Tinkerphones Stammtisch Pfalz

2016-08-12 Thread Dr. H. Nikolaus Schaller
Hi all,
there is a small group of us who think about having a "Stammisch Pfalz" in 
August, maybe on 20th.

Location is to be defined in the area between Pirmasens, Kaiserslautern, 
Landau, Grünstadt.

Please let us know if you are interested to attend so that we can better 
estimate
participation and think about a nice location.

BR,
Nikolaus

1st notice: Letux/GTA04 Kernel- and Userspace-Hacking weekend

2016-02-27 Thread Dr . H . Nikolaus Schaller
Hi all,
we (OpenPhoenux community Munich) are organizing a kernel- and user-space
hacking weekend to improve the Letux/GTA04 kernel and to make progress on
matching QtMoko with newer kernels and latest Debian.

This workshop is planned to have two groups:

a) Kernel - to work on the known (and new) issues [1], mainly power management,
but also others (e.g. Camera, Audio for GSM/FM/Bluetooth). The idea is to close
as many issues as possible.

b) QtMoko [2] - update the basis to Debian Jessie, make it compile,
add fixes so that we can use the latest kernels, make new packages.

The workshop location will be in Munich (Germany) area (details to be defined).
Date is also to be defined so that it fits for the participants, but the target 
is some
Saturday+Sunday in spring 2016.

We have a budget to support travel expenses.

Participation will be limited in the total number of people. I think a good 
group
size will be ca. 5 developers each. More is not productive and less is not 
enough
breadth of different experience.

If you think you can and want to participate and actively contribute, please 
apply
by a short mail to me, telling what you want to do and which expertise you have
and if you need support with travel expenses.

If you don't, but know somebody who could be interested and helpful, please
forward this e-mail.

Let's hope this helps to bring our community forward and fix some issues we
want to see solved for a long time.

BR and thanks,
Nikolaus

[ANN]: decided to start production for GTA04A5 boards

2015-07-30 Thread Dr. H. Nikolaus Schaller
Hi,
we finally decided to start the production of the GTA04A5 [1] boards and use 
the ~40 plastic cases we
have recently received to also build a batch of complete Letux 2804 [2] 
devices. And we have secured
a set of GTM601W modem modules.

Details will follow.

Thanks for your patience. Stay tuned. It will pay off!

Re: [Gta04-owner] OpenPhoenux and GTA04 at CCCamp?

2015-07-24 Thread Dr. H. Nikolaus Schaller
Hi,

Am 24.07.2015 um 18:53 schrieb Paul Kocialkowski cont...@paulk.fr:

 Next month, CCCamp will take place near Berlin, Germany.
 The event is a great occasion to highlight the GTA04 project and our
 OpenPhoenux community at large. Neo900 folks already plan on attending
 and will organize a Neo village:
 https://events.ccc.de/camp/2015/wiki/Village:Neo
 
 I will also attend to represent Replicant (and hopefully get a lightning
 talk about it, if not a self-organized session).

Good!

 In addition to
 presenting the project and the various freedom and
 privacy/security-related issues in mobile devices, I would also like to
 try and get new people to join-in.
 
 Nikolaus, do you plan on having some OpenPhoenux and GTA04
 representation at camp besides Neo900?

I didn’t know about this event until some weeks ago - and I personally
have a schedule conflict… And I am not a fan of outdoor camping either :)

 Also, my GTA04 still has a broken
 GPS connector, so I thought perhaps it would be the right time to see
 about it and get it fixed (Joerg already mentioned he would bring some
 soldering tools, too).

Yes, that would have been a good occasion. But you can also send it to me
(any time you like) and I can return it next day (sometimes same day). It
needs around 10 minutes to repair if the person knows how to do it quickly
and reliable.

 
 I would be very happy to meet members of the community there and talk
 about the future of Replicant on the OpenPhoenux projects and community!

Thanks for making us aware!

I am sure that some members of our community are going there. Maybe they
can share their plans and reply to this mail?

Nikolaus

Linux gta04 4.1.0-rc4-gta04+ #1096 SMP Tue May 19 13:58:31 CEST 2015 armv7l GNU/Linux

2015-05-19 Thread Dr. H. Nikolaus Schaller
We are proud to have this kernel available for testing [1].

What is new:
* we have fixed a NULL pointer issue in the bq27x00 driver which was introduced 
by 4.1-rc1
* we are preparing for DT support of the camera module; the OMAP3 ISP (Image 
Signal Processor) should already be configured correctly
* everything else that is new with 4.1 and comes to us without big efforts

Some things we are still working on:
* get the GPS chip power managed on open(“/dev/ttyO1”). Technically it works 
since 2 years, but we need to find a solution that is accepted by upstream 
maintainers.
* some tweaks to the touch screen driver are needed to make it more general 
(and useable for Replicant)
* camera
* twl4030 battery driver (fallback for devices like L3704 where hdq is n/a)
* general power management
* sound (we still need to implement voice hardware routing, and headset 
detection)

Please give it a try (it also runs on BeagleBoard/XM, BeagleBone Black or 
PandaBoard ES).

As usual, collaboration is welcome and/or donations [2] to support this work.

And please follow us on Twitter: https://twitter.com/goldelico

 Hi all,

 hole? Or

 No, nothing of that. Therefore, I think we owe you some short status update 
 on this project.
 
 There hasn’t been much to report in the last months, but now we have several 
 news
 within some days.
 
 1. I have checked again and we can still get the GTM601W, but the 
 distributor says
the risk is high that OPTION declares EOL any time and in that case we 
 would have
to make an order of at least 3000 units so that they restart production 
 just for us.
 
   This means we must secure these modules for us now, since there is no 
 replacement
   that easily fits into the space constraints of the GTA04 (resp. GTA01/02 
 board).
 
   Cinterion modules would be nice since they are planned for the Pyra and 
 the Neo900,
   but they are approx. 10% too big.
 
 2. we see some difficulties in getting the W2SG0084 GPS module, but that is 
 some
paperwork the distributor has to do with Wi2Wi.
 
   Nevertheless, this is also a risk candidate for EOL because only one 
 distributor shows
   stock.
 
 3. There are also good news:
we participate in the risk buy of Samsung 1GB RAM+512MB NAND chips (as
planned for the Neo900). So the GAT04A5 gets twice as much RAM :)
 
This chip has already been tested by reworking a BeagleBoard XM and 
 modifying
the boot loader (kernel didn’t find the NAND yet, but U-Boot did. This is 
 a problem
that will jointly be fixed with the Neo900 software team).
 
 4. Production: we still are a little away from the quorum of 100 preorders 
 (at the
moment of this writing we have estimated approx. half = 45 units). So it 
 is still
not possible to make final decisions about production dates and final 
 pricing.
 
So we need to get a little more support for our project. If you have 
 ideas, please
let us know or start activities. Many small activities are as good as a 
 big one!
And we know that this is a niche product that requires an existing 
 GTA01/02
device. So it is not possible to “attract the masses”. We must find and 
 convince
the previous GTA01/02 owners whose devices are collecting dust. There had 
 been
produced ca. 15k such devices so that we just need another 1/3% or in 
 other
words only 1 out of 300 GTA02 owners needs to decide for a GTA04A5.
 
 5. Regarding the risk buy of the GTM601W, RAM chips and W2SG0084, I plan to
take the budget (~5100 EUR) that we already have collected.
 
This will transform the vouchers into ownership of components. So it has 
 the
consequence that we can’t refund in money (cash, bank transfer) any more, 
 but
only in unused hardware components (i.e. 100 EUR ~ 1*GTM601+1*RAM+1*GPS)…
 
For future preorder vouchers you would also buy such a component set 
 (which we
would keep in safe warehouse of course) until we can really build the 
 whole devices.
 
 
 So quite some news and I would be happy if we can fill up the missing 
 preorders [1]
 sooner than later so that we can start production. Please think about 
 securing your
 set of components for the last production batch of the most open smartphone 
 platform
 that we already have.
 
 
 I have been thinking about ordering a GTA04A5, but there is one barrier.
 I need to be confident that it can draw less than 10mA in standby.

 Currently the best we have seen with GTA04A3,4 is about 20mA (and 40mA on
 Linux 4.0, but that must be a software issue).
 
 This is probably a software issue, but until it's actually been demonstrated
 that the hardware can sit in standby using under 10mA, I cannot be certain.

There will be = 2 changes that affect the standby current:
a) the 26 MHz oscillator is not always on any more
b) IrDA receiver and RS232 level shifters can be turned on/off separately (on 
A3/A4 either one is always on)
c) the HMC5883l and ITG3200 will likely be replaced by newer Bosch sensors

If you know something else which could affect standby current, please let me 
know.

Ah, a new unknown is the new SAMSUNG RAM/NAND chip. There we have no data sheet
but know that it is used in the N9.

 It’s all very frustrating...

At least for me it is fun and a playground to learn :)

Nikolaus

 My impression of the GTA04 marketing message is: the more people who
 buy, the cheaper the phone will be!  

 Unfortunately, it hasn't been
 very clear to me how much cheaper.  I suspect that the same is true
 for other people, particularly those who are not following the project
 as closely as I have.
 
