issues with connecting pixhawk through serial port
I am trying to connect pixhawk 2.4.8 with Jetson Xavier NX serial port ttyTHS1.
I have ensured the connections are proper and referred through serial port issue .
I disabled the nvgtty
$ systemctl stop nvgetty
$ systemctl disable nvgetty
and restarted NX, i am seeing image of BOOTLOADER SHELL like display.
If i disconnect port and connect once after it gets booted, Its not showing any serial connection info.
sudo stty -F /dev/ttyS1 -a
I am new to Jetson, used to use only raspberryPI ,
Can somebody share the solution or at least guide me the possible ways to utilize the Serial port .
could you please access NX Developer Kit User Guide for the J14 pin descriptions to review your pin connections. you should connect to pin-3 and pin-4 respectively for UART receive and send.
if you checking NX Product Design Guide, that’s general used for debug console.
please also refer to similar discussion thread, Topic 145106 to change debug console.
Thanks for your response @JerryChang
Actually, I have referred through the NX Product Design Guide
pins 8 and 10 are referring to UART port.
I have connected these pins respectively and checked with reversing as well.
but could’t get any response in the console for the specific port info :-(
Checked other visible ports also :-|
naga@naga:~$ sudo stty -F /dev/ttyTHS0 -a

FYI, the default baudrate setting is 115200/8n1.
Its working fine .
Thanks for your support :)
