Example Embodiment

[0032] First, explain the core and foundation of the present invention:

[0033] (1) Parameter storage

[0034] When the BOOT program guides the upgrade, if it finds BOOTA5.Dat and other configuration files, it will read the polarity of the DDR, FLASH model, LCD display, headset holder, and configure the OS partition size and registry area in the file. Space size, FLASH partition size, CPU frequency setting, LOGO area size, format FLASH optional configuration, whether to enable dual backup of system boot, OEMINFO information required for matching maps and other related information, and store it in a FLASH In the place.

[0035] (2) Dynamic configuration

[0036] After the upgrade is completed, restart the computer, the BOOT program will read the DDR, FLASH and other information stored during the upgrade, and pass the parameters to the OS layer, and the OS will match the hardware through these parameters, and then boot.

[0037] (3) Configuration file

[0038] The following are examples...

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...
