I add this in config file but nothing changed.
extlinux.conf:
LABEL LibreELEC
LINUX /KERNEL
FDT /sun8i-h3-orangepi-pc.dtb
APPEND boot=UUID=2103-3042 disk=UUID=f9d49f22-9a8c-4afe-9759-7d245eaf6197 console=ttyS0,115200 drm.edid_firmware=edid/1920x1080.bin
It seems to be a problem with the HDMI output. Are there any other options?
I changed sd card, power supply and HDMI cable, nothing helps.
