Hi g_shilong,

Have you tried to use UART1(/dev/ttyTHS0) to communicate with your MCU?

To make a debug UART as normal UART.
It can be done with the following 2 parts.

  1. Disable combined UART
  2. Enable it as normal UART

You could refer to the following thread for this.
Repurpose Debug UART for 'normal' comms on Xavier NX - #6 by JerryChang

It could be done through modifying the device tree and related files,
but it has not been verified from us and we could not guarantee the performance with this use case.
