Guys,
I made a new image, 'wandboard-dual-squeezelite-20130220.img.gz'
(http://www.vacuumtube.org.uk/downloads/wandboard-dual-squeezelite-20130220.img.gz),
to fix a couple of issues.
1. I doubt I will have time to look at this until the weekend and while
I know how it is supposed to work in a traditional initramfs, tempfs and
udev setup, don't know how it is supposed to work using uboot without an
initramfs. Basically prior to the mount of the rootfs the platform
specific device nodes are not being created. It's fine when the rootfs
is mounted, udev will create the /dev entries from that point onwards.
So anyway, I tar'd the /dev from the original wandboard image (after
boot) and untar'd to my image. So now the nodes are there for the
default on board sound devices. (Previously squeezelite -l wouldn't have
shown the devices and you wouldn't have been able to use them.)
2. Added the udev imx specific config. (/etc/udev/rules.d/10-imx.rules)
3. Added RT and memory locking for the audio group, which the ubuntu
user does belong to. (/etc/security/limits.d/99-audio.conf)
4. Recompiled brcm_patchram_plus, the broadcom bluetooth firmware
loader. (Although it was statically compiled sf, it wouldn't run on hf.)
5. Added the cmd line to /etc/rc.local to load the bluetooth firmware
and init the device. (Currently commented out with a #.)
Code:
--------------------
# /usr/local/sbin/brcm_patchram_plus --timeout=6.0 --patchram
/lib/firmware/brcm/bcm4329.hcd --baudrate 921600 --use_baudrate_for_download
/dev/ttymxc2 && hciattach /dev/ttymxc2 any 921600 &
--------------------
6. wlan0 should be there now as well if you iwlist. (It wasn't before.)
NB. Only potential issue is that it doesn't always cleanly reboot. After
sudo reboot (or shutdown -r now) you might need to hit the reset button
on the board to get it to boot again. I will look into this when I get a
chance.
