How to invoke flexcan event callback

[chris_010]

I use flexcan_1 of S32K312  to communicate with PCANpro，the communication seems well, mcu can receive and send data.  However, the callback function fails to work properly. What is the reason for this? Is there any need to register or monitor the callback function? No relevant APIs were found.

here are my code and configuration.

---- DMA is used for SPI，it does no matter with can.
