pc-nrfjprog-js

Node.js library that exposes the functionality of the nRF Command Line Tools, used for development, programming, and debugging of Nordic Semiconductor's SoCs (System on Chip).

Installing

The library can be installed from npm, using:

npm install pc-nrfjprog-js

This will pull down precompiled binaries for your platform/runtime environment. If precompiled binaries do not exist, then npm will try to compile them, which requires:

• Node.js (>=4)
• npm (>=3.7.0)
• CMake (>=2.8.12)
• A C/C++ toolchain

As part of the installation procedure, pc-nrfjprog-js will check if it can access the nrfjprog libraries, and verify that they are up to date. If not, it will try to install/upgrade these libraries.

Building from source

The library can be built from source, using:

npm run build

The library can be build from source while installing, using:

npm install --build-from-source

Building from source requires the tools from Installing to be installed.

Required setup

SEGGER J-Link Software must be downloaded and installed.

If you are seeing errors like Errorcode: CouldNotLoadDLL (0x3) then please check that the J-Link library is properly installed.
