Hi All,
I have a couple of nRF9160-DK which I use to program custom boards through the Debug Out port. Both DK work perfectly well until now. One of them can't program custom board anymore. Firmware always goes to the on-board nRF9160 instead of going out to the custom board. I have checked all DK settings between the two DK and they are identical. The 10-pin cable is fine. What could be the problem here? Any chance the firmware in the Interface MCU needs to be reflashed?
