Summary

In this chapter, you were presented with information on bootloaders, with particular focus on the U-Boot bootloader. We also discussed topics related to U-Boot interaction, porting, debugging, general information on bootloaders, U-Boot alternatives and a boot sequence inside an embedded environment. There was also a section related to the Yocto Project, where you were introduced to the mechanism used to support various bootloaders available inside BSP. A number of exercises were presented across the chapter, and they offered more clarity on this subject.

In the next chapter, we will discuss the Linux kernel, its features and source code, modules and drivers, and, in general, most of the information needed to interact with the Linux kernel. As you have already been introduced to it, we will also concentrate on the Yocto Project and how it is able to work with various kernel versions for a number of boards and exercises. This should ease the understanding of the information presented to you.