 If I knew that the GTA04 could be produced for 300 Euro if say, 2000,
 were produced, that could help me convince other people.  Of course,
 if someone is willing to buy today, they might not be willing to wait
 a year.

Well, there is a rough indication 
http://shop.goldelico.com/wiki.php?page=GTA04A5

• the final price is expected to be (incl. 19% German VAT)
• 599 EUR if we reach 100 production units
• 549 EUR if we reach 200 production units
• 499 EUR if we reach 500 production units
   but we will try everything to get below this target! But
   EUR/USD exchange rate development is beyond our control

 
 One way around this is to use the strategy that kickstarter uses: only
 fund it if a threshold is reached.

We also have that. The threshold is 100 units preordered (where each
pre-order voucher at 100 EUR or above counts for one unit). This is equivalent
to a threshold of 1 EUR which could be used to secure some critical
components (e.g. 3G Modem, memory chips, WiFi module).

If we don’t reach this threshold before the 3G modem really becomes 
unobtainable,
the campaign ends unfunded. We just don’t have a fixed date for the campaign.

 Just a thought…

Any thought is always welcome!

 Hi Nikolaus,
 
 A couple of things made me decide to buy the ubuntu phone.

thanks!

 
 -1 The price. for me it is afordable at 170 euro vs +/- 600 euro for a
 neo900 and slightly less for the GTA04A5
 
 -2 The device is in mass production, compared to the volumes of GTA04
 or neo900

well, this is the simple henegg situation that we face for some years.

For our community products we have: because 1, there is no 2 and because 2 
there is no 1.

What makes the difference? Some investor (Ubuntu) did cover the risk of
buying the first set of thousands of eggs and was able to get the price down
(higher quantity buyer).

They can, because Ubuntu is not only a free (as in free beer) OS but Canonical
sells maintenance services (ubuntu advantage) to get the money to run
their operations.

This type of services is something our community lacks. And is even beyond the
openmoko approach (because it focusses on the client side while the money is
with servers, clouds and content).

 
 -3 Development is done by a huge team, with a long track record in
 development.

Well, the team here was big - but has become smaller and smaller.

I just wonder if they have a longer track record than the Openmoko
community.

Hm. Makes me think about:
* would people be interested in a real maintained Openmoko distribution
* combining everything we have (kernel, Replicant, QtMoko and other choices)
* not only for Openmoko devices but others as well to get a broader audience
* regularily maintained by fixed team
* those who spend let’s say 5 EUR / month get bug fixes and updates first


 -4 Using old components from the GTA02 to build a GTA04 will get me a
 new phone with and 8 year old screen, 8 year old battery, 8 year old
 case etc.

This is mostly a consequence of 1 and 2. A GTA05 could be much more
modern and made out of all-new components. But because of 1 and 2 there
is no GTA05.

 
 But i really appreciate what all members from the gta02 community have
 done in the past and are still doing today!
 
 Big thanks from me.
 Ed

Big thanks for sharing your thoughts.

Our key problem is that we don’t have a big budget to spend for a new GTA05
that can compete with others.

 I know, and also for me it's interesting a new engine for an old car, but you 
 will never exit from the 12 statement if new users will remain cut off from 
 the game, imho.
 
 your solution is directed only to a subset of older users and this can hardly 
 embrace a wide audience that allows to lower the final prices
 
 from my pov, you are cutting out both:
 - fresh users, potentially interested in getting a real open phone
 - old users, interested in getting an open phone competitive on price

It looks as if you are thinking along a “one solution fits everyone” strategy.

GTA04A5 is a solution for some group which is completely feasible, no dream, no 
vapourware.
It is a tested design and just needs to be financed to be produced.

Of course it does not make everybody happy.

But it does also not exclude to have something different (GTA05…) in the 
future. But it must be clear
that a GTA05 needs a lot of work, prefinancing of engineering and time (expect 
 1 year to develop
from scratch including injection moulds). So this also does not make everyone 
happy.

And it is much less lilkely to happen at all because it needs this prefinancing 
stuff…

Therefore we are not cutting out anyone - I am simply honest not to promise the
impossible (competitive price and new and immediately available). I prefer to 
say
what is possible and reachable. Like a low hanging fruit: GTA04A5.

 Thanks for the info.
 
 I did order the ubuntu phone and can't wait to test it out!

Interesting.

Makes me curious why you both spend money on that one instead of e.g. the 
GTA04A5?

Any answer is valid - and no need to be polite…

I am just curious to understand how people think and decide such things in

I have reveived some questions off-list where I would like to share the answers:

 Are you seriously considering to upgrade hardware? Very cool.

Yes, we constantly monitor what new interesting chips are coming that can be
integrated at low risk. Replacing the BMP085 (which by the way is no longer in
production) is just wiring up 8 pins to a different package.

And, we have to do that anyways since a handful of chips is no longer available
and *must* be replaced. I did give a presentation on OHSW about this topic.

But we have to be careful, since “big” changes (e.g. bigger display, quad-core 
CPU,
LTE) are not possible. They introduce too much risk that the whole board does 
not
work and some do not fit into the existing Openmoko plastic cases.
And they need too much work time to be integrated.

It is like mature software with an architecture designed some years ago that you
touch only if it is easy to touch and does not introduce regressions in 
unexpected
areas. I.e. changing the color or text of a button is ok, changing the menu 
structure
isn't :)

 Is there a recording of your OHSW talk?

 What about this 5000€ or 1€ target?


This target is not really comparable to a kickstarter limit. It is more thought 
as
an indicator to give a more imaginable (at least I hope) view on the project 
funding
status.

The real target we have is to get 100 preorders (vouchers) at 100 € each. This
is equivalent to a 1€ sum of preorders.

Only if we have reached that, we can seriously go to the production facility and
ask them to give us a quotation (it is some heavy unpaid work for them and I 
don’t
want to go to them just for fun). Only then, we know the real price of building
100 units.

We will then announce the price and ask to pay the difference between the 
voucher
and the final price. If nobody cancels his voucher, we can then start the 
production.

There is one aspect which could make us the 1€ a real goal.

I fear that we do not have much time left over to buy the OPTION GTM601W
3G modules. They are in production for quite a while, but there is no successor.

And as soon as OPTION is no longer able to buy some component inside the
module, they will stop production (maybe they already have stopped and we
don’t know yet). Then we only can buy what is still in some stock. Maybe at 
rising
price. Or we come too late and they say: sorry, we are sold out.

And the OPTION module is one of the deal-breaker components. If we can’t buy
it any more there is no chance to redesign the GTA04A5 board for a replacement
component. Other modules are thicker or bigger - and need a careful design-in
process.

So w/o GTM601 (or DM3730 or memory chip) there can be no GTA04A5. 

In that case, we simply refund the preorder vouchers.

So an option would be to use these vouchers to buy OPTION (pun unintended :)
GTM601W modules.

Then, in case of the project never succeeds, we would not refund the money,
but could send you the module in case the project fails to reach 100 units for
production.

This would transform the voucher for a GTA04A5 into a voucher for a GTM601W
module and a separate one for a GTA04A5 production run later.

But it is too early to really do that step since we just have 42. If we had 75, 
I would
say that we do this risk purchase.

 The campaign is already running for a while and running very slowly.
 Will it ever succeed? When will it considered to be failed?


Well, I don’t know since my crystal ball doesn’t tell that.

And yes, this funding campaign runs very slowly. Since it is a very special 
product
for a very special target group. Only GTA02 (and GTA01) owners have benefit
from it. And since we all are here on these lists, it does not make sense to 
start
a Kickstarter/IndieGoGo for the broad public to get more interested people. And,
there is no benefit of making it a competition against the calendar (4-8 weeks).

 What about case kits? I remember there was some effort to make it
 possible to replace old GTA02 parts with easier to obtain equivalents,
 so using GTA04 board in self-made case (like 3D printed one) would be
 possible. What's the situation right now?

To go into detail the situation is this:

In addition to the naked motherboard these parts from a GTA01/02 are reused:
a) case (3 black plastic parts plus white speaker box)
b) vibramotor
c) earpiece speaker
d) handsfree/music speaker(s)
e) display panel
f) battery
g) GSM antenna
h) active GPS antenna module

Replacements are
a) there are several STL designs available, even a wooden case looks feasible.
b) we will solder a small(er) vibramotor on the GTA04A5 board, so that it does 
not longer need to be reused.
c) here, we did have a replacement but it is now end of life. We have a 
supplier and catalog for other replacements.
d) they were easily available at Mouser until last summer. So we just have ~25 
pieces left over [1]. But it could be possible to find them on Alibaba.
e) here we have ca. 60 units [2] - and no idea if anyone has stock for more.
f) we still have some stock and maybe other of the well known Openmoko 
distributors as well.
g) here we want to offer a replacement (similar to the green “cucumber” in the 
photo [3]).
h) there are several GPS modules to choose from.

So in summary, we already offer some of the required components and will offer 
others.
But three key components (battery, handsfree speakers and display) are limited 
and w/o good replacments.

