Hello NVIDIA experts, I would like to ask a question : in Jetson Orin JetPack 6.0, can any GPIO be used as UART? For example, the J55 pin — in the Pinmux_Config_Template there doesn’t seem to be a UART option for it, as shown in the picture below.

Hi wpceswpces,

Are you using the devkit or custom board for AGX Orin?

Please refer to the design guide for the available pins for UART.

If there’s no option for UART in pinmux spreadsheet, then it can not be used for UART.
In your case, GPIO32 can only be used as GPIO.
