I'm trying to set up my tinker board 2s so I can control my tinker using my smart TV remote controller, I managed to control my tv from tinker using cec-ctl but now I want to handle remote control key events from my tinker board, but all the solutions are giving that I should use cec-client which is not working as it should on my tinker.
When I try to run this command it returns none
cec-client -l
Found devices: NONE
I want to know how I could configure cec-client on my device.
