Understanding Poky

Poky is the default Yocto Project reference distribution, which uses OpenEmbedded build system technology. It is composed of a collection of tools, configuration files, and recipe data (known as metadata). It is platform-independent and performs cross-compiling using the BitBake tool, OpenEmbedded Core, and a default set of metadata, as shown in the following figure.
