We are trying to use the /dev/ttyTHS0 UART port on a Jetson Xavier to communicate with an external microcontroller. Following the post here as a guide we have modified the device tree to remove the default debug console on the UART port. This was done by removing bootargs =“console=ttyTCU0,115200” f…

hello user59604,

Xavier series is using combined UART, you need to disable Xavier combined uart TCU for general UART communication.
please check Topic 182785 to disable combined uart and assign the correct uart port for the logs.
thanks
