# Zephyr and Nordic SDK projects

> Build using the SDK board target, configuration fragments and generated headers.

Open the application root. Activate the intended west/SDK environment and use `west boards` to obtain the exact board target, including revision and qualifiers.

In Build Setup, enter and apply **SDK board target**. Build uses west with that board and the build directory. A board change can require regeneration; inspect the native output before reusing any artifact.

Keep application options in `prj.conf`, overlays and the native board configuration. These files belong to the build and should be version-controlled. Prescaler currently links native sources; it does not advertise a complete replacement for Nordic's Devicetree/Kconfig editors.

For multi-image/sysbuild projects, explicitly verify which domain produced the image and which runner programs it. Do not treat a unique file found elsewhere in the repository as the active image.
