The invention discloses an upgrade method and device for embedded system software, wherein the method comprises the following steps: after being launched by a terminal device, Loader analyzes each module file and the update operation information of each module file from the updated file of a new version; wherein the update operation information of each module file comprises a plurality of memory device operational orders; aiming at each module file, Loader conducts operation to the memory device in the terminal device according to each memory device operation indication in the update operation information of the module file and writes the module file into a specified memory address in the memory device. Loader is capable of conducting a series of operations to the memory device according to the update operation information of the module file, so that the purpose of writing the module file into the specified memory address is realized, requirements such as module file storage address changing are met, and flexibility of software updating is greatly increased accordingly.
Description
technical field [0001] The invention relates to embedded system technology, in particular to a method and device for upgrading embedded system software in terminal equipment. Background technique [0002] At present, embedded system software is widely used in the field of communication, industrial control, home smart devices, national defense, medical treatment and other fields. For example, mobile phones, smart TVs, set-top box terminal equipment, and handheld computers all use embedded systems to provide intelligent functions with better human-computer interaction performance. [0003] At present, the system software upgrade method based on OTA (Over-the-Air Technology, space download technology) is widely used in various terminal devices because of its convenience of upgrading; , such as WIFI, 3G, etc., automatically download OTA upgrade packages, and automatically upgrade embedded system software for mobile phones or set-top box terminal devices. [0004] At present, t...
