Install on Windows

The Windows commands live on the main Install page, in the Windows tab of each step. Run NSX from PowerShell or Windows Terminal.

In short:

winget install Python.Python.3.12 astral-sh.uv Kitware.CMake Ninja-build.Ninja Git.Git
# Arm GNU toolchain: run the official installer, tick "Add path to environment variable"
# SEGGER J-Link: run the J-Link Software and Documentation Pack installer
uv tool install neuralspotx
nsx doctor

Windows steps are unverified

Every command in this section was executed on macOS. The Windows steps are carried over from the previous documentation and have not been re-run on a Windows host, so treat the winget package identifiers and the installer wording as unverified for now.

Optional toolchains

GCC builds every packaged example. Both alternates below are optional, and nsx doctor reports them only when it finds them.

Arm Compiler for Embedded (armclang)

A licensed commercial compiler. Install it from Arm, make sure armclang is on your PATH, and NSX picks it up. No environment variable is needed. Select it per command with --toolchain armclang.

Arm Toolchain for Embedded (ATfE)

ATfE is Arm’s LLVM based bare-metal toolchain (clang, lld and picolibc with a newlib overlay). NSX treats it as experimental.

1. Download the Windows build from the Arm Toolchain for Embedded releases.

2. Extract it somewhere stable, for example C:\ATfE-22.1.0.

3. Extract the matching ATfE-newlib-overlay on top of that same directory. NSX and nsx doctor both need the bundled newlib.cfg.

4. Point ATFE_ROOT at the install directory. ATfE does not need to be on PATH, because NSX invokes its binaries by absolute path.

   setx ATFE_ROOT "C:\ATfE-22.1.0"

Select it per command with --toolchain atfe.

Check your environment with nsx doctor.
