嵌入式Linux在s3c2440上的移植

摘要

ARM processor has already become the lead in the market of embedded system.Porting operating system is the precondition and the foundation for the development of an embedded system.However,porting embedded operating system can be very complicated.Aiming to port embedded Linux on s3c2440,discusses the method and the steps of porting embedded Linux by porting embedded Linux kernel inside the target board of S3C2440 processor.The compiled Linux kernel circulating in the embedded system show s stability and the root file system can be normally loaded into kernel by Ramdisk.The result proved that the method is workable and has implications for other embedded operating system.%在嵌入式系统里基于ARM的嵌入式处理器已经成为市场主流,移植操作系统是开发嵌入式系统的前提和基础,而嵌入式操作系统的移植比较复杂。针对嵌入式Linux在s3c2440上的移植目的,通过将嵌入式Linux内核移植到S3C2440处理器的目标板上,提出了嵌入式Linux移植的方法与具体实现过程。编译生成的内核在嵌入式系统中运行稳定,制作的根文件系统可以通过Ramdisk方式正常加载进内核。结果证明方法可行,同时对于开发其他类型的嵌入式系统具有一定的参考意义。
