeep of the infrastructure.

Don't need that much; 8 MiB of pSRAM (combined with NOR flash as part

Again, unnecessary complexity and bloat.  Mine will have 16 MiB of NOR

That sounds about right.

using TI's source code with proper power management (unlike OsmocomBB),
even a 1000 mAh battery can last a good while.

It is beyond me why would anyone in his or her right mind want to run
such complex, bloated and unreliable software on a *phone*, a device
whose primary purpose is to provide ultra-reliable voice communication
when all else fails, including emergency communication for potentially
life-threatening situations.

should NOT be called GTA-anything, because it is not GSM-TI-AGPS.  I
am not calling my Free Dumb Phone GTAxx either - while the 'G' and 'T'

All I know is that back in 2003 phones sold in USA with carrier

support began to be considered as a requirement.

Of course all those proprietary 3G+ smartphones (Apple/Samsung/GTA04/etc)
which we are all surrounded with typically act as quadband when they
go into 2G compatibility mode, but because they are proprietary black
boxes, only Cthulhu knows which band they are using and what is the
total set of signals they hear across their supported bands.  So I
still don't know for certain to this day what GSM services, if any,
exist in the 850 MHz band in my area.

 thanks, that makes me feel even more confident about my GTA02's 

I wrote earlier that I only use T-Mobile USA.  That status still holds,
but earlier today I did an experiment: I walked into an ATT retail
store with one of my Pirellis (900/1800/1900 MHz only, no 850, just
like EU-Freerunner), got a test SIM from the guy in the store (he
pulled it out of one of their demo phones), and inserted that random
ATT SIM into the Pirelli.  After displaying Searching... for a
little while, it worked!  The display read Cingular - so now we know
that the operator name decoding table in Pirelli's fw is the same as
the one we've got in our sources. :)  Going into the Engineering mode
menu confirmed that the actual network in this case (ATT in Southern
CA) is 310410.  A test voice call worked fine too.

So now we know that *both* GSM networks in USA (or at least in SoCal)
work OK with FreeCalypso GSM phones - although I would still recommend
T-Mobile to non-adventurous users, simply because it's been tested a
lot more extensively, including fun things like CSD.

Yes, that's exactly what I seek out of my cellphone too.  And that is
why I require having the source for all sw/fw involved in this telephony
function, so when it breaks, I can debug and fix it myself, long after
the original manuf has gone bye-bye.

 I had many phones before and 2 phones after 
 (N900 and now Jolla). None of them had any problems with SMS and telephony. 

My experience is different.  Until about a year ago, my true  trusted
phone was Mot V66 (a flip phone which I first got in 2003 if my memory
serves me right).  It mostly worked, but every now and then I would
notice the coverage status LED flashing red instead of green - I would
then open the flip to see what's going on, and the display would read
Unregistered SIM.  The only way to get it out of that wedged state
was to cycle the power; doing the latter would immediately show
perfectly good coverage with high signal strength - so it is obviously
a case of the fw getting stuck in some wedged state, rather than the
GSM network, although I reason that the triggering cause is likely
some network transient event.  This is on T-Mobile USA, Southern
California, 1900 MHz GSM band.

About a year ago I switched from this Mot V66 to the Calypso-based
Pirelli as my everyday personal phone.  Still running Pirelli's original
proprietary fw for now - getting FreeCalypso into a state where it can
drive a complete dumbphone rather than a mere modem is a big project
still in its infancy.  But it is still a freedom increment over the
Mot V66, as now I have a full understanding of the GSM chipset I am
using (the one in the V66 is something unknown to me), and because the
original proprietary fw is TI-based, there are plenty of things I can
poke at with my FC tools.

And guess what, Pirelli's proprietary fw exhibits the same strange
behavior with the phone inexplicably going out of service until
rebooted - but instead of Unregistered SIM, the LCD simply reads
GSM no service, just as if I went into a Faraday cage - except that
the GSM signal is perfectly fine, as the phone itself indicates when I
reboot it.  So it is the same case of the fw stuck in some wedged
state.  I don't know if the GTA02 modem running moko11 or leo2moko
suffers from the same bug or not - it manifests rarely enough that one
needs to be using the phone on an everyday basis to catch it.

 Openmoko is different - they never provided SW for reliable phone.
 And even 5 years after there is no good kernel for Freerunner.

And why has no one in the community produced such a good kernel in all
these 5 years?  One probable reason is because the brightest and most
talented kernel hackers, those most qualified to produce such a kernel,
have left this community in frustration (moved on to other life
interests and pursuits) when no liberated/NDA-broken GSM fw appeared.

2013-10-13 04:08:54 CEST came a little too late, I'm afraid - by that
point all those best and brightest have already departed this
community for good, doing something else for fun in their lives.

 2.6.29-rc seems 
 quite stable but the patch against mainline is horrible, besides it's power 
 management is worse then it could be. 2.6.39 has hardly nearly unreproducible

 Now we have free firmware which is cool, but the usablity of the phone hasnt

Hearing stories like this (both now and during the 2y I spent looking
for the TI fw deliverables) helped convince me that I would be better
off spending my time building a free dumbphone with no Linux at all,
rather than whipping GTA02 Linux AP software into shape so it could

If you come to Southern California, I can confirm that you can go to

Yup, that's the band I've been using here for all my cellphone-using

Again, this is with a T-Mobile SIM card, connecting to T-Mobile base

Prior to that announcement, i.e., at 04:08:53 CEST and for the 6y of
Om community history prior to that, the Unfree-runner was a proprietary

But I'm afraid that the liberation came a little too late: I keep
hearing the number 15k units made and sold being tossed around, but
of those 15k units, after we subtract those which were cannibalized

saying I am only half-pregnant!

I would argue that Om's biggest mistake, the one that led to their
downfall, was the silly half-pregnant attempt to do it legally.  It
should have been done as a 100% explicitly-illegal black market
operation instead.  Hiring law-abiding Germans to run the show was the
#1 mistake - the operation should have been run by the Chinese/Taiwanese
instead.  Contrary to what has been said, they did NOT have to sign
the NDAs as they did - surely if the show were run by Chinese/Taiwanese
without a single German on staff, they could have simply used the warez
floating around that giant country.  (As just one data point, the
TSM30 source - *full source* - was published in 2004, at least 2y
before Om came onto the scene.)  The Calypso etc chips are easily
sourceable on the grey market: some legit company buys 100k chipsets
from TI, makes 90k phones, the remaining 10k chipsets sell on the grey
market w/o unnecessary questions.  The physical production of phones
should have been done in some unmarked basement without any legit
company attached, so there would be no one to sue, and the distribution
(sales) should have been done through the same channels used to market
and sell alternative medicine products like cocaine and heroin.

But oh well, history is what it is.

 the knowledge about NDA restrictions of GSM components is still today  
 only in some geek's mind.

Huh?  I'm afraid I don't follow what you are saying here.  The GSM
mini-Wikileaks collection at now has
*everything* related to Calypso and other related chipsets from TI,
probably more than Om ever had.  The documentation for the actual
hardware components has been on my FTP site since the fall of 2011
(downloaded from where it had been available to those who can
navigate in Chinese for much longer), and we now have TI's TCS211 fw
deliverable semi-src no different from the one Om had, if we make the
reasonable assumption that all of TI's chipset customers got identical
or near-identical fw starting point deliverables.

We even have an equivalent TI deliverable (hw docs + fw semi-src) for
their LoCosto chipset (one of Calypso's successors), and while I have
no desire to use LoCosto instead of Calypso (LoCosto has some freedom-
reducing improvements), the LoCosto semi-src is something like 95%
real C source (unlike the TCS211/Calypso/Leonardo one on which the
current leo2moko port is based), hence I plan on using chunks of code
from the LoCosto source to replace some of the binary-only libs in the
TCS211 version.

So the liberation part of the FreeCalypso project is now 100% done;
what remains now is the (quite hard) purely technical work of
reintegrating all of the pieces back together to build the fw using
gcc without any Weendoze tools or blobs.

 As long as there are big players like government and companys, a 100%  
 open mobile will never happen. Never.

Of course it will never happen legally, but so what?  We can build it

 but concerning technical effords, he was very  
 insistant and pushed it as far as writing a tool for easy change of IMEI  

Just in case it isn't already clear, that IMEI change kit came about
merely as a *side product* from my main work seeking to produce a
better-than-OsmocomBB totally free GSM phone firmware.  In TI's fw
architecture, the actual GSM code runs more or less as an application
on top of a quite rich RTOS environment, and getting this RTOS
environment (by which I mean not just Nucleus, but also RiViera, RVT,
FFS, ETM and other components) fully working and fully under our own
control is a prerequisite for tackling the actual GSM code.  This RTOS
environment just happens to include a full-featured Unix-like file
system (TIFFS), so naturally tools are needed to operate on this file

The IMEISV is just one data item stored in TI's GSM device file system,
and because of its forbidden fruit status, a lot of people have been
asking for a way to edit it freely, hence it was quite natural to take
several FreeCalypso tools (written for the primary purpose of free GSM
fw development and debugging) and string them together into a very
hacky kit for editing the FFS on GTA01/02 modems.

 without having full access to NDA-infos.

The 4 TI source leaks on which my work is based are TSM30, LoCosto,
MV100 and Sotovik, in the order of discovery/liberation.  The real
thanks go to those who have brought all of these leaks out into the
public - as Comrade Stalin said, the country needs to know its heroes.

But in the case of TIFFS specifically, I didn't have a source for this
fw component until the MV100-0.1.rar find, and believe it or not, I
actually reverse-engineered that FFS format on my own (by staring at
hex dumps of flash read out of my GTA02 and Pirelli phones and
reasoning how one would implement a writable FFS given the physical
constraints of NOR flash) just a few days before I found that MV100
source leak!

Just in case I haven't already made it fully clear, that is exactly
the focus of my work.  The IMEI change kit was/is merely a byproduct
made by stringing together the tools which were written and are needed
for main GSM fw development.

 because my FR sometimes fails in accepting calls, often fails in
 receiving SMS, not always works up from suspend, the people I call are
 blaming me for my poor voice, etc.

With the current leo2moko firmware, I am quite confident that the GSM
modem in the FR works the way it should, no major flaws.  The fw in
question does have a bunch of binary blobs in it, making it very hard
to modify some things until we deblob it, but even these blobs are in
the form of COFF objects with full symbolic information, parsable with
the objdump utility from GNU Binutils built with the needed patch, so
while having very limited ability to modify them at the present
moment, we can still examine these blobs with a high level of
transparency.  And as you can probably guess, I have already examined
these blobs quite extensively, and hence have a high level of
confidence in the quality of the fw.

So with the modem no longer being the black box which automatically
takes the blame for any and all problems with phone functionality, the
finger of suspicion now points at the Linux application processor
software on the FR.

In my opinion, the problems which reduce the usability of the FR as an
everyday cellphone stem from the unnecessary complexity of the Linux
AP.  If all I want is a cellphone for making and receiving phone calls
(plus SMS), why in the heck should I have to deal with the enormous
extra complexity of a Linux computer built into that phone?

IMEI changing kit for GTA02

2014-02-07 Thread Michael Spacefalcon
Hello fellow freedom lovers,

I have just released the first version of the kit that allows a Neo
Freerunner user to set his/her IMEISV to any value of his/her choice.
Download it here:

Operating instructions are inside the tarball.  The way in which this
kit works is completely independent of what firmware version you have
in flash: it can be moko11, leo2moko, or even blank or corrupt flash.
(Just like with fc-loadtool, the chain starts with Calypso's on-die
boot ROM, i.e., the wonderful hardware unbricking feature TI gave us
in this baseband chip, similar in principle to FR's NOR U-Boot which
is extra hardware just for unbricking.)

Please also note that many vendors' standard proprietary firmwares
include undocumented AT commands for setting the IMEI, and as my
experiments indicate, moko11 appears to be one of them:

However, I do not recommend using that AT@SC command, as the half-baked
implementation does not make the proper distinction between IMEI and
IMEISV, and the last 16th digit of the complete IMEISV (which is what
the modem actually uses and sends over the air) ends up being set to a
random value that is an artifact of the obfuscation scheme.

As an example, the original factory IMEI of the GTA02 I use for FC
development is 35465101-961584-0; the original factory programming of
the complete IMEISV is 35465101-961584-00.  However, if one uses that
AT@SC hack to change it, it is then impossible to revert the complete
IMEISV back to this original setting using the same AT@SC command!  If
one feeds the correct obfuscated AT@SC string for setting
35465101-961584-0, the full IMEISV gets set to 35465101-961584-01
instead of the original factory 35465101-961584-00.

In contrast, the FFS editing kit linked above allows you to set all 16
digits of the IMEISV to whatever you choose; the kit provides the
mechanism and you decide on the policy for what the SV digits should be.

However, considering that those with a desire to play with their IMEIs
would probably find an AT command much more convenient than the rather
cumbersome (albeit powerful) XRAM-agent-based mechanism presented in
my current kit, I plan on making a new version of leo2moko that will
include a new AT command for setting the IMEISV.

I will not be replicating the obfuscated AT@SC command, instead it
will be a different AT command that sets all 16 digits explicitly and
works without any obfuscation.  The syntax I propose is:


If anyone has an argument for a different syntax, please speak up now.

Considering the time proximity between this hack and the moko5-moko6
change in which you (not you personally, but the company) went backward
from the sensible approach (used in most other TI-based products too)
of storing configuration items in FFS to the non-sensible approach of
hard-coding them in the fw, let me make a guess: the crappy Weendoze-
only host tools for development and production which TI gave you (for
FFS programming in this case) were unreliable, and you were looking
for a way to avoid needing to do any FFS programming through the RVTMUX
interface (TI's official way) at all.  Of course the IMEI is one item
which can't be hard-coded in the fw, and if you didn't want to (or
couldn't) use the proper RVT/ETM-based method of programming, then
you had to hack in some other way, such as a special AT command.

But I assume that the issues with TI's production testing and
programming tools must have been solved in time for GTA02A7 mass
production, as my unit came with a /pcm/IMEI (IMEISV really) setting
which cannot be programmed via that AT@SC hack, only via the proper
RVT/ETM channel.

I also find it cute that all mass-produced GTA02 units (at least the 4
that have been liberated so far: mine, David's, Norayr's and Giacomo's)
came with a few files in FFS (/pcm/CGM[IMR]) which are not used by any
of your fw's from moko6 onward, only by moko5 - surely flashing a GTA02
back to moko5 is NOT recommended (I even remember seeing admonitions
somewhere to never do that), yet those files seem to be there just to
support those people who might do that...  Wasn't it your inability to
write these strings into FFS reliably that made you go back to hard-
coding them?

