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.
