Go deeper before writing your own recipes.

  • Variable scoping and overrides (:append, :prepend, :remove)
  • Task dependencies (do_compile[depends])
  • devshell for debugging inside the build environment
  • bitbake -e <recipe> to inspect expanded variables
  • Understand WORKDIR, S, D, STAGING_DIR
  • Write a trivial recipe from scratch (hello world binary)
