how to add nrfjprog to west flash a real hardware board?

[jiaqiwang969]

I am connect my nrf9160 sd board into the nixos, with zephyr-rtos.nix env.

when i type west flash, it log: fatal error: required program nrfjprog not found; install it or add its location to path

Seems currently NixOS lacks packaging for nrfjprog. Could you seek for alternative flashing options for you hardware (OpenOCD)? Or you can add it youself.

Thanks. I found the way:

First, add J-Link v7.94e

Second, install nrf command line tools

Finally, add path in flake.nix:

devShells = forAllSystems (system: { default = nixpkgsFor.${system}.mkZephyrSdk { shellHook = '' export PATH=$PATH:/opt/nrf-command-line-tools/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/nrf-command-line-tools/lib ''; }; });
