Hello Muri,
Iam facing the same issue with i.MX6 Sabrelite platform. Below are the environment variables that I have issued by interuupting the booting for the first time.
MX6Q SABRELITE U-Boot > setenv bootcmd 'run bootargs; mmc dev 1;mmc read ${loadaddr} 0x800 0x2000;bootm'
MX6Q SABRELITE U-Boot > setenv bootargs 'console=ttymxc0,115200 root=/dev/mmcblk0p1 rootwait rw video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi'
