This topic belongs in the Jetson category, I have moved it over for you.

Hi liusu,

Your board seems custom board, please contact your vendor for TXD/RXD/GND of UART console.

For the devkit of Jetson Nano, you could refer to the following instruction to setup serial console.
Jetson Nano Style - Serial Console - JetsonHacks

Thank you
