Jetson-Nano-Developer-Kit-A02 Uarts Communication

Hello EveryBody,
I have a Jetson-Nano-Developer-Kit-A02 …
Based DevKit Schematic pdf ,it has 2 port header(J-44 and J-41) for UART2(Debug) and Uart1 !!
For J-44 ,It is not in the document but it was printed at the bottom of the
Board.
1-GND
2-RTS
3-NC
4-RXD—>UART-2(DEBUG)
5-TXD—>UART-2(DEBUG)
6-CTS
and for J-41


I have a question!!
I have configured the baud rate as 115200 for 2 port UART2 and UART1 then open there,but i faced with login OS terminal in both !!

What can i use UART1 to connect to PC?
Can someone help me??!!
Thanks

@hhami.2040,

Do you need connect 2 UARTs from J41 and J44 each other?
Then you may refer these two links:


The device name of UART1 on J41 is /dev/ttyTHS1.