When I made leo2moko from TI's standard Leonardo baseline, I had to
add a bit of extra code to display these CGMI/CGMM strings with some
extra wrapping around them.  If one were to run TI's totally vanilla
code on a GTA0x modem with this MokoFFS factory programming,
something in their ATI layer gets confused because apparently it
expects the strings to be wrapped in angle brackets, but the strings
featured in /pcm/CGM[IMR] in factory-programmed MokoFFS don't have
those angle brackets.

Oh well, history is what it is.

 It actually been a weird secret AT command to change the IMEI, it claimed
 in changelogs that it had some really weird formula to add birthday^5 to old
 IMEI or sth and append that to the new IMEI, for authentication - and it
 never worked afaik.

So I assume we are in agreement then that this secret AT@SC command
is NOT recommended for use?

Anyone who needs to change their IMEI for some good reason (because
they need to be ultra-anonymous when going from one disposable prepaid
SIM to another, or because they need to use some GSM network that
wrongfully blocks their FR's factory IMEI) should use the kit I have
just published.  This method does work - I've tested it on
T-Mobile USA :-).

I have yet to learn what these files under /gsm/l3 are for, so I don't

rewritten by the modem quite frequently in normal operation, so they
are definitely in the dynamic state category, not factory-programmed

 diff -r michael-ffs/gsm/rf/afcdac my-ffs/gsm/rf/afcdac
 Binary files michael-ffs/gsm/rf/tx/levels.900 and my-ffs/gsm/rf/tx/levels.900

These are the interesting ones: all files under /gsm/rf are calibration
data recorded at the factory and never changed afterward, so the diffs
we are seeing here are the measured physical variations from one
produced unit to the next.

The next natural question here is how great or small these differences
are, i.e., the magnitude.  To answer that, we need to look at the
actual content of these RF calibration files.  They are all binary,
and are read directly into RAM data structures belonging to the Layer1
code in the firmware.  I will give these structures their deserved
scrutiny when I reach the point of deblobbing the L1 code and
integrating it into my gcc-built FC GSM fw - IOW, not yet.

In the meantime, I think it would be a good idea to collect the content
of this /gsm/rf directory subtree from as many Neo units as possible -
understanding the actual magnitude of per-unit differences in these
calibration values would help us provide the best possible recovery
for anyone unlucky enough to lose their FFS, and may also give us an
idea as to what to expect in this department when the time comes to
build new FreeCalypso phones and modems.

Because all files under /gsm/rf are written only on the factory
production line and not afterward, there is no personal information in
there: nothing read from your SIM(s), no history of network connections
or the like, and no IMEI or other identifying numbers, just measurements
of physical process variations.  Therefore, there should be no privacy
problems in publishing this data.

If you would like to contribute your RF calibration data to public
knowledge, you can make a .tar.gz from your extracted /gsm/rf subtree
(just that subtree, don't include any other directories which may
contain private personal info), send it to me, and I'll put it on - I'll make a new directory for this calibration
collection.  Oh, and inside that tarball, add a note indicating
whether the unit in question is a GTA01 or a GTA02, and whether it is
the 900+etc or the 850+etc frequency band version.

To repeat: if you choose to do the above, be sure to extract the
content of your FFS with mokoffs xtr and then make a .tar.gz of just
the /gsm/rf subtree - you probably do NOT want to publish your
complete raw flash dump, as there's a lot of personal info that can be
extracted from a complete FFS image.

 Binary files michael-ffs/pcm/IMEI and my-ffs/pcm/IMEI differ

TI's DAR component (Diagnostics And Recovery) is coming up next to be

One part which I have yet to learn is how the SMS receiving path works.

soon - be patient.  (Or if you are impatient, feel free to follow the
project as it happens in the Mercurial repository on Bitbucket.)

Yes, I said IMEISV, not just IMEI - if you don't know the difference,
read it up on Wikipedia etc.  Even though the file in TI's device file
system is named /pcm/IMEI (at least on older modems like Om's which
don't use the so-called IMEI protection), the number it actually
stores is the IMEISV.  The file is (or should be) exactly 8 bytes long,
storing the 16 digits of IMEISV, two digits per byte, and the GSM
protocol stack into which this number is fed (by way of a function
called cl_get_imeisv(), grep for it in the leo2moko source) treats the
last two digits (stored in the last byte) as the SV field, not the
Luhn check digit.

That being said, it looks like both Openmoko/FIC and Pirelli/Foxconn
set the SV field of their factory-programmed IMEISV numbers to x0,
where x is the Luhn check digit for the IMEI part, such that one can
cheat: take the 16-digit IMEISV, drop the last digit, and treat the
remaining 15 digits as if they were the classic IMEI.  (Such
cheating is what my current leo2moko implementation of the AT+CGSN
command does - I made it match Om's functionality before I realized
that /pcm/IMEI is really IMEISV.)  A more reliable way to retrieve the
complete IMEI information on any TI-based modem is to issue an ATD*#06#
command: it will return a 17-digit number consisting of the 14 digits
of the IMEI proper, the Luhn check digit, and the 2 SV digits.

 In addition it would be interessting for me (in times of surveillance)
 whether silent sms (stealth ping) could be recognized and a report be
 dropped to the mobile phone. Also the change to non-encrypted transfer
 would be a similar event which might occure due to an IMSI catcher, so
 generating a message (SMS?) warning the user would be helpful.

Before we can implement the alerting functions you are asking for, we
need to liberate the GSM protocol stack first.  The current leo2moko
fw has this protocol stack in a bunch of binary object libraries, as
that's what TI provided in the TCS211 (Leonardo) deliverable.  Full
source forms of closely related versions are available through the
TSM30 and LoCosto leaks though, the latter being more promising - hence
the current FC project plan is to try lifting the g23m* code layers
from the LoCosto version, and see what we get.  But there is a bunch
of other preparatory work that needs to get done before we get to that

 Also: Could the gsm module be made working without a SIM, i.e. just by
 providing the necessary values like IMSI and Ki?

Sure thing, and OsmocomBB already supports such usage.  But where are
you going to get a Ki that is recognized as valid by the GSM network
you wish to use?  And what would the corresponding phone number

that (as David discovered experimentally) the combination of
{Neo FR loudspeaker enabled} + {headset jack Calypso access enabled}
is rather unkind on the loudspeaker, and on the operator's ears.
(Look at the audio circuits in the public GTA02 schematics to see why.)
However, the take-away should NOT be all audio is bad when doing any
Calypso hacking - instead it can be fine-grained:

1. One needs to ensure that the loudspeaker amplifier is off when
   using loadtools via the external serial cable method.  But the
   state of the audio subsystem absolutely doesn't matter if you are
   running loadtools from the AP and are *not* enabling the download
   channel via /sys dingling.

2. In some advanced debug scenarios (and I do mean advanced, as in you
   actually digging in / debugging the guts of the GSM protocol stack,
   and not just flashing prebuilt images from my FTP site) it can
   actually be quite useful to have the headset jack Calypso access
   channel enabled (with the cable going to the FC developer's laptop
   running rvtdump/rvinterf/fc-tmsh etc) while the modem is running
   normally, even during a phone call.

If you need to debug the Calypso via TI's RVT/ETM interface (presented
on the 2nd UART wired to the headset jack on the Neo) *while the modem
is making a phone call*, it is possible to have this download (or
debug) serial channel enabled while audio is also enabled at the same
time.  The trick is that in this scenario, the audio must be routed to
the earpiece speaker, and *not* to the loudspeaker, and most certainly
not in the analog headset mode.

This latter scenario is where FreeCalypso tools do need to play nicely
with Qtmoko/SHR/etc - it would be very useful to observe the RVT/L1/G23
debug output from the modem on the external serial port (or to send
active ETM commands to it via the same interface) while it is being
driven normally by Qtmoko/SHR/etc.

 Better idea - use the special distro (I used Qtmoko as a starting point)
 with or without the cable - or else build your own single purpose
 boot_and_run_from_sdcard system.

Yes, for loadtools operations (saving FFS dumps, flashing different
firmwares, coming-soon in vivo FFS/IMEI editing kit) David's offering
seems like a better choice.

Fun with IMEI (was testing the free calypso software)

 Does anyone know what will happen in a cellular network where there is

: no technical but organizational. Usually that IMEI gets an instant ban, and
: a fat bold red alarm logline in carrier's network logs.

Yup, if all of us were to use the same IMEI number, it would be far
too easy for our enemies to ban that one single number.

 I mean, MAC address is used on a physical layer, so if two network
 cards connected to the same switch have same MAC adresses, network
 won't work. I guess switch will down both ports connected to those

The analogy between IMEIs and Ethernet MAC addresses is a good one
from a manufacturing/management perspective, but not in terms of
network protocol usage.  Unlike MAC addresses, IMEIs are not used for
any kind of addressing or routing anywhere in the network, only as a
management identifier that is unnecessary in the strict technical

But from the perspective of a device manufacturer (which I will become
soon, hopefully), IMEIs are just like Ethernet MAC addresses: the
nominal requirement is that each be world-unique for all time (a rule
that gets broken in reality with both MAC addresses and IMEIs), a
manufacturer has to buy a range (supposedly fresh and unused) from a
central registry, and then number individual produced units out of
that range.

 But I don't know how IMEI's work. Are they technically necessary so
 that 3G/gsm network can be operational, or they are only used to
 identify (and track) customers by devices?

The latter.

Before everyone starts changing their IMEIs just for the heck of it,
let's analyze *rationally* how tracking works - or rather, what is the
total set of data elements available to carriers (and their gov't
partners etc) for tracking users, and how these data elements inter-

If you like maintaining a long-term-constant phone number at which
your family and friends can reach you (i.e., the whole purpose for
having a cellphone, at least for me), and you have a long-term-stable
SIM card associated with that long-term-constant phone number, then it
doesn't really matter if your IMEI is also constant or if you send the
output of a PRNG (or even a TRNG) to the network as your IMEISV every
time your phone/modem fw does the register operation.  The constant
SIM card with its IMSI, as well as the associated MSISDN (phone number
for your family and friends to call you at), is what tells the network
that you are still the same you, no matter what device you use or
what IMEISV it transmits.  Yes, you can deregister from the network,
then re-register with a different IMEI, making it look like you turned
your phone off, moved your SIM card to another phone, then came back
online with the latter - but what would be the point?

Instead, there are only two scenarios I can think of in which it would
make sense to change the IMEI of a GSM device:

1. If you really want to disappear w/o trace, such that you discard
   your old SIM, get a new SIM (prepaid, presumably) with a different
   phone number (and deliberately make yourself unreachable at your
   old one), and you want to make it look like the user of the new SIM
   is a different person from the user of the old SIM - in this case
   the same IMEI would indeed give you away, so you might want to
   change it in this case.

If the above applies to you (and it does *not* apply to me, as changing
phone numbers constantly would defeat the whole purpose of a cellphone
for me), then you need to be careful to change your IMEI *at exactly
the same time* when you change your SIM - if there is any time skew
between these two changes, such that a network sees {old IMEI, new SIM}
or {new IMEI, old SIM} at any time, even just once, your anonymity
effort will be instantly brought to naught!  If you want to do this, I
would recommend pulling your old SIM out first, throwing it away, then
doing the IMEI changing operation on the SIM-less modem, and then
finally inserting your new SIM.

2. Changing one's IMEI may be necessary if your legitimate IMEI from
   the manufacturer of your GSM device has been wrongfully banned or
   blocked by some GSM network you wish to use, and you need to use
   some non-blocked IMEI in order to get on the network.

The wrongful ban scenario is particularly frightening when applied to
whole classes of devices, rather than individual units.  The first 8
digits of the IMEI comprise the Type Allocation Code (TAC), which is
supposed to be allocated per each device type.  Hence if all
manufacturers involved played by the rules (of which I have no
knowledge), then every IMEI beginning with 35278901 is supposed to be
a Pirelli DP-L10, every IMEI beginning with 35465101 is supposed to be

 Not recommended and not entirely correct procedure but nevertheless should
 sort of work, yes. You might want to edit the IMEI to what yours been, before
 (or after) you flash that alien calib data.

I still have a lot of learning ahead of me in this department, but per
my current understanding, the purpose of RF calibration is to measure
those physical variations which exist from one produced unit to the
next, and to record these measurements (or some values derived from
the measurements) in per-device non-volatile memory, such that the
modem firmware can then take account of and compensate for these per-
device differences.  I'm guessing it has something to do with non-
linearity in the amplifiers, process variations in the ADCs and DACs,
temperature sensitivities etc.  This document from TI attempts to
explain some of it:

So my current understanding is that at least some of the calibration
values will differ from one unit to the next, and I reason that taking
the values from one unit and using them on a different unit may cause
some poor RF performance, or out-of-spec operation in terms of Tx
power levels perhaps.  I have no way of knowing just how much
difference there is between one GTA02 and the next, and hence what
would the magnitude of ill effects from a calibration transplant be.

A good experiment would be to compare the calibration values (properly
programmed at the factory, presumably) read out of different GTA02
units.  The flash dump from my GTA02 can be found here:

I made that dump from my GTA02 back in 2013-04, and put it on the FTP
site in 2013-07, long before the recent project breakthroughs.  The
first 0x225594 bytes of that flash image (just under 2.25 MiB) contain
the moko10 fw image (what my FR came with); the interesting part (the
FFS) starts at offset 0x38.

Using the new tiffs/mokoffs tools I just wrote (get them from the Hg
repository on Bitbucket or wait for my coming-soon tarball release),
we can examine the content in this FFS image.  Let's start with the
basic vital stats:

$ mokoffs -f flashdump.bin blkhdr
Block   0: age , type/status AB
Block   1: age , type/status BD
Block   2: age , type/status BD
Block   3: age , type/status BD
Block   4: age , type/status BD
Block   5: age , type/status BD
Block   6: age , type/status BF
$ mokoffs -f flashdump.bin fsinfo
Active inode block (AB) is block #0
Root inode is #1
Root inode (format) name: /ffs-root

(mokoffs is a trivial wrapper around tiffs that spares the user from
 having to specify the 64x7 FFS organization argument every time, and
 -f means that one is looking at a complete flash dump, rather than
 just the FFS sectors - hence the tool needs to go to offset 0x38.)

 Hi David, Michael, all,

 little piece of freedom rising!

You're welcome. :-)

 I'm still not brave enough to risk my only (I mean in all my life time
 so far) mobile phone, but I will soon ;-)

There is nothing at risk really - if the leo2moko firmware doesn't
work for you for some reason, you can always revert to moko11, using
either our flashing tools or the official moko11 flasher.

Even in the case of the FFS with the RF calibration values etc, there
is absolutely no danger of corrupting this FFS if you issue loadtool
commands exactly per the instructions.  Saving a backup copy of the
FFS sectors is a precaution just in case you erase or write to the
wrong part of the flash.  If you have this backup saved, you can
always restore it.

