end of a XO-1

I hope this isn't completely off topic for this list. My idea is that
posting this report here might be useful to someone in the future
searching for related information.

Back in 2008 I bricked my XO-1 B2 (128MB) machine by upgrading to a
firmware that was incompatible with it. The original firmware didn't
have the commands needed to boot SqueakNOS and I wanted to play with
that system. I downloaded the needed software (spiflash.dic) and
firmware (q2c27.rom) to fix the problem and opened up the machine. The
serial connector CN24 was missing, but I made a five wire cable from an
old floppy cable and my brother-in-law, Fred, carefully soldered the
wires to the missing connector's solder pads on the board. The plan was
to use the IDC connector at the other end of the cable to connect to a
Xilinx ML401 FPGA development board configured as a serial adaptor.

I was using the FPGA board for another project and only got around to
trying to fix the XO-1 last week. The XO-1 was also missing the Recovery
Mode Jumper Block (CN31) so my father taped a small piece of metal
shorting all four solder blobs. I checked that the FPGA was generating
65MHz for the EC chip and using a serial terminal application on the PC
I could see that characters typed on the PC keyboard were reaching CN24
on the laptop.

Plugging in the laptop's power brick (with no batteries) made the
message "213423:SCI:40" appear in the terminal application (the first
number wasn't exactly that and changed a little each time - it was some
kind of time stamp). Unplugging caused a similar message. Eventually I
noticed that pin 1 of CN24 is supposed to be 3.3V from the laptop to the
serial board and not from the serial board like I had thought. I
reconfigured the FPGA to stop sending 3.3V on that pin and now the

Testing 40002au4.zd image on XO-4

Maybe this information is already known.
Played around and found the following:

1. Piano and Write not working.
2. Browse will work but sometime it just kick you out :-(
3. Other connected XO will not show in neighbourhood.
4. Picture taken by record normal but when view from clicking the picture "overexposed when access from the journal.
5. Can't get out to Gnome

XO Keyboards

Hi All

Can anyone suggest where I might be able to get some replacement XO-1 / XO-1.5 keyboard membranes in US keyboard layout please.

Wr have around 20 XOs with missing keytops where the membrane has been damaged in use.

Thanks for any suggestions.

Regards
Terry

Re: [support-gang] Firefox won't install on XO-1/Gnome; other options?


On an xo-1, using the official 12.1 from download.laptop.org as a base, I am able to successfully yum
install firefox with the 2 new dependencies (fedora-bookmarks, xulrunner) and 7 updates - mostly nss*
modules). FF works fine with the Google and Gmail sites.

Easier to make a new XO-1 build using olpc-os-builder that already has
firefox in it, than to deal with all the things that have to be done
to bolt it on later.

‎Firefox has a lot of dependencies, it has to bring the whole xulrunner thing back, so the out of space may
be disk, not memory

Hi,
This is because by default /tmp is only 50mb on XO1.

Yum is a real memory hog.

What I do as a temporal fix is:

mount -o remount,size=200m /tmp

I second James's discouragement of using private lists to give public 
support.

Sebastian

rpmdropbox is not working

Hello everyone,

It seems that OLPC's rpmdropbox [1] is not working. Who is maintaining that repository now?

Yum random crashes in XO4 f20 images

Hello Peter,

I am have been building a Fedora 20 image for the XO4, and I am seeing memory corruption problems while running yum in these images (please check the logs [1,2]).

To give you some context, we are using olpc-os-builder (master [3]) with fc20 repositories plus a few hand-crafted packages such as the kernel, systemd and xorg, taken from previous Daniel Narvaez efforts [4,5].

These crashes happens randomly when yum is running, by calling yum update or when olpc-os-build is installing system packages.

James Cameron, who spent some time researching about this issue, speculates that this problem could be caused by: (a) using older kernel that was compiled (possibly) with different options compared to f20's, or (b) a faulty glibc library.

I was wondering if this could be related to something else, something more specific to  yum or python arm binaries (?).

I would sincerely appreciate any guidance you can provide to start discarding possibilities and try to debug this issue.

Thanks in advance for any help you can provide!

Regards,
Martin.

/etc/hosts busy??

When I tried to update /etc/hosts, it says busy.  I thought I'd been doing 
this for years, so I'm a bit surprised and/or confused.

bash-4.2# mv hosts /etc/hosts
mv: inter-device move failed: 'hosts' to '/etc/hosts'; unable to remove 
target: Device or resource busy
bash-4.2# rm /etc/hosts
rm: cannot remove '/etc/hosts': Device or resource busy
bash-4.2# mv /etc/hosts /etc/hostsx
mv: cannot move '/etc/hosts' to '/etc/hostsx': Device or resource busy
bash-4.2#

It used to work.  I did it sometime after early June.

bash-4.2# ls -l /etc/hosts
-rw-r--r-- 1 root root 1504 Jun  4 22:07 /etc/hosts
bash-4.2# 

My usual approach for things like this is to find the program that has the 
file open, but I can't find it with lsof.  ??

bash-4.2# lsof | wc
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
   4658   44081  503329
bash-4.2# lsof | grep hosts
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
bash-4.2# 

Does anybody know if something is hiding in that error message and/or how to 
find out what's going on?

cp -p worked, but I'm still curious.  I'm pretty sure I used mv last time, 
but maybe it's been busy for ages.

Bitmap at the power off of the XO

Hi all,

Is there a place where I can find the last bitmap display just before the power off of a XO ?
I mean the one with advice regarding charging, don't drop it, be careful with the battery, ...

(unknown)

Hello James,

As you know, I have been building f20 + S0.102 images, using a XO4 with dnarvaez f20 image as building machine. Also, I am working on top your OOB branch.

I was able to make these builds without much trouble, until today, when I started to get a glibc errors (please see attached files). The errors occur during or right after the RPMs are being installed in the image,  and quite consistently, even after reboots.

I reverted my changes in OOB, to the last commit I was able to complete the image, and I still get these errors, I did not change anything in my setup.

Any ideas of what this could be?
