Hi, I’m using Xavier-nx. I need to use all of supported UART interfaces for our application. I can see that uart : /dev/ttyTCU0 is used for debug. I want to change its function to normal UART, because I witness several abnormal behavior when communicating to that port: I can’t not change the baud…

This isn’t answering anything, but I want to throw out something about this situation (it might be useful to clarify what it is you are working with). Each device special file name is generated by a driver. Those drivers must exist in the bootloader. Each ttyS# actually has a complementary ttyTHS# …

Xavier-nx: How to change UART port: /dev/ttyTCU0 as normal UART function

We use Jetpack 5.0.2 and it is a custom board.
I know combined UART is not recommended to disable, but in our application, we need 3 normal UART, and 2 other ports are in used.
I follow some related post like: [Jetson Xavier NX] UART Tune - #15 by JerryChang, but the device can’t be booted.
I just want to send/receive data through that port as normal UART, please give us some instructions.
Thank you for your support
