Peter, Here is what i done to verify my rock3-a HW: 1.download & burn on SD Radxa Ubuntu 2.boot and install v4l-utils 3.run cec-compliance -v -T. It fails with error -22 4.decompile Ubunntu DT. 5.Check what HDMITX_CEC_M hdmi uses. It was M0 6.Chenge to HDMITX_CEC_M1; compile dtb; install on sd 7.reboot. 8.cec-compliance -v -T gives all tests OK 9.cec-ctl --image-view-on -t0 turns-on my TV hope this proves my HW is ok?
