I wanted to use both the UART Ports available on the Jetson Nano (the one on J44 and the one on J41).
The UART Port on J41 works fine for bidirectional communication.
However the UART Port on J44 is not working to receive data on the Jetson from an external source.
When I use the pyserial library to establish communication, I get an error related to device already being possibly busy.
I think this is due to the agetty process running on ttyS0. But I am unable to kill this process.
I believe I need to disable the Serial Debug Console via Jetpack Installation for the Nano before flashing the Nano.
But I am not aware of the changes that need to be made after installation before flashing the Nano.
Can someone please advise what changes have to be done?
