Hi, I’m attempting to flash a Sparkfun Thing Plus nRF9160 for the first time (first time for it, and for me) but running into an NMP Timeout error.
$ newtmgr -c serial image upload build/zephyr/app_update.bin
0 B / 63.48 KiB 0.00%Error: NMP timeout
What does NMP stand for? I’d like to understand this message a little better.
I’m connecting to the board via USB-C to my Windows 10 PC, USB-A 3.0 slot.
Any recommendations to get past this hurdle, greatly appreciated.
