What this book covers
Chapter 1, Introduction, tries to offer a picture of how an embedded Linux software and
hardware architecture looks. It also presents you information on the benefits of Linux
and Yocto along with examples. It explains the architecture of the Yocto Project and
how it is integrated inside the Linux environment.
Chapter 2, Cross-compiling, offers you the definition of a toolchain, its components,
and the way in which it can be obtained. After this, information on the Poky repository
is given to you and a comparison is made with the components.
Chapter 3, Bootloaders, gives you information on a boot sequence, U-Boot bootloader,
and how it can be built for a specific board. After this, it gives access to the U-Boot
recipe from Poky and shows how it is used.
Chapter 4, Linux Kernel, explains the features of the Linux kernel and source code. It
gives you information on how to build a kernel source and modules and then moves on
to explain the recipes of the Yocto kernel and presents how the same things happen there
after that the kernel is booted.
Chapter 5, The Linux Root Filesystem, gives you information on the organization of root
file system directories and device drivers. It explains the various filesystems, BusyBox,
and what a minimal filesystem should contain. It will show you how BusyBox is
compiled inside and outside the Yocto Project and how a root filesystem is obtained
using Poky.
Chapter 6, Components of the Yocto Project, offers an overview of the available
components of the Yocto Project, most of which are outside Poky. It provides an
introduction and a brief presentation of each component. After this chapter, a bunch of
these components are explained in more detail.
Chapter 7, ADT Eclipse Plug-ins, shows how to set up the Yocto Project Eclipse IDE,
setting it up for cross development and debugging using Qemu, and customizing an
image and interacting with different tools.
Chapter 8, Hob, Toaster, and Autobuilder, goes through each one of these tools and
explain how each one of them can be used, mentioning their benefits as well.
Chapter 9, Wic and Other Tools, explains how to use another set of tools, very different
