Re: question about how to re-flash the XO

2009-02-28 Thread Mitch Bradley

 Suppose I have a file 'foobar.img' on an USB stick.  On an unsecured 
 XO, I'm at the 'ok' prompt.  What is the difference between using 
 'copy-nand u:\foobar.img' versus using 'update-nand u:\foobar.img ??

 Thanks,  mikus
   

update-nand performs the secure update procedure that uses fs.zip as 
the source file.  It supports creating partitioned images via the 
command mechanism defined in 
http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater

copy-nand performs a simplified non-secure update that uses foo.img 
and foo.crc as the source file.  It just blasts the raw data onto the 
NAND, block by block.

Re: Price point plus sales to individuals

 Okay, so those of you who are keen on there being a way for individuals
 to buy XOs at $2xx dollars should place a volume order, set up a web
 site, and start raking in the dough.

Earth Treasury has wanted to do that for more than a year, although
raking in the dough was not part of the vision. It would be hard
work for a thin margin at the best. It has not been possible, for
several reasons.

o Initially, it was cash in advance with no delivery date. Sixty days
later, we would get a date within the next year. So delivery within
three months is a great improvement.

o We never got the same terms twice when we asked.

o We didn't have and couldn't get the financing.

o GiveMany/Save the World for orders of 100 or 1,000 units was cancelled.

I will now assume some fudge factors that can be replaced with real
numbers with some research. So we can say that we can order 10,000
units @ $200 and change, or $2 million+. There is a volunteer support
gang, which we assume we can work with. Amazon is willing to handle
fulfillment, in principle, if OLPC asks nicely, but only if we can
assure delivery of orders within a month. That means we have to place
our order at least two months before we can start selling.

I will also suppose that we can get firm terms so that we can present
a real plan to any potential funding source. Then it turns out that we
are able to begin the discussion with several possible sources, and we
have in fact started a discussion, and will start others.

This is not to say that we have a full business plan, and we certainly
don't have funding lined up, but we are in the range where we can
discuss the possibility. So if anybody wants to help write the details
of a business plan and some funding applications (commercial or
non-profit).

The plan also has to include setting up paid support services for
buyers to deal with necessary infrastructure, training, developing
teaching materials, and the like. We have started the Digital Textbook
project with various partners, and we have a good idea where we can
get the other partners needed.

 Obviously you guys know something about making a few bucks per machine
 that has eluded the OLPC organization, so go for it.  As the old canard
 says, put your money where you mouth is.

I'll have to see if I can get someone who actually has money to do
that. I'll let you know.

 Absolutely true and I'm not sure the capital would be enough. Its difficult
 to imagine OLPC entering a retail channel, directly or indirectly.

We aren't talking about retail at this point. The idea is to support
schools, museums, and the like to get 30 or more each.

Eventually I would like to see GiveOneGetOne revived, but not with the
abysmal marketing we saw last time. OLPC is one of the great brands,
if managed appropriately.

 Perhaps I
 have misunderstood the intent but thats what it seems like when we talk
 about individuals buying small volumes, perhaps simply to tinker with a cool
 machine.

I am working with The Tech Museum of Innovation in San Jose CA, which
wants 50 for a lab exhibit where school classes could get a working
demo and a peek at software in development. Other museums such as the
Exploratorium and Zeum in San Francisco and the MIT Museum have
expressed interest in creating a variety of exhibits. It's a cool
machine, but they want to use it, not tinker with it.

We also want to support home-schooling groups and other small trials.

Another reason for this is to educate the public and to create the
political will to get XOs into US schools, and to get the US to fund
XOs in developing countries.

 In the immediate future I don't see overwhelming evidence that OLPC should
 devote resources to satisfy every volume demand in every channel. The outcry
 over discontinuing Change The World was far greater than the willingness of
 people to put up money.

I will see what I can do. There is interest in funding a program such
as I have outlined, which is quite different from OLPC's program.

 Very often those willing to pay were small-volume
 resellers.

 OLPC is better off focused on its engineering, advocacy and implementation
 efforts AND supporting accompanying networks of olpc-phile communities.
 Running an effective developer program is fundamental to all the above.

So what is this nonsense about OLPCorps?

