I think the pin configuration is fine with this one. But this controller is disabled in the device tree
The actual serial port terminal can also be used（Can interact normally）, I don’t know where the problem lies? Please help me confirm
Hi 550399056,
Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?
It seems you are configuring the Tegra Combined UART, which is used for debug purpose only.
It will output the debug message from several firmware and it can not be used as normal UART for other peripherals.
Please use the other 2 UART interfaces available on Orin Nano for your custom use case.
