ARM系统中U-Boot的组织及开发

Organization and Developing of U-Boot in ARM System

U-Boot程序是一个独立的应用软件,其主要功能是对其所支持的处理器进行初始化并随后转到主应用程序.为优化对源代码的使用及提高效率,U-Boot由三部分组成:主引导程序、解压缩执行程序和被称为U-Boot影像的gzip格式的二进制可执行程序.

The U-Boot programs is a standalone software application that initializes the supported processor and then jumps to the main applicationing. To optimizprogram resource use and efficiency, U-Boot is made up of three parts: a primary bootstrap, a de-compression executable and a gzip-compressed binary executable which is called the U-Boot Image.
