I used the Jlink to program the feather using the 6 pin Tag connect header and used nrfjprog in cmd line to program the board using the following command:
C:\Users\Chris>nrfjprog --program "C:\Users\Chris\OneDrive\Copper\copperCubeNRF9160\app\build\zephyr\merged.hex" --chiperase -f NRF91 --snr 50120338 --verify
I get the following results:
Parsing image file. Verifying programming. Verified OK.
I found this to not work and now when I try to program the board I get an error 3 in VSCode. Jlink can still attach to the CPU. Any thoughts on how to resolve this?
I can put the device into programming mode by holding the mode button and the blue led lights up consistently.
Any insight would be helpful, thanks!
