Hi,
I am getting SYNC LOSTerror on OMAP development board ( LDP ), this happens when I enable mirroring by a command
#echo 1 > /sys/class/graphics/fb0/mirror
In brief, recently I ported board related funtions to support both LCD and TV displays on Omap LDP, mirroring works on TV but not LCD. Attached log gives more details.
Any inputs are appreciated.
Regards,
Subbu
