The Reserch And Development Of The Embeded Linux Based On ARM9

With the development of computer technology,communication technology and the in-depth application of the Internet, more and more embedded systems are running around us. And because of the increasing complexity of the Embedded systems,the embedded operating system has become the most important part of the embedded system. In all kinds of embedded operating systems, Linux has the advantages of clear structure and open source,so it has been widely used in the embedded system based on monitoring system and PDA.This thesis is focused on research and analysis of some theory problems and key technologies in the embedded Linux operating system used on the ARM9 platform. It discusses kernel's cut-out, the design of kernel bootloader program, the design and implement of Root file system, the development and debugging of other key technologies in detail.By taking the platform of ARM9 for example, the paper systematically describes how to transplant MTD driver to the platform . Finally the detailed design and the implement of the drivers of CAN bus, ADC and DAC are discussed.
