Open Build Setup to inspect the detected project and its source configuration.
  • CMake: choose a configure/build preset when the project defines one. Without presets, choose a build configuration such as Debug or Release. The project’s toolchain file owns compiler selection.
  • PlatformIO: choose one discovered environment. Build and Upload are scoped to that environment.
  • Zephyr: enter the exact board target from your installed SDK and apply it. west boards in the SDK environment lists targets. Prescaler invokes west with that board; west may regenerate its build directory when required.
  • ESP-IDF: build through the project’s SDK environment with idf.py.
Read the configure result separately from the compilation result. Failed configuration cannot be repaired by flashing a previous image. Build Output retains the actual command and diagnostics; Problems provides source navigation. Use Clean only when needed. A clean can remove generated outputs and make the next build slower. It does not change your source configuration.

Reproducibility checklist

Record the source revision, SDK/compiler version, native configuration and image identity. Store native configuration files in version control. Avoid absolute machine-specific SDK paths in shared project files where the native format supports portable paths. See CMake, PlatformIO, Zephyr, or ESP-IDF.
