【摘要】：嵌入式系统开发、生产过程中涉及到的一个很重要的问题就是“镜像文件烧写”,镜像文件的烧写方案直接关系到嵌入式设备的开发、生产效率。目前国内很多嵌入式设备厂商的生产模式都是沿用嵌入式开发板提供的烧写方案,生产效率比较低下。本文针对嵌入式产品生产线上对镜像文件烧写的特殊需求,根据嵌入式处理器IROM启动的特性,探讨了基于IROM启动的嵌入式系统镜像文件便捷烧写方法的设计,并具体实现了对镜像文件的“一键烧写”——只需选择“一键烧写”菜单项或执行“一键烧写”命令即可自动完成所有镜像文件的烧写,实现了对镜像文件的自动烧写——嵌入式系统上电后便自动读取镜像文件并自动完成所有镜像文件的烧写任务。本文的主要研究内容和成果如下： 1.阐述了嵌入式系统发展现状以及完成烧写功能的Bootloader的相关基础理论；研究了嵌入式处理器的启动方式,并对嵌入式处理器的IROM启动方式做了详细的分析； 2.研究了嵌入式系统镜像文件及其烧写,分析了当前嵌入式系统镜像文件的烧写机制,并提出了嵌入式镜像文件烧写的“自主烧写”和“代理烧写”的概念,详细对比了当前“自主烧写”中存在的各种烧写方法； 3.设计了基于IROM启动的嵌入式系统镜像文件快捷烧写方法,并基于S3C6410处理器和U-Boot,利用SD卡启动机制,实现了IROM启动下的嵌入式系统镜像文件的“一键烧写”和“自动烧写”。实验证明,本文实现的“一键烧写”和“自动烧写”方法,操作方便、省事、速度快、成本低,只要“一键”或者自动就能完成全部镜像文件的烧写。特别适用于嵌入式设备的大规模量产阶段。
[Abstract]:In the development of embedded system, a very important problem involved in the process of production is "image file burning". The burning and writing scheme of image file is directly related to the development and production efficiency of embedded equipment. At present, the production mode of many embedded equipment manufacturers is based on the burning scheme provided by embedded development board, and the production efficiency is relatively low. Aiming at the special requirement of image file burning in embedded product line, according to the characteristic of embedded processor IROM, this paper discusses the design of embedded system image file burning method based on IROM boot. And realized the mirror image file "one key burn write"-just select "one key burn write" menu item or execute "one key burn write" command can automatically complete all the image file burn, The image file can be automatically burned-the embedded system can automatically read the image file and finish all the image writing tasks automatically after the embedded system is powered on. The main contents and achievements of this paper are as follows: 1. This paper expounds the development of embedded system and the basic theory of bootloader, studies the startup mode of embedded processor, and makes a detailed analysis of the IROM boot mode of embedded processor. 2. This paper studies the embedded system mirror file and its writing, analyzes the burning mechanism of the embedded system image file, and puts forward the concepts of "autonomous writing" and "proxy writing" of the embedded image file burning and writing. In this paper, various writing methods are compared in detail. 3. This paper designs a fast writing method of embedded system image files based on IROM, and based on S3C6410 processor and U-Boot. using SD card startup mechanism, the embedded system image files under IROM boot are realized by "one key burn" and "automatic writing". It is proved by experiments that the methods of "one key writing" and "automatic writing" are easy to operate, fast and low cost. As long as "one key" or automatic writing can complete the burning and writing of all the mirroring files. It is especially suitable for mass production stage of embedded equipment.
