Hi everyone! I try to configure the candlelight-FD on ubuntu 22.04 with 6.5.0-26-generic kernel and I still get the error no-acknowledgement-on-tx when I'm using the command to configure the interface from the original website (sudo ip link set can0 up type can bitrate 200000 dbitrate 2000000 fd on).
If you don't get an ACK, you're effectively alone on the bus or using the wrong bit rate. Note this is not a candlelight problem, I think you'll find better help in a CAR hacker forum.
