Learn how image features determine what goes into a Yocto image by examining the core image class and the image_features variable, including debug tweaks, splash, and package groups.
Learn how Bitbake parses a recipe, derives fetch, unpack, patch, configure, compile, install, and package tasks, and how to control the build with -c and task lists in Yocto.
Learn how to declare licenses in yocto recipes, specify the license and license file checksum, and handle gpl v2 when licensing appears in source or a separate file.
Understand how do_compile and do_configure use run make to execute make when a makefile exists, otherwise run make clean, with error checks such as die make failed.
