Embedded FreeBSD Cookbook (Embedded Technology)

A complete waste of time and money. This book is misrepresented in what it claims to be about. It contains very little information specific to embedded FreeBSD. The author should have written much more about minimizing the kernel, limiting memory usage, device driver development, and flash storage issues - because these are the topics that are the most relevent to an embedded system. The discussion about using Tomcat, JSP, and JNI to provide web access to an embedded device - while important - is severely lacking. A good book about an embedded operating system will explore the problems and trade-offs that a systems developer will have to make. It would also discuss getting the OS to run on a single board computer - such as one of the devboards listed in the FreeBSD ARM project. This book does neither.

However, detailed information on using FreeBSD is difficult to find. Author Paul Cevoli, an experienced embedded systems engineer, answers that need in this cookbook aimed at making life easier for engineers working with FreeBSD. Topics covered in the book include core operating system components, processes, process scheduling, virtual memory, device drivers and debugging, as these are the core features necessary for embedded system developers. The core software provided to the reader on the accompanying CD-ROM is written in C. Each chapter discusses basic components of FreeBSD, device drivers, Unix kernel, and C and GNU development tools, and provides the reader with the information needed to accomplish the stated task, along with sample source code.
