Abstract
Porting operation system is the basis of embedded-system′s development.The conception of the embedded real-time operating system VxWorks BSP(Board Support Package),the VxWorks start-up flow and the memory layout is introduced firstly.Then the hardware members of the board EBD9200,and the design and step to realize the BSP for EBD9200 is presented,including the initialization of hardware and software,the design of several important drivers,and the download of the bootrom and the project image.Lastly,a tip is recommended to debug the bootrom and to be refered by operation system′s porting.