 Good point, but no, rxvt is being used with a bitmap font, and it is the
 same size on debxo 0.4 and 0.5, using a side by side comparison of two
 XOs.  An 80x24 character cell window takes up the same physical space on
 the panel.  xwininfo on both shows 979 x 580 pixels.

 but what was reported was that an 80x24 window didn't see much 
 difference, but a window showing more characters took significantly 
 longer.

Yes, that's expected ... when there is a shortage of CPU cycles, a
larger window would cause more work, and would appear slower.

  Yes, something is wrong.  Have you another XO you can test?
  
 I installed latest 
 xserver-xorg-video-geode_2.11.0-0.3_i386.deb
 from:
 http://lunge.mit.edu/~dilinger/debxo-0.5/
 It got slightly faster, like 10% but the situation is still roughly
 the same. I don't think it is the JFFS2 as top shows most of the cpu
 time is spent in the Xorg process. 

Only some of the JFFS2 problems manifest as CPU time spent in kernel
threads.

 A couple of suspicious things:
 1, /proc/meminfo shows MemTotal: 221776KB Can someone confirm whether
 this is normal?

Looks normal to me.

 2, Console (without X) is also quite slow. I know fbcon can be slow
 and unlike x terminal it is synchronous so it has to draw every char
 literally but still I didn't expect it to be this slow.

That excludes X as the primary cause.  It suggests a shortage of CPU
cycles.

 3, every once in a while (10 mins or so) there is a message in console like: 
 JFFS2 warning: jffs2_sum_write_sumnode: Not enough space for summary, 
 padsize=-60

That matches a known problem.  The JFFS2 filesystem is in a suboptimal
state.

 4, dmesg is flooded with thing like:
 [ 1950.351880] olpc-ec:  received 0xe3
 [ 1950.351880] olpc-ec:  received 0xc2
 [ 1950.352019] olpc-ec:  running cmd 0x15
 [ 1950.353035] olpc-ec:  received 0x41

That is probably unrelated, and the fragment looks normal.  The EC does
not use the JFFS2.

 I could also reflesh debxo0.5 or latest joyride build to try. Is there
 anyway I can build a set of dat/img files from my current nand so I
 can come back easily?

Not at the moment.  This requires save-nand support for partitioned
NAND, and I checked with Mitch a few days ago on IRC and he said it was
not yet available.

I *think* a save-nand to USB disk will work, but I don't know if a
copy-nand from it will work.  I'll give it a go.

If you wish to save your configuration changes, take a copy of the whole
of /etc, and dpkg --get-selections, and anything else you may have
changed.

Re: question about how to re-flash the XO

2009-02-28 Thread Mikus Grinbergs
 Suppose I have a file 'foobar.img' on an USB stick.  On an unsecured
 XO, I'm at the 'ok' prompt.  What is the difference between using
 'copy-nand u:\foobar.img' versus using 'update-nand u:\foobar.img ??

My question regarded an unsecured XO -- I have /security/develop.sig 
on the (install) USB stick.  Seems like there is no difference then.


 copy-nand performs a simplified non-secure update that uses foo.img
 and foo.crc as the source file.  It just blasts the raw data onto the
 NAND, block by block.

I've been using (as written up) 'copy-nand' to install Chris Ball's 
rawhide-xo images (which consist of xxx.crc and xxx.img on stick). 
[Showed a single area of green squares, then an area of blue.]

 update-nand performs the secure update procedure that uses fs.zip as
 the source file.  It supports creating partitioned images via the
 command mechanism defined in
 http://wiki.laptop.org/go/OFW_NAND_FLASH_Updater

I was able to use (as written up) 'update-nand' to install Andres 
Salomon's debxo images (which consist only of xxx.dat and xxx.img on 
stick).   No file 'fs.zip' in sight.  [Did show an area of blue 
squares between two areas of green squares, then the remaining blue 
area.]

Verified.  save-nand succeeds.  copy-nand results in an unbootable
system, on power-up OFW prompts with ok, and if you type boot you get
Unrecognized program format (sic).

Can you tell me more about this. I installed debxo-0.5 on a usb drive and rxvt
speed seems normal. So it comes down to either the jffs2 or the internal nand.
I thought jffs2 on raw nand is supposed to be better than non-flash aware fs
on a cheap usb stick...
