Hi,
I have created kodi gbm wrapper service which auto starts on boot. It works fine if my Marantz SR7011 AVR is already on when the EDGE V boots up. But if the AVR is turned on after the EDGE-V completely boots up, I don’t get display on kodi. I tried putting custom EDID
mkdir /lib/firmware/edid
cat /sys/class/drm/card0-HDMI-A-1/edid | sudo tee /lib/firmware/edid/1920x1080.bin
But It doesn’t work, I have looked up dmesg for any errors related to edid
dmesg | grep edid
There’s nothing related to EDID in dmesg
Also posting output of dmesg | grep drm :