In the absolute worst case scenario imaginable, if someone does lose
their RF calibration values and has no backup copy anywhere, you
should be able to send your FR to some lab to get it recalibrated.  I
don't offer such service currently because I haven't acquired the
necessary RF test equipment and process knowledge yet, but when I
start building my own Calypso phones, I will obviously need to get
them calibrated, and once we have the knowledge and the setup to do
it, Harhan Engineering Co. will also offer recalibration services to
Freerunner users.

 By the way, I think that your work, with the right notes about being
 experimental and so on of course, should also be in the official wiki.

As much as I would love to see it happen, I doubt that the powers
controlling that wiki will ever allow it.

 A small question about the procedure you describe: is the t191 cable
 only needed to backup the vital parts of the calypso memory or also to
 write the new firmware?

Both if you use the uSD system which David just released; neither if
you get FreeCalypso loadtools running on the Linux processor of your
FR like Norayr did.

Oh, and just to be clear as to exactly what the vital parts of the
calypso memory in question are: the only entity that lives in the GSM
modem's flash memory besides the firmware image (which is exactly the
same in a device as it is on the web at the official download URL) is
the flash file system, or FFS.  The FFS in Openmoko's modems takes up
exactly 448 KiB of flash space (64 KiB x 7); per TI's design it is
structured like a UNIX file system (directory tree, forward-slash-
separated pathnames, case-sensitive etc) and stores a bunch of things:

* The modem's IMEI;
* RF calibration values;
* ID strings which say that your device is a Neo1973 GTA02 made by
  FIC/OpenMoko - Om's late firmwares (moko10/11) appear to not use
  these strings from FFS (fw returns hard-coded strings instead), but
  my leo2moko fw returns the strings from FFS following TI's canon;

* Some dynamic data written into the FFS (the fw always mounts the
  FFS with R/W access, TI's fw has no concept of a read-only mount
  for the FFS) during the operational lifetime of the modem: history
  of what SIM cards this modem saw, dialed/received/missed calls, and
  probably received SMS as well - I have yet to play with the latter.

Just this weekend I wrote a new utility for examining FFS images read
out of TI-based GSM devices (our beloved FR being one of them); this
new tiffs utility (with mokoffs and pirffs wrappers) supercedes my
earlier mpffs-* tools I wrote and released last summer.  The new
utility allows one to list and extract not only the current file
content of the FFS (i.e., what one sees when mounting the file
system normally), but also those files which have been logically
deleted or overwritten, but not yet reclaimed, i.e., not truly gone.
Hence the tool can be used to do forensics on Freerunner modems - I
suspect many of you probably never thought about the modem's flash
memory remembering the history of what SIM cards you had in there,
what numbers you called or received calls from, and probably your SMS
exchanges too...

The just-described utility currently lives in the freecalypso-sw tree
on Bitbucket:

Look in the ffstools directory.  Now I need to write some more
documentation and make a release tarball for the FTP site.  Stay
tuned; I'll post here when I make that release.

 By the way, yes, a distro able to flash and back-up everything without
 additional cables would be very appreciated.

Of course...  Shortage of qualified volunteer manpower is our only

 That's a bold misconception. OM wiki isn't censored, it just gets cleaned of

But I still think that it would be better for FreeCalypso to have its
own identity that is separate and independent from Openmoko, i.e.,
its own mailing list, its own website (wikified or otherwise) etc.

As a result of my involvement on another mailing list (on a topic that
is totally unrelated to mobile phones), I became aware of this document
from the ISO Technical Committee on terminology:

Simply put, the authors of the above statement from ISO TC37 emphasize
the importance of using terms which have a 1:1 mapping to the concepts
they are meant to stand for, i.e., 1 concept = 1 term.

As you and others have made it perfectly clear on numerous occasions,
the term Openmoko was never meant to stand for the concept of free
(or open) GSM modem; instead this term (according to you and other
high-standing community members, which I obviously am not) stands for
a different concept, namely that of a free application processor with
a black box modem attached as a peripheral.  And because the name
Openmoko rightfully belongs to you and your former boss Sean Moss-
Pultz, it is not my place to try to change its meaning.

(In fact, Dr. HNS is effectively invoking this term=concept equivalence
 of Openmoko = free AP with a black box modem as a peripheral when
 he asserts the legitimacy of his GTA04 product as a non-downgrade
 successor to Om products.)

But I am working with a completely different concept, namely that of a
free GSM device, be it a modem or a complete dumbphone.  And because
it is an entirely different concept than that which is mapped by the
term Openmoko, by the principles of ISO TC37 my new concept calls
for a new term for referring to it.  Hence the name FreeCalypso was
born: I came up with this name about this time last year, following
exactly the line of reasoning I've just outlined, and my first public
announcement of FreeCalypso was this one:

The FreeCalypso project is very much in need of its own web/list home
under the domain name, which currently features only an FTP
site.  My desire is to create a host first, hosting
Mailman mailing lists exactly like Openmoko and almost all FOSS
projects and technical communities have nowadays - anything else would
be seen as substandard, and therefore unattractive to me.  A website
for FreeCalypso (wikified or not) can be created later, but my first
focus is on the lists host on which we can create a proper new mailing
list for FreeCalypso.

And because I already have my own physical datacenter on my own
physical turf, I *will not* buy hosting from someone else who would
ask me to agree to their TOS or AUP or the like - hence my only option
is to use my own physical hardware.  A SAS JBOD chassis is already on
its way to me from ebay, already paid for; the drives are next - as
soon as I gather the cash to buy 6 SAS drives of some non-laughable
capacity (I refuse to use SATA, and I desire 6 drives to start with
for a raidz2 ZFS configuration - I'll be running OpenSXCE), I will
finally have the necessary hw, and will begin the setup/configuration

 There are tradeoffs everywhere.  I think that having a 100% free

Hypothetically speaking, if someone would like to have a device in the
Neo FR form factor that combines a FreeCalypso modem with an up to
date AP (application processor) subsystem like that in the GTA04,
there is nothing to stop you (that's an abstract you, not directed
at anyone in particular) from building such a hybrid device.  Calypso
and its companion chips are still available on the Chinese surplus
market; the 100 chipsets I bought some months ago most certainly
weren't their last.

But I doubt that someone would want such a device badly enough to
invest the massive amount of time, effort and money such a project

to actually (want to) build a new phone (or a mobile device of any
kind) based on the ancient Calypso, but it just so happens that I want
a dumbphone rather than a smartphone (or mobile computer or
whatever you want to call it) in my pocket, and naturally I'll be
building the device which I would want to use myself...

Oh well - when I do build that dumbphone for my own personal use and
enjoyment, it will also have a side effect of a known-working Calypso
reference design (quad-band!) becoming available for anyone to reuse,
so at that time (probably in a few years) we can look into combining
this FreeCalypso modem with something like Neo900 for the AP subsystem.

 I see no reason why one project should feel like the other is a threat.

It's the destruction of GTA02s entailed in the process of making GTA04s
that sets me off.  Some months ago (or was it a year or two ago?)
someone here posted about how he wanted to use GTA02 motherboards as
wall decorations or somesuch - now THAT kind of waste should be
criminally punishable!  If you feel that your Openmoko-made
case+LCD+misc set would serve you better with a GTA04 mobo inside,
and you don't see value in the GTA02 mobo, then please pass that old
mobo to someone else who would appreciate it enough to 3D-print a new
case for it or whatever, rather than waste it.

 BTW, one issue with Calypso is that as the proportion of non-3G phones in
 use decreases, coverage for non-3G phones is going down.  Maybe it's not
 yet a problem, but it's only a question of time.

Yes, that is a very major threat.  Fortunately it hasn't happened yet,
at least not in my part of the world.  I use a Calypso-based Pirelli
DP-L10 as my daily phone, I roam all over Southern California (from
Los Angeles to the Mexican border), and I have yet to encounter even
one spot with poor or no GSM coverage.  And that's despite this phone
(like all of my other GSM phones) supporting only the primary USA band
at 1900 MHz and not secondary band at 850 MHz!  (The latter is a
relatively new addition, a spectrum reallocation from AMPS which was
still in service as late as 2008, at least according to Wikipedia.)

But when the major commercial operators do shut down their GSM
services, we would have to set up our own, squatting on unused
frequencies like pirate radio broadcasters do...

The number I dialed in this test is the Automated Computer Time Service
provided by the National Institute of Standards and Technology:

Note how the above web page says, in part: Digital modems, such as
[...] wireless modems, cannot synchronize using ACTS.  Well, the log
above clearly shows that they are wrong, at least in the case of
high-quality wireless modems like Calypso. :-)

CSD calls may be placed from a GSM mobile either to a land line or to
another mobile.  (I don't know if it's possible to establish a CSD
connection from a land line to a mobile.)  When placing a CSD call to
a land line, one can connect to a traditional dial-up modem on the
receiving end - that's how I connected to ACTS, and if you've got your
own UNIX etc server at home with an old-fashioned modem on a land
line, it is really neat to be able to connect to it from anywhere in
the world via CSD, *bypassing the Internet*!

When you place a CSD call to another mobile, the network tells the
latter that it is a CSD call rather than voice.  If you have a GTA02,
you can have some fun by testing how various other mobile phones react
to incoming CSD calls: just have your FR dial a CSD call to the number
belonging to some standard cellphone (dumb or smart), running
standard proprietary fw, and see how the latter reacts to receiving
such an unusual call. :-)  To dial a CSD call, just omit the ending
';' from the ATD command you would normally use to dial an ordinary
voice call - see my log above.

But not all modems are created equal.  I've got a Huawei E303 3G modem
in the USB stick form factor to play with, and it appears that this
modem's fw does not support CSD at all.  After doing the usb_modeswitch
voodoo typically needed for these USB 3G modems (usually automated via
udev rules, but I had to install an updated usb_modeswitch package on
my Slackware 13.37 laptop), the modem shows up as a bunch of
/dev/ttyUSBx devices, supported by the option kernel module - hence
I wonder if it's anything like the modem in the GTA04.  /dev/ttyUSB0
presents an AT command interface, and the following observations can
be made from the latter:

* One can dial voice calls with ATDnumber; - makes the phone ring on
  the other end; upon answering that call one hears noise - the modem

 instead of modifying
 leaked firmware for a system that never has been locked?

Modifying leaked firmware is not an accurate description of what I
am doing.  As you should know full well, I am designing and building
my own Free Plain Phone, and I have chosen to use the same Calypso
chipset as used in the GTA02.  I chose this chipset because it already
exists, because it is known to work exceptionally well, at least in
dumbphone applications (I've been using one of my Pirelli phones as
my everyday cellphone since last spring, and I have nothing but praise
for it in terms of battery life, GSM signal strength and call quality),
because all hardware documentation and firmware sources for this
chipset have already been freed, and because I have already amassed a
great deal of experience working with this chipset.

Providing hacking support for Openmoko-made modems is simply a side-
product of my FreeCalypso work: I have chosen to bring my firmware up
on known-working hardware first, so that when I build my own hw and
get to debug it, I will have the benefit of known-working firmware.

Put another way, the free phone community (combination of FreeCalypso
and OsmocomBB projects) has already made great progress with the
Calypso chipset.  Switching to another vendor's chipset on a whim
would be an enormous setback for the project and for the community,
and it is not fair for you to ask that of us - here I am referring to
the you should be working on this instead of that argument in your

 So your claim of GTA02 is 100% freeable and GTA04 is not is only based on
 your disinterest to work on solutions?

I am working on solutions, but the problem I have chosen to solve is
different from yours.  Some people, such as me, simply want a good
working cellphone, a device for making and receiving phone calls on
the go - and we want this cellphone to be free as in 100% owned and
controlled by the user.  If the objective is to have a plain phone,
rather than a mobile computer, a device consisting of just one baseband
processor, without an extra application processor, is a technically
superior solution for the problem at hand: greater battery life, less
unnecessary complexity, fewer points of failure.  And the existence of
the Calypso chipset makes it possible for such a simple and efficient
dumbphone to also be 100% free by virtue of the user owning and
controlling the complete firmware.

Then there are those people who do want their pocket-resident device
to be a computer complete with an OS like GNU/Linux, rather than just
a phone - but some of those people would also want that device to be
100% free including the telephony processor - and not just half-free
aka half-pregnant.  For this class of users, the best currently
extant device is the GTA02, made by Openmoko - not your GTA04, and not
my dumbphone either.

Yes, there is the problem of these devices no longer being made - but
instead of solving this problem by building a new device that would be
as near-identical to the GTA02 as possible, including the Calypso
(just like how I seek to copy the Pirelli DP-L10 as closely to verbatim
as possible), you are making it worse by *actively destroying* the
remaining stock of Openmoko phones!

Hence we will likely always be fighting on opposite sides.

Aside from that, there are only two points in Nikolaus' last post
which I feel a need to respond to:

 And if you encrypt the whole communication path yourself, why do you care
 what the modem is doing?

Because there are many kinds of bugs which have nothing to do with
privacy/security issues - plain old bugs which cause the device to
simply not work under certain circumstances.  I have encountered more
than my share of such bugs in products of every kind, cellphones and
modems being no exception (although none in Om's firmware so far), and
I highly value the ability to diagnose and fix such bugs myself when
and if I get bitten by one.

 No. If you fight for freeing the Qualcomm modem you will satisfy both
 sides: Your 100% freedom and a device that can be produced as
 many as you need - and has higher data rates and a better processor.

Of course it would wonderful for all kinds of reasons to have a free
modem that can connect to UMTS networks in addition to GSM, and can
make use of mobile data services at EDGE or even 3G speeds rather than
just plain GPRS.

But given a choice between (a) continuing my current FreeCalypso work
and producing a 100% free GSM-only phone/modem in a foreseeable time
frame with 100% certainty or (b) abandoning this work and venturing
into the completely unknown territory of baseband chipsets from other
vendors, with nowhere near the guarantee of success in the near future
like we have with the Calypso, I feel that (a) is a much more sensible
choice for a developer in my position, and I suspect that at least
some people on this list would agree with me on this question.

/gsm/com/rfcap: tri-band GSM modem believes itself to be quad-band

2014-01-15 Thread Michael Spacefalcon
Hello Om community,

In the course of hacking TI GSM firmwares, I have come across something
that some of you may find interesting, or might even have some insight

We all know that our good familiar Neo Freerunner (GTA02) was made in
two versions: one with 900/1800/1900 MHz bands, the other with
850/1800/1900 MHz instead.  The hardware difference is one RF SAW
filter part populated differently on the same PCB; see this picture:

The SAW filters for the GSM downlink Rx path are the 3 little buggers
near the upper right corner, immediately adjacent to the shiny metallic
component which is the antenna switch.  There is one Rx SAW filter for
each of the 3 supported bands: one for 1800 MHz (both GTA02 versions),
one for 1900 MHz (ditto), and one populated for either 850 or 900 MHz.
(*I think* the topmost one out of the 3 in that picture is the one
responsible for the 850 vs. 900 MHz difference, but please double-check
that before attempting any surgery on your Neo!)

