Enhanced Rx FIFO feature in FlexCAN CANFD mode in S32K116

[jayashreepasane]

In S32K116, CANFD module says that RX FIFO cannot be used in FD mode. In just next line reference manual says that to enable Rx FIFO in FD mode, Enhanced Rx FiFO feature must be enabled.

I want to understand what is Enhanced Rx FIFO and how to enable it?

Hi,

S32K1xx FlexCAN does not offer Enhanced RX FIFO, so still is valid that Rx FIFO cannot be used in CAN FD mode.

A note about Enhanced RX FIFO does not exist in latest RM rev11.

Can the Rx FIFO work if payload is 8 bytes with CANFD ?
