Abstract

ARM processor has already become the lead in the market of embedded system. Porting operating system is the precondi-tion and the foundation for the development of an embedded system. In this paper, the process of replanting ARM Linux based on AT91RM9200 platform includes downloading the kernel sound code, building the cross compile environment, replanting the U-boot, configuring and compiling kernel ,building the file system is introduced. The kernel which is ported on the board runs very well through several tests. The embedded Linux porting is helpful to exploit other embedded operating system.
