Re: How to get framebuffer output on x50V

well fisherss, have you added to your image on the site ?
  i'll try to contact the people from pepper between...

The guy who has got framebuffer output on x50V told me some details today :)

To make you kernel image support x50v framebuffer, use the attached
file to replace your aximx30_lcd.c and then recompile you kernel, you
should get some thing on the LCD.

NOTE: Set your x50v to mirror mode under WINCE before loading the
kernel image.
