Contact ASUS. This is their duty and expense to cover. Or yours.

 

Our build system will save you few weeks so welcome to make a donation. It is very expensive to keep it maintained.

When you are done, by you or by people you will be hiring to solve this problem for you, share a patch with others. Armbian does not need this to function. You do.

I've had trouble supporting this board, a lot of "s" variant boards in particular do not like to boot using mainline ATF. The only reason there are mainline images is because I created a device tree/got a supply driver/etc.  The DP over type C should work provided the device tree is updated, you can find examples on several other RK3399 boards we support.
