Hi Everyone, I would like to connect two external devices via UART to the A9 board. From the documentation, and previous thread (see references below) only UART6 (/dev/ttymxc5) works. Could someone please confirm if this is the case? if not, then how can you enable another UART port? Thanks!

If your not using UART5 (or the pins) on the M4 side then you can reallocate it to the A9 side, however I'm not sure if this is possible through the device tree editor. If not then you need to 'hack' the dts files, recompile and deploy. Alternatively you can plugin a usb to serial adapter (eg like a CP1202) to gain another serial port.
