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 before 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, 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. Be prepared that your first boot will not have
working touchscreen or keyboard! Hopefully there is an
emergency system. You can mount the hda1
partition and fix it.
You have two chances to fix: Install ancient but memory conservative
xorg-kdrive-1300 or fix Xorg configuration (bare Xorg requires 8.5 MB of
memory, kdrive's Xfbdev 1.2 MB).
- Install xorg-kdrive-1300: Edit /etc/X11/xserver-common and comment
out three lines checking for Xorg. System will boot to console and you
will be able to install xorg-kdrive-1300.
- Fix Xorg configuration (not tested with the last Xorg!): Copy xorg
setting files and apply patch from
ftp://ftp.penguin.cz/pub/users/utx/zaurus/files/xserver-xorg/.
Comment out all xmodmap calls in all /etc/X11/Xinit.d
scripts. One coordinate of pointer my be 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
In both cases I recommend to remove default.xmodmap and
xmodmap-* from /etc/X11/xmodmap/. They are
hardcored in gpe-dm and may break your keyboad.
- 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 (they are not
part of the default image).
If
you want to get my software experience, install matchbox2
package and its dependencies. You will login to Matchbox 2. You can
configure it in /etc/matchbox2/defaults.
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
# You can do this if you connect Bluetooth and want auto-configuration of BNEP networking:
ifdown bnep0 ; ifup bnep0
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.
Emergency system
Emergency Sharp 2.4 system can be booted by simultaneous pressing of
D and B keys during reboot or during pressing of reset button and
turning on. You will get a minimalistic emergency system. You can mount
your HDD by mount /dev/hda1 /mnt and then fix problems. There
is vi editor available.
If you are unable to switch to console or type commands, reboot to
emergency system and rename X server binaries. You will then boot to
console. You can also edit /etc/inittab and add debugging
commands there.
Experimental or incomplete patches and fixes affecting Sharp Zaurus SL-C3200 with Ångström
Here are miscellaneous
files used to work around some problems (if proper fix does not
exist) or fine tune Ångström behavior.
If
you want to get my software experience, install matchbox2
package and its dependencies. You will login to Matchbox 2. You can
configure it in /etc/matchbox2/defaults.
