MPC57xx: Configuring and
Using the eDMA Controller

Is this application notes totally applicable for S32K322 also?

Re: Is RTD 3.0.0 compatible DMA for FlexCAN

Hi @PetrS what is the difference b/w these both functions
FlexCAN_Ip_RxFifo(INST_FLEXCAN_0,&recvBuff2);

FlexCAN_Ip_Receive(INST_FLEXCAN_0, RX_MB_IDX, &rxData, false);

and when I was reading the k3 reference manual it was not that much clear to me, Can you provide any simple document for understand the CAN DMA , message buffer usage, CAN ID filtering, CAN Interrupts, etc.

Hi,

yes it is. If you have some issue please share your simplified project, or refer to posted demos, e.g.
