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.
