内容提要

  

    克里斯·西蒙兹著的《精通嵌入式Linux编程(影印版)(英文版)》带领你检视整个产品周期，深入讲解每个产品阶段用到的组件和选项。首先学习的是工具链、bootloader、Linux内核以及根文件系统的配置方法。然后学习使用两种最常用的构建系统（Buildroot和Yocto Project）来加快和简化开发过程。打下了坚实的基础之后，接下来要讲述如何发挥出raw NAND/NOR flash memory（闪存）和managed flash（管理闪存）eMMC芯片的效用，其中包括延长设备生寸期以及执行可靠性in-field更新的机制。随后要讲到POSIX线程的用法，这对于最终设备的响应性以及性能有着极大的影响。最后会介绍一些性能分析技术以及使用perf和ftrace跟踪应用程序和内核代码。本书适合于熟悉嵌入式系统，希望学习如何制造一流设备的Linux开发人员以及系统程序员。要求读者具备基本的C语言基础和系统编程经验。
