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

# D: 26.316 MHz, H: 52.214 kHz, V: 80.206 Hz

endmode
