摘要
通过修改U-boot-1.1.6版本的源码,设计并实现了从NAND Flash和NOR Flash两种启动的嵌入式Bootloader,并将其移植到S3C2440微处理嚣的嵌入式系统上。对bootloader的设计决定了实现的bootloader不仅仅起到加载内核镜像这一基本功能,而是把bootloader看作是一个虚拟的小系统,让其对硬件板级系统有更多的支持以为系统开发者提供方便。
By modifying the U-boot-1.1.6 version of the source code,the design and implementation of NAND Flash and NOR Flash from two to start the embedded Bootloader,and ported to the embedded system on S3C2440 microprocessor.in this paper,the design of bootloader to achieve the bootloader only played the basic function to load the kernel image,but the bootloader as a virtual system,make its have more support for system developers to provide convenient for hardware board level system.
