What Gumstix motherboard are you using? Verdex, Connex or Basix?
If you are using a Verdex motherboard, and a 16 bit display, you'll need
to set the pixel format to 16 bit:
I used the following to do that:
pxaregs LCCR3_PDFOR 0
pxaregs LCCR4_PAL_FOR 0
You'll need my patched version pxaregs:
Take a look at:
Specifically LCCR3_PDFOR and LCCR4_PAL_FOR.
For more info on setting up the pixel format.
