EDID-Decode returned "was Empty" .

The process to create an EDID file starts with EDID data. The only thing that I have is from dmesg boot images:
[ 3.875114] [drm] Initialized vc4 0.0.0 20140616 for soc:gpu on minor 0

And I am not sure that this is correct.

I re-installed the old original Kanux 4.3.3 (stretch) which does not have any problems but the dmesg images do not show any EDID images because it apparently does not use vc4-drm.
