Experimental Ångström feed for Spitz

Here is my experimental feed: UTX feed and proposed /etc/ipkg/utx-feed.conf.

The feed is based on the recent org.openembedded.dev branch of OpenEmbedded with very few additional patches (these patches are available here).

There is still a lot of work to make Ångström and OpenEmbedded flawlessly working. That is why I dumped stable branches and I am using the unstable branch, which allows to test latest changes.

Be sure to read notes befor using the feed!

Not valid for current builds, but I can try to build it again: (This feed contains packages compiled with iwmmxt optimization. This is not enabled in the standard repositories and causes few build failures.)

Most annoying bugs

Loading g_ether may hang your boot process. With a combination with broken lo, your local networking it sent to UDC, which does not work. UDC drivers are broken in a wide range of kernels (2.6.26 to 2.6.33), so you can remove it without any problem. If your boot process hangs, reboot into emergency system, mount your root, remove g_file_storage, g_ether and pxa27x_udc from /lib/modules and reboot. Your system should start again.
Possibly broken networking: lo does not go up. See the work-around below. It seems to be a race condition and removing of udev cache may fix it for the next boot.
broken Xorg setup: Edit /etc/X11/Xserver and add this as second line: exec /usr/bin/Xorg -dpi 200 -noreset
comment out all xmodmap calls in /etc/X11/Xinit.d and remove all xmodmaps in /etc/X11.
One coordinate of pointer is rotated (i. e. default) screen mode in the latest tslib. Remove related /usr/share/hal/fdi/policy/20thirdparty/10-x11-input-tslib.fdi, restart hald and use proposed xorg.conf
Copy xorg setting files from ftp://ftp.penguin.cz/pub/users/utx/zaurus/files/xserver-xorg/
broken udev (race condidion) worked-around by commands below
race condition when X server starts (xrandr before X socket is created can be worked around by a sleep 3 in /etc/X11/Xinit.d/01xrandr
Charging during sleep does not work in 2.6.3x kernels.

Another X work-around is a degrading to xorg-kdrive-1300. It seems to be far the best solution for now. The xorg-kdrive-1300 is an old driver, but it needs at least 4 times less memory. In this case open /etc/X11/xserver-common and comment out lines referring to Xorg.

Work-arounds of known problems of current snapshot

After each reboot and login, you have to execute:

# lo is not up for some reason after reboot
ifdown lo ; ifup lo
# USB is in broken UDC mode
rmmod g_file_storage g_ether pxa27x_udc 2>/dev/null
rmmod ohci-hcd 2>/dev/null
rmmod g_ether g_file_storage 2>/dev/null
rmmod pxa27x_udc 2>/dev/null
modprobe ohci-hcd
# Speech dispatcher blocks sound device
/etc/init.d/speech-dispatcher stop
# atd causes unexpected wakes and blocks RTC device
killall atd
# Just now, there is no keyboard way to turn light on. Disable off:
killall ipaq-sleep

If you are unable to switch to console or type commands, reboot to emergency system and remove or rename X server binary. After final reboot install needed X server.

iwmmxt specific problem (in iwmmxt builds, that are turned off now), which needs to be fixed: Locale cannot be generated (qemu iwmmxt support is broken), you have to generate them manually after activating swap (64MB causes OOM) calling proper post script from /usr/lib/opkg. Compiler fails on several packages with internal compiler error.

Experimental or incomplete patches and fixes affecting Sharp Zaurus SL-C3200 with Ångström

Fix default NAND flash partitioning defined by SL-C3200 boot ROM. Breaks SL-C3100, better patch is needed. Ångström bug.
Attempt to write kernel and X drivers for Colorgraphic Voyager CF VGA card (probably compatible with Iodata CFXGA). Work in progress, broken.

Here are miscellaneous files used to work around some problems (if proper fix does not exist) or fine tune Ångström behavior.