Nikolaus

ANN 1: gta04-kernel 3.19.0

2015-02-09 Thread Dr . H . Nikolaus Schaller
Hi,
we have upgraded the gta04-kernel to 3.19.0 which by itself does not change
much or fix significant issues, but we have achieved something we think is
awesome:

The kernel now also runs on the OMAP3530 based OpenPandora!

We did just develop and debug a new device tree. Not everything is working
yet, but it is now in a shape where we think we can announce it.

The really interesting fact will be that for the first time we have a common
kernel over several OMAP based open hardware projects: it supports the
GTA04 devices, the Beagle- and PandaBoard, the old OpenMoko-Beagle-Hybrid,
the OpenPandora and will also support the new OMAP5 Pyra handheld and
whatever might come in the future (GTA04A5?).

And as the really latest entry is the BeagleBone Black.

The same kernel binary. The same binary kernel modules, the same root file
system. Just loading a different device tree file and some small patches for
the root file system is sufficient. Even sharing a SD card is possible (within
some limitations). Something we are used to from the x86 world.
Just replace the motherboard, plug in the old hard disk and boot again.

And, we can mix this kernel with different root file systems: Debian,
Replicant, QtMoko (if we get it compiled…), QuantumSTEP (if we finish it
sometime), others to be defined.

So we are close to transforming “gta04” into a multiple-choice-distribution
for different hardware.

Here is a list of the features supported by this kernel on the different 
devices:

http://projects.goldelico.com/p/gta04-kernel/page/Platforms/

And, we are now at the forefront of the kernel development, since we
regularily merge with linus/master. By upstreaming our changes, we hope
that in some near future all these devices will be fully supported
directly by kernel.org.

So I hope that we are doing something you appreciate and find useful
and perhaps would like to support either through [1] or by testing, reporting
bugs and submitting patches.

We really appreciate your feedback, since we don’t find every bug and
flaw - and we always understand the bad and incomplete documentation [2]
we have written…

BR,
Nikolaus

maillist_openm...@aross.me:

 is the optional camera fully supported now? according to the manual it
 isn’t. so what is it now?

The status is that it is supported by the 3.12.7 kernel, but not optimized (the 
position of the image is shifted).
The newer kernels (3.18) do not yet support the camera since the OMAP3 Image 
Processor (ISP) does not have
Device Tree support yet and the camera module driver has not been adjusted to 
recent kernel API changes.

So if you want to help to get it work on 3.19-rc you are very welcome to the

2014-06-28 Thread Dr. H. Nikolaus Schaller
Hi,
there appears to be a new initiative which is taking all our values (openness, 
freedom, community development, ) and casting it into a new name:

http://indiephone.eu/faq/

The most common answer to that is that no other product is currently 
attempting to solve the problem as Indie Phone. That problem is how to empower 
mere mortals to own their own data. This is why we are crafting a beautiful 
experience that seamlessly combines hardware, software, and services, to create 
a consumer smartphone to compete with the likes of iPhone and Nexus.

e.g. compare to:

http://www.openphoenux.org

You are the owner:
• Be independent from big players.
• Make the system transparent, not the user.
• Keep control over your data.

Their claim that there is no other product appears to be completely ignoring 
all our efforts of the past years. And I am not aware of any relation with us.
They even copied to use the word indie/independent.

Does anyone know more about that?

I had in parallel contacted the indiephone.eu people and got an immediate 
answer that I think I should share, before the discussion is going wrong:

Is there any chance you can make it to the summit? (Where are you based?)

Would love to be involved and I’m sure there is a lot we can learn from you and 
perhaps we can bring some of you in to help us out with the hardware side of 
things. Our approach is very different in that we are focussed entirely on 
building independent consumer products that are design-led from the business 
model down (holistic design). That said, I believe we share the same goals 
independence and giving the user control/owndership. Our user happens to be 
consumers whereas the user for OpenPhoenux, as far as I can tell, is 
enthusiasts with technical knowledge.

We should definitely be talking and helping each other out.

If you can make it to Brighton next week — please try and come on the 3rd for 
our private social meet-up prior to the event as I’d love the opportunity to 
chat one-on-one :)

(And, although the schedule is tight, I believe we can squeeze in just one demo 
during the eat, drink, and watch session at lunch if you want 3 minutes to show 
off what you guys are working on.)

The summit mentioned appears to be this:

If anyone wants to and can go to Brighton next week, please let me know to

 Hi,
 
 I'd like to play with the compass but the info from the documentation page 
 does not correspond with what I got on my phone (using qtmoko v58). The page 
 I use is that one:
 http://projects.goldelico.com/p/gta04-kernel/page/Sensors/
 
 In the 'compass' section there is a switch to enable/disable sampling. On my 
 phone there is a directory 
 /sys/bus/i2c/devices/i2c-2/2-001e/
 but there is no 'rate' file in there. Same applies for the gyroscope.
 Has anything been changed?

No. The kenrel doc is for the Goldelico kernels which were 2.6.32 some years 
ago and now reflect the drivers of 3.12 (ff).

QtMoko AFAIK uses a 3.7 kernel and since the /sys node names are not stable 
(and never will be) you might have to do a little guesswork and look into the 
3.7 kernel source code to find out how the driver works.

Hope this helps,
Nikolaus

 That's your point of view. Point of view of a firmware hacker.

 But there are other points of view. E.g. some people expect the phone ring 
 when friends/wife/customer calls. I had many phones before and 2 phones after

Yes. This is one important factor. The other one was simply the economic hiccup 
end of 2008 why OM had to cancel the already developed GTA03 for simple 
economic reasons.

 
 Openmoko is different - they never provided SW for reliable phone. Openmoko 
 never provided stable maintainable kernel

This is completely different with the GTA04 and why I invite every remaining 
Openmoko GTA01/02 owner to cannibalize their device for a GTA04A5 motherboard. 
Because that goal is within reach with the GTA04.

We have not reached the goal to get the 100% complete and optimal kernel from 
kernel.org or debian.org, but are working on a 3.14 kernel and getting things 
mainline (already with some success). And Replicant 4.2 is starting to work as 
well.

BTW: more support for that work from the community would speed up progress.

  - instead they wasted their time on doing 4 ugly unusable distros while at 
 the time they had perfectly stable usable and working Qtopia.
  
 And even 5 years after there is no good kernel for Freerunner. 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 problem with resume.
  
 Now we have free firmware which is cool, but the usablity of the phone hasnt 
 changed much.

Except for QtMoko which IMHO also should get more support to optimize the last

 If freedom is not important to you, then you might as well use an

 I don't know, but isn't *that* something you should fight against
 instead of modifying

 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
 comment.
 
 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.

Agreed. The problem the GTA04 solves is that the GTA02 has no high-speed
modem. Has a  quite old CPU with scarce RAM and NAND. Has no sensors
for games. Has no camera option and some other gimmicks.

All this was expected to be solved by the GTA03 which never appeared
on the surface.

This is what I understand as an *upgrade*.

AFAIR it was never the claim of Openmoko to have an open modem firmware.
And Openmoko did never provide that (because of contractual obligations).

And having this was not formulated as an urgent problem of the Openmoko
community and did not stop to have ~20k units produced in total.

So we are not doing anything differently. We don't claim that the modem 
firmware is free and open. But the OS. So that you have 100% control over
what the modem does since you can verify that it is turned off if you command
it to be off.

  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.  

Even if you have a free and open firmware, it still has components that
are not free and open. Just for example the SIM card. And the network.
And the other end of your communication.

The speech sent by your 100% free phone is still decrypted at the BTS.
And if you encrypt the whole communication path yourself, why do you care
what the modem is doing?

 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

2014-01-16 Thread Dr. H. Nikolaus Schaller
Hi,
it is time to take a look onto the GTA04A5 campaign.

We have currently collected pledges for 19 units.

This is good, but not enough to start a new production run to reach a fairly 
reasonable final
price for those preorders.

The calculation is simple. The setup cost of a new production run for a GTA04 
type of
product is in the range of 4000€ .

This is cost that occurs before the first device is produced. It is for getting 
the PCB produced,
getting new stencils for solder pasting, and setting up the pickplace 
machines. It is so high
because the micro-via type of PCBs for 0.4mm BGAs is not a standard technology 
and setting
up the PickPlace machine is manual work depending on the number of components.

Usually it would even include the engineering cost for designing the new PCB, 
but I
do that for free (because it is fun and not difficult if you already have a 
GTA04A4 design done).
So this is my personal donation to the community...

So if we want to produce 20 units, each one must cover 200€ of these setup 
costs. In
addition to batch size dependent cost like chips (which also become cheaper if 
we buy
more of them), energy cost for running the pickplace machines etc.

I we reach a batch of 100 units, this one-time cost goes down to 40€ per unit. 
I.e. a saving
of 160€ per unit (and even more by component cost savings). Just by s/20/100/.

So please think again if you want to upgrade your GTA02 with a GTA04A5 board.

If you are looking for a Letux 2804 (GTA04 complete) and don't own a GTA02, we 
still
have a handful of used GTA02 devices with a GTA04A5-upgrade rebate.

