In this chapter, you learned how to prepare our host system to use it as a Yocto Project development host. You also learned how to build BeagleBone images using Yocto Project, prepare an SD card, boot the board from this card, and set up serial communication to the board to take a sneak peek into it. We discussed most of the configuration files in this chapter. We took a brief look at some extra configuration files, as well. In the next chapter, you will learn about the core tool behind Yocto Project, which is BitBake, in detail. You will also learn about its various options and how we can use them to make our lives easier.
