What's the difference between UART2 and UART3_DEBUG

It shows in DG that AGX provides UART2 and UART3_DEBUG for debug purposes,there is just one debug port on my board,so i need to know what’s the difference between them and then decide which one to use.

hello Username1,

you might refer to Xavier Product Design Guide , check [Figure 14-1 JTAG and UART Debug Connections] for the details.
thanks
