Since Armbian moved to the official Rockchip kernel, camera support should work with their new ISP1 driver. I built an image with the needed drivers but unfortunately it doesn't boot anymore...
A boot log with the compiled drivers can be seen here (kernel config is attached to this post):
What I tried so far:
-disable all patches which have something todo with MIPI system and adjust defconfig
-try to compile kernel with isp1 as module (doesn't compile)
-the 'asus way
