Hi, can you help me handle the data transfer issue with the CAN port under the CANFD function?
Firstly, import the MTTCAN module and set the CAN working mode and baud rate parameters
Secondly, using the Canfd testing tool for testing, the baud rates of 125k, 250k, 500k, and 1M were all normal, but when testing 10k, there were 4 messages received and they could not be received.
The kernel also printed an error message as follows, with all kernel information in the attachment：
[ 2137.311136] mttcan c310000.mttcan can0: Stuff Error Detected
[ 2137.311367] mttcan_poll_ir: 8 callbacks suppressed
