Enable UART1

[niyas2]

Im using jetson orin nano jetpack 6 i want to enable UART1 on the 40 pin header ,How is possible ?

nvidia@ubuntu:/proc/device-tree$ ls /dev/ttyTHS*
/dev/ttyTHS1 /dev/ttyTHS2
nvidia@ubuntu:/proc/device-tree$
only enable these two no found the THS0 and in the 40 pin expansion header is

                  3.3V (  1) .. (  2) 5V                           
                i2c8 (  3) .. (  4) 5V                            
                 i2c8 (  5) .. (  6) GND                         
              unused (  7) .. (  8) uarta                   
                GND (  9) .. ( 10) uarta

Hi niyas2,

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

I think it has been enabled by default and you can simply use it through /dev/ttyTHS1.

Please try shorting PIN8/PIN10 of 40-pins header and run the following command to verify.

$ sudo su
# stty -F /dev/ttyTHS1 115200 raw -echo
# cat /dev/ttyTHS1 &
# echo "test" > /dev/ttyTHS1
