7'' LCD not working on PandaBoard with Linaro 2.3.5

[fanchb]

Hello,
Thank you for your last feedback, Android is booting now and the LCD works fine. I don't know why we had the wrong boot.scr on the SD card since I used your command present in the Android_Images_Installation_on_Pandaboard file and the boot.tar.bz2 was including the right boot.scr, so it is a mistery for me.

I did not have to type reboot to make it boot, nor to change the resistor.

We will order new LCDs soon!

I have a few questions: apart from the bootagrs in the boot.scr which is different from the Linaro version, how different is your Android version from the Linaro 11.09 ? It is possible to easily isolate the changes, build required drivers if any, and bring them in most recent Linaro releases like 11.11 ?

2 differences:
1. boot.scr
2. uImage
uImage file is binary of linux kernel. you may check with the source code for difference between linaro 11.09 and our customzied version. In a short word, we add 3 drivers into this linaro kernel: backlight, touchscreen and RTC.

Could you please let me know in which folder I can expect to find the right sources: Beada20111116 ?

Thank you!

Woud you mind to give us the exact number of the Linaro build you are using for Release 11.09 ? It will help us to look at code differences. So far we have been comparing source code between Beada20111116 and build 3.0-2011.09 of the Linaro distribution. We have found many modifications in Drivers\Input\mouse we were not expecting since you were only mentioning 3 drivers, not including the mouse driver.

Thank you!

2. Beada modified kernel source code:
