I am connecting telemetry 1 port of pixhawk with Xavier uart pins 8 and 10. I set the baud rate of 115200 on both side but still cant able to read parameter on Xavier.
Did you first disable the serial console? If not, then probably something else is getting in the way. Which “
/dev” file do you use? If that file has a group of “
dialout” when viewed with “
ls -l /dev/tty...filename...”, then it is probably free to use as you see fit, but if it has group “
tty”, then it guarantees failure as it is still running as a serial console.
Also, make sure the pixhawk is using 3.3V logic levels.
