[Gumstix-users] Problems with DLP Pico Projector Kit

[Michael F. <awa...@gm...>]

Hello All,

I recently purchased some gumstix equipment (an Overo Fire COM and Tobi
expansion board) and a Texas Instruments DLP Pico Projector Development
kit, which I had hoped to use as a display.  After a great deal of
searching for the correct frame buffer configuration all I've managed to
accomplish was to cause the screen to flicker with horizontal bars. 
I've tried every DVI setup that has been claimed to work, and plenty
that haven't, so I can only conclude I'm doing something else wrong. 
Below is my current boot environment, and I am using the Angstrom
2010.7-test-20110309 overo ttyS2 version.

Thanks in advance,

Mike Fadden
