基于S3C2440的嵌入式Linux内核移植及字符设备驱动开发

摘要

It is important to port kernel system and code driver when applying Linux kernel in a special embedded plat-form.In this work,the embedded platform has been adopted Linux 2.6.22.6 system based on S3C2440 processor.The archi-tecture 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 wel.%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.
