RE: Software Development for NRF9160 Production Programming

Hi Shubham,

You have a few options:

First of all, there is our "nrfjprog DLL", a dynamic-link library which exposes functions for device programming. This DLL is used as the backend of nrfjprog.exe, but the architecture is split like that so that users like you may use the DLL directly:

Besides that, I think it's quite common for customers to just spawn an entire subprocess instead, calling either nrfjprog.exe, or nrfutil.exe.

(We are currently in a transition towards nrfutil being a single command line utility for everything, so in time, nrfjprog will be phased out.)

Spawning a subprocess might have a slight performance penalty but is easier to implement. Do you have a need for speed?

Customers who flash lots of devices and need very high throughput, they usually write their own flashing software from scratch.

In that case, this page will be useful: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnan_041%2FAPP%2Fnan_production_programming%2Fintro.html&cp=2_0_7

Those are the options I know of. Unfortunately we don't have any libraries in source form, if you were looking for that.

Best regards,

Raoul
