S32K3xx FlexCAN legacy and Enhanced RXFIFO DMA

[karmegancjk]

I am working on the S32K344 FlexCAN, and I have some questions while using FlexCAN. 

1. How is DMA actually working in S32K344, and how to use it?

2. How to integrate legacy FIFO with DMA and enhanced FIFO with DMA

3. Are there any consequences that will come while using DMA?

Hi,

I can simply recommend to first read a device Reference manual to learn DMA, DMAMUX and FlexCAN modules. Attached you can find presentation summarizing those module's functionality and give insight on RTD usage. Then you can refer to available RTD demos in S32DS or other posted on Community; https://community.nxp.com/t5/forums/recentpostspage/interaction-style/tkb/post-type/thread/board-id/...
