Hello everyone! I would like to have make an UART connection between Xavier and Pixhawk but that doesn’t work. The /dev folder on Xavier doesn’t contain seial0 which indicate if the connection is established. Any help will be welcomed. Thank you.
Here are some pictures illustrating the connections I made.

The Jetson uses different names for it’s UARTs: /dev/ttyTHS0, /dev/ttyTHS1 and so on.

HI @stephendade. Indeed I have these paths but I cannot have a connection through them.

Can you be more specific? - what commands have you tried and what error messages are you getting?
