My Pandaboard powered Android CarPC for my 2002 VW Jetta [WIP]s
Update Oct. 16, 2011: The pandaboard was waiting for me when I got home from work Friday. So far it boots into android and I can see through hyper terminal that it sees and loads drivers for wifi, GPS, FM, and Bluetooth but not the touch screen. I'll have to sideloads apps to test things because the build is not necessarily meant for this use. I had to enter alternate boot args (mentioned in the release notes) in the bootloader to boot because it would error, and add graphics drivers and wireless drivers (both well documented) to get things running smoothly because without acceleration graphics were quadrupling boot time.
I have another problem where I get errors about the HDMI port followed by the board and touch screen going to sleep, but I intend to use the dvi port once I can enable it anyway.
Things are moving more quickly so far than expected. I expect it will slow down as I get into app testing.
I have ordered a Pandaboard, have a black-box N from Bybyte, a USB GPS unit, and a 629GL DVI Lilliput touchscreen.
My intention is to replace the stock in-dash stereo, have an accessible aux audio jack, if its possible to use a USB cd-rom with the pandaboard (I think I read that it is) I intent to mount a drive where the retractable cup holder currently is in the jetta, have extra USB ports provided by a powered hub, obviously add GPS, and if necessary get a FM tuner to work with it (its currently unclear to me if the pandaboard handles FM). Once I have all the hardware set up and android installed I will try to get the GPS working, find or create a suitable dashboard style control system, and then deal with converting the power and audio to match the car.
The board and GPS unit are in transit to my location and I have installed the Lilliput monitor in the black-box.
I have confirmed that the Lilliput is compatible with the pandaboard/android, but not the GPS. It was suggested to me that the GPS should work with android however.
I will chronicle my trials and tribulations throughout the process of setting up and then installing the system here.
Please chime in with any questions, tips or suggestions.
My first batch of questions are about power: I'll need a 12V supply for the lilliput and 5V for both the pandaboard and the powered hub. I read that the pandaboard can be configured for automatic startup at power-on, so a setup which will accomodate that would be a plus. Would it be possible to use the current stock stereo power supply setup to pull 5V and 12V lines, and would it be expected to supply enough current? I imagine I'll need it to be at 5v with around 3-4amps for the hub and about the same for the pandaboard, I can get a better idea when I have it in my hands and can monitor usage with various applications and accessories plugged in. I figured I could use two of these: http://store.mp3car.com/Carnetix_CNX..._p/pwr-016.htm for the hub and panda but they might be cutting it close since the pandaboard specs recommend more than 3Amp.
I also figure I could use a p1900, p2140, or opus 80 but that seems costly and perhaps overkill for this - unless I want ignition power on/off.
