I have been trying to connect to my Jetson Xavier NX connected to the AverMedia EN715 companion board via a UART connection. For this I have connect the board to my computer via the FTDI TTL-232R-3V3 USB to serial cable. I have configured minicom to use the /dev/ttyUSB0 port.
When I connect the Jetson to my computer via this cable and power it on, I can see the boot sequence through minicom. It boots successfully until it gets to the part where it asks for a password. Here I try and enter a password through my computer keyboard, but this does not get passed through. In fact none of my keystrokes do.
Does anyone know why this might be? Could this be a minicom issue or is there an issue with my connection? Everything looks right and the fact that I can see that the jetson is booting leads me to believe at least part of the connection must be working.
Thanks for your help!
