Hi



I have Balloon 3 with working touchscreen and backlight but frustratingly no
display output.



Nothing is displayed during startup, piping text to tty0 or when using
Xfbdev or similar.

Does anyone have a known good code base for a working Balloon3 with Toppoly
display which they can direct me to or any framebuffer/Toppoly config tips.



Any help appreciated,

Many thanks,

Jim





I'm using a 2.6.25.2, built as detailed in
http://www.balloonboard.org/balloonwiki/SoftwareBuilding

Toppoly display: TD035STEE1

The fbset details correspond to the pxa balloon3_lcd_mode settings

mode "480x640-80"
  # D: 26.316 MHz, H: 52.214 kHz, V: 80.206 Hz
