摘　　要：Bootloader是系统上电或复位后首先运行的一段代码,是连接操作系统和硬件的桥梁,负责初始化硬件和引导操作系统等。目前已有很多通用的Bootloader,但是如何根据特定的嵌入式平台,移植自己的引导程序是一个重点和难点。文章详细说明了从Norflash引导操作系统要完成的主要任务和实现方法,并给出了试验结果。Bootloader is the first programs to run when the system turns on or reboots. And Bootloader is key joint between the operating system and the hardware, and also responsible for the initialization hardware and the guidance operating system and so on. Currently, there are some common Bootloaders, but how to develop and port it on the basis of special hardware platform is a important and difficult question. This paper analyses the important task and realization method of Bootloader by copy the programs from Nor/lash to store the SDRAM and run the OS.
