Greetings All,

I am trying to connect LCD with P1022DS via DVI port, I have also configured CONFIG_FB_FSL_DIU and using following boot parameters, but I can't see anything on the LCD not even the Linux Logo (I have configured it as well in the kernel) instead I only see on the LCD "No Signal from the Source". My LCD is working on another board. The "Freescale DIU Driver" is also loading during boot, but I got the same message on LCD of "No Signal".

diufb=15M video=fslfb:800x480M-32 at 72, monitor=0

Also tried fslfb:800x600
and monitor=1 and without monitor.

Any patch I am missing or anything else ?

Best Regards
