Diving into BitBake Metadata

At this point in this book, we know how to generate images and packages and how to use package feeds – basically, everything we must know for the simple usage of Poky. Hereafter, we will learn how to control the behavior of Poky to accomplish our goals and achieve maximum benefit from the Yocto Project as a whole.

This chapter will help enhance our understanding of the BitBake metadata syntax. We will learn to use the BitBake operators to alter the content of variables, variable expansions, and so on. These are the key concepts we can use to make our recipes and the customization that we will learn about in the following chapters.
