Print ISBN-13: 978-0-13-167984-9. Pages: 576. Table of Contents | Index Comprehensive Real-World Guidance for Every Embedded Developer and Engineer This book brings together indispensable knowledge for building efficient, high-value, Linux -based Embedded products: information that has never been assembled in one place before. Drawing on years of experience as an Embedded Linux consultant and field application engineer, Christopher Hallinan offers solutions for the specific technical issues you're most likely to face, demonstrates how to build an effective Embedded Linux environment, and shows how to use it as productively as possible.

2 Hallinan begins by touring a typical Linux -based Embedded system, introducing key concepts and components, and calling attention to differences between Linux and traditional Embedded environments. Writing from the Embedded developer's viewpoint, he thoroughly addresses issues ranging from kernel building and initialization to bootloaders, device drivers to file systems. Hallinan thoroughly covers the increasingly popular BusyBox utilities; presents a step-by-step walkthrough of porting Linux to custom boards; and introduces real-time configuration via CONFIG_RT--one of today's most exciting developments in Embedded Linux .

3 You'll find especially detailed coverage of using development tools to analyze and debug Embedded systems--including the art of kernel debugging. Compare leading Embedded Linux processors Understand the details of the Linux kernel initialization process Learn about the special role of bootloaders in Embedded Linux systems, with specific emphasis on U-Boot Use Embedded Linux file systems, including JFFS2--with detailed guidelines for building Flash- resident file system images Understand the Memory Technology Devices subsystem for flash (and other) memory devices Master gdb, KGDB, and hardware JTAG debugging Learn many tips and techniques for debugging within the Linux kernel Maximize your productivity in cross-development environments Prepare your entire development environment, including TFTP, DHCP, and NFS target servers Configure, build, and initialize BusyBox to support your unique requirements About the Author Christopher Hallinan, field applications engineer at MontaVista software, has worked for more than 20 years in assignments ranging from engineering and engineering management to marketing and business development.

4 He spent four years as an independent development consultant in the Embedded Linux marketplace. His work has appeared in magazines, including Telecommunications Magazine, Fiber Optics Magazine, and Aviation Digest.
