I have been scouring the internet looking for a simple example or advice on using the Jetson TX2’s UART port. I am using a Jetson with the connecttech Orbitty Carrier board. I have notice that two UART ports are piped out to the expansion header as noted on pages 11, 12 of the manual: http://www.connecttech.com/pdf/CTIM-ASG003_Manual.pdf They even mention that these should show up as /dev/ttyS0 and /dev/ttyTHS2. I can see both of these devices but cannot figure out how to interface with the UART port.
I have tried echoing in one terminal and catting in another. I have tried screen. Is there a simple tutorial or setup guide on how to get UART working on the TX2?
