Android & 3.5" LCD (Gumstix Palo35) does not work #89

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Download & install the pre-built images on an Gumstix Overo Tide with 
Palo35, LCD.
2. Edit the boot.scr file to include lcd=35 instead of lcd=43
3. Boot the system

What is the expected output? What do you see instead?
The display should render. Instead, the display is garbled and you can make out 
what seems to be the colours of the unlock screen.

What version of the product are you using? On what operating system?
The latest build from: http://cumulus.gumstix.org/images/android/current/

Please provide any additional information below.
Any help would be greatly appreciated. I am able to get the stock Armstrong OS 
from Gumstix running on both the 4.3 and 3.5" LCD's (Palo43 and Palo35) 
respectively. But Android only seems to work on the 4.3" LCD, the 3.5" LCD does 
not display correctly.

I've already tried separate boards and it seems to be an issue with the display 
driver or settings used to initialize it.

The complete boot.scr:

setenv anddisplay 'vram=8M omapfb.mode=dvi:1024x768MR-16@60 
omapdss.def_disp=lcd43'
setenv andconsole 'console=ttyS2,115200n8 console=tty0 
androidboot.console=ttyS2'
setenv androot 'root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/init'
setenv andbootargs 'setenv bootargs mpurate=720 ${andconsole} ${androot} 
${anddisplay} no_console_suspend'

if test ${bootdelay} -ne 1; then
  echo "Setting boot delay to 1"
  setenv bootdelay 1
  saveenv
fi

setenv bootcmd 'mmc init; fatload mmc 0 ${loadaddr} uImage; run andbootargs; 
bootm ${loadaddr}'
boot

I also tried adding: setenv defaultdisplay lcd35 but the end result is the same.

This does work if you build from source instead of using prebuilt images from 
Gumstix.
