I'm trying to get my 3DRradio on APM2 using UART2 along the resetButton edge.

I already have UART0 working on the reset button side as my muxUART0/2 worked for a day and must have broken like the others, but I would like to avoid unplugging the radio every time I need to connect with USB - I'm afraid I'll fatigue those traces eventually too.

If the radio were on UART2 I could connect with either USB or radio (obviously not both) without pulling one or the other. Is this possible & how would I do this?

I'm not sure what parameters need to be changed, merely connecting to UART2 doesn't work.  Not sure if JP1 needs to be reconfigured for UART2, but I would think that's just for the sensor-side pins not for the pins along the reset button edge.

Wouldn't this be a better default setup for those who can't even use the mux pins?

If this procedure is not possible, I'll just throw a small toggle switch on the radio GND...

Thanks in advance for any help!