And there have been some generous offers recently by community members for GTA02
devices that collect dust... They are also nice candidates for a GTA04A5 
upgrade.

Please note that the GTA02 is the only 5 years old smart phone where you can get
full support and even a motherboard upgrade. This is very unique and sort of 
modular
concept.


So how will be the future of the GTA04?

It will be further supported and we are working heavily to get as much of the 
kernel
modifications into mainline. The 3.12.7 kernel is available and working quite 
well.
And we are focussing on getting the device tree to support everything in 3.14.

As soon as this big construction site becomes a little more stable I hope that 
we can
better address the remaining power management aspects of OMAP3 again. Currently 
there
is so much change in certain subsystems that things change while you are 
analysing
and the results may no longer be valid after some kernel upgrade...

For 3D GPU support we are waiting that TI releases a new 3.12/13/14 compatible
SDK.

Improving Replicant 4 is also on our to-do list, but we could need some help.

QtMoko is something Radek should comment about, if he wants to upgrade the 
kernel.

2. have a GPIO monitor if the modem is turned on/off

Depends. The Neo900 is a new design based on experiences from the GTA04
project, and we try to share some components. But the Neo900 is planned to be
compatible to the Fremantle software which needs to add some hardware that
the GTA04 simply does not need (e.g. a second audio codec).

 
 Good luck, I will be watching with interest (and might put some money
 down).

Tnx,

 Is there any GTA04 board, which already has a W2SG0084i installed?

Yes, about 50 or 80 (I don't remember the exact figure) since the W2SG0004i
was EOL and could easily be swapped. Unfortunately we don't have a mapping
to serial numbers.

 If
 so, we could try to query/set the output rate according to chap. 5 NMEA

That one unfortunately only allows to specify the reporting rate in
multiples of 1 second, i.e. up to 255 seconds. But not 1/10 sec.

 Hi Nikolaus,
 
 glad to hear that, I'd be really happy to see a new device that might
 leave the exterior of the Neo's behind for something better.

No, the GTA04A5 will keep the Neo's exterior as it is.

It is still a motherboard replacement.

But as before you may be able to design your own case around it.

 A long time ago, people were interested in replacing the Calypso with
 a Telit modem for future devices; as you might think about a new
 platform, I wonder if the Telit modems might be considered, still?

Initially we tried with the Telit modems but they were not flat enough
and we would have had to sacrifice the speaker (handsfree).

Fortunately we found the GTM601 which is used in the GTA04A1-A4.

 The big difference to the Qualcomms is, that the user documentation is
 much better, including a freely available full AT command reference
 [2] and more.

They also have Qualcomm inside.

 They have, for example, the new L910 [1] with LTE
 support, and as they aren't used by most major phone makers, I'd
 assume that they might be more reasonable in delivering smaller,
 reasonably priced, batches.
 It also includes GNSS (GPS, GLONASS) support (with documented AT
 interface), and has VoLTE support (voice over LTE), which makes it
 reasonably future-proof.
 With an 28.2 * 28.2 * 2.2 mm (LGA 144) package it isn't exactly tiny,
 but not that much larger than alternatives I think.
 Their modules are all pin-compatible, so the NA and EU variants, as
 well as 2G, 3G, 4G variants can be replaced without further changes.

The same holds with the Cinterion PxS8 modules. Documentation is
also available w/o problems.

We are currently evaluating all these options, but there are technical
and commercial aspects to consider. E.g. the Telit xE910 modems
are 10% thicker and likely still too thick.

 An extra wish would be using a main SoC with ARM Mali graphics, so
 free GPU drivers would be realistic (in contrast to all other options
 it seems).
 I'd certainly be in.

There is no plan to change the CPU since the OMAP3/DM3730 is still
the best mobile processor that can easily be purchased in small
quantities. And (despite the GPU) it is very well documented and
supported by mainline linux.

So please don't expect a wonder to happen... Just small steps and
improvements.

Nikolaus

 Is there a similar possibility for the neo900?  If so, my answer would also 
 be no and yes.

The Neo900 has FM RX + TX (because the N900 has).

 
 I see that Silicon Labs has a chip that does FM and weather band (si4739), 
 but without transmit.  If there is no place to cram a tx antenna, maybe this 
 would be a good option.  It looks like they are almost pin compatible - I

 Thanks!
 
 One thing that has always bothered me a little bit is that the FM 
 transceiver
 is wired for digital IO rather than analog.  That means that the CPU needs 
 to
 be active to copy sound around in order to listen to the radio.  If the
 LOUT/ROUT pins were connected to the line-in pins on the audio chip you
 should be able to listen to the radio with the CPU off.
 
 Yes, that should be possible.
 
 It would mean that you couldn't get the same fidelity if you wanted a 
 digital
 copy of the broadcast, but I wonder if that really matters.
 
 What is the expected use-case of the FM radio?  If it is just for listening
 to, the current config doesn't seem to be optimal.
 
 Well, the TX direction is more interesting since it can play sound (incl. 
 navigation
 information) to a car radio. By using text2speech. And mix with sound.
 
 Connecting to the Audio in is a problem since we have already connected them
 to the headset jack. So that it is possible to record sound fed into the 
 headset
 jack. I.e. portable audio recorder...
 
 Is the portable audio recorder use case more valuable than the FM radio
 without excessive power usage use case?  I would be happy to sacrifice the
 stereo-aux-in if it meant I could listen to the radio for longer.
 
 For the price of another analogue switch like the one you use to isolate the
 headset outputs (U703) you could support both FM and AUX inputs.  Maybe that
 price is too high??

I will check. It is probably less a cost issue (such chips are around 50ct) but 
space
and (shielded) wiring. But since headset jack and the Si4721 are not far away
from each other it could work.

 
 
 And the FM-analog out are multiplexed with the digital interface on the 
 Si4721.
 So we would need some analog/digital switching circuits where we don't have
 space for :(
 
 I wouldn't suggest enabling both the analogue and digital interfaces.  Just
 the analogue.  Digital might be nice but isn't really necessary.

Well, it gives a better S/N since the signals are already A/D converted in the 
Si4721
and just need to be arecord file if you want to capture signals.

 
 
 
 Related: have you thought about connecting the bluetooth PCM interface
 directly to the TPS chip in the same way that the Modem's PCM interface is
 connected?
 
 That should allow the use of a bluetooth headset on a phone call without any
 CPU intervention.
 
 Yes, that could work to add these 2 wires (at least in the schematics - I 
 don't
 know if we can squeeze them into the PCB wire hairball). And I have checked
 that these two pins at the TPS65950 come up in GPIO (input) mode, i.e.
 don't interfere.
 
 One issue could be that there is no BSP clock for that interface on the TPS 
 side.
 I.e. it is shared with some other interface and I am not sure how to operate 
 it correctly.
 So we might have to wire up something else to really make it work.
 
 The clock for the bluetooth interface and the voice interface are shared.
 So the clock from the GSM module drives the whole chain from bluetooth
 through TWL4030 to GSM.

Well, we likely can't use the BT PCM to play music from memory? I put it on the 
checklist as well.

 
 
 Just thinking out loud - looking forward to the A5 being a reality!
 
 So I find both proposals really good, but I hesitate to add them... may need 
 a lot
 of work to add, and may finally not work. The problem with hardware is that
 we have to do it 100% right or risk scrapping a big set of PCBs or costly 
 rework
 in the production line. Unfortunately there is no apt-get upgrade or git 
 pull for
 the wires on a PCB...
 
 :-)  I'm waiting for the day when a 3D printer can print a fully populated
 multi-layer PCB (under voice command of course).

Me too. Incl. printing the wires and transistors on a Si chip :)

 
 Maybe in the spirit of openness a vote might be  instructive.
  Does anyone actually want stereo aux input through the 2.5mm jack?
  Does anyone actually want to listen to the FM radio without wasting power?
 
 (no and yes for me).

Free is a term only considering copyright. I.e. it is licenced under

But general usage of some hardware may be regulated by many other laws.
Customs, export, radio emissions, safety etc. Everything in life is more or less

 Afaik you can use it legally if you connect it directly to your own base

If you connect it by shielded cable or if you place both in a big shielded box.
I.e.  if the spurious emissions stay below some defined level and don't disturb
other services (which includes the public GSM network).

 Speaking in generalities - FPGAs use lots more power for a given task than 
 dedicated hardware.
 They are also a lot more expensive.
 This is unlikely to be $400K investment, then $20 per chip.
 More like 400K investment leading to something that works on a $1000 FPGA, 
 and uses several times the
 power of a comparable device.
 
 Is this interesting - in principle - yes - combined with an ARM licence, it 
 could lead to a moderately low risk CPU, if someone were willing to put up 
 the several-many million to make a CPU with it on die.
 
 Off-die GPUs are an utter non-starter for mobile devices.


Has anyone experience with the Zynq-7000? It has dual Cortex A9 with VFP/Neon - 
but apparently lacks a GPU...
Such a combination could be comparable with OMAP3/4 in computation power.

Maybe not the best one for a handheld mobile device, but for a tablet.

