| 摘 要： | U-boot是一款应用比较广泛的嵌入式Bootloader，能够支持TFTP协议从网口下载内核映像，但不支持从NAND Flash启动，也没有对S3C2440的支持，本文主要工作就是实现U-boot从NANDFlash启动，移植到UTT2440S上。文中首先简要介绍了U-boot的启动流程，详细地介绍U-boot基于NANDFlash启动的移植步骤，对移植工作进行了分析，并对移植的U-boot进行了测试，可以稳定的工作。

| Abstract: | U-boot is used widely in embedded system, it can download kernel image through net chip with TFTP protocol, but can＇t boot from NAND Flash and don＇t support S3C2440. The main work of this paper is to implement booting from NAND Flash,porting to UTT2440S. This paper briefly introduced booting process of U-boot, detailedly introduced U-boot porting steps booting from NAND Flash. Analyse the porting and test the ported U-boot,it can work steadily. |
