The receiving interrupt of S32K344 can cannot be triggered

Why is the Rx FIFO Transfer Type option invalid in my S32DS3.5 (RTD3.0.0) project, but it is valid and optional in the S32DS3.4 (RTD2.0.0) project downloaded from the NXP community

Hi,

if you have CAN FD enabled then only Enhanced RXFIFO can be used. This is only available on FlexCAN0, so that's why option for transfer type is greyed.
If you disable CAN FD and enable Legacy RxFIFO then you will have this option accessible.

But，my Flexcan_0 can not do it too.

Hi,

I see transfer type can be selected, but here an error is different. 
When Legacy FIFO is enabled then CAN FD cannot be used.
