Abstract

The invention provides an embedded file data updating method and system.The embedded file data updating method comprises the steps that after a system is initialized, a selector is operated to check an abstract digital directory to obtain a mapping path, and an application starting script under the mapping path is called to complete application starting; the application starting script calls a decompressor to perform background operation, an update package is obtained, the update package is decompressed based on the abstract digital directory under an update path, and data update is completed. Mathematical logic calculation is added on the basis that the embedded file system stores the update file, an update program is divided into a selector and a decompressor, the file system is prevented from being abnormal during update iteration in a dynamic mapping mode, and the seriality, compatibility and stability of update data are ensured.

Description

technical field [0001] The invention relates to the technical field of embedded data processing, in particular to a method and system for updating embedded file data. Background technique [0002] In embedded systems, especially in low-cost embedded systems, the update of device files and data is a routine operation of device maintenance, which requires high reliability and logic of the update method, otherwise it will cause unpredictable batch products Loss. [0003] Usually, because the system resources of the embedded system are limited, or the system firmware flashing depends on the dedicated host computer environment, only the application program and data files are usually replaced. This update method of only updating non-system firmware becomes a restricted update. It is done with a directory or partition as a whole replacement object. For example, an additional directory needs to be created when updating, and the new files and programs are downloaded and decompressed...
