Hi,
I'm trying to get DVI output with XGA resolution.
I added XGA code to arch/arm/plat-omap/display.c in SDK_1.0.2 kernel. As per instruction here: http://wiki.davincidsp.com/index.php?title=Adding_new_DVI_resolutions
Entered this into console:
echo DVI > /sys/class/display_control/omap_disp_control/ch0_output
echo XGA > /sys/class/display_control/omap_disp_control/ch0_mode
I got the output to the external display. The display sees the mode as being 1024x768 70Hz, but I only see the picture (blue screen that is) occupying roughly one half of the screen -- it reaches about the half of the screen from left to right, and doesn't reach to the bottom.
My assumption is that the frambuffer resolution is not set correctly. I tried issuing fbset command, that is part of the busybox
fbset -fb /dev/fb0 -xres 1024 -yres 768
No change. When I issue it with no arguments, it tells me
mode "480x640-145"
...
Can anyone give me a hint on what's happening here and how I get things to work full screen with XGA.
Thanks!
