Description

ATest has Q2C11 firmware. Build 451, 445, and 444 were booted from a 512MB USB flash key. Not booting from onboard flash because flashing Linux images have not been successful on this ATest board. However, booting image from USB flash key works well.

Build 451 (olpc-redhat-stream-development-build-451-20070608_0733-devel_ext3.img.bz2 ) did not boot. OFW screen froze. Serial port console gave the following message:

...
[ 16.360798] checking if image is initramfs... it is
[ 16.455171] Freeing initrd memory: 5518k freed
[ 16.462085] SCI is mapped to IRQ 3

[ 16.481876] olpc-pm: Unknown SCI event 0xff occurred!
[ 16.488236] olpc-pm: Unknown SCI event 0xff occurred!

Okay, get an earlier image to check.

Build 445 (olpc-redhat-stream-development-build-445-20070607_0436-devel_ext3.img.bz2) did not boot. OFW screen froze. Serial port console gave the following message:

(end of serial port console message)

External monitor reported "Video mode not supported".

Solution: Using serial port console, change "1200x900" to "1024x768" in /etc/X11/xorg.conf and comment out "cp -f /dev/X11/geode-xorg.conf /etc/X11/xorg.conf" in /etc/init.d/olpc-configure for X-window to start properly on an external 1024x768 monitor/ATest board.

Sugar, Journal, TamTam, Etoys, TurtleArt, developer console, X-window, and twm are working. USB mouse, USB keyboard, serial port console, and ALSA sound are working. Noticed that Etoys has a new scale mode which is useful for readjusting for 1024x768. TurtleArt is new (as it is not present in Build 406).

This ATest board with 5V transformer consumes ~6W.

This is not a hardware bug, and you should try Q2C17 before we label it a firmware bug. Not getting the right Xorg.conf may be a distro bug, or a firmware bug.

It's also not clear that we want to continue to support A-Test boards.
