Hi! You've got HDMI on Pine64-LTS working? Could you please share the
process / patches? I've tried CURRENT, STABLE and building my own image
from latest src and in the end it's always the same - HDMI stops working
right after EFI loader boots the kernel. Did you change dts in any way or
used some overlay? Thanks in advance
Tried on two different LCDs with 800x480 and 2560x1440 native resolutions
btw.
