That's great so what can I do to help with the latest rock64 kernel 5.4?
Should I get a setup with rock64 plugged into a monitor and then compare the boot info from Armbian_19.11.3_Rock64_buster_current_5.3.11 (working) vs Armbian_19.11.6_Rock64_buster_current_5.4.y (broken)
If this is a good starting point then happy to assist...
