My MX6Q board is basically based on SABRELITE platform.
The HDMI port works well with "1920x1080@60HZ",
with the following kernel cmd line:
setenv hdmiargs 'video=mxcfb0:dev=hdmi,1920x1080@60,if=RGB24,bpp=32'
However, if I change the hdmiargs to 1024x768:
setenv hdmiargs 'video=mxcfb0:dev=hdmi,1024x768@60,if=RGB24,bpp=32'
The HDMI resolution is 640x480
I try to add 1024x768 to mxc_cea_mode in mxc_edid.c, but I can't see anything in the screen. The terminal print these information every 3 or 4 seconds :
Display is GTF capable
mxc_hdmi mxc_hdmi: same edid
How can I set the HDMI support 1024x768?
