Abstract

The invention provides an operating system starting method. The method includes arranging a guide arranging label of am embedded micro processor, and selecting a starting mode; starting NOR FLASH after selecting a NOR starting mode; acquiring a main program entrance, and starting the operating system. By the aid of the method, the stability of load guide is improved, and the speed of load guide is increased.

Description

technical field [0001] The invention relates to a method for starting an operating system, in particular to a method for starting an operating system of an embedded system. Background technique [0002] Embedded system is the minimum simplified system based on practical application, widely used in industrial control, electronic equipment products, etc., such as real-time monitoring in intelligent transportation system. Since the startup of the embedded system and the loading of the program are all completed by the bootloader, the bootloader is very critical in the embedded system. If there is a problem with the bootloader or the application loaded by the bootloader, it may cause problems. It will cause the entire system to be paralyzed, even irreparable. Embedded BootLoader is usually stored on FLASH. As a kind of flash memory, NOR FLASH supports on-chip execution, and its reading speed is slightly faster than that of NAND, which is more suitable for small amount of code s...
