At least on the v1.1 board cec is functional: > Total for dwhdmi-rockchip device /dev/cec0: 1, Succeeded: 1, Failed: > 0, Warnings: 0 Peter, Thx for this. This is good news. I see 4 potential root causes why it not works for me: not mutual-exclusive: 1\my DTS has errors needed fix 2\my kernel config needs tweaking for cec on rk3568 3\my rock3 v1.31 hw needs some extra dt love (over yours v1.1) to get cec working 4\my bootloader passes hw to kernel in state that cec is non-functional May you pls send me via PM to piotr.oniszczuk@xxxxxxxxx yours kernel config & working for you dts? If i fail with 1/2/3 then i'll need go with yours booloader... lets try see is 1/2/3 with your dt and .config please?
