虽然很多公司将LINUX用于多种嵌入式系统，从手机到汽车ABS系统和水过滤设备，但是令人惊讶的是，关于LINUX系统内核和相关工具的建立、安装、测试这方面信息的资源几乎没有。
《构建嵌入式LINUX系统》是一本构造这些系统的详细指南，不仅可以学习基本原理，而且可以学习如何去配置、设置并使用40种以上不同的开发源码和自由软件包。
此次再版，更新了上一个版本的LINUX系统内核和之前无证程序的特征，以助你：
·建立自己的GNU开发工具链
·选择、配置、构建并安装特定目标的内核
·建立完整的目标根文件系统
·设置、操作及使用固态存储设备
·安装并配置目标的引导加载程序
·交叉编译大量实用程序和包
·使用多种工具和技术调试嵌入式系统
·使用uClibc， BusyBox, U-Boot, OpenSSH, thttpd, tftp, strace和gdb包
·利用Xenomai或RT内核补丁的实时特征
此次再版教授了如何构建操作系统组件，简化了嵌入式系统中令人望而生畏的完全控制的维护任务。