Well, here is the part which will surely surprise at least some of you:
the standard firmware for the GTA01/02 modem (which is the same for
all versions, both GTA01 and GTA02) does not actually know which 3
frequency bands are supported by the device it runs on!  And no, it
does not auto-detect either: there is no way (short of ESP) for any
firmware running on the Calypso/Iota/Rita chipset to divine what kind
of SAW filter sits between that chipset and the antenna.

Instead, as strange as it may sound, the modem (at least when running
the standard mokoN firmware, see below) believes itself to be quad-

In TI's universe, the standard way to teach a GSM device (phone or
modem) which GSM frequency bands it supports is *not* to hard-code
that knowledge in the firmware at compile time; instead this property
is stored in a configuration file named /gsm/com/rfcap in the GSM
device file system.  Yes, TI-based GSM devices all use a flash file
system with a very UNIX-like look and feel, including UNIX-style
pathnames; see my write-up:

Like most files in TI's GSM FFS, /gsm/com/rfcap is a binary file, not
ASCII.  It is a file of exactly 16 bytes, and although I haven't found
a formal document describing its format in plain English, we can study
the code that reads this file and acts upon its content:

The 16-byte file is being read into a variable of type EF_RFCAP, which
is defined here:

Lines 442 through 460 (inclusive) give the structure definition, which
is followed by the definitions for the bit fields in each byte.

And here is what this /gsm/com/rfcap file contains on a standard GTA02
modem, as revealed by a TIFFS parsing tool such as the mpffs-tools-r1
package I released last summer:

00 1F 41 14 00 00 00 00  50 00 00 A5 05 00 C0 00

Decoding the meaning of the rest of the bytes is left as an exercise
for the reader, but I draw your attention to the 2nd byte, which is 1F.
This byte indicates which RF bands are physically supported by the MS
(mobile station) hardware, and 1F means quad-band, i.e., all 4 of 850,
900, 1800 and 1900 MHz.  Thus even though my trusty GTA02 is only
900/1800/1900 MHz tri-band in reality, it believes itself to be

Digging some more, one finds that the 16 bytes quoted above appear in
the moko10 and moko11 fw images (convert them from *.m0 to plain binary
with the mokosrec2bin.c utility I wrote almost a year ago, then do the
binary grep with the memmem() C library function), and further
analysis reveals that these standard firmwares unconditionally
overwrite the /gsm/com/rfcap file in FFS with the hard-coded string
of bytes on every boot.  To convince yourself of the latter fact, take
a GTA02 modem with moko11 in it, change the rfcap file in FFS to
something else, reboot the modem normally, and observe that the rfcap
file will be reverted back to the 16 bytes shown above, claiming to be
a quad-band GSM device.

My leo2moko firmware does not contain this rfcap-resetting feature:
it does not automatically overwrite the rfcap file with anything, and
uses whatever settings happen to be written in the FFS (the modem's
flash file system).  At the present, there is no practical difference:
if your modem ever ran moko10 or moko11 prior to being flashed with
leo2moko, the content of the /gsm/com/rfcap file in FFS will be what
moko10/11 wrote into it the last time it booted, which is the hard-
coded I am quad-band value.

But I wonder - and this is really the main reason for this lengthy
post of mine - is it really a good idea for a tri-band GSM modem to
believe itself to be quad-band?  There are two potential problems I
can think of:

 Bottom line: even 850MHz FR can do 900MHz but the reception is pretty poor=
 though just sufficient in usual urban environment.

Hmm, interesting!  Of course given the geographical theater I operate
in, my interest would be in going the other way around.  The funny/sad
thing is, I do not currently have *any* GSM (or GSM+newstuff) device
which has proper support for the 850 MHz band (the secondary GSM
band in the lands I operate in) and which I can hack in any way at all:
sure, there are 3G+ smartphones all around me, and they all claim to be
quad-band when they go into GSM fallback mode, but of course they are
the typical Android etc crap, and I don't know how to hack them (if
that can be done at all), so I don't even know whether that SGS2 (as
an example) is connected to an 850 MHz network or a 1900 MHz one!

As to the hackable Calypso devices I have (one FR and a few Pirelli
DP-L10s), they are all 900/1800/1900 MHz, so to this day I don't even
know what GSM services might exist in the 850 MHz band around me...
I do use one of these devices as my everyday phone though (and the
non-Calypso Mot V66 I used previously was/is 900/1800/1900 MHz as
well), so basically all my cellphone-using life I've been using what
is effectively a 1900 MHz only device.  I roam over a pretty wide area
and have yet to encounter a spot without good coverage - and it is
kinda neat when I realize that I get all this great coverage despite
my phone supporting just GSM1900 and absolutely nothing else!
(Meaning nothing else relevant to my geographical area.)

But given what you just said, I am now tempted to try running cell_log
(from OsmocomBB) set to the [128,251] ARFCN range (corresponding to
the 850 MHz band), and see if it can pick anything up.  I'll try it
when I get some time to play.

 I don't think network/BTS can direct the mobile to another channel, it can
 only adveritse other channels but it's up to mobile to determine if that=20
 channel actually works in the particular situation

Indeed I think that the scenario I hypothesized in my original post is
very unlikely in reality, but as far as the network directing a mobile
to a channel, I was thinking along the lines of what happens in call
establishment, channel hopping etc - granted, I still have a lot of GSM
learning ahead of me as I set out to reintegrated that code from in the place of the binary libs in
leo2moko, but I was under the impression that whenever the BTS basically
tells a mobile let's continue this conversion on channel so-and-so,
that direction contains not only the new timeslot number, but also the
new ARFCN, and at least in theory the network is free to pick any ARFCN
which it serves and believes the mobile to support as well.

But of course I could be entirely off-base here, as I haven't really
learned that part of GSM yet.

 there may be other=20
 problems to receive 900MHz band than just a SAW filter, like local interfer=
 or whatever.

I see what you are saying: the scenario of a tri-band mobile device
advertising and believing itself to be quad-band (what Om modems do)
is indistinguishable from that of a genuinely quad-band device having
the 4th band rendered unusable by some unpredictable external factors
like local interference.  A valid point indeed.

The fact that, as you say, an FR made for 850 MHz could receive 900 MHz
and work so-so (limp along) does make for an argument in favor of
keeping the I am QB setting in that /gsm/com/rfcap file - if that
file were changed to reflect just the bands officially supported by
a given FR unit, it would not even attempt tuning its radio to the 4th

Has anyone else in the community ever used an FR successfully in the
wrong band?

 When the mobile can't use a certain frequency, the BTS will not
 force the mobile to that frequency.

OK, I need to learn some more about what happens in channel hopping
scenarios, and how (and by whom) the frequency channel is selected in
those cases.

Oh, and while we are on the subject of GSM frequency bands, I guess I
need to give everyone an update on my efforts to build my own quad-band
Calypso phone.  Right now that project is bogged down in mechanical
design issues which have nothing to do with the number of GSM bands or
even with the Calypso chipset.  What I really want is something as
nearly-identical as possible to the Pirelli DP-L10, and I won't feel
satisfied with anything less than that.

Back in 2013-11 I was in communication with some seller (German
apparently, but advertised on a Chinese site) who claimed to have
around 700 of those Pirellis for sale.  I wanted 100, and the price
would have been some 3-4 months worth of my spare budget.  But just as
I raised the money for the first partial order, the guy told me that
someone else bought all of those phones, they had no more left, and
whoever bought all 700 or however many they had, was not willing to
resell any of them

Wow, I went to bed after my last post, and when I got up this morning,
there had been a lively discussion between Norayr, Joerg and Nick!

As much as I would love to be proven wrong on this, I consider it
*very* unlikely that there is any functional defect in moko11 which
somehow gets magically fixed with my current leo2moko transitional
step.  There probably *are* bugs galore in TI's binary object libs
which contain the bulk of the GSM protocol stack, likely even buffer
overflow etc bugs which could be exploited by someone setting up a
rogue BTS and feeding control packets over the air containing things
which shouldn't happen - but if such bugs are present in moko11,
they are probably present in all versions of TI's TCS211 binary libs,
including the versions used in my current leo2moko port, hence we
don't have a fix for that malady yet.

The LoCosto source at does have the
GSM/GPRS protocol stack in full source form (aside from GPF, which
appears to have been distributed as binary libs even inside TI!), and
I do seek to replace our current blobs with this LoCosto version, but
before we can do that, I first need to go through the hellish process
of reintegrating all of the lower-level pieces (basically everything
under chipsetsw in the leo2moko source tree) into my Unix/gcc build
environment - and I'm just starting on that one, currently trying to
figure out why the RVT task is not emitting system time trace
messages every 20 s like it should...

In the meantime, the only gain which the community can get from my
leo2moko transitional step is the change from a black box to a glass
box: you can see all of the sources and binary objects from which I
have built my fw, the binary objects contain a good amount of symbolic
information making disassembly quite practical, and there is a map
file from the linker which shows what every byte in the final
flashable binary is for and what it corresponds to in the source.

Congrats, you have successfully navigated one part which I thought
would be very hard for most users.

Using the loadtools you've got installed on your FR now, you can do
another important step: make a backup copy of your modem FFS.

Step 1: run fc-loadtool like this (from inside the FR):

fc-loadtool -h gta02 /dev/ttySAC0

You should see a bunch of messages followed by a loadtool prompt.

Step 2: when you reach that prompt, enter this command:

flash dump2bin my-flashdump.bin

You should get a dump of your modem flash content in a file whose name
will be whatever you've entered as the last argument.  The file should
be 4 MiB long.  Transfer it from your FR to your PC and examine it
with your favourite hex viewer.  You should see the original fw image
(moko10 or moko11 or whatever you are running) in the first 2.25 MiB
or so, then blank flash (all FF bytes) until offset 0x38, then 7
sectors of 64 KiB each (0x7 bytes total) of FFS (flash file system),
then blank flash again for the last 64 KiB.

Verify that the content of the flash dump is as expected, and save it
securely - having this backup copy will keep your FR from becoming a
brick in the case that some subsequent operation will destroy the RF
calibration values in FFS.

 Then, I have tried to compile the firmware with supplied wine environment.
 Inspite of using nowhine, I saw a lot of fontconfig warnings .

I never got those on my system; the whines I get from my wine are the
ones you can see in my cheesy nowhine.c source.  You are more than
welcome to edit nowhine.c and make it suppress whatever whines _you_
get. :-)))

 Build fails, failed a couple of times, both by using nowhine or wine
 without wrappers.

 Because one windows utility, probably linker, fails

Yes, it is the linker indeed, which is bad news because one can't
build a firmware image without passing the linker step. :-(

 Error details

Not much I can do with these: I don't have source for TI's compiler
toolchain any more than you do, and I'm not a wine expert either.
See below regarding what system I use.


Looks as it should, except for the wine page fault error when running

 I wonder, if the problem is in my wine version or system setup.
 I have 32 bit wine running on x86_64 GNU/Linux, use it sometimes, and it
 worked fine before.

I use Slackware (a GNU/Linux distro for Luddites like me), all 32-bit
only, nothing x86_64 at all:

Linux darkstar #1 SMP Sun Jan 27 05:32:33 GMT 2013 i686 Intel(R)

hec@darkstar:~$ cat /etc/slackware-version
Slackware 13.37.0
hec@darkstar:~$ wine --version

 I am sure, it would be much easier to debug and understand the problem
 in case of using native Unix build environment.

Yeah, no kidding!  Firmware that can only be built with a proprietary
compiler which exists only as Weendoze binaries for which none of us
has any source is not really free - hence my chosen subject for this
whole thread: First small steps toward free GSM firmware, not Free
GSM fw is finally here.  What we have so far is indeed only the first
small steps, not a complete victory yet.

I am working on it, albeit at a snail's pace.  I've got an ex-TI person
helping me with my FreeCalypso project (when TI shut their Wireless
Terminal Business Unit down, a lot of people were out of a job - wasn't
fun for those people, but guess why my FTP site now sports 4 different
TI source leaks :), and with that person's help I was able to
understand the overall architecture of how the major pieces fit
together.  Now I have an arduous task in front of me: in order to
rebuild the firmware in a sane environment (using gcc and all that
good stuff), I have to reintegrate the fw architecture piece to piece.

The dependency graph isn't cleanly-vertical, so it is not a simple
matter of the higher layers sitting atop the lower ones - almost every
piece depends on almost every other in some way.  So I have to take
one low-level piece, temporarily remove whatever dependencies it likely
has on other pieces which I haven't got to yet, and get that piece
integrated in my gcc-built fw tree.  Then add the next piece in the
same manner, and at some point I'll get to re-enabling the things I
had to temporarily stub out to get the first pieces to compile and
link...  Not fun at all, but I don't see any other way.

 This is something I've quietly had an interest in for a year plus.

Yup, I remember you from 2011. :-)

 I'd like to suggest that it would be beneficial not only to have some hand
 holding for people that want to compile, but also sample binary for those of
 us that may not have easy access to necessary hardware and software.

Compiling the leo2moko version of the GSM fw from the semi-src does
not require any special software, let alone hardware: the hardware is
any regular PC, the software is your favourite GNU/Linux distribution
with working Wine.  Nothing more is needed: if you have a system with
working Wine, just unpack my tarballs and run the script.

However, having a prebuilt binary of the leo2moko GSM fw (to encourage
prospective testers from the shy-land) does sound like a good idea, so
I have just put one out:

Or was your reference to necessary hardware and software regarding
the flashing process, rather than compiling the gsm-fw.m0 image

Regarding the flashing process, I do agree that the current barrier to
entry is still a little too high and could use some lowering.  As
things stand right now, if you want to do your own flashing operations
on the GSM modem in your GTA02, the following skills/tools are

1. Whatever distro you are running on your FR, you need to know it
   inside out: you need to know how to ssh into your phone, how to
   kill gsmd or whatever process talks to the modem (and to ensure
   that it doesn't get restarted until you are done flashing your new
   fw and wish to test it live), and how to twiddle the power_on and
   download controls for the modem under /sys, as appropriate for
   whichever GTA02 kernel version you are running.

2a. You need to be able to cross-compile my fc-loadtool utility to run
on the application (Linux) processor of your GTA02, and do it in a
way that will be compatible with your distro from the previous
paragraph.  (I could send you my binary, built with some
CodeSourcery toolchain for my Buildroot AP environment, but I
doubt that one would be able to just plop it into SHR or QtMoko or
whatever, and have it just work.)


