Keywords:  Zephyr SDK installation :: Nordic nRF SDK installation :: JLinkARM installations

^ Overview

This wiki page intended to capture the various Nordic Semi toolchain elements which support the complete build, flash programming and Segger based debugging of Nordic nRF, Zephyr based applications. I quick list of tools to install:


  • all the Linux, Python, west, and sdk-nrf utilities and code base
  • gnuarmemb toolchain from GNU GCC for ARM downloads page
  • Segger JLink drivers from Segger's web site


A key finding on 2021-Sept-27 is that the gnuarmemb toolchain is for some reason necessary to call from Segger for compiling nRF Connect SDK projects. At the command line using `west`, both Zephyr's ARM compiler and the GNU ARM compiler (Zephyr's is GNU but just branded) succeed in building nRF Zephyr based apps. Attempts to call `/opt/zephyr-sdk-0.13.0/arm-zephyr-eabi/bin/arm-zephyr-eabi-gcc` cause a strange build error "offsets.c.obj does not exist".


^ Nordic Toolchain Install Closely Follows Zephyr Tools

Steps to installing Zephyr SDK and prerequisites in the context of NordicSemi's forked branch of Zephyr, and specifically details on `west init`, `west zephyr-export` and `west update`:

Instructions to install Zephyr SDK 0.13.0, note this is a Zephyr website page:

A recent version of GNU ARM gcc Ted finds will build nRF Zephyr based applications at the command line via `west`, but not when called from within Segger IDE Nordic version 5.60. A latest stable pre-compiled ARM gcc from GNU builds both at command line and in Segger:
