Delineating the Yocto Project
To ease our understanding of the duties and outcomes of the Yocto Project, we can use the analogy of a computing machine. The input is a set of data that describes what we want, that is, our specification. As an output, we have the desired Linux-based embedded product.
The output is composed of the pieces of the operating system. It encompasses the Linux kernel, bootloader, and the root filesystem (rootfs
) bundled and organized to work together.
The Yocto Project’s tools are present in all intermediary steps to produce the resultant rootfs
bundle and other deliverables. The previously built software components are reused across builds – applications, libraries, or any software component.
When reuse is not possible, the software components are built in the correct order and with the desired configuration, including fetching the required source code from their respective repositories, such as The Linux Kernel Archives (www.kernel.org...
