摘要:
在PC机上电后会执行BIOS程序,BIOS程序负责初始化DDR内存和硬盘,从硬盘上将操作系统镜像读取到DDR中,然后跳转到DDR中去执行操作系统直到PC机启动.在嵌入式系统中的部署和启动都是参考PC机的,U-boot程序类似于BIOS程序,部署在Flash上,是内核运行前一段小程序,完成对必要硬件的初始化,传递内核启动信息,提供命令行供人操作,最终调用操作系统,起到引导和加载内核的功能.文中详细介绍了基于CortexA8微处理器的s5pv210的移植与研究,包括U-boot的启动、移植、配置等过程,最终通过tftp加载内核和nfs远程挂载根文件系统,在开发板上实现Linux系统的启动.
Abstract:
The BIOS program is responsible for initializing DDR memory and hard disk．reading the operating system image from the hard disk into DDR，and then jumping to DDR to execute the operating system until the PC StaRS．The deployment and stanup in the embedded system are based on Pc．The U-boot program is similar to the BIOS pmgram and deployed on Rash．It is a small program before the kcmel runs，completes the initialization of necessary hardware，passes the kernel startup information，provides the command line for human operation，and finally calls the operating system，playing boot and loading kernel functions．In this paper，we introduce the trailsplantation and research of s5pv210 based on CortexA8 microprocessor．Including the process of U-boot starmp，porting and configuration．Finally，we implement the startup of Liunx system on the development board by tftp loading kernel and nfs[emote loading root file system．
