Porting/Kernel
[edit] Upstream kernel with Maemo 5
1. Kernel patches from https://github.com/pali/linux-n900
2. CSSU-Devel from http://talk.maemo.org/showthread.php?t=84292
3. BME-Replacement from http://talk.maemo.org/showthread.php?t=93183
4. Fixup for wifi firmware:
mkdir -p /lib/firmware/ti-connectivity ln -s ../wl1251-fw.bin /lib/firmware/ti-connectivity/wl1251-fw.bin ln -s ../wl1251-nvs.bin /lib/firmware/ti-connectivity/wl1251-nvs.bin
5. Fixup for Dialer application (rtcom-call-ui):
Create new file /etc/event.d/userspace-fixes with content:
start on started hildon-desktop
service
console none
script
if ! hal-device /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev_input 2> /dev/null; then
hal-device --add /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev_input < /dev/null
hal-set-property --udi /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev_input --key input.jack.type --strlist-pre "a"
hal-set-property --udi /org/freedesktop/Hal/devices/platform_soc_audio_logicaldev_input --key input.jack.type --strlist-rem "a"
fi
end script
