Hi @semiconductor_user

DMA support is only for RXFIFO and because enhanced RXFIFO is only on FlexCAN0, DMA and CANFD usage is not possible on other FlexCAN modules, just classical CAN+legacy RXFIFO+DMA functionality is available.

You can refer to these community posts for some reference in DMA and CAN configuration:
