I am new to the i.MX6 community and trying to get Linux working on my new i.MX6Q SABRE for Smart Devices board.

After copying the boot-loader, kernel and root file system image on the SD card and rebooting the board for further testing..
it could not initialize the display... even though we could hear music files being played but nothing was visible on the LCD display..
the bootargs used were:


setenv loadaddr 0x10800000

setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'

setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 2;mmc read ${loadaddr} 0x800 0x2000;bootm'

setenv bootcmd 'run bootcmd_mmc'


any kind of help would be really appreciable.

Thanks before
