摘要
嵌入式系统设计中引入操作系统以实现复杂的控制功能,启动加载程序主要完成操作系统引导启动任务。目前嵌入式系统中主流的启动加载程序都只支持Nor Flash启动,不支持Nand Flash启动。针对Nand Flash和Nor Flash的各自特点,给出了使启动加载程序在启动时自己识别自身所处于何种Flash而采取相应的动作的启动方案。弥补了目前的启动加载程序只支持单一Flash启动的不足,增加了启动加载程序的通用性。
In order to control complexity functions through embedded system,operating system is introduced to meet this target,the bootloader is needed to boot the OS. But the popular embedded systems＇s bootloader to start only support of Nor Flash, do not support the Nand Flash. counter the Nand Flash and Nor Flash characteristics respectively,the bootloader during the boot time to identify themselves by their own what kind of Flash to take appropriate action program is given,the current bootloader only supports the single kind Flash is made up,and universality of bootloader is inereased.
