Hi all,
I use an Intel NUC8i3BEH, which has HDMI CEC and an internal CEC header, which typically is used for the Pulse Eight CEC adapter. I plan to use CEC for a project (not the Pulse Eight adapter, I'm planning CEC communication with an Arduino). I use debian bookworm 64bit, and I installed v4l-utils and cec-utils, but any cec-related command from these packages yields "/dev/cec0 no file or device found". dmesg does not list anything with cec in it. So I was wondering if I need to activate some kernel module or anything else. I've searched the internet half a day long, but documentation is surprisingly scarce.
Btw.: I tried all kind of variations in the BIOS. Intel doc's say: To use the internal header, you need to disable HDMI CEC in the BIOS, did this, but also tried with HDMI CEC enabled, to see if the HDMI port CEC registers somehow.
Somewhat at a loss right now, any help appreciated!
