nRF Command Line Tools Desktop tool

Cross-platform desktop software

The nRF Command Line Tools is used for development, programming and debugging of Nordic Semiconductor's nRF51, nRF52, nRF53 and nRF91 Series devices.


Components:

  • SEGGER J-Link software and documentation pack
  • mergehex executable - enables you to combine up to three .HEX files into one single file
  • nrfjprog DLL - a DLL that exports functions for programming and controlling nRF51, nRF52, nRF53 and nRF91 Series devices and lets developers create their own development tools using the DLLs API
  • nrfjprog executable - tool for programming through SEGGER J-LINK programmers and debuggers - nrfjprog is officially deprecated and is being replaced by nRF Util. This affects the nRF Connect SDK v2.8.0, where nrfjprog will be removed in an upcoming release. Use nRF Util for all related tasks going forward.