2b. You need to buy a T191 unlock cable that would plug into your
Neo's headset jack - in that case you would be able to run
fc-loadtool from your GNU/Linux PC, removing the need to build it
for running from inside the Neo.  But even with this magic cable,
you would still need to satisfy requirement 1 above: you still
need to ensure that there is no gsmd etc running, and you'll need
to twiddle the download and power_on modem sysfs nodes by sshing
into the phone.

I'm thinking that one possible way to lower this entry barrier would
be to produce and publish a bootable SD card image with the following

* A known environment, eliminating the whatever FR distro you happen
  to be running factor;

* Specifically designed for manual poking at the GSM modem - no gsmd
  and no normal functionality;

* Have the special Linux image come up with the headset jack serial
  channel enabled and with the device screen showing pressable buttons
  for Modem ON and Modem OFF - thus anyone using the headset jack
  serial cable method would have no remaining barriers;

* Have the image also come up with ssh access via USB enabled, and
  have fc-loadtool and some other tools already available inside -
  thus anyone using the sans-special-cable method would be able to ssh
  into the phone in a known way and run commands which can be given
  verbatim with no sophisticated preparations needed.

Producing a Linux image like the above won't be an overnight deal, but
it is something that I can work toward.

 I might have had some qualms about repercussions of using this software
 in Europe,

Why?  The radio transmissions from the illegally-free fw are strictly
identical to those produced by the original (presumably legal) mokoN
firmware, so how would anyone ever detect that you are using my
illegally-free fw?  The physical appearance of the device (as would be
seen by a cop pulling you over on a highway for driving too fast or
whatever) also does not change with illegal fw flashing, so if the
device looked like a legal cellphone originally, it will still look
the same...

 I'd be able and would love to test once this effort approaches some level
 of maturity.

Ahmm, asking for some level of maturity before one is willing to
even *test* a piece of software is rather dysfunctional.  How would
the sw *ever* reach any level of maturity without some people testing
it early on, reporting their experiences, sending bug reports etc?
Therefore, *someone* needs to be willing to act as an adventurous
alpha tester, trying out what exists currently.

I do concede though that the barrier to entry for prospective testers

Adding the info to the wiki would be a good idea indeed, but there

The README file in the loadtools package tells you how to run
fc-loadtool as well.

I will grant though, that my current instructions are written assuming
a highly technical user, and it would indeed be beneficial to have
another, more hand-holding version for more novice users.  What we
need for that is a community volunteer who would be both able and
willing to produce one.  I.e., we need a community volunteer who can
work with someone like me on one end (understand my instructions etc),
and also be in touch with more novice users on the other end.

Anyone wants to volunteer?  All you would need to do is to go through
the process of compiling and flashing my GSM firmware into your GTA02,
become comfortable with the process, and then document it for others
who would need more novice-friendly hand-holding.

If you or anyone else would like to give it a try, you can start by
downloading the 3 tarballs listed above and then attempting to follow
the steps in the README files inside.  Tell me where you get stuck,
and I'll help you navigate that step.  If you can go through the
process once, even if it requires a lot of hand-holding from me,
chances are good that you would then be able to document the process
for others at the less technical level.


P.S. If anyone manages to get as far as the loadtool prompt, please
give me a shout before you type any flash erase or flash program
commands - I would not want you to ruin your device by wiping out its
very hard-to-recover RF calibration data.  If you succeed in reaching
the loadtool prompt, stop there and ask for further assistance - I
will then tell you how to save those precious RF calibration values.

There is no possibility of damage until you reach that loadtool
prompt and type a flash erase or flash program command though, so
prior to reaching that point, there is nothing to worry about - please
play freely!

Just as an FYI - if you use the competing OsmocomBB software (which is

IMEI you like toward the GSM network is even easier: because OsmocomBB
doesn't know how to parse TI's FFS (flash file system) format and to
extract the IMEI (or the RF calibration values) from it, there is no
IMEI changing with OsmocomBB per se.  With OsmocomBB you *always*
have to enter your own IMEI manually in their CLI, and the software
has no psychic powers to tell whether or not the number you've entered
matches what's printed on the sticker inside the battery compartment.

So if all you are after is transmitting a false IMEI toward GSM
networks, a very easy way to do so has been available through
OsmocomBB for many years before my recent work.  Changing the IMEI in
FFS (where either the phone's original firmware or my illegally-free

(NOR in a Multi-Chip Package combined with SRAM).  Neither dfu-util
nor the AP (application processor) bootloader it is talking to knows
anything about that separate hardware block.

In order to reflash the GSM modem, one needs to establish communication
with Calypso's own boot ROM.  That can be done either from a running
Linux system on the phone's AP (i.e., from inside the phone) or
externally via a classic T191 unlock cable plugged into the headset
jack.  (The latter approach makes more sense for FreeCalypso
developers.)  Either way, one needs Linux software running on the
phone's AP in order to control the power to the modem and to enable
the headset jack serial channel if you wish to use the latter.

2013-10-18 Thread Michael Spacefalcon
For those following the FreeCalypso project, I have just put out a
packaged release of my GSM flash reading/writing etc tools:

Of course the source for these tools has been available all along in
my freecalypso-sw Hg repository on and in my snapshot
tarballs on the FTP site, but the release I've just put out includes a
prebuilt loadagent.srec image as well, so you can now compile and run
my fc-loadtool utility without having to build an ARM7 cross-compiler
toolchain first (to compile loadagent for the Calypso target).

My fc-loadtool is a free (source-enabled) replacement for TI's
proprietary FLUID tool documented on the now-classic Wiki page:

The *.m0 byte-reversed S-record format for GSM firmware images appears
to have been used in all of TI's builds, both Calypso and the later
LoCosto etc (see the find, for example),
so it is no surprise that the official mokoN images linked to from
the above wiki page use this format.  My leo2moko port, which builds
with TI's original toolchain under Wine, produces an image in the same
format as well.

My fc-loadtool can flash these *.m0 images as well as the more standard
S-record and binary formats; I don't know too much about the exact
capabilities of TI's FLUID as I never found a source for that one.

You can thus use either fc-loadtool or the original fluid.exe to flash
either an official mokoN image or an image you built yourself from my
leo2moko port, i.e., the compatibility matrix is complete.

By GTA0x I meant GTA01 and GTA02.  GolDeliCo' so-called GTA04 is
rather badly misnamed: GTA originally stood for GSM-TI-AGPS; thus a
device that does not use a GSM chipset from TI cannot be properly
called GTA0x.

It is also quite misleading that Nikolaus markets his product as an
upgrade to the good old Openmoko phones, as it is actually a
downgrade: it replaces a free-able GSM modem (i.e., one on which the
ability to run 100% free fw is within reach) with a non-freeable one,
i.e., one on which such freeing is totally out of reach.

And for the record, regarding the recent prolonged debate on this

I agree totally with Bob Ham.  However, I differ from Bob in that in
my view, the closed proprietary nature of Nikolaus' product is not
worth shedding any tears over because it is a useless product in the
first place.  The good old GTA02 from Openmoko is a MUCH better phone
than any GTA04.

 Also, did you test if data connection works?

Only CSD, not GPRS.  I.e., I have tested CSD and saw it working; as to
GPRS, I haven't tested it because I have not yet learned it well
enough, but I suspect that it works - please test it yourself and let

 I don't use phone calls,

There is no 3G on the real GTA0x, i.e., on GTA01/02.

 I am very interested if this can be flashed to gta-02 device,

I have it flashed into mine. :)

 (unfortunately I don't own gta-04).

Don't say unfortunately, you are very fortunate to have a much
better device, which are sadly no longer made, and even more sadly,
the leftover stock of Om-made ones is rapidly being destroyed by
people like Nikolaus who cannibalize these great phones for plastic
parts to make their inferior GTA04...

 Also, is there is a possibility to
 change IMEI during flashing?

Yes, you can change the IMEI quite easily to whatever you like, and in
fact the ability to do so is completely independent of which fw you
use: my current leo2moko port, the future full FreeCalypso fw, or even
the original factory fw from Om.

The modem has a total of 4 MiB of its own NOR flash, divided (hw-wise
inside the chip) into two banks: a 3 MiB bank at the lower addresses
and a 1 MiB bank at the higher addresses.  The lower-addressed 3 MiB
bank holds the fw image - that is what you erase and overwrite when
you reflash from moko10 to moko11 for example, or when you flash my
FreeCalypso firmware.  The higher-addressed 1 MiB bank (or more
precisely, 7 sectors of 64 KiB each within that bank) holds the modem's
FFS (flash file system) in a TI-invented format - one which I had
successfully reverse-engineered even before I found the source, I
should add.

Whatever you do, DO NOT DESTROY YOUR ORIGINAL MODEM FFS!  The original
GSM modem FFS from Om's factory contains RF calibration data, and if
you lose these calibration values, your precious GTA0x will become a
brick (at least GSM-wise) unless you can get that RF calibration
redone.  For an idea of what kind of special RF test equipment would
be needed to redo the RF calibration, see this document from TI:


Needless to say, redoing the RF calibration would be *very* expensive.

My fc-loadtool utility (which you will need to compile from source
from my freecalypso-sw Mercurial tree) allows one to read out the
content of a flash memory region and to save it into a file.  If you
are going to do any hacking at all on your GTA0x GSM modem, I recommend
that you make a dump of your FFS sectors (containing these precious RF
calibration values) and save that dump very securely, before you do
anything else.

The IMEI is stored in the same FFS as the RF calibration values, just
in a different part of the directory hierarchy: the IMEI lives in an
8-byte file named /pcm/IMEI; the RF calibration data live in a bunch
of files under /gsm/rf.  I have not yet written a utility to edit that
/pcm/IMEI file inside the FFS image in a user-friendly manner, so for
now you would need to use a hex editor - the IMEI is stored in a very
simple unobfuscated form in that /pcm/IMEI file.

 Sorry if my questions are a little bit off topic. Anyway I am very
 interested in free fw for my devices - OM gta-02 and n900.

See above regarding Om GTA02.  As to the N900 from Nokia, I doubt that
much freeing can be done with its BB5 modem: I don't know of any
leaked hw docs (let alone fw sources) for that modem, and I've heard
something about it having a crypto-signature-checking bootloader - we
are VERY fortunately to NOT have one of the latter in the Calypso!

(Calypso's on-die ROM bootloader is actually awesome - not only is it
 completely non-secure, but it is also completely unbrickable: no
 matter what state you get your flash into, one can *always* break

Hello Om community,

I am very pleased to announce that after many years of searching, I
have finally found a copy of TI's firmware deliverable package for
their Leonardo development board, i.e., for their Calypso/Iota/Rita
chipset reference platform.  It is the package which TI must have
given to all of their chipset customers including Nokia, Motorola,
Compal, FIC/Openmoko, LG, BenQ and many others, and which was used by
all of these companies as the starting point for making their unique
proprietary firmwares.  This Leonardo firmware source can be found

It is a source with some object blobs unfortunately (but that was
expected), but it is complete in that one can build a functional fw
image from the included sources and object libraries.  This original
code will NOT run on a GTA0x modem; it runs on the Leonardo board
instead.  If you are curious as to what the Leonardo board looks
like, you can see a picture of it on page 10 of this TI document:

However, I have known for a long time that Om's GSM modem is actually
very close to the Leonardo board in terms of how the Calypso/Iota/RF
chip interconnections are wired.  (I already knew this fact ~2y ago
when I first saw the doc/calypso-signals.txt file in the OsmocomBB git
tree - read that text file and judge for yourselves.)  The implication
from this hardware similarity is that it should be quite easy to take
firmware code that runs on the Leonardo board and port it to run on
the GTA0x modem instead.

I have just proven the above hypothesis by producing a leo2moko port,
i.e., a port from Leonardo to moko.  You can find the Wine-buildable
source here:

You can build that source under Wine (see instructions in the README
file inside the tarball) and produce an S-record image which you can
then flash into your GTA0x GSM modem with fc-loadtool - the latter is
my free replacement for TI's proprietary FLUID.

My own limited experiments indicate that this firmware is able to dial
voice calls (makes the other party's phone ring), receive voice calls
(I dial the number of the test SIM card in my GTA02 and see RING
messages appearing in the AT command channel), and even make CSD
(circuit-switched data) calls successfully - being the outlaw that I
am, I take great joy in playing with CSD (which I plan on using for
encrypted voice further down the road) and thereby showing my middle
finger to the NSA etc.  However, I have NOT fully tested the normal
voice call operation: I have only verified that the fw places and
answers these calls, but I haven't tested the actual voice audio.  The
latter omission exists because I have very poor understanding of the
Linux-based software that needs to run on the GTA0x AP, and on my test
GTA02 I run a very minimal buildroot environment on the AP.  I have
not yet figured out how to configure the AP-controlled audio system to
pass the voice path between the GSM modem and the physical earpiece
and mic, hence my current inability to test this voice path.

Therefore, I encourage other community members to play with this
firmware and see if it actually works end-to-end for voice calls.

 Your free phone idea appeals to me enormously, Michael.

Yay, one more supporter!

 However, can GSM really be a base for secure communication anyway?  

I see that after your post, the thread on the mailing list veered off
into a discussion of security.  But that diversion totally misses the
point: it isn't so much about secure communication as it is about the
Four Freedoms of software:

When it comes to the matters of free software philosophy, I am very
much like RMS.  I have a major problem with carrying a device in my
pocket containing firmware for which I lack the source - not because
it is a security threat, but because it's morally wrong.

The only difference between me and RMS/FSF is on the matter of
legalities.  While I define free software in terms of exactly the same
4 freedoms as the FSF, RMS and the conventional free sw camp add an
additional condition that these 4 freedoms be exercised legally -
whereas I add no such extra clause: whether it's legally free or
illegally free, it's still free software to me.

There also are some practical considerations that affect only feature
phones and not smartphones.  I have yet to encounter a phone UI design
that doesn't suck, and I hope that most people on this list will agree
with me that being able to customize the UI to one's preferences is an
essential freedom that a geeky, empowered phone user should have - and
I mean *really* customize the UI, not just twiddle menu settings, but
being able to study, modify or even totally rewrite the UI code.

Smartphones have a separate application processor to run the UI, so
you can indeed play with the UI on Linux to your heart's content while
keeping the modem as a black box.  But this approach does not work for
a feature phone where the UI and the modem are tightly integrated into
a single whole.  Exercising full freedom over the UI code in a feature
phone requires having a complete and rebuildable source for the
firmware suite as a whole.  (Having the GSM stack pieces as binary
objects to be linked with the UI source would work too, but then one
gets tied to a proprietary compiler toolchain, etc.  In any case we
already have full source for the GSM stack thanks to the TSM30 and
LoCosto leaks, so it's a solved problem now.)

