Hello!
Which Uart port of AGX Xavier module can print log directly when power on?Thank you!

hello Username1,

please access Xavier Developer Kit User Guide from download center,
you may setup connection with micro-usb on J501 to access the UART console.
the baudrate settings is 115200/8n1 by default, you may enable picocom or minicom to communicate with Xavier via ttyUSB.
thanks

Hello JerryChang

 we don't want to use the J501,only use the uartc as the debug port to print log.How to configure the software?

hello Username1,

please also refer to Xavier Product Design Guide, you could check [Table 13-10] for the UART pin description.
you can still using communication tools to talk with Xavier.
thanks
