摘　　要：ARM微处理器与Linux的结合逐渐在嵌入式领域得到了广泛应用。文中描述了将Linux移植到基于ARM S3C2410微处理器的目标板上的方法与技巧,介绍了一套实用的针对表决器系统嵌入式平台的Linux移植方法,包括交叉编译环境的创建,Bootloader的编译,Linux内核的修改、配置和编译,Cramfs文件系统的制作等。移植后的Linux内核大小可以控制在700kB以下,既保留了很好的稳定性、安全性,又成功得到了"瘦身",减小了嵌入式平台上应用软件的开发难度,大大降低了嵌入式系统的开发成本。ARM microprocessor with a combination of Linux has been widely applied in the embeddedarea gradually. The article described the methods and skills on transplanting Linux to ARM $3C2410microprocessor-based target board. A set of pragmatic method of Linux transplantation has beenintroduced specifically for voting system, including building cross-compile environment, compilingBootloader, amending, configuring and compiling Linux kernel and producing cramfs file system and soon. After transplantation of Linux kernel, its size can be controlled in 700KB, which not only retainsvery nice stability, security, but also ＂loses weight＂ successfully. Consequently, the difficulty ofdevelopment in application software and the cost on embedded platform are both reduced.
