HDMI doesn't work on rock64

I use a rock64 board (Rockchip RK3328 Quad-Core SOC with Mali 450MP2)

HDMI doesn't work with any Kernel except the Kernel 4.4 from Rockchip (it also doesn't work with xorg) i tried out all kernel configs from rockchip and ayufan always same error:
[ 4.030085] printk: console [ttyS2] enabled

With Kernel 4.4 from Rockchip (ayufan) HDMI works:

I boot with extlinux.conf: The kernel starts only without console bootparameter: When i insert console=tty0 as boot paramter the kernel dont start.

Does anyone know what the problem could be.
Thank you in advance for your help
