Highlights
Yocto Project is an open-source initiative that provides tools and frameworks for creating custom Linux distributions (specifically embedded Linux distributions). ⤴️
Yocto Project is not an operating system itself but a set of tools that allow developers to precisely configure, compile, and deploy their versions of Linux, tailored to the specific requirements of their projects. ⤴️
Poky which is the reference distribution of the Yocto Project. It includes the OpenEmbedded build system, which is the core engine for building distributions, as well as a set of metadata that defines the core packages and recipes for the base system. Poky serves as a starting point for developing your own custom Linux distribution. ⤴️
OpenEmbedded Core (OE-Core) is a subset of the OpenEmbedded project, which provides a layer of metadata used by the Yocto Project. OE-Core contains the base set of recipes, classes, and associated files for building basic Linux features and serves as the foundation upon which additional layers and customizations can be built. ⤴️
BitBake is a task executor and scheduler used to perform the builds. It reads the metadata (recipes and configurations) and executes the tasks required to build the specified target. BitBake handles dependency resolution, task scheduling, and execution, making it a central component of the Yocto Project build system. ⤴️
Board Support Packages (BSPs) in the Yocto Project are crucial components that allow Linux systems to be customized for specific hardware platforms. They include drivers, kernel configurations, bootloaders, and other elements necessary for the OS to operate on a given device. BSPs enable developers to adapt the Linux system to diverse hardware requirements efficiently, facilitating the development of embedded projects tailored to specific needs. ⤴️
After building, you can test the image on your target hardware or using an emulator to ensure everything works as expected. ⤴️
