Yocto’s Mental Model and a Resource-Conscious Host

Explain how metadata, configuration, tasks, and shared state produce deterministic build artifacts.

Select a maintained Yocto LTS branch and use its matching documentation and release notes.

Validate an Ubuntu 22.04 host against the selected release’s package, locale, filesystem, and shell requirements.

Estimate build storage consumption and configure a cleanup strategy suitable for a 100 GB workspace.

Clone the selected Poky branch and initialize an isolated build environment with oe-init-build-env.

Explain the purposes of source, build, downloads, shared-state, temporary, and deployment directories.

Set BB_NUMBER_THREADS and PARALLEL_MAKE conservatively from the host’s CPU and 16 GB RAM constraints.
