Pinout ttyS1 UART

Stephen Roberts · September 2016

Hello

I have installed ubilinux using the instructions on Intel's website for the robotics development kit. The depth camera is all working correctly.

I am now trying to use the TX and RX pins on the pinout for serial communication. However ttyS1 does not show up when running dmesg, I only get ttyS0 and ttyS4. The kernel appears to be installed correct 4.2.0-3-upboard.

Am I missing a step to get this UART device to appear correctly?

Thank you

The documentation doesn't seem to be correct. The UART1 pins are actually ttyS4 and not ttyS1 as indicated on the website. I came across this myself and was able to get serial working by doing to the following (as root).

>> stty -F /dev/ttyS4 9600
>> cat /dev/ttyS4

Hope this helps.

Thanks for your comment.

I also discovered this. ttyS4 is working great for me.
