J20, pins 2 & 3, on Kore carrier are TX/RX serial pins but I’ve been unsuccessful in getting them to work. I’m loading PX4
master branch. My colleague successfully uses the
nsh console in this same config. The scope trace looks like the pins are in high-impedance mode.
Is there a switch, or some form of board config setting that must be set to use the TX/RX pins on J20?
