Hello,
I have the OSELAS.BSP-Pengutronix-Mini2440-2012.06.0 installed on my
Micro2440. The display has TD035STED4 the designation. Everything works,
only the display is blank. I have chosen in the kernelconfig TDO35S support.
The touch screen works and I can also turn on the backlight. I use fbtest
but nothing is displayed. Is the shell at all on the display?
Many thanks
Hans Sorge

The screen being completely blank despite fbtest is indeed a bit
strange, if you have passed the correct kernel args for your lcd.
The getty is not on the screen as far as i know. The qt4/qml demos
should show you something there, for a first test.
