From the Back Cover
Up-to-the-Minute, Complete Guidance for Developing Embedded Solutions with Linux Linux has outstripped all competitors as today's #1 operating system for embedded products. Christopher Hallinan's "Embedded Linux Primer" has proven itself as the definitive real-world guide to building efficient, high-value, embedded systems with Linux. Now, Hallinan has thoroughly updated this highly praised book for the newest Linux kernels, capabilities, tools, and hardware support, including advanced multicore processors. Drawing on years of experience as a consultant and field application engineer, Hallinan helps you rapidly climb the learning curve, whether you're moving from legacy environments or you're new to embedded programming. Hallinan addresses today's most important development challenges, and demonstrates how to solve the problems you're most likely to encounter. You'll learn how to build a modern, efficient embedded Linux development environment, and then utilize it as productively as possible. Hallinan offers up-to-date guidance on everything from kernel configuration and initialization to bootloaders, device drivers to file systems, and BusyBox utilities to real-time configuration and system analysis. This edition adds entirely new chapters on UDEV, USB, and open source build systems. Throughout, Hallinan presents extensive downloadable code examples-all assembled from operational hardware running the latest versions of embedded Linux. - Tour the typical embedded system and development environment, and understand its concepts and components. - Compare the standalone and integrated processors that Linux now supports. - Understand the Linux kernel and userspace initialization processes. - Walk through bootloading, with specific emphasis on Das U-Boot, the most popular Linux bootloader for embedded systems. - Understand Linux device driver concepts, architecture, and licensing, and the role device drivers play in virtual memory operating systems. - Choose the right Linux file system for your application. - Use the Memory Technology Devices (MTD) subsystem to interface with flash (and other) memory devices. - Make the most of BusyBox, the Linux embedded development environment, and the latest open source development tools. - Expanded and updated coverage of kernel debugging. - Build and analyze real-time systems with Linux. - Learn to configure device files and driver loading with UDEV. - Detailed coverage of the USB subsystem - Introduction to the latest open source embedded Linux build systems in use today - "Reference appendices include U-Boot and BusyBox commands, SDRAM interface considerations, sample BDI-2000 configuration file, and more."
About the Author
Christopher Hallinan is a technical marketing engineer for the Embedded Systems Division of Mentor Graphics, living and working in Florida. He has spent more than 25 years in the networking and communications industry, mostly in various product development, management, and marketing roles, where he developed a strong background in the space where hardware meets software. Prior to joining Mentor Graphics, he spent nearly seven years as a field applications engineer for Monta Vista Software. Before that, Hallinan spent four years as an independent Linux consultant, providing custom Linux board ports, device drivers, and bootloaders. His introduction to the open source community was through contributions to the popular U-Boot bootloader. When not messing about with Linux, he is often found singing and playing a Taylor or Martin.

To begin with I have had minimal experience with embedded linux systems, but I have had experience in legacy C and C++, as well as Linux system administration.
The author is a very efficient writer and explains concepts in a very easy to understand, concise way. If you have had experience with C programming and basic Linux system administration you will understand the examples he presents and walks through. The author provides excellent examples in the form of diagrams and Linux command line screenshots that help to reinforce what is being explained. Furthermore, the author provides EXCELLENT resources at the end of each chapter to steer the reader towards more "in-depth" texts. These resources are incredibly useful as they serve to help keep the book up-to-date.
In Response to Other Reviews
- The author does provide links to community based embedded Linux systems in Chapter 2. and recommends the system he is running, for the examples seen throughout the book.
- I agree that it would be nice to see more links and references to more community projects but it should in no way affect the potential buyer (the author provides plenty of examples, but take into account that the book is a static entry, he can't continuously update it to keep current with technology).
For the Potential Buyer
- This is a primer, do not expect a "cookbook" format, as that is not the intent of the author. The primer approach is meant to educate you on the big picture and prepare you to go into more depth. If you purchase this book with this in mind you will absolutely not be disappointed.
- The author speaks clearly and simply to educate on the issues that are pertinent to embedded systems.
Expectations of the Reader:
The author expects the reader to be able to understand two things in order to follow along in the book:
(1) The ability to read C code and,
(2) Familiarity with Linux system administration
The book provides a very good presentation style in chapter organisation and sub structure. Abstract, logical coherent walkthough a theme, summary, reference for further reading. The coverage of the general topics of embedded linux development is given so any entering developer gets a good overview whats ahead of him. Language is balanced relaxed and entertaining without being distracting. Even as a non native english person I enjoyed the reading.
some reviewers complained about missing details and how tos. This book is not a how to build a particular system solution nor provides it details down to a working solution on any aspect under regard. Why should it? Details down to source code is provided in any thinkable form in the internet. All this distributed knowledge lacks of coherence and evaluation. This is where the Primer comes in. It provides what cannot be found easily in a consumable form. Overview, Impression of complexity and probable solution pathways.
reference for those who seek knowledge rather than solutions.
My only suggestion (which shouldn't affect the 5-star review given to the book): please cover more details community-based embedded linux systems such as BeagleBoard/BeagleBone and Raspberry-Pi. Curious readers, especially hobbyists and students, could then practice what said in the book directly using these affordable embedded devices. I think this make this a 6-star book to learn embedded linux.
my background: I develop in C++ and objective-c, but I have very little experience with Linux in general, and basically no experience with any embedded system.
The book is easy to follow; has good info about how the system works, and overall is a good guide to start moving the first steps into the embedded world. It is the first of it's kind that I read, so I do not know what others would expect; to me it does what it says: it is a primer for embedded systems using linux, and it is more than what I was hoping for so far.
