Bumping this thread with the news that my GPS unit and Pandaboard both arrived yesterday. At this point I have it booting android, have added drivers so its not bogging the CPU trying to render the graphics, added bluetooth, wifi, and FM drivers. I plugged the GPS in and it recognized it and loaded the driver. The resolution on the touchscreen is not bad and the colors look pretty good, however the touch function doesn't work. It also seems that something triggers a change in voltage, either the lilliput trying to go to power save or whatever and it seems to kill the HDMI link between them and the board goes to sleep. If I tap a key on the keyboard it wakes up but within 1 second is sleeping again, so I need to figure out how to enable the dvi-d port which is still an hdmi connector on the pandaboard, but you just get a hdmi-dvi cable or adapter (which I am using anyway since the monitor is DVI).
Its so awesome to be at this point finally. I have been dreaming up a carPC for two years and I am so happy to have left the VIA nano itx board idea behind. It will be a challenge, but things are going far smoother than I thought they might. (most of the hold up I ran into were not problems so much as me wasting time).
Next up I will try to enable the DVI-D and dig up the place where I read about getting the lilliput to work with the pandaboard.
