摘要
操作系统引导程序—BootLoader是嵌入式系统软件开发的第一个环节,在整个开发过程中占有极重要的地位。本文详细论述了BootLoader的运行机理,并以在三星公司的S3C44B0X处理器上uClinux的引导程序的开发为实例,着重分析了FLASH,RAM的存储空间分配,介绍了GNU工具链的开发流程、可执行映象文件在存储空间的定位及uClinux内核的相关配置。
Os bootstrap program （BootLoader） is the first step in developing software of embedded system. It is very important in the whole developing process.This article discussed the mechanism of BootLoader in detail .Taking the development of uClinux bootstrap program to S3C44BOX processor of Samsung corp as example, it analyzed the memory allocation of FLASH and RAM expressly, introduced the development process of GNU and the location of execute image files and related configuration to the kernel of uClinux.