Now look at the situation from the perspective of a user who does NOT
want his or her phone to be anything other than a plain phone.  For
such a user, a non-smart feature phone ought to be ideal, but if the
user also wants the freedom to fully own the UI design, s/he currently
has to pay for an otherwise completely unnecessary application
processor.  And when I say pay for, I'm *not* referring to the
purchase price of the device - I would gladly pay a lot more for my
ideal Free Dumb Phone than the most expensive GTA04 or Ubuntu Edge or
whatever.  Instead I mean pay for in terms of carrying extra weight,
extra power consumption, extra system complexity otherwise unneeded,
many additional points of failure, etc.

*That* is what I seek to rectify with my Free Dumb Phone project,
aside from the moral issue.  Freedom is a right that all phone users
should enjoy, not a privilege that's limited to just Linux smartphones
to the exclusion of non-smart feature phones.

 I've heard that the encryption used is really crappy, and while some 
 things like MITM forced reregistration to disable encryption and 
 ease surveillance could be countered by appropriate phone settings, 
 if the best encryption algorithm available can be cracked by a home 
 PC in a few days, you're still screwed.

The GSM encryption is a red herring - it makes absolutely no difference
whether it's there or not.  Imagine if the GSM encryption were perfect
and unbreakable - what would change?  Nothing.  The over-the-air
encryption is only between the mobile station and the network.  In a
public phone network, where you can dial the phone number of any
stranger and hear each other's voices if the other party answers,
encryption can't be end-to-end.  The network has to be able to decrypt
with one end's key and re-encrypt with a different key for the other
end, so the network itself has (and must have) access to the cleartext
form of your digitized voice.

If I am the world's most wanted criminal and enemy #1 of all major
governments, and they want to spy on my phone conversations, they
aren't going to bother with cracking GSM over-the-air encryption,
they'll just put in a lawful intercept at the switch.

The only way to render all lawful intercept mechanisms ineffective
is to use end-to-end encryption.  That won't work when calling
strangers, or calling the transit line to check bus/train schedules
etc, but it's a very feasible mechanism for private and secure
communication mechanism among family members, friends etc.

 Is there some documentation available, or a man page ?

No documentation has been written yet, because there is nothing to
document yet: all that's there is a FreeNucleus RTOS skeleton and some
host tools for pushing code images to the Calypso.  See my earlier
posts in this thread for my planned roadmap of adding meat to this

The FreeCalypso project is still in a very early stage - most projects
aren't even announced at all when they are this early in the development
process.  The only reason why I'm releasing this code at all is to
satisfy the moral requirement: on my planet it is a crime to have some
ware and not share it, no matter what the ware is.

If you want to play with the current code just for fun (there isn't
anything more that you would be able to do with it), you should be able
to at least compile it, and if you have one of the two supported phone
models (DP-L10 or GTA02), even run it and see the serial output from
the FreeNucleus demo app.  The steps are:

1. Build and install the arm-elf cross-compile toolchain.  Look in the
   toolchain directory and it should be obvious.

2. Using that toolchain, compile the target-utils part.  (Just run make
   in the target-utils subdir with the toolchain in your PATH.)
   You'll get the loadagent.srec image.

3. Compile loadtools - again, just run make in the corresponding
   directory.  These are host tools, so they need to run on whatever
   Unix/Linux machine you'll be using to push code to the Calypso.  If
   you are doing this with a Pirelli phone, FreeCalypso loadtools need
   to run on your PC/desktop/laptop.  If you are playing with a GTA02
   instead, you will need to either make a special cable to get to the
   Calypso via the headphone jack, or build loadtools to run on the
   GTA02 AP.

4. Once you've got loadtools, loadagent.srec and a compatible Calypso
   phone, you can actually try running this stuff.  If you have
   successfully passed steps 1 through 3, but are having difficulties
   with this step, ask and I'll help you.  If you are still struggling
   with one of the previous steps, work on that first.

A command like this (from a laptop with a Pirelli DP-L10 phone
connected and showing up as /dev/ttyUSB0):

fc-loadtool -h pirelli /dev/ttyUSB0

or like this (from the GTA02 AP, talking to the Calypso part of the
same phone):

fc-loadtool -h gta02 /dev/ttySAC0

should produce output that looks like this:

Sending beacons to /dev/ttyUSB0
Got beacon response, attempting download
p command successful, switching to 115200 baud
Sending image payload
[a long line of dots]Sending checksum
c command successful, sending b
b command successful: downloaded image should now be running!

Script command: w16 fb02 00A4
Script command: w16 fb06 00A4
Script command: w16 fffef006 0008

The 3 lines beginning with FreeCalypso loadagent running will be
printed by code running on the Calypso chip itself, which you would
have built in step 2.  Once you are at the loadtool prompt, you are
interacting with the host utility you would have built in step 3,
which is in turn communicating over a serial channel with loadagent.srec
running on the Calypso.  Loadtool has commands for things like peeking
and poking registers, dumping and programming flash, etc.  But right
now the only documentation is the source code.  Type exit, quit or ^D
when you are done - it'll reboot the Pirelli phone or power off the
GTA02 GSM modem.

5. The Nucleus-based skeleton for what is meant to become the main GSM
   firmware lives in the nuc-fw directory.  You can build it as soon as
   you've got the arm-elf toolchain from step 1.  Unlike loadagent,
   which is meant to remain universal for all Calypso phones (just
   like TI's FLUID), the main firmware obviously has to be configured
   for a specific target.  The snapshot you are looking at has the
   beginnings of the configuration mechanism, but the latter doesn't
   do anything yet.  For now all that's there is the Nucleus demo, and
   it happens to be the same for all phones, so just type make in the
   nuc-fw directory with the toolchain from step 1 in your PATH.
   You'll get ramImage.srec, which you can run on your Calypso phone
   with the fc-xram utility:

fc-xram -h pirelli /dev/ttyUSB0 ramImage.srec

If you are doing this with a Pirelli DP-L10, you should see the output
from the demo app pouring on your terminal when you run the above
command.  Type ^\ to kill the fc-xram process on your host, but to stop
the demo app running on the phone and make the phone usable again,
you'll have to pull the battery and put it back in.  (And then reset
the clock, as this phone doesn't have a separate RTC

Well, as you've asked the community as a whole, without restrictive
language to exclude any particular factions of the community (e.g.,
the illegal faction, which I'm heading), I'll take the liberty of
posting my answer.

I am in fact working on building a new phone - as in new physical hw.
However, the type of phone I'm seeking to build is quite different from
what Canonical tried to fund, and from what most of this community
seems to be interested in.  I personally will never be happy with a
smartphone *of any kind* as my everyday phone - instead the kind of
phone I want is the kind we all had in the 1990s - a plain or dumb
or feature phone.  And that is the type of phone I'm working on
building - a plain old-fashioned candybar phone without any smarts,
and no application processor to run Linux or any other smartphone OS -
only the traditional ARM7 baseband processor running traditional RTOS-
based GSM phone firmware.

But the plain/dumb/feature phone which I'm working on building will
have one key difference from the ones you can buy for $20 on ebay: it
will be 100% free as in freedom, in terms of both hardware and
firmware.  In the case of hardware it means publishing full,
*unredacted* schematics and PCB EDA files, and choosing only those
components for which full documentation is available.  As for the
firmware, yes, it will be an RTOS phone, no Linux or the like, no
application processor, but the full C source for that RTOS-based
firmware can still be published.  And because such a totally free
phone can never, ever, ever be produced legally, I am doing it as an
explicitly-illegal project, under the aegis of the international
community of outlaws, criminals and lawbreakers - i.e., my brothers
and sisters.

Of course a project of this magnitude won't happen overnight.  But I
handle it the same way I've handled all other projects which appear
totally insurmountable at first: I divide the problem into bite-sized
chunks, and work on the initial stages without worrying too much about
what difficulties may lie in the later stages - I'll deal with those
when the time comes.  The FreeCalypso phone project has the following
rough roadmap:

1. Build the FreeCalypso software/firmware first.  In May-June of this
   year I have found some new and exciting TI firmware source leaks
   (archived on my mini-Wikileaks at which will
   hopefully make it unnecessary for me to sacrifice my life in a
   gunfire exchange with the German or Russian police after kidnapping
   a moko-hoarder: these new leaks appear to be much closer to TI's
   mainline than the famous PurpleLabs TSM30 source, and I'm quite
   confident that by using these new leaks I can recreate something
   very close to what Om-Inc and its former employees/contractors have
   wrongfully withheld from Humanity - but in full source form.  (The
   LoCosto leak in particular, which I'm backporting from LoCosto to
   Calypso, has the GSM stack in full source form, unlike what Om-Inc
   purportedly got, and it appears to be from the same time frame as
   Om's version - much newer than the TSM30 one.)

I am working on this sw/fw part right now, using the Pirelli DP-L10
feature phone and the GTA02 GSM modem as my two bring-up/test
platforms.  In fact, the Pirelli phone fits me almost perfectly in
terms of hardware features, and I have thought long and hard about
just settling on it as my hw platform.  But there are a few problems
with this existing platform which have ultimately swayed me to my
current plan of biting the bullet and building my own phone hw instead:

a) No schematics could be found for this phone.  (The OsmocomBB folks
   are also hacking on Compal/Motorola phones for which there are full
   schematics, but their hardware features are insufficient for me: I
   would really miss the tri-band support, the loudspeaker and the USB
   charging capability.)  Schematics can be reconstructed by PCB reverse
   engineering given enough determination, but it would be hard to
   justify the effort given the other two problems:

b) This particular phone has a bunch of extra chips beyond the
   essential Calypso chipset, and for most of these extra chips no
   docs can be found.  While they support functionality which I can
   easily live without (camera and WiFi), their presence would
   tremendously complicate any attempt to reconstruct the full
   schematics, and may throw up issues when the time comes to implement
   thorough power management: how do we ensure that these undocumented
   and unsupported chips are fully powered down?

c) The biggest show-stopper of all: the supply of these phones on the
   surplus market appears to have been exhausted.  I've managed to grab
   a few before they disappeared, so I've got enough for my sw/fw

 But one day your GTA02 will stop working - it might fall on the floor or

Although it may be the only available replacement at the present
moment, it shouldn't remain that way for long.  We, the FreeCalypso
community (see below), need to make an effort to produce a new
GTA02-like phone, Calypso-based.

The first naive thought would be to contract with some pirate
manufacturing company to make verbatim unauthorized clones of the
GTA02, by reverse-engineering the GTA02 PCB and copying it verbatim,
layer for layer, trace for trace, via for via.  But it probably
wouldn't be the wisest choice in technical terms, even if all of the
components were still readily available (which they aren't) - the
GTA02 board includes some really stupid design choices which I would
want to get rid of if we're going to the trouble of building new
boards - the Glamo being first and foremost.

Because the single most important feature I seek to retain from the
GTA02 is the Calypso, we will probably still need to send a dead GTA02
PCB to a pirate manufacturing / reverse eng shop to recover the PCB
layout withheld by Closedmoko-Inc.  (We already have the schematics
for the Calypso block, TI's Leonardo reference design, but the
corresponding PCB layout is currently missing.)  As for the rest of
the GTA02 board, i.e., the AP realm, I would want to simplify it quite
a bit - take the Glamo, Wifi and BT out, connect the audio directly to
the Iota (Calypso's analog part) so that nothing on the AP side needs
to remain powered during a long voice call, and if the original
Samsung AP is no longer available (which is probably the case),
replace it with whatever other AP we can find that does the minimal
functionality we need using the least amount of battery power.

The Calypso chips themselves can still be obtained on the grey market.
And once that supply runs out, we'll need to send a Spetsnaz unit into
whatever TI facility has the old IC fabrication masks, seize those,
and take them to some Chinese fab to restart the production of those

 that's why it's important to support 
 GTA04 - either by donation or buying the device.

Not being Calypso-based, the GTA04 is a massive downgrade from the
GTA02, and can't really be seen as a replacement except a very feeble

Therefore, anyone who wishes his/her phone to be a *phone*, rather
than a PDA or whatever, who sees the GSM processor as the most
important part of the phone, rather than some unimportant modem, and
for whom the concept of a Free Phone means running fully source-enabled
firmware on the actual phone (GSM baseband) processor, should NOT waste
his/her money on a GTA04 downgrade, and should instead donate to the
FreeCalypso project - the latter will need to raise funds to pay for
the professional pirate-manuf reverse engineering of the GTA02 PCB, to
buy Calypso chips on the grey market, and to build the actual new
Calypso phones.

The firmware will be the user's choice of FreeCalypso or OsmocomBB.  I
choose the former, but others can use whatever they like.

 Maybe i am wrong but openmoko as company is for years dead and nobody of the 
 old admins is willing to spend much time on maintaining the infrastructure. I

I don't understand why the people here find this concept so difficult

They were on German soil, but they weren't living there, and they
most certainly did not obey any of the German laws that were legally
in effect at that time - instead they obeyed the orders of their
Soviet Army commanders.  Ditto with me and the countries I operate in.

Yes, that's exactly what I'm using as my starting point.

As far as hardware documentation goes, all of it is neatly gathered on
my FTP site: /pub/GSM/Calypso on ifctfvax.Harhan.ORG.  100% complete
as far as I can tell - haven't spotted any omissions yet.

But software documentation is a different story.  The TSM30 source
release is just bare code, no documentation whatsoever, excepting the
scattered comments in the *.[ch] files and build scripts themselves.

My common sense tells me that TI had most likely provided its customers
(handset manufacturers) with some hand-holding documentation on how to
work with their firmware - where to go to make product-specific UI,
hardware support, etc changes, how to flash the firmware, how to talk
to it - setting IMEI numbers, RF calibration, testing, etc.  If some
kindred soul would be willing to leak that documentation (e.g., put it
on a .onion and have some disposable account post a link
to it), it would be immensely helpful to the FreeCalypso project.  But
I won't sit and wait for it with bated breath - I'll just bite the
bullet and painstakingly study the code to recover that knowledge.  It
will take longer, but the project will still proceed.

 Did you checked this?

I'm the guy who sent that ware to, from where those
torrents were then made. :-)

I am pretty confident that I can rip out the TMS320DA250 ties from the
FreeTSM30 code base, and make it run on a Calypso-only phone.  I will
also *attempt* to recreate the changes you have make for the moko
version (custom AT commands, wake-up signaling, whatever else is there
that I'm unaware of), that is, recreate them independently while being
denied a peek at your version.  If I succeed in that part, great.  But
if not, I will just screw the GTA0x and find a Calypso-only phone to
use, with no AP and hence no need for the wake-up logic, etc.

