TC27x CAN FD FIFO

[_Julien_]

Hello,
Could you tell me if it is possible with a TC27x, as it is with CAN, to set a FIFO of message objects with CAN FD?
Thanks

Not directly, because the CAN_MOFCRn.MMC field only supports FIFO *or* CAN FD, but not both.

If you don't mind writing your own complex driver, you can reach most of the functionality of a FIFO by connecting MultiCAN Rx/Tx service requests to DMA.

That's what I had understood either FIFO or CAN FD.
Thanks for the confirmation and for the DMA tip!