I agree with him. We don't owe the community anything beyond what we
have voluntarily done or will do.

In general the offer of Free projects is: look, here is something others have
piled up in the past years. If you want to use it, please use it. But you are
obliged to give back your changes to support the community.

You are argueing from an egocentric point of view: look, there is something,
others have piled up in the past years. I want to use it. So they are obliged
to give me everything I think I need (even if you don't really need it) to 
support
me or others.

At least this is what I read from rah's and your arguments.

 

 
 The request for clarification was probably not needed though, you have
 made it fairly clear over a few threads over the years that you aren't
 interested in making the gta04 Free Hardware as rah and myself
 appear to define it.

I simply don't believe in the Free Hardware ideology.

The reason is that there is the idea of an allmende or community
behind, where everyone gets back as much as he/she invests by
volunteer work. This is good - in theory.

With Free Hardware I simply don't see that being balanced. I.e. you
can't expect to get back enough high quality volunteer contributions
from the general public to balance what you have to invest yourself
to get something 100% done. And hardware must be finished 100%
at some deadline (contrary to community software projects - just send
out 3.12-rc4).

The GTA02-core project has clearly demonstrated that some years ago.
The engineering community development model does not work for
hardware. So there is no need for Free hardware licences to regulate
the interworking of a big worldwide engineering team.

Let's say it with some perspective: everybody should do what he/she
can do best. E.g. donate money so that experts can live from that and
invest their time to develop great hardware that allows to run as much
free software as possible (and is well enough documented for that
purpose - but not more). This does not need Free Hardware in your
definition.

 So end of discussion for me, I'll try to avoid replying to any further
 mails on the gta04 topic.

Yes, there is no need for discussions about the freedom of GTA04.

But technical discussions are always welcome.

 What immediately jumps to my mind is the small number of pins for the 
 modules, forcing everything to be based on serial interfaces.

Look at what MIPI.org has defined since 10 years. Display, Camera, Modem are 
all serial interfaces to use less wires. But nobody (not Apple or Samsung or 
HTC or Motogoogle or Micronokiasoft) has done a modular device.

 It's probably not realistic to be able to change a CPU module that way for 
 example.  Dicy for a camera module too.   But for tons of other I/O 
 applications, I think it's quite feasible.
 
 The guy behind this seems hesitant to bring it to Kickstarter. Maybe he's got 
 VC plans instead.  Maybe he has no plans... !

I would assume that his plan is to get publicity for his person. Not for the 
project.

Promise people infinite life or flying to the moon and they will follow...

I only agree that it is not Free Hardware.

And since it is obviously not closed hardware (like an iPhone, Lumia etc.)
it follows from logic that it must be open hardware.

 It was not open source.
  This issue has been discussed previously.  The
 source must be in the form customarily used for making modifications to
 it.  This is an important factor.

Why? I see the distinction between closed and open not in the convenience
of sharing information.

 
 From the GNU GPL 2:

 http://web.archive.org/web/20090305064954/http://www.sun.com/cddl/cddl.html

The common form of Schematics is a piece of paper with lines, circles and arcs.

 If a software company refused access to their software's source code in
 electronic text form and only released it in paper form (or in the form
 of a bitmap image inside a PDF), that software would not be considered
 open source.  The phrase that seems most appropriate for such
 software, I think, would be encumbered source.
 
 
 Wikipedia gives a fair description of open(/free) hardware:
 
  'Open-source hardware consists of physical artifacts of technology
  designed and offered by the open design movement.'
 https://en.wikipedia.org/wiki/Open_hardware
 
 And of the open design movement, it says this:
 
  'Open design is the development of physical products, machines and
  systems through use of publicly shared design information. ... The
  process is generally facilitated by the Internet and often performed
  without monetary compensation.

That is an description of the status quo and not a normative definition
of Open Hardware.

 The goals and philosophy are identical
  to that of the open-source movement, but are implemented for the
  development of physical products rather than software.'
 https://en.wikipedia.org/wiki/Open_design

Wikipedia is not a definition. It is a description of how authors see
the world.

 The Hardware Freedom Day website states the following:
 
  'Goals and philosophy of the Open Hardware movement are closely
  aligned with the ones of the Free Software movement.'
 http://www.hfday.org/open-hardware

They call themselves Freedom Day but try to coin the word Open Hardware.

I would be happy if they would talk about Free Hardware.

 
 The free hardware and open hardware communities derive their ethos from
 free software and open-source software.  Access to source files in the
 preferred format for making modifications is therefore an important
 requirement for free/open hardware just as it is for free/open software.

Again, what is the difference between Free and Open

 Your source code citations from licenses are nice, but license text is
 the right place where you should find definition of what's meant by term
 source code, OpenPhoenux page doesn't say that it's using terminilogy
 from ohanda or oshwa.

and not from GPL or BSD or MIT licenses etc.

We use CC and it defines:

Work means the literary and/or artistic work offered under the terms of this

I.e. paper is explicitly included and all forms of its expression.

 open hardware is imho closest term you can use to describe advantage
 of gta04 for other people asking why you don't use cheaper android phone
 or why they should buy gta04.

or even more closed buy an iPhone or Lumia...

 Using open-hardware-but-without-CAD-files is maybe less misleading for
 people who has great understanding of all free/open definitions used in
 the world (and wikipedia), but also more misleading for normal people.
 
 Your accusations sounds like if Nikolaus is using OHANDA clearly defined

 The source files are not public.  The only thing that is public is a PDF

Yes.

 I don't understand how you can maintain that the source files are

 You don't seem to understand that the difference in format is
 critical.  It is the difference that prevents the GTA04 being described
 as free hardware.

Yes, I don't really understand, because I don't care that much about sophistry
and ideology. I want to get things materialize.

And for me any printout that I can read is open source. A missing printout
is closed source. Tertium non datur.

 
 By your logic, all binary software executables are open because the
 format can be converted into assembler.  While it may be true that one
 can disassemble binaries and modify the resulting assembler, this is not
 what we're referring to by the phrase free software.

 
 Similarly, the GTA04 is not free hardware.
 
 
 And by the way, I looked into your idea of scanning PCB schematics.
 It's bogus.  I tried to see whether any suitable software was available
 but here's what I found instead:
 
  there is no direct way to translate pure graphical data to an
  intelligent schematic, EDA schematics contain a lot of intelligent
  information that simply is not available on a sheet of paper

  multitude of ways even a single IC could be represented. ... In short,
  it's unrealistic.

 Here I am referring to the typical discussion about binary blobs and

 You're obviously using the phrase free hardware to mean hardware that
 can run with entirely free software.  This seems to be non-normal usage.

 For example, see
 
  http://en.wikipedia.org/wiki/Hardware_Freedom_Day

Hm. That doesn't tell me much.

Neither the Openmoko, OpenPandora, Ubuntu Edge, GTA04 are
open hardware - and never were intended to be. They are
well documented hardware for free and open software.

Generally, I agree with jOERG's comments.

If you don't like this situation, start your own project and make it
open hardware (in your definition), but don't expect us to do that
step for you.

 Production problems show almost immediately, even if there is only one

 As you know, that has not been the experience with the GTA02, where
 audio quality output (works fine for line-out but not for headphones),
 GPS issues, and the 1024 issue have appeared over time and some of
 them took a long time to track down and fix.
 
 I can bet that your tests for GTA04 did not catch problems along the
 lines of power consumption issues that will only show up in particular
 usage scenarios that will only be used by the customer number 1462.

Yes, I agree that such tests can only be found by a field test (beta test or 
however
you like to call it).

But they are not production problems, but problems in the circuit design.
With production I mean making n identical copies of a piece of hardware.
And a production problem is if those are not really identical.

Compared with software, they are not compiler of kernel problems but
in the source code of some application.

Running field tests is a common practice in hardware development and
that is why some guys did loose their new iPhones before they were
announced in some bar... And even Apple did not find the antenna problems
before product launch.

So this type of bugs need a big community of persons really using a design.

 
 Also, if you can upgrade the screen and the CPU separately, you might
 attract a few other users, who aren't so interested in Freedom but do
 like the idea of customizing their phones.
 That is a dream that is not realistic. Every display has a different
 connector (there is no standardization!). And every CPU has different
 signals and power supply needs. I.e. you can swap an OMAP3505 for an
 OMAP3530 or an DM3730 but nor for an OMAP4 or OMAP5 or Snapdragon or
 i.MX6.  Because they are not designed for this way of use.
 
 I know.  But I'm not talking about swapping the actual CPU or the
 actual display.  I'm talking about swapping the CPU module or the
 display module.  I.e. create a standardized module interface around
 off-the-shelf (i.e. non-standardized) components.

Yes, there is even a standard for an interface between displays and CPU.
Well, even two or three:

MIPI, LVDS, HDMI/DVI.

 It would have its own cost (in money and in size), but in the long run,
 I hope the benefits of relying on standardized interfaces would make up
 for it.

