Design Of The Hardware And Software Platform Of Vehicle Autonomous Navigation System Based On ARM9

Vehicle autonomous navigation system is an essential part of intelligent transportation. It combines user,road network,conveyance together as a whole system to maximize the usage of transportation infrastructure, lighten the traffic, improve the cosiness and security of the traveler, meanwhile ,it also can save energy,protect environment, meet the requirement of the technology trend.This paper is focus on the design of hardware and software platform. The central part of the hardware platform is S3C2410 processor, integrated with 64M SDRAM,64M NANDFLASH,LCD,Touch screen,GPS module and the interfaces such as USB,SD Card.On this hardware platform, we deeply discussed and resolved the task and difficult problem be confronted with the course of Linux and embedded GUI porting. Firstly researched the design ways and the implementation process of the boot loader which is used to boot the Linux. Secondly, showed the analyse of booting Linux and the process of transplanting, transplanted net device's driver successfully based on analyzing embedded Linux device's driver model, then analysed the file system's principle and made successfully the root file; at the end, analysed what the Qt/E's low level supported, described the process of the Qtopia4's cross compile in detail, and run the routine which the Qtopia4 self-bring with under this platform.
