Hi,

RevPi Connect 4 support was added with Bullseye, thus won't work with Buster.

Hallo Frank,

Hi

Has the Con CAN overlay been enabled? There should be a line in /boot/config.txt of `dtoverlay=revpi-con-can` or check with `revpi-config status revpi-con-can`.

Enable overlay: revpi-config enable revpi-con-can
Disable overlay: revpi-config disable revpi-con-can

Hi

Has the correct overlay been loaded (dtoverlay=revpi-compact in /boot/config.txt)? Are there any errors in dmesg respective /var/log/kern.log?
