Hi all,
I need to interface with a TTL UART-based peripheral and am looking for a more robust/permanent solution than soldering on to TP123/125. Is it possible to route the unused UART (UART2, mxctty1 if I recall correctly) to one of the expansion headers? Has anyone been successful with this?
If not, what is the best way to expose a basic UART (Tx, Rx, Vcc, GND only -- no need for CTS/RTS) to a peripheral?
For record, I am running a Yocto-based 3.10.17-1.0.1 kernel on a Quad.
Thanks for your help!
