Anyways it is becoming more strange now. I did boot the old Pyra
from eMMC. With an 4.19.3 kernel. And it failed as well. But the
4.20-rc5 boots there.
Now I have different boot logs to compare:
4.19.3 on old Pyra fails
4.19.4 on new Pyra boots
4.20-rc5 on new Pyra fails
4.20-rc5 on old Pyra boots
What is the logic behind?
At least I can test the 4.20-rc5 on the old Pyra and try to search for panel enable calls.
Well, it does not try to enable the panel.
BR and thanks,
