Hi @Hansoncc
It seems like that the MRAA does not support PI4 currently.

There's a PR for the initial PI4 boards open here. You would have to build MRAA from source to try it though, and as far as I remember it was for the first revision of the PI4 so it might not work if you have a newer one.

It's merged so please confirm this issue is still present,
