Summary

In this chapter, you were presented with the necessary information needed to understand the constituent components of a Linux toolchain, and the steps undertaken by developers to work or configure a Linux toolchain that is specific for a board or architecture. You were also presented information on the packages available inside the Yocto Project sources, and how the processes defined inside the Yocto Project are very similar to the ones already used outside of the Yocto Project context.

In the next chapter, we will breeze through information on bootloaders, with special emphasis given to U-Boot bootloader. You will also be given information on a boot sequence and a board's configurations inside the U-Boot sources.
