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().

Automation Tools

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