Hi All ,

I use pre-build image : core-image-sato-sdk-imx6qsabresd-20150303160855.rootfs.sdcard on iMX6QSabreSD. I stop the u - boot and modify mmcargs ( editenv mmcargs ) to add this :

video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24

to enable the HDMI video.

After reboot , the Kernel hangs. If I remove the above modification , the board will boot but no HDMI video.

 

Anyone knows how to fix it ?

 

P.S. The link for pre-build image is :
