Embedded type system and start-up load application method

Abstract

The invention provides an embedded type system and the startup loading method thereof. Two loading modules are used for backup for each other, thus improving the reliability of an embedded system. Specifically, the invention discloses an embedded type system, which comprises a guiding module, a first loading module and a second loading module, the guiding module is used for checking the first loading module, if normal, the first loading module is guided to startup; if damaged, the first loading module is restored by the first loading module. By the mutual backup of the two loading modules, the security of the system during upgrading process is fully guaranteed, even if one loading module is damaged during the upgrading process or damaged by other accidental reasons, the loading module can be restored from the other loading module, thus ensuring the normal use of the whole embedded system.

Description

technical field [0001] The present invention relates to an embedded system method, more specifically to a method for booting and loading an embedded system. Background technique [0002] With the continuous development of science and technology, embedded systems have been widely used. Embedded systems generally refer to non-PC systems, devices or equipment that have computer functions but are not called computers. It is a special-purpose computer system that is application-centric, software and hardware can be cut, and meets the comprehensive and strict requirements of the application system on function, reliability, cost, volume, and power consumption. Simply put, the embedded system integrates the application software and hardware of the system, which is similar to the working method of the BIOS in a PC. It has the characteristics of small software code, high automation, and fast response speed, and is especially suitable for systems that require real-time and multi-taski...

Problems solved by technology

[0009] Since the general embedded system has only one fixed Boot Loader module, and BootLoader plays a very important role in the process of starting the embedded system, once the Boot Loader module is destroyed, the system will not start normally.

In order to avoid this problem, some embedded systems now divide the Boot Loader into two parts, one part is the most basic Boot module, and the other part is the Loader module for upgrading. The Boot module itself is fixed, and this part does not change. It will be damaged, and the Loader module may be changed because the original function cannot meet the requirements and needs to be continuously upgraded or improved. Once the module is damaged during the process of downloading the upgrade file or there is a problem with the newly downloaded Loader module, the system cannot be upgraded. , if the problem is not fixed quickly, users are limited to very basic applications, which may render the system unusable
