英文摘要：

The embedded technology develops at a tremendous speed in recent years, specially, the 32-bit embed- ded CPU with ARM core has been widely used in commerce, factory automation and military applications. Embedded Linux, the open source software, has much more advantages than other operating system. The porting and implementa- tion of the embedded Linux are introduced in this paper including bootloader, kernel, file systems and applications. And an example of realizing the embedded Linux System based on the AT91RM9200 developing board is given.
