Tutorial A - FD off

(Linux) $ sudo ip link set can0 up type can bitrate 1000000 restart-ms 1000 fd off
(RaspPi) $ sudo ip link set can0 up type can bitrate 1000000 restart-ms 1000 fd off
(RaspPi) $ candump can0
(Linux) $ cangen can0 -g 500

Tutorial B - FD on

(Linux) $ sudo ip link set can0 down $ sudo ip link set can0 up type can bitrate 1000000 dbitrate 2000000 restart-ms 1000 fd on
