I have a RockPi 4C+, and am trying to get my HiFiBerry AMP2 working, but am not having much luck. Do I need to compile my own kernel to get it to work? I haven't been able to find any good instructions anywhere on enabling my HiFiBerry on a non-RPi SBC platform.
I did find this DTS file [1], but I haven't had much luck with it, presumably because images are now running a 5.x kernel?
