OLPC Debian Jessie

I've been running Debian Jessie on my XO-1 for about a week. These 
<http://pastebin.com/EktdMcjk> are the instructions that I wrote 
detailing my process. Can somebody go over these and make sure that 
there aren't any errors or omissions before I post this on the wiki?

Thanks,
Nathan

Re: Devel Digest, Vol 109, Issue 19

I also believe based on some observations in Rwanda that the firmware 
was modified.

Error on XO4 update to 32016o4.zd

Hello OLPC devs,

I tried to update an XO4 touch to 32016o4.zd. It looked like it went
fine, but...

It won't boot, with the following error (see image attached).

Hints are very welcome. Impatient young one around.

:-)

Announcing OLPC OS 13.2.4 for XO-1.5

G'day,

We're pleased to announce the release of OLPC OS 13.2.4 for XO-1.5.

It is Sugar 0.104 on Fedora 18; very similar to 13.2.3 but with some
fixes to software update and language control panels.

Details of new features, known issues, and how to download, install or
upgrade can be found in the release notes:

http://wiki.laptop.org/go/Release_notes/13.2.4

Many thanks to all contributors, testers, upstreams, and those who
have provided feedback of any kind.

Developers who need restricted software components, such as the Adobe
Flash plugin, GStreamer MP3 codecs, should contact me directly for
assistance.

32016o1

adding codecs to 13.2.3 on XO-1.75

Is it normal that the following command fails with a series of "no such file or directory" messages?

Here's the command suggested by http://wiki.laptop.org/go/GStreamer#Adding_codecs

sudo yum localinstall -y \ http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \ http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm && \ sudo yum install -y gstreamer{1,}-plugins-ugly gstreamer-plugins-bad gstreamer-ffmpeg

Are there any alternatives?

Or conversely, if the above wiki page is very stale, should we post a warning there?

Re: Devel Digest, Vol 109, Issue 9

I only wish use of laptops was long enough for any of this to matter. At 
the deployments I know about,
access to laptops is less that three hours per week.

That might help, for particularly large activities.

No, it might not be power demand, it is more likely to be timing.

To check, make sure the laptop is unlocked, and add this to the second
line of the boot/olpc.fth file:

    dev /sd  patch 2drop cb! sdhci-card-power-off  dend

This will prevent the firmware from turning off the card reader before
booting Linux.  The card reader will stay powered on.

A 16 GB SD card is modern.  It draws less current than the cards for
which the XO-1 was designed.  The XO-1 SD card reader doesn't have
discharge clamps on the power rails.

When a USB ethernet adapter is present, the firmware takes longer to
probe the USB bus controller.  When on battery, the firmware may take
longer to probe the embedded controller.

The combined effect is to change the timing of power on and power off
events for the card.  Cards are known to be confused if the voltage
does not fall fast enough, and without discharge clamps and with a
modern card, this is more likely.

"occasionally hangs" means you're right on the border of it working or
not.

(p.s. there is some old code around that tries to patch
card-power-off, most recently seen in Jhon Diaz' repost of the Puppy
Linux olpc.fth ... but since card-power-off is now a defer, it doesn't
patch.)
