I'v send a can_fd frame with 5Mbps rate in data field successful, but when i set the bit rate to be 8M(source clock=40MHz, bit time=5Tq: EPRESDIV = 0, ERJW = 0, EPROPSEG =1/0, EPSEG1 =0/1, EPSEG2 = 1, TDCOFF=3 ) I recieved a error frame in the CANoe 9.0.
first,I wander whether the maximum rate is 8Mbps? And i want to know how to set the register to send a can_fd frame with 8Mpbs？？
I still feel confused with the Transceiver delay compensation，is there someone can explain it clearly？
Looking forward to your reply！
You did not specify the MCU, assume you have MPC5748G.
The shortest configurable bit time for data phase is 8 time quanta.
Thus with a CAN_PE clock frequency of 40MHz the max bit rate in the data phase is 5 Mbit/s.
If you need more, you must use higher CAN_PE clock.
Also be sure the transceiver is able to run on such high rates.
the SSP was discussed e.g. here https://community.nxp.com/thread/450098
