Hi Marc,
Do you know there is some easy ways for us to test CAN performance? I tested it before by hardcode the driver, it's not a good way. Thanks a lot!
Best Regards,
Joakim Zhang

I usually use cansequence to test TX and RX performance independent of
each other, or canfdtest for a full duplex test.
cansequence sends CAN frames as fast as possible, while canfdtest has
some sleeps to properly interlace the RX and TX path.
regards,
Marc
