Bootstrap starting method of embedded system

Abstract

The invention relates to a bootstrap starting method of an embedded system. The bootstrap starting method includes 101) starting a BOOT; 103) inspecting and judging whether configuration files exist at a designated position, entering a next step, otherwise entering 105); 104) writing parameters in the configuration files in a fixed memory in the system, guiding the parameter to enter an operating system (OS), and entering 106); 105) guiding the parameters stored in the fixed memory in the system to enter the OS; AND 106) configuring hardware for the OS according to the parameters. The bootstrap starting method of the embedded system breaks through a traditional thought, internalizes hardware configuration in a starting process, is guided by the BOOT to input the parameters to the OS, does not need to be compiled again, and solves the problem of hardware matching of the embedded system.

Description

technical field [0001] The invention relates to a software and hardware system of an intelligent electronic product, in particular to a method for starting an embedded system boot program (BOOT). Background technique [0002] In the embedded system, for different double rate synchronous dynamic random access memory (DDR), flash memory (FLASH) model, liquid crystal (LCD) display screen, polarity of the headphone socket, and the partition size of the configuration operating system (OS) , Registry area space size, FLASH partition size, CPU frequency setting, LOGO area size, formatting FLASH optional configuration, whether to enable system boot dual backup, "OEMINFO" information for customizing system attributes required for matching maps, etc. . At present, for different hardware, almost all companies in the industry use corresponding programmers, re-modify the code, and compile the corresponding program, that is, the recompilation method can achieve the purpose of matching ha...

AI Technical Summary

Problems solved by technology

[0003] 1. Increase the cost of research and development, because many programmers are required to modify the code and recompile;

[0004] 2. The efficiency of publishing production software is not high, because the code needs to be re-modified every time for different hardware, and every code change needs to be re-tested;

[0005] 3. Affected the speed of shipment
