Testing HDMI with Tinkerboard (and others RK3288)

If anyone has troubles with HDMI when using 5.x kernels, and has enough skills to recompile an armbian, give this a try : https://github.com/Miouyouyou/build

 

And then either answer here, or in the bug report : https://github.com/armbian/build/pull/1887
