摘　　要：Boot Loader启动代码的分析与移植是嵌入式产品研发中最重要的环节之一。近年,嵌入式技术已取得了飞速的发展,但对于其最本质的核心部分Boot Loader的分析却不是很多。实践证明,Boot Loader的优越与否,对嵌入式系统的性能起到决定性的作用。文章根据Linux系统的编译环境及嵌入式系统的编程特点,分析了U-boot在ARM i.MX6Q嵌入式系统中的启动过程和移植过程。该研究对Boot Loader的设计有一定的借鉴作用。The analysis and transplantation of Boot Loader＇s bootcode is one of the most important parts in the development of embedded products.In recent years, the embedded technology has achieved a rapid development, but the analysis of the most essential core of the Boot Loader is not much.It has been proved that the advantages of the Boot Loader play a decisive role in the performance of the embedded system.Based on the compilation environment of Linux system and the programming characteristics of embedded system, this paper analyzes the start-up process and transplantation process of u-boot in the ARM i.MX6 Q embedded system.This paper has some reference to the design of Boot Loader.
