摘 要: | BootLoader移植是嵌入式系统开发中的一个重要环节,而Uboot是一个支持多处理器多操作系统较为通用的BootLoader。分析了Uboot的启动过程,并对s3c2440A如何支持驱动代码在外部NandFlash上的执行,以及在s3c2440A平台上如何实现NandFlash启动模式下的Uboot移植进行了介绍。具体操作和编译在fedora9操作系统和arm—linux-gcc4.3.2交叉编译下完成。

Porting of Uboot for Booting from NAND Flash Mode |
| |
Abstract: | Porting of BootLoader is a very important part in the embedded system development process. Uboot is a general bootloader, it supports multiple processors and multiple operating system. This paper analyzes booting process of uboot,and introduce s3c2440A how to support drive codes implement in the external NAND Flash , the end , gives ideas and implement methods about achieving booting uboot from NAND Flash based on S3C2440A platform. The specific operationand compile are finished in fedora 9 and arm-linux-gcc 4.. 3.2 cross compiler environment. |
