Why does it not work when uart uses DMA

[mgdsun2000]

My project works normally under S32K312, and uart uses DMA to send and receive. However, when the project was migrated to S32K314, it was found that DMA could not work. Its configuration is consistent with S32K312. What are the differences in DMA configurations between the two chips?

You haven't described the issue but there are differences in  DMAMUX map.