Either way, I will have a working cellphone in my pocket, running my
FreeCalypso firmware - which is my goal.  But your refusal to share
the moko-specific modifications you have made to the firmware will
make it less likely that my firmware will be a functional drop-in
replacement for the old one, which obviously has a direct bearing on

The *only* part that isn't certain is whether or not that firmware
will be usable on GTA02 phones as a drop-in replacement for the old

2013-02-13 Thread Michael Spacefalcon
Hello ex-Openmoko community,

The purpose of this announcement is to let everyone interested know
that my effort to liberate the original, fully functional (non-OsmocomBB)
firmware for the Calypso GSM baseband (as found in Closedmoko GTA0[12]
smartphones and many simpler feature phones) has not been abandoned.

Lacking the source or even semi-source for the specific version of the
Calypso GSM firmware that was used by the Closedmoko company (FIC), I
am taking the alternate approach: starting from the already-liberated
version of the same Purplelabs GSM stack for a different Calypso phone
(TSM30, aka SPT2C platform), and seeking to back-port it to the
Leonardo (reference board for basic Calypso phone designs) and to the
GTA02 GSM modem.

Specifically, I have just made the first successful step on that long
journey: I have successfully recompiled the Calypso GSM firmware image
from HispaPhreak's source code release, and done so without resorting
to a Windows machine or VM - using Wine version 1.5.23 under Slackware
Linux version 13.37.  Of course it still targets TSM30 hardware, so
don't even think about flashing it into a GTA02, but it's just the
first step of an exciting journey ahead.  Previously I kept saying
that HispaPhreak's TSM30 release *seemed* to be the complete source
for the GSM stack running on the Calypso, but now we know that it
actually *is* complete - yay!

I am doing this work in a Mercurial source control repository, and of
course I share it freely with the world.  Until I get my new Solaris
ZFS-based server up, I have temporarily hosted the Hg repository here:

The README file at the top of the Hg source tree summarizes what has
been done before me, what I have done, and what I plan to do next.
The ultimate goal of this project is to back-port the code to run on
the GTA02 Calypso, producing a new GSM firmware image that comes as
close as possible to the original Closedmoko one, but is fully built
from source, no binary blobs.

Of course I am lucky to have a GTA02 unit, which has become a rare
privilege now that the stock has apparently been exhausted.  To those
who don't have a GTA02, desire one, but can't get one because of the
discontinued production and stock exhaustion: don't despair yet!

After we are done liberating the Purplelabs Calypso firmware and
getting it to run on Leonardo/GTA0x platforms (not SPT2C/TSM30), we
can then address the hardware shortage problem by building a new
Calypso-based phone motherboard - essentially do what Golden Delicious
did, but instead of going to that UMTS modem, keep the Calypso.  My
FTP site already has the complete schematics for the Leonardo board
(TI's reference design for a Calypso phone), the PCB layout of the
Calypso block can be recovered by sending a dead GTA02 board to a PCB
reverse engineering shop (think pirate manufacturers), and I have
some ideas as to how/where we may be able to obtain some Calypso chips
and related components.  But this is a topic for much much later -
let's get the firmware liberated first, using our existing GTA02s.
Just don't despair if you aren't one of the lucky GTA02 owners.

Just to be clear, I shall continue with my FreeCalypso project based
on HispaPhreak's release whether or not we ever get a leak of the
Closedmoko bits.  After all, the latter were mostly object code as
we've all been told (let me guess guys, your TI bits have files like,, etc, right?), whereas HispaPhreak's version is
100% full source.  It is unfortunate that the full source version
targets the wrong hw platform, and it will take some work to back-port
it to Leonardo/GTA0x, but the result (a full source fw version for the
GTA02) will certainly be worth it.  But if someone does leak the
semi-source for the moko version, it would probably help a lot
with guiding the back-porting effort, particularly when the time comes
to recreate the moko-specific logic of the AP and BP signaling each
other to wake up.

 Arguably those two paragraphs are already well satisfied by oFono.
 oFono probably now has the advantage in terms of maturity and
 deployment, is compilable by a standard C compiler, and has a recent
 version packaged in Debian.

FSO is compilable with a standard C compiler as well. Every tarball release
we did has been shipping C files.

 The following may sound pointlessly controversial, but I don't intend it
 that way; I think it may help the FSO developers to review and

 all, given that oFono exists and appears to have the development
 mindshare and advantages noted above?  Would your objectives be achieved
 more quickly or easily by switching to oFono and contributing any needed

Oh, FSO is so much more than oFono. If you want to compare, then compare oFono

I don't buy that - I don't buy the fairy-tale that each and every

refrained from sneaking a personal copy home with him.  That is a

that company had received from TI.

I know of at least two former Om-Inc employees who have demonstrated
detailed knowledge of what that deliverable contained - I take that as
evidence that they are the ones most likely to be holding on to
personal copies.  Not 100% proof, but enough evidence to hire some
professionals to do a kidnapping operation as soon as I can gather up
the funds to do that.  And if the people whom I suspect to be holding
personal copies of the TI-Om deliverables have deleted those personal
copies, well, too bad for them, as the hot soldering iron won't get
taken out of their rectums until a copy of the ware is in my hands.

So, to those reading this who are holding those personal copies: just
upload a copy anonymously to some warez site, announce it on this list
using an untraceable anonymous email account, and then you will no

thermorectal treatment.

 This sounds like shooting yourself in the foot. As soon as I would do that,
 I can't sell you a GT04 any more because I don't receive any more of these

 major afford to get an updated fw and make it flashable.

Certain individuals in the Om community are holding personal copies of
that firmware in semi-source form, or more precisely, in the form of
object modules with full symbolic information (names of functions,
global variables, etc) - not quite the same as full source, but pretty
close in terms of hackability.  Unfortunately the greedy bastards are
refusing to share, hence extracting the ware from them requires the
use of a soldering iron, inserted rectally.  If anyone is willing to
perform such an operation for the benefit of the community, I can
supply the names of the suspects and my best available information as
to their physical whereabouts.

Alternatively, there exists the TSM30 firmware source: it's a
different Calypso phone, and that code is full source and readily
available from and other sites.  Unfortunately the TSM30
hardware has been very heavily modified from the Leonardo* baseline
(whereas the GSM part of GTA02 is almost identical with Leonardo),
hence backporting the TSM30 source to run on a Leonardo-style Calypso
subsystem like GTA02 would take a lot more work than what we could do
if we had the real GTA02 version of the semi-source.  But the
backport of the TSM30 to Leonardo/GTA02 does not seem impossible, just
really difficult, and I am hoping to find the time some day to tackle
that project - in my view, it is an ethically superior approach than

[*] Leonardo is TI's reference design for the Calypso/Iota/Rita
chipset; liberated Leonardo board schematics and chip docs for all
components are on my public FTP site.

There is also a possibility that someone in the People's Republic of
China may have a copy of the same semi-source deliverable which FIC
got from TI (that exact same deliverable or a very very similar one
must have been given to *all* makers of Calypso-based feature phones),
but who would be more open to sharing than the Om bastards.  Any
comrades in the PRC reading this, you know whom to email.

 and how much less  
 hackable is the new gsm chip's fw?

Instead what I want is an everyday cellphone that does voice calls,
SMS and CSD, and does so using software and firmware for which I have
access to inspectable and recompilable source, be it legal or illegal.

I'm currently in the process of trying to acquire a TSM30: that may be
the right phone for me, given that my GTA02 is currently a paperweight
due to the lack of an army capable of invading Germany and prying the
Closedmoko fw semi-src from its hoarders.  I should be able to acquire
at least one TSM30, but I'm hoping to be able to find at least two:
since no TSM30 schematics are available (I don't know whether it's
because they've never been released in the first place, or if they are
available in some obscure location and those who know that location
are selfishly refusing to point me to it), I will probably have to
reconstruct them by taking an actual TSM30 PCBA and sending it to a
professional PCB/PCBA reverse engineering lab where they would remove
all components, separate and image the layers of the PCB or whatever
they do to reconstruct the netlist and the layout of inner layers.
Unfortunately that process requires destroying at least one PCBA. :-(

Of course hiring a professional PCB/PCBA reverse eng lab is devilishly
expensive, but it should still be less expensive than hiring the kind
of people who could help me recover the semi-src I'm looking for by
some brute-force means...  Not to mention the cost of restructuring my
life to avoid ever visiting any country that does extradition...

What would I do if someone was willing to release an anonymous copy of
the GTA0x (or Leonardo baseline) Calypso fw semi-src, so that instead
of expending 100% of my life-force to recover that jewel I could
actually do something productive?  Well, in that case I would start by
taking my GTA02 out of the box in which it came, and putting my own
very simple distro on the Samsung application processor.  I would then
bring up the Calypso, using the knowledge of its code to understand
the process better.  Maybe even find and fix a bug or two in that
Calypso fw in the process.

After bringing up my own distro on the GTA02 that uses built-from-src
code for both the AP and the BP, I would quite seriously consider
building my own replacement PCBA just like Dr. HNS did.  If he and his
team could do it, why can't I?  Expect that my hw design goals and
target audience would be quite different.  I would keep the Calypso,
no UMTS, but possibly make it quad-band, copying the quad-band GSM RF
front-end from the Leonardo+ schematics - if I can find a place to get
that little passive component.  While I have no problem with the
Samsung AP on the GTA02, I realize that the component is most likely
unobtainable.  But since I would be targeting a user base for which
the part that really matters is the BP rather than the AP, I don't
really care which AP to use.  Perhaps I would borrow the OMAP AP from
the GTA04, or maybe find some significantly cheaper really basic AP
that can do the absolutely minimal functions I expect from it.  And I
would most certainly omit the features/components/complexity that is
of no interest to me: WiFi, BT and the accelerometer/etc sensors.  The
result would be a device meant to be a *phone*, not something else.

But I'm not going to put any more serious thought into that project
until and unless I can obtain the source or semi-src for the Calypso
fw, i.e., either a GTA0x/Leonardo/other non-TSM30 version or some docs
for the TSM30 which would make that already-available source version a
more viable starting point.

 I am not saying that everyone should upgrade. I would personally wait a bit 
 until i knew that the power management in GTA04 will be working - without
 that the it's not much usable as phone (i.e. charging twice a day is not
 comfortabe and will kill your battery soon). But it's up to anyone to
 collect objective information and decide.

PM issues are one of the major reasons why the absence of src/semi-src
for the Calypso fw is making my GTA02 serve as a paperweight.  From
what I understand, the engineers at Openmoko-Inc took the Leonardo
baseline code and made their own adaptations to it.  One of the latter
was the addition of the GPIO signal by way of which the BP wakes up
the AP on certain conditions - an incoming call being the prime
example, one would hope.  I've heard that they

Well, I've already got mine. :-)

But seriously, swapping PCBAs between GTA02 and GTA04 is a zero-sum
game.  The number of existing {case + LCM + GSM antenna + other bits}
sets is finite, and it stays the same whether you leave the original
GTA02 PCBAs in those cases or replace them with GTA04s.

And if someone solves the problem of existing case shortage by making
a new case and starts selling full GTA04s with cases, perhaps I'll
make my own Calypso-based PCBA to stuff into those new cases.  I've
been thinking about using Leonardo+ schematics (quad-band Calypso
reference board) as my starting point, including the quad-band GSM RF
front-end, and slapping some simple application processor in front of
it, whatever is most readily available.  Maybe even the same OMAP
which Dr. HNS has used in the GTA04 - I don't really care what the AP
is as long as it can run Linux with full source, but I want the GSM
part to be Calypso, because it's the best-understood cellular baseband
chipset from the hacking standpoint.

This photo is pretty good - thanks!  From it we can tell that:

* The RF transceiver chip is TRF6151C, just like the one on the
  Leonardo board for which we have the docs.  It's a *quad-band* GSM
  RF transceiver chip, although it isn't obvious from the pinout: it
  has 3 differential-pair RF inputs, but one of them (the one called
  GSM in the datasheet) handles both 900 and 850 MHz Rx.  (1800 MHz Rx
  is on the DCS input pair and 1900 MHz Rx is on the PCS one.)  The RF
  outputs going to the PA are single-ended and combined: one for the
  low bands, one for the high bands.

* The RF PA (power amplifier) is the classic RF3166, once again the
  same as what one would find in a vanilla Calypso phone.  The
  Leonardo board schematics feature AWT6108, but also say: Second
  source option is RF3133 from RF Micro Devices that can be used on
  same footprint.

* The shiny block component (corresponding to U401 in Om's component
  placement PDF doc) must be the antenna switch.  One can also see 3
  little components next to it, corresponding to U402 through U404.  I
  reason that these must be the SAW filters for the 3 bands supported
  by each GTA02 version.  It's too bad that Om-Inc chose not to use a
  part like M034F instead (an antenna switch version with the SAW
  filters built in), as that would have made it a quad-band phone: all
  other components are already quad-band-ready.

I wonder if the only difference between the 850/1800/1900 MHz and
900/1800/1900 MHz versions of the GTA02 is in that one SAW filter part
that sits between the low-band output pins of the antenna switch and
the low-band input pins of the TRF6151C.  (What makes me think so?
See how real quad-band phones based on the same Calypso chipset handle
it: Leonardo_plus_quadband_schem.pdf and the M034F.pdf in my PDF
Calypso doc collection.)

Makes me wonder if a GTA02 can be changed from one version to the
other by carefully replacing that one part and changing the Calypso FW
image accordingly...

Now we need to figure out what the RF block looks like in the TSM30:
that would tell us whether or not the RF chip control code is something
we would need to be concerned with when porting the TSM30 source to
the GTA02.  What we *really* need are TSM30 schematics.  Schematics
used to be included in phone service manuals, but I don't know how to
search for a service manual in Spanish...

Re: Sharing TSM30 source

2011-11-22 Thread Michael Sokolov
Hello Openmoko community,

I am happy to announce that the archivists at have added
my contribution of the TSM30 source to their website collection:

The content inside is exactly the same as what I have, they have
merely repackaged it from ISO to 7z format to make it more compact.

The actual TSM30 firmware source (for both processors, i.e., both the
Calypso and the TSM30's unknown other processor) is fully contained in
the file inside the 7z.  The rest is the Windows
development environment with which one can actually recompile the
beastie.  Unfortunately the latter is *not* simply ARM gcc/binutils
under Cygwin, it appears to be some proprietary compiler toolchain
native to the Windows culture.  The build process is driven by DOS
*.bat files, which then invoke some Windows version of make.  The
makefiles for the latter (usually of the *.mak form, DOS/Win-style)
are mostly autogenerated from some IDE rather than human-written, and
can be quite difficult to human-parse in some places.

