Hello, we use Jetson Nano as the mission computer for our project. We use Pixhawk 2.4.8, TFmini LiDar and a ultrasonic distance measurement sensor. All of them uses UART to communucate with Jetson Nano.
My question is how many UART does the Jetson Nano has? Where is the physical connections for the UARTs
Are you using the devkit or custom board for Jetson Nano?
If you are using the devkit, there are 3 UARTs for Jetson Nano, one is used for debug message output, one on M.2 Key, one on 40-pin header.
We are using the devkit B01. We need to disable the button-header debug message output. How can we disable it?
Do you mean that you want to disable the debug UART for Jetson Nano?

It would cause you hard to debug the issue in the future.
Please try the following steps
- disable console over UART

- set ODMDATA to 0x14000
