Understanding Poky

Poky is the Yocto Project reference system and is composed of a collection of tools and 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. It provides the mechanism to build and combine thousands of distributed open source projects to form a fully customizable, complete, and coherent Linux software stack.

Poky's main objective is to provide all the features an embedded developer needs.
