Analysis and Design of Boot Loader on Embedded Electric power steering system

摘要

Electric power steering systems (EPS) assist the auto turning using the power supplied by electromotor. An EPS based on embedded processor and embedded operating system is developed. In this system, S3C2410X is adopted as CPU and Windows CE 5.0 is selected as RTOS. This paper gives a brief introduction of the hardware platform and the Boot loader. Designing an appropriate boot loader, which is a key step to develop an embedded system, is given in detail. The boot loader, the hinge connects hardware and OS, is made up of OEM startup code and main code mostly. At the same time, some configuration files should be edited, such as sources, makefile and Boot. bib. Validated by experiment, author can run the boot loader in the video surveillance system successfully, it can help to debug the system and download the OS image, and the method described in this text to develop a boot loader is available.
