Hi team.
How should I use DMA?
The DMA I configured was debugged normally, but the full speed operation was abnormal.
basic register to configurate.
For example:
1) initialze uart
2) enable uart dma request (key point)
3) config DMAMUX
4) config DMA
5) enable DMA (key point)
......
Thanks

Hi @DY_Liu
Chapter 14.4 of the S32K3xx MCU Family - Reference Manual provides instructions for initializing the DMA channel MUX.
You can also take a look into this DMA with UART example with the S32K344 in this community post:
I hope you find this helpful!

Hi @DY_Liu,
Could you give us more details about the error? What is the problem if the delay is not set? This is so we can reproduce the example to see if the behavior persists.
Best regards,
Julián.