MIPI is already doing all this:

http://www.mipi.org/specifications
http://mipi.org/about-mipi/mipi-interfaces-mobile-platform
http://en.wikipedia.org/wiki/Mobile_Industry_Processor_Interface

Everyone is there, ARM, TI, even Apple:

http://www.mipi.org/member-directory

But none of them is building modular devices. I wonder why.

 
 From what I can tell, Free Hardware projects don't benefit nearly enough
 from each other's efforts.  Not sure we have enough Sisyphus around to
 keep them all alive.

The problem for us is that we do not that easily get MIPI compliant
components or documents (for members only) than others. And we have
to use components that someone is willing to sell to us at a reasonable
price.

BTW: their monthly fees are public (different type of openness :):

 Production problems show almost immediately, even if there is only one

 In essence it goes to a modular approach - but modular typically drives
 cost up (at least for the version having the highest production numbers)
 and is in strong contradiction with miniaturization of handheld devices.
 
 In my part of the world, phones have been getting bigger rather than
 smaller.
 
 Only in dimensions - but they became much slimmer in the same step.
 I.e. the volume has been constant.
 
 And while modularity has a cost, it can be offset by economies
 of scale (both in terms of production as in terms of

Hi Stefan,

Am 25.09.2013 um 05:01 schrieb Stefan Monnier:

 The main problem I see with such Free and/or Open phone is the small
 production syndrome.  Small productions mean high prices and low
 reliability, whereas we need reasonable prices and reliability.

Yes, small production is the key problem.

I don't see reliability as a problem because it depends on what type of 
reliability
you are thinking of: component, software, hardware, production, or availability.

Each one can also be achieved with small production batches and improves
with experience of the team running such a project.

 
 So we need to focus on making larger production.  For that, we need to
 widen the target market.

Yes, this is the core idea behind the Neo900 project - find a new market
for an almost existing design and modifying it a little while sharing as many
components as possible.

In essence the Letux 3704 and Letux 7004 projects are no different from that.

  I'm not sure how best to do that, but
 I think the key is in making products that can be used in more
 situations.
 E.g. the EOMA project comes to mind: a single SoC card can potentially
 be used in various devices (tablet, router, NAS, ...).
 
 If the core part of the hardware could be shared between communities
 such as Openmoko (free phone), Raspberry, etc.. then it'd be easier to
 get that core part produced at reasonable cost, and to have a reasonably
 reliable kernel running on it.

In essence it goes to a modular approach - but modular typically drives
cost up (at least for the version having the highest production numbers)
and is in strong contradiction with miniaturization of handheld devices.

And another factor is that producing anything in higher quantities in advance
means that someone is willing to put more money on the table in advance,
not knowing if the product finally sells. I.e. the financial risk goes up.

We all know that there are 10 times as many who would like to have something
different than what is available... And sometimes nobody wants what has been
made available.

Some other thought: it must not be a module that *we* produce (like EOMA)
to get production numbers up.

It would be sufficient to bundle buying power (by summing up # of units
for different projects), so that we get existing modules cheaper. I.e. if all
projects would use let's say an DM3730+Memory, they still can be soldered
into different devices. Or WLAN/BT and UMTS are already coming as
SoC/MCP modules.

So the trick is to use a bigger shopping bag and make a different meal

Hi kardan,

Am 24.09.2013 um 04:52 schrieb kardan:

 Hi,
 
 I would like to add production stories to the website. Also more info
 about the companies that produces the prototypes so far would be nice.
 There is nothing available about hardware[1] or involved companies what
 I could put to the website.

For production stories you can look into the youtube videos we have. But there 
isn't more raw material available and I don't think people want to invest time 
to dig into history. So we could work on better documenting future production 
runs.

 
 Have there been any requests so far or do I need to start from scratch?
 Is there a list with all the parts and selling companies somewhere?

No.

There have been several component sources, the main ones beingAvnet, DigiKey 
and Mouser as distributors and some have changed between. But if you buy at a 
supermarket, you just get the information these grapes are from spain, greece 
etc. and fulfill this or that quality criteria but no other details. So all we 
know is that all components are ROHS certified and lead-free solder paste has 
been used.

Another story is that, there have been experiments with different solder pastes 
and flux to find out why there were production problems. AFAIK there is no 
documentation about that. But it turned out that the soldering process itself 
(hot air reflow vs. vapour phase reflow) is the most critical thing.

But I am not sure if this approach leads to anything useful.

It appears to me that you focus in the fair production aspect and want to 
/analyse/ what has been done 1-3 years ago. This IMHO does not help anything 
for the future, since a fair produced product must be /designed/ for fair 
production and when we started this topic was not yet known and popular as a 
goal at all.

So if you want to see a GTA04 where each part of the production and device is 
documented you may even have to start to design a new one :(

 Antwort an: OpenPhoenux Community commun...@openphoenux.org
 
 Hi all,
 we are happy to invite to the 5th Open(Phoenux) HardSoftware Workshop in 
 Munich, Germany.
 
 The idea is a 2 days weekend meeting (quite informal) to discuss about many 
 topics around open hardsoftware
 like Openmoko, GTA04 and other topics. It is a mix of presentations, 
 tutorials, workshops and we also did have
 some soldering session.
 
 Since this quite well matches with the ideas and targets of the Openphoenux 
 community, we have renamed
 it slightly this year to be an OpenPhoenux Workshop.
 
 For details please look at and pre-register (i.e. vote for a weekend and make 
 proposals for topics):
 
 http://www.ohsw.org/
 
 There you can also find the topics, slides and some videos from previous 
 years.
 
 For this year's workhop, please suggest topics you are interested in (e.g. 
 Neo900, future Kernel development, ...).
 
 Please note that this page is in German as it is (was) a Germany centric 
 workshop in the past, but
 we are open to make it more international - if we have attendees from 
 non-german speaking countries.
 
 BR,
 Nikolaus

 Hi all!
 
 I actually think this is a great idea! I always liked the N900 formfactor. 
 But 
 is it technically possible? I remember somebody mention that the option modem 
 is quite big?

Yes, but it is the flattest one we could get. And from the photos of the N900 
board I have
seen they even need more space for the separate modem chips.


 And if there will be a redesign the fit the gta04 to the n900 
 will it possible to update the specs a bit? faster cpu and stuff like that?

Faster CPU: yes - the idea is to use the 1GHz DM3730 which is 25-30% faster
(at least at peak performance - if clock is reduced to 200MHz it is also slow).

 But to be honest, i will probably not buy this device if it has the same 
 problems the current gta04 has. (power usage and modem enumeration)

Well, we can't say if it will have the same problems - and even if the problems
if the GTA04 are really problems or just lack of a solution.

And, I must warn a little - a Neo900 design may have other problems
we will only see if it has been built and tested by hundredts of users.

Am 26.08.2013 um 14:35 schrieb Sebastian Krzyszkowiak:

 Hello!
 
 Short introduction, as I was rather inactive in this community
 recently: I'm dos, long time Openmoko supporter, owner of GTA02 and
 (now broken) Nokia N900. Few years ago I was quite an active developer
 of FSO (opimd) and SHR. Few days ago I've created website draft for
 GTA04.
 
 As we all know, GTA04 project has few non-technical problems. Poor
 demand is one of them, poor availability of parts is the second one.
 Those two problems together are pretty much show stoppers, cause if we
 fix one, the second one becomes harder.
 
 But Joerg Reisenweber came up with brilliant idea of adapting GTA04
 board into N900 case. Why?
 - second source N900 housings are very cheap and available on eBay in
 big quantities - problem with very small amount of Openmoko cases
 solved
 - there are still new spare parts floating around on free market
 
 But using N900 gives us more:
 - GTA04 with physical keyboard!
 - screen that doesn't appear to be off in full sunlight
 - it seems that while some people like Openmoko case (I do), most
 rather think it's nice idea, but I wouldn't show up anywhere with
 such a brick :( N900 case seems to be more commonly accepted by
 public ;)
 
 Wait, there's even more!
 - if done right, we can engage Maemo community and increase the demand a lot!
 
 There are LOTS of broken N900s in possession of Maemo community
 members due to problems with faulty USB connector and GSM modem. Many
 of them (owners ;)) are waiting for proper N900 successor that never
 came (N9 is not, and Nokia is not interested in platform anymore at
 all).
 
 This might be great time to merge efforts from Openmoko/OpenPhoenux
 and Maemo communities. Neo900 project can benefit from both of them -
 there will be QtMoko/SHR/Replicant on the one side (it's just modified
 GTA04, so running all of them should be very easy), and there will be
 Maemo, Meego and maybe more porting initiatives on the other side.
 Joerg's idea includes full port of Maemo 5 (Fremantle) to allow N900
 users to have drop-in upgrade - just like now GTA04 is for GTA01/02
 owners. I think that can increase interest a lot!
 
 For now we named it Neo900 - making nods to both N900 and Openmoko roots :)
 
 I'm super excited about this idea, and it seems that I'm not the only one:
 Look at http://talk.maemo.org/showthread.php?t=91142
 
 You can also read logs from #maemo from yesterday and today:
 https://mg.pov.lt/maemo-irclog/%23maemo.2013-08-25.log.html
 https://mg.pov.lt/maemo-irclog/%23maemo.2013-08-26.log.html
 
 It seems there is some interest, and that's just on Maemo side :)
 
 What do you think?

