摘　　要：嵌入式平台多种多样,在一个特定的嵌入式系统应用Linux内核,需要内核的移植和驱动的开发。基于S3C2440芯片的嵌入式开发平台,操作系统选用Linux2.6.22.6版本,分析了Linux内核的体系结构,完成了内核移植过程,构建了根文件系统,对字符设备驱动程序进行了设计与开发。实验证明该方法可行,系统运行可靠。It is important to port kernel system and code driver when applying Linux kernel in a special embedded platform.In this work,the embedded platform has been adopted Linux 2.6.22.6 system based on S3C2440 processor.The architecture of Linux kernel is described in detail,and kernel system has been ported successfully in this paper.Meanwhile,the root filesystem has been established.Furthermore,a character device driver is built as well.

关 键 词：S3C2440 内核移植 根文件系统 字符设备驱动
