Zephyr Build System

Efficiently manage the complex build and configuration stack of Zephyr RTOS.

Core Workflows

1. West Workspace & Manifests

Manage multi-repo projects and dependency allow-lists.

  • Reference: west.md
  • Key Tools: west init, west update, west manifest --resolve, name-allowlist.

2. Kconfig Configuration

Tune software features and hardware parameters.

  • Reference: kconfig.md
  • Key Tools: west build -t menuconfig, symbol searching (/), help (?).

3. Sysbuild & Multi-Image

Configure complex projects like MCUboot + Application.

  • Reference: cmake.md
  • Key Tools: west build --sysbuild, sysbuild.conf.

4. CMake & Project Structure

Core build logic for applications and modules.

  • Reference: cmake.md
  • Key Tools: CMakeLists.txt, zephyr_library(), target_sources().

Quick Start (Workspace + Build)

west init -m <manifest-repo-url> zephyr-workspace
cd zephyr-workspace
west update
west build -b native_sim samples/hello_world

Validation Checklist

  • west update resolves all manifest projects without errors.
  • west build succeeds for at least one known target board.
  • Required Kconfig symbols are present in build/zephyr/.config.
  • scripts/find_modules.sh reports module names that match the current manifest allow-list.

Automation Tools

  • find_modules.sh: Scan your build/ directory to automatically identify which modules you should add to your manifest's name-allowlist.