Very good idea. If we can use the same basic design both, the GTA04 and
the Neo900 could have many common components. And adding the
number of chips bought of one type will help to reduce the purchase
price of both. So trying to merg this is to the benefit of both.

 monopoly on production within the community.

No.

  It does not share the

Yes. This is no difference to Openmoko, Inc. did since 2007.

 This is the same situation as a community that is beholden to a company
 producing proprietary software.

No.

  The GTA04 is like proprietary hardware.

No.

For proprietary hardware you have no schematics, no clear identification of
the components, some custom made components without any information,
and no documentation which GPIO is doing what.

 We have schematics in a .pdf file but nothing else.  

Yes. And the PDF is the source. You can run OCR and convert it into any
format you like. And modify it as you like. What else do you expect? More
convenience?

The Schematics and the component placement chart of the GTA02 - both
as a printable PDF - were sufficient to design the GTA04 board... So it is not
lack of information if nobody is picking up the GTA04 design...

 There is no shared
 repository containing the source files for the schematics or the PCB
 designs.  Nobody can commit design fixes.  

Is this a requirement for FLOSS that you can commit anything directly to the
original repository? Do you have commit access to the master branch of
kernel.org?

Anyways, you can make change proposals and there are others who
sign off and accept your patches into the master if they fit into the
project goal and fit to some design style and rules.

So if you want something to be changed, please write me an e-mail (in
natural language) with your patches. Or propose it here on this list.

 The community is not
 iterating the GTA04 design.  The community is not working together to
 create a free phone.  Instead, all we do is discuss and argue about one
 company's product.

The community can help much better in other areas, e.g. marketing, spreading
the word, software, etc. because high density PCB design needs a very specific
type of knowledge that isn't widely available. And, the PCB must be 100% correct
or even 100.00%. so it is better to have a very small team.

 A lot of people have come up with various ideas for modifications to the
 GTA04.  Some of them simply require some soldering which is no problem.
 However, some require a redesign of the board.  To my recollection,
 nobody has ever pointed out that this isn't possible unless Golden
 Delicious do it.  The fact that only Golden Delicious can do it is bad.

No. Because you can do it as well.

You can start to learn how to design PCBs, aquire some PCB design tool,
capture or convert the schematics, and make your own layout. Then, find
someone who does production for you.

 
 Despite describing the GTA04 as Open Hardware¹ and stating that the
 aims of the community are for DIY hardware², Golden Delicious does not
 release any source files for the hardware it produces.  There is no
 community of hardware hackers contributing to shared PCB designs.

Because designing such a difficile and miniaturized device is more challenging
than the average hardware hacker is capable to do.

 I suggest that the community changes from consuming hardware designed
 and built by a single controlling entity to producing one or more Open
 Source Hardware³ phone designs which can be taken as a base, modified
 and manufactured by any party.  For example, a board design could be
 used in the same fashion as the GTA04, as a replacement for GTA01/02
 boards but could also be modified by the N900 community to provide an
 updated board for their phone.

It is possible to design a board for that by the procedure descibed above.

 I suggest that Golden Delicious release the source files for the GTA04
 board in order to assist this effort and act as a base for the first
 community phone design.

Essentially you are mixing openness and modifiability of source and
compiled binary.

The source in such a hardware project is the schematics (which is
open for the GTA04) and the compiled result is the PCB (which is
not easily modifiable, even with proper tools).

It is like you are asking an open source project to publish compiled
binaries, before you call it open source. IMHO this is only convenience.

Finally some more technical aspect: it is not easy to just modify the
PCB to fit into an N900 case. You more or less have to redo the whole
PCB layout process (i.e. the compilation), although the Schematics can
be almost the same. So you virtually want to change

 But it also needs 200 * 599 EUR on the table. Not to start design or
 production (that has become my hobby), but to buy components.
 
 I don't get this passage. Note I am not a hardware expert so it is not
 clear to me how 200 boards can be available in november if a redesign
 with a new display takes nearly half a year.

The displays (Toppoly) are no longer in production but we have some in stock.
And, the GTA04A5 board is designed to use them. So it is just about producing
again based on the existing design.

Changing the display to a model that we can buy in any quantity from running
production needs to redesign the PCB and test and qualify that for production.

 Where are 130+ displays supposed to materialze until november? I

Sometimes, companies buy components and after 2 or 3 years they end production
of the devices using these components. And then, they try to sell their 
overstock.
There are component brokers who are experienced in getting such old/obsolete
components.

 understand your assumption that there is some stock somewhere and would
 love to see that proven with a reliable price tag.

That has not been researched - and may change every day. I can't tell if it is
easy or difficult before someone starts to really buy them. It may be just some
Alibaba search or a search for a needle in a haystack.

But *I* will not start this research before it is clear that we need them, 
because it
would be waste of my lifetime...

 considered standard and what the GTAxx is prepared to deliver rather has
 widened.
 
 to get even close to standard (and thus being a realistic alternative for
 smartphone users), the project would need backing of a far more potent
 entity than this tiny community is -- both money- and publicitywise.
 
 since the GTA02 i spend about 2000€ on this project, maybe more (well, i
 can afford it and it was worth supporting the idea behind it), and in my
 very personal and subjective opinion, the GTA04 has been a huge
 disappointment. i wouldn't spend the equivalent of a highend, state-of-art
 smartphone or even tablet just to buy yet another even more outdated
 device, free or not. compared to the shortcomings of the GTA04, even
 complete freedom is not sufficient to justify that amount of money.
 
 whenever i told somebody who had heard of OpenMoko that there's a
 successor, they were surprised -- and when i told them the features and
 the price, i got an incredulous grin and the question if someone really
 believed that people would spend that amount for such a device.
 
 i am still undecided if i should admire or pity the thread starter, if he
 honestly believed that this community would be able to succeed where
 ubuntu failed -- and on top of that to jump from todays GTA04 to the
 device as imagined by ubuntu ...
 
 all things considered, the realistic path is imo to cater to a tiny niche
 of institutional customers -- like jörg(?) proposed.
 while i am personally rather fond of the original GTA01 case (and think
 that's almost the only tangible unique feature), i, too, would prefer it
 to pick up where the n900 left. maybe then it could even tap into the pool
 of still active n900 fans ...
 
 Very well written. I can add a few more points.
 
 For me GTA04 is not usable as daily phone. It's now collecting dust in shelf. 
 Why?
 
 1/ poor power management
 2/ bugged reenumerating modem
 
 GTA04 is good enough only in some situations. E.g. ok if i carry it to work 
 where i can anytime charge it. When i am on bike 150km from home i must have 
 reliable phone in case that the bike breaks up or in case that i need map.
 
 I took GTA04 with 2 batteries and N900 on my bike trip this summer. I used 
 N900 as a phone with SIM card. GTA04 was switched off - i just used it for 
 GPS. But after 4 hours one battery was empty and second battery was 50% empty 
 during one night in suspend. On the other hand N900 was working whole 4 days. 
 I used it for calls, for wifi in camps and in the end even for GPS.

That is something I still don't understand. From a power budget the modem is
specified to have 3-10 mA in suspend while registered to a base station.

I have even verified this with an ampere-meter.

And there is only one potential deviation - if there is some attenuation (e.g. 
wall)
there may be a situation where the modem receives the base station well and
tries to answer/register. But since the base station does not receive it at 
all, it
tries with high power. In this case the modem current increases to 50-100 mA.

BTW: this is the same with almost all mobile devices.

So it must be something in the OMAP system and that is IMHO the same as the
N900 has... So pure kernel code.

BTW: this would not change by redesigning the GTA04 into a spare N900 case...

 
 I though that self-made open source phone will have good power management. I 
 though it will be easy or at least possible to identify where the power goes. 
 I am even more dissapointed that noone except Neil Brown tried to improve the 
 situation.

Yes, that made me wonder as well. It appears that it needs some very special 
skills
we don't have in our community. Or we have but those members have no time.

 Event GTA02 is s much better in this area. For me this is so 
 important that GTA02 is now much more usable then GTA04. It's like having car 
 that can go just 30km.
 
 And the reenumerating modem - i really dont understand why we havent tried 
 newer firmware. For me missed calls is quite serious problem.

Because the upgrade firmware did not run on the kernels for unknown reasons
(failed with segfaults). And because we must make RMS believe that there is
no way to upgrade the modem firmware from user space.

 I dont understand why produce more phones until these problems are fixed.

I don't know how to fix these problems without producing more phones. Especially
there is one issue in the IrDA/RS232 driver which prevents the kernel to power 
down
both and the ITG3200 may also draw some mA. This all would be fixed in the

 That's insane. HNS and his small crew invested substantial time and *money*

 This would allow golddelico to continue their awesome work.

Exactly.

 But what you are interested in seems not at all focused on joining efforts 
 but 
 to fork and try on your own if you could do any better than Nikolaus.

If someone is not happy that Goldelico wants to continue and asks for payment,
please DIY. But start on the green field (yes, as prepared by Openmoko) as we
have done.

