I import the CAN demo 'FlexCAN_lp_Example_S32K344' which work mode is loop-back, it works on EVB S32K3X4EVB-Q257 47827 PCB . However, after I changed the work mode from loop-back to 'Normal mode or user mode', and configured the flexCAN0 Rx/Tx, and add the Siul2_Port instance, build it and run, it could not send any message out, even I tried to test the waveform on PT275(on EVB, CAN0 Tx).
Could you please figure out the error place and teach me how to deal with it? Thanks!
could below thread be useful for you?
There is secure CAN transceiver on the board, TJA1153, which is not configured by default and it does not allow the MCU to communicate with the CAN bus. So a config must be done first.
