We are using S32K312 chip to configure UART driver. The configuration mode is UART+DMA. The configuration process is as follows:
uart config:
dma config
uart and dma Initializes
Please tell me what is wrong with the configuration process and why TX cannot send data.
THANKS
please take a look at this post.

hanks for your reply. Now we have encountered new problems. The baud rate we designed is 115200. After the device is powered on, a normal frame will be printed, but garbled codes will appear again. I have checked the initialization process of the routine you provided and it is the same as our call here, please help to guide, thank you.