And please do it cheaper. Maybe I can learn from you how you do that.

 I consider this rogue and silly. 
 Plus you evidently have not the faintest idea of what's the real troubles in 
 hw design and production, otherwise you'd not think you could do 
 substantially 
 better than goldelico. Every fool can draw up a nice (though most certainly 
 not bug-free) schematics, and even creating a PCB layout is not that 
 complicated, there are FOSS tools for that. The problems are somewhere else, 
 and a project that considers PCB gerbers of GTA04 as an indispensable 
 prerequisite for a new design, well such project is doomed to fail from 
 beginning and I'd consider it detrimental to the actually existing and 
 working 
 GTA04 project since - even if not the manpower of those devels who focus on 
 the new project due to lack of expertise and insight into where the major 
 problems of any such project are - it however will deprive GTA04 project of 
 possible customers that might contribute to GTA04 (and successors) with their 
 money, if they weren't lured into waiting for another competing project 
 started by a few guys who obviously think they can do better since they don't 
 know sh*t about hw manufacturing.

 my 2 ct about this weird arguing here.
 
 A word to Nikolaus: I'm a bit sad that you ignore the fact that openmoko 
 *did* 
 share gerbers, PADS project files, BOM, whatever, on request. We shared 
 everything, sometimes under a NDA when we had to do that way.

Sorry, but I didn't know that until now. I just knew about the PDF schematics
and the BOM and the 3D CAD data and the component placement plan.

This was enough to start the GTA04 project, so I did not research further into
what else would have been available on request.

 And maybe you 
 didn't know but Wolfgang pestered all EE pretty badly to allow community 
 contribution, just we never really could come up with a workflow how to make 
 such process work. The problem with that is the expertise of community 
 contributions which take ten times the manpower of company EE staff to 
 explain 
 why it can't get done this way, than what company EE would need to come up 
 with an own better draft for the same thing. 

Oh yes, many cooks spoil the soup.

In my experience it needs a small team at one location (so that you can
really meet for discussions). And a team that can work in stealth mode for
some time to come up with a proposal.

 OM been a company with lots of money so we didn't worry too much about 
 community competing projects, and eventually I even convinced Sean and 
 Wolfgang and others that no commercial competitor will snatch away and copy-
 cat our product either.
 Bottom line: to claim OM never allowed community contribution and never 
 shared 
 PCB or project files is pretty incorrect.

Ok, now I know. Thanks for clarification!

But anyways, it was not necesssary to fork the project to develop a GTA04.

Developing the GTA04 did need something else. The believe that it can be done, 
is
useful for the community and being crazy enough to do it.

Therefore, I see all requests to get the projects files as distracting from the

we have. Which are component and production cost being higher than everybody
would like to see (me included). And nobody to find a solution. Which is either

I don't understand that. The reason of open source is that you can rebuild
the system if the original designer decides not to continue and maintain
the system. For that you need the sources in some open way.

A different story is that FSF did start some collaborative projects based
on the GPL which of course needs people to be able to work on a common
system as a team.

Back to the GTA04, you have all you need in PDF format, i.e. you can
maintain your GTA04 in any way you like. You are absolutely free to
start to rebuild it from scratch or modify it. Nobody is stopping you from
doing it. The licence for the PDF documents permits you to do it.

So what is missing? I only see the convenience aspect.

And regarding barriers, I rather think that asking people to install and
learn the same schematics capture system that we use is an increased
barrier over the current situation.

The current mode of collaboration is that every e-mail telling some change
request in plain language is welcome and will be translated to the required
data format to produce a new PDF. This work is done by us - but what is
bad about that? Only that you can't do it. I don't consider that as a problem.
Neither for you nor for me.

And as written somewhere else, there have been several proposals from
the community that were included in the GTA04A3, A4 and A5 designs.
So I still don't get the goal you are arguing for and how it improves the
acceptance of the GTA04.

 So I'm wondering about the difference between the two.

the idea is that anyone can even use the adaptor board

For the PDF the licence is NC. But note that this licence

Like you can learn from a book and use the contents.
NC because it requires any commercial use to contact us.
Commercial use means that someone wants to copy

This does not preclude any licence and use, but allows
to think to ask for some charge for the benefit of the project.

Hope this explains the reasons of the different licenses.

 There seems to be a misunderstanding here.  I'm not accusing anybody of 
 hiding problems.  I'm saying that there are problems other than money which 
 are preventing the successful production of a free phone.  Those other 
 problems have been discussed openly on this list and others.

To some extent you are right. There is a problem one would call a structural 
problem. Sort of an equation system with 0 solutions.

 everybody (even you) can start a fundraiser.
 
 Of course they *can*.  But they're *not*.  That's the point.

We see from this discussion that everybody wants something else, but not what 
would be easily available.

If 200 people agree to put 599 EUR on the table we could start production 
tomorrow (well, we need 6-8 weeks to get the components) and 200 GTA04 boards 
would be available in November.

We could also order 200 3D-printed cases, earpieces etc. to make complete 
phones. One issue is that we have just ~70 display modules, and they are out of 
production for a long time. But there may be some remaining stock in Asia, so 
it appears to be a solvable problem.

Doing a redesign for a different display, different case (N900) is also 
possible, but takes more time (estimate 4-6 months).

But it also needs 200 * 599 EUR on the table. Not to start design or production 
(that has become my hobby), but to buy components.

Now back to the everyone wants something different issue of the problem:
* people want a different device (N900 keyboard)
* people want an Überphone (Ubuntu Edge)
* people want 100% freedom in WLAN, UMTS modem etc. (discussions on this list)
* people want to have a device more innovative than Apple and Samsung together

And of course - as Christoph points out - cheaper than anything else.

I can completely understand all these wishes. Even that it should be cheaper 
than everythin else. But having the best at the lowest price is a contradiction 
in itself.

It can be fulfilled better, the higher the production volume is. It is a basic 
law of economy that only #1 and #2 producers can get big margins, big enough to 
stay #1 and #2 by spending a lot of money for innovation. It is a law that 
nobody can break - like force of gravity... If you want to study this, please 
ask yourself why you get the high capacity memory chips you would like to see 
in a GTA0x only from Micron, Samsung these days and nobody else.

At what position are we? We (with this I mean any team formed from the 
community) are probably #5000 in the smart phone or portable computer 
business...

From this, I think nobody is doing fundraisers or developing a new GTA0x 
because they either know and see these economical implications or at least 
have a good gut feeling that they can only loose money they don't have.

There are unsuccessful campaigns (Ubuntu edge) and successful ones. If you go 
deeper into successful campaigns, they offer something really new (wrist 
phones, wrist displays) which the big companies do not even have. So for a 
short time frame the early innovator is #1 (Pebble) and #2 (Meta-Watch). But 
as soon as Apple and Samsung will enter the game arena, things will change 
rapidly...

There is only one factor I can see that would change the game: if more people 
see a real value in supporting what we all would like to see. And supporting by 
paying more (and not expecting less).

green light: close to 200 preorders or wishlist entries in the shop.

It is like a train (without fixed schedule) waiting at the station for enough

Yes, a vintage train is perhaps a good comparison with our GTA04.

It costs a lot of money and volunteer work to keep it in operation at a very 
irregular schedule. And it is more for fun than for real transportation so that 
passengers pay twice or three times a ticket would cost for the same distance 
in a modern and more comfortable train. And having a fixed schedule.

But 99% of the world population would never see a benefit in riding a vintage 
train to go from A to B, e.g. for going to daily work.

Which is similar to our situation that 99,99% of the world population doesn't 
see a benefit or an impulse to buy a 100% open device or a community built

Re: Building a new totally free phone

2013-08-23 Thread Dr . H . Nikolaus Schaller
 
 However, can GSM really be a base for secure communication anyway?  

IMHO the need for the GSM stack being open sourced is largely overestimated.

Security experts say that the question is how to secure communication over an 
unsecure communication medium.

Depending on which level you want to work, you can try to make GSM more secure 
because it is communicating over an inherently unsecure/open medium 
(electro-magnetical wave broadcast).

Or you can just use what others have built into a black box (i.e. a modem with 
some AT commands). They promise that it is secure enough. But if you want to 
be really secure, just wrap the potentially unsecure channel and encrypt the 
data sent over it.

BTW: all the recent nsa/prism things have shown that it is not sufficient to 
make a fully transparent (aka open sourced) terminal - if it is easy enough to 
tap the network nodes. Or the servers you are communicating with. I.e. securing 
yourself is best done if you put yourself into eremitage...

So in my view, spending additional work to get an open sourced GSM or even UMTS 
firmware stack is a nice excercise for embedded and real time communication 
protocol engineering, but does not make anything more safe or secure than using 
a black box module, because it just tries to increase security of one small hop 
instead of end-to-end.

In other words: security measures must be done on the highest layers of the OSI 
reference model, not on the lowest ones. And that is the area of the 
application processor and OS. And of course documented schematics help to 
understand if there are potential backdoors to circumvent the OS or not. So we 
need a device where you have control over the OS, but not necessarily over the 
inner workings of all peripherals.