I haven't actually tested if that Windows dev env can fully recompile
the source into flashable fw images.  No Windows machines here, and no
time to mess with wine or virtual machines or whatever.  And even if
it does successfully rebuild an fw image for the TSM30, what are we
going to do with it?  We want something that can run on GTA02 hw, not
TSM30 hw, or at least I do...

Making that TSM30 code truly useful would practically require porting
it from TSM30 hw to some more reasonable Calypso phone platform, such
as GTA02 or one of those really basic Calypso phones that OsmocomBB
folks are hacking on, and converting the build process to the standard
free software way while at it.  However, that is much easier said than

Given that this TSM30 src has originally been leaked and publicly
posted back in 2004 (I assume that's well before Om) and has been on
various mirror sites for years before various FUD forces had reduced
it to a hard-to-find status, I assume that many people, including some
here, have had copies of it, had been familiar with it and had studied
the code extensively (out of sheer curiosity if nothing else) for
quite some time, much longer than I have.

Now that the booty is once again publicly available from a well-
publicized location that is resistant to non-court-order-backed
FUD-style takedown requests and we can discuss it in an open manner,
perhaps someone who has been looking at this code for far longer than
I have can post some comments regarding its overall architecture, some
knowledge that would be helpful to those who might want to attempt
porting it from TSM30 to GTA02?

 I think you will find that it is imposible to make data calls to an
 analoge modem. The reason is that GSM and it's sucessor standards are
 inherently digital, and are derived from ISDN telephone standards, so
 nothing in your phone or in the phone network will create tones that
 will be understood by an analogue modem.

There is a gateway somewhere in the network, probably at the point
where the mobile network connects to the old PSTN, that does the
trick.  Just like for voice calls some gateway has to convert between
the 9600 bps or whatever codec is used in GSM and the classic 64 kbps
of the wireline world, that gateway is apparently also capable of
acting as a voiceband modem emulator, handling a data call on the GSM
side and doing V.32 or whatever modem tones on the wireline side.

I have personally used this feature back in 2004-2005 timeframe.  I
had a Mot V66 phone on T-Mobile USA, just like I do now, and I was
able to connect the data cable to my phone, run minicom or similar on
the laptop, and type ATDnumber, where the number was that of a land
line with a USR Courier V.everything modem.  It worked, connected at
9600 bps.

I want to do the same thing again.  Hopefully whatever gateway makes
it work hasn't been dismantled, although I will likely be its sole

 Given your other requirements for off the shelf hardware, I think your
 simplest solution would be to buy a mobile phone with a data port, and
 learn how to use that port as a GSM modem. For example I used to work
 for Nokia, and I know that with their phones, if you put them into PC
 Suite mode they will respond to AT commands on their serial/usb ports
 and let you do dial up internet to your ISP, or any other phone number.
 You may find that your current phone does what you need.

Yes, that's exactly what I used to do, using an identical phone.  But
it's a very clumsy solution, the data cable is bulky and inconvenient,
and the Mot V66 makes it impossible to connect the data port and
external power at the same time.

I was wondering if I could take one of those cell modem USB sticks
that a lot of people use nowadays for Internet on the road, and talk
AT commands to it.  Then I could try doing the ATDnumber from it: if
it works, it would be a lot more convenient than using a phone and a
data cable.

The data-only cell modem devices in the USB stick form factor have the
additional advantage of being completely batteryless, taking power
from the laptop's USB port and nowhere else.  It's a little easier for
me to tolerate using a device whose GSM firmware I have no source for
if that device is incapable of having any of its circuitry powered up
except during those brief moments when I plug it in.

 Now we have access to full documentation for TI Calypso and SMedia Glamo 

Ahh, so I assume you have found them under /pub/GSM on the
ifctfvax.Harhan.ORG FTP server. :-)

Note about the Calypso docs: while they are quite a bit more extensive
than the two famous PDFs linked to from Openmoko wiki pages (the
Leonardo board schematics really help one understand how the various
pieces of the TI chipset fit together, and Calypso is only one chip
out of that chipset), they still aren't 100% complete.  Here are the
missing parts I'm aware of:

* There exist several different versions of the Calypso DBB (digital
  baseband) chip.  I'm not sure if the docs I have are sufficient for
  navigating the differences between Calypso chip versions in various
  existing phones (see OsmocomBB).

* The analog baseband (ABB, codenamed Iota) also exists in several
  versions, all of which appear to be compatible with the Calypso DBB.
  The only one for which I've found documentation is the TWL3014, aka
  the original Iota.  (Iota's predecessor was apparently called
  Nausica, mentioned in passing in some Calypso docs.)  However, as
  one can see from the board photos in the Om wiki, the GTA02 phone
  features TWL3025 instead of TWL3014.  I don't know what the
  difference between these two chips is, and I don't know if the Iota
  codename applies only to TWL3014 or also to TWL3025.

* In addition to the DBB and the ABB, a working phone includes 3 RF

  - an active RF chip (RF xcvr) that's part of the TI chipset;
  - an RF PA (power amplifier), also active, but sourced from outside
of TI;
  - a passive RF chip (antenna switch and filters) that is also
sourced from outside of TI.

I have docs for the TRF6151C RF transceiver (Rita) and the M034F
passive RF front-end used on the quad-band Leonardo+ reference board.
But I don't know what RF components are used on the GTA02 (or GTA01
for that matter).  Reasoning from the fact that these phones aren't
quad-band, I figure that at least some of the RF components ought to
be different.  However, this photo from the Om wiki:

is not legible enough to make out what the RF components are.  (One
can see the TWL3025 ABB chip, and one can see *most* of the DBB chip
part number, but the suffix of the latter, possibly important, is
obscured by the metal shield structure.)  Yes, I realize that I can
take my GTA02 apart and look for myself, but the device is so delicate
and so expensive that I'm afraid of destroying the gem.

I hear that a number of GTA02s have been gutted to turn them into
GTA04s...  Perhaps someone can take one of those discarded GTA02
boards, remove all RF shields and snap some better photos?

I also have a hard time understanding why Openmoko Inc. didn't make
their phones quad-band GSM.  All components in the Calypso chipset,
including the classic Rita RF transceiver, support all 4 bands, and
the only extra thing one needs is a quad-band-capable passive RF
front-end chip.  Why couldn't they just use M034F like on the
Leonardo+ board or something equivalent?  We may never know...

 and GSM firmware is on the way. We have opportunity to study and fix it.

Another important clarification is in order here.  The GSM FW whose
source is in my possession, the one that's about to be sent to Cryptome
and which I'm equally eager to share with anyone else via either an
FTP upload or a CD-R by snail mail, is for the Vitelcom TSM30 phone,
*not* GTA02 or GTA01.  I don't have the GTA0x version, but some other
individuals right here on this mailing list do, and are *actively*
refusing to share - public shame on them!

(Note the emphasis on *actively* refusing.  There is a world of
 difference between having a mental handicap that stands in the way of
 learning modern file sharing techniques, but actively working around
 that handicap by offering to share via other means, however old-
 fashioned or unconventional they may be (my case with the TSM30
 source), versus tacitly acknowledging possession of a ware which
 others desperately need, yet quite deliberately refusing to share on
 ideological grounds: the case of Paul Fertser and the Closedmoko
 firmware semi-source.)

Porting the TSM30 version of the code to run on GTA02, replacing the
original Closedmoko firmware, would probably be the shortest path
toward the holy grail of making the GTA02 a fully free and functional
phone, i.e., it would probably be a shorter path than transforming
OsmocomBB into an end-user-usable firmware.  However, even this
shortest path appears to be a very steep mountain climb:

 You don't really need to host files on your personal FTP server, if you 
 don't need to keep access logs for let's say statistics purposes, of course.

My current ancient ftpd (the one that's part of 4.3BSD-Quasijarus
running on VAX hardware - yes, VAX) has no capability for recording
access logs at all.  But it also lacks support for restarting
interrupted downloads, hence hosting really large files over a flaky
Internet connection is a non-starter.  When I finally get around to
setting up a new server on beefier hardware (I really need about 5 TiB
to host my archive comfortably), I'll use a newer ftpd under Linux,
one that support the REST command.  The newer ftpd will probably also
come with logging ability, but I'll be sure to disable it.

Speaking of that: which ftpd would you recommend?  I would like one in
which it is easy to completely disable all logging, and have high
confidence that it's really disabled, i.e., that it isn't writing any
logs anywhere, period.

But the bottom line is: I have *lots* of goodies (close to 1 TiB right
now, the 5 TiB figure above is allowing room for growth) which I believe
belong in the public domain and which I would like to share with the
whole world.  Hosting the stuff on an FTP server is the only way that
my old-fart brain can understand.  I am too handicapped to learn the
more modern ways of doing it like torrents and whatnot.  My only
options are FTP and sending out CD/DVD copies via snail mail.

I have already made my offer of a *FREE* CD-R copy of my archive,
including the TSM30 stuff.  Free as in no need to reimburse me for the
negligible cost of media and postage.  Just get the CD-R copy from me
and then distribute it further in whichever way you see fit.  But if
you are voluntarily declining the CD-R copy I am offering at zero
cost, how is that any of my fault?

Just for the record, I've been offering these free CD-R copies of my
archive since 2007.  I haven't been counting, but the number of copies
I've sent out so far is probably in the upper double digits.  I have
probably sent out 3 or 4 since the TSM30 CD has been added to the set.

  internal antenna and all.

* No battery, drawing power from the laptop when in use, no possibility
  of any internal components being powered up when the stick is not
  inserted into a laptop's USB port.

* I want to buy this thing from someone who just sells equipment, not
  service.  I need this thing to take SIM cards, and I know I can get
  a SIM card from my local GSM/UMTS service provider without getting
  their equipment.

* I need something that is sufficiently well documented in terms of
  its external interface (AT commands?) so that I can drive it from,
  say, minicom.

* I need this device to be capable of placing old-fashioned data calls,
  not just Internet access.  By old-fashioned data calls I mean the
  arrangement where one dials a number from the mobile device with
  ATDnumber (no semicolon at the end, making it a data rather than
  voice call), and the number being dialed is a POTS land line with a
  plain old analog modem answering the call.  I want to be able to
  connect to my personal data center from remote locations bypassing
  the Internet.

* I need this device to support GSM/GPRS/EDGE fallback, not just UMTS.
  I would like to have UMTS capability, but only in addition to plain
  GSM/GPRS, not instead of.  I would also very much like to be able
  to switch between GSM and UMTS manually with AT commands, e.g., to
  force GSM/GPRS mode even when UMTS is available.

* I need this thing to support the 1900 MHz band when operating in the
  GSM/GPRS/EDGE fallback mode, so I can use it with T-Mobile USA.

So, would anyone here be able to recommend such a USB stick device for
me?  Maybe even with pointers to where I can buy one?

My original plan was to use my GTA02 for this purpose, but I'm not
currently able to do anything with that device because of the
community's discriminatory handling of the Calypso FW semi-source
code.  Let me clarify: while of course the ideal situation would be
for everyone in the world to have free access to the GSM fw source
code, I can grudgingly accept using consumer off-the-shelf hardware
for which *no one* in the supposed-open-source community has any
firmware source.  But I philosophically object to using a device for
which Paul Fertser has a copy of the AT interpreter source code while
I'm denied a copy of the same.

Not being able to use the GTA02, I'm still using my old Motorola V66
phone: it's a *very* dumb phone (well below what one would call a
feature phone) and it's full of misfeatures which I don't like (a UI
design that suits me very poorly, bad pre-USB connector for the charger
and data port interfaces, no ability to connect the data port and
external power at the same time, etc), but what makes it morally
acceptable is that I'm not aware of any supposed-open-source
developer(s) hoarding a copy of its firmware source, selectively
denying it to new entrants into the field.

With the Mot V66 poorly suited as a device for making data calls from
a Linux/x86 laptop and the GTA02 unusable altogether for moral /
philosophical reasons, I'm now looking into the possibility of getting
a separate data-only device in the USB stick form factor and keeping
it separate from my voice phone, as in a separate SIM card from my
service provider.  (I already have several lines on my account for my
large pseudofamily, no difficulty with adding one more.)

I'm not aware of any cellular data USB sticks with hackable GSM/UMTS/
whatever firmware, but I can grudgingly live with that because it
isn't the same as having a clique of supposed open source developers
exclusively hoarding the FW source.  From what I understand, the GTA04
developers were able to get docs for the external interface (AT
commands or whatever) to their UMTS modem without having to sign their
lives away in NDAs, right?

Oh, and before anyone accuses me of being a hypocrite and hoarding or
not-sharing the TSM30 FW source which I have finally located, let me
reiterate I *do* freely and readily share this source with everyone in
the world, just not via the Internet.  Not via the Internet because my
current FTP server doesn't have enough disk space and my external
Internet connection is too slow.  Instead I am offering a CD-R copy by
snail mail to anyone in the world who wants one.  Just give

 So, it's a dream to have a full GTA04 with case,battery,screen etc etc in a

When you gut your GTA02s to stuff GTA04 boards into them, PLEASE don't
throw the old GTA02 boards away, please save them as spares for people
like me!

Glamo chip docs found

Hello Openmoko community,

I've got some Glamo chip docs on my FTP site which I thought someone
here might find useful, given that this chip is used on the GTA02:

U-Boot source versions

2011-10-05 Thread Michael Sokolov
Sorry to bother y'all again with another stupid question...  I have
finally received my GTA02 hardware unit, and I'm starting to bring up
my software stack.  Starting with the bootloader.  I want to use U-Boot,
not Qi.  And I have two questions which I hope someone might be able to
help me with:

1. Which version/branch of U-Boot should I use?  I've tried looking at
   what's available on, found the u-boot.git tree, but
   there are several different branches in it, all appearing about
   equally recent, and all feature commit messages that look relevant
   to the GTA02.  Which is the good one to use?

2. How can I find the U-Boot source that *exactly* corresponds to what
   is already in the NOR flash from the factory?  It identifies itself
   as U-Boot 1.3.2-moko12 (May  9 2008 - 10:28:48).  I haven't been
   able to find a tag named moko12 in git, but maybe it's just my poor
   git skills.  U-Boot is GPL'ed...  Doesn't it require supplying the
   source that corresponds *exactly* to the binaries you ship?

Again, sorry to bother you all, but if someone can point me in the
right direction, it would help me a lot.

 I tried to fix few annoying bugs and using own u-boot version, you can

I think I have mis-expressed myself in my original post...  I am not
looking for a prebuilt binary, I want a source tree that I would then
compile myself.  That U-boot-gena2x wiki page contains a link to a
binary but no source - isn't that in violation of the GPL?

I would also prefer to stick to one of the branches in the u-boot.git
tree on, but my problem is that there are several to
choose from: I see good-looking branches named stable, zecke, andy,
mokopatches and willie.  What are the relative merits of these
branches?  *That* is the question I am looking for help with.
