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'sEmbedded Linux Primerhas 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.

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.
