Internet of Things terminal upgrading method and device

Abstract

The invention relates to an upgrading method and device for an Internet of Things terminal. The upgrading device comprises a Boot firmware storage area, an App firmware storage area and an App firmware backup area. The MCU is connected with an external Flash; after the MCU is powered on, the MCU enters a Boot firmware storage area, Boot firmware is initialized, and after corresponding operation isexecuted, the MCU skips to an App address. Then the App is initialized, whether the firmware version number needs to be updated or not is judged according to the read flag bit, updating processing iscarried out, the processed firmware version number is sent to the server, whether upgrading is carried out or not is determined according to a server instruction, if upgrading is carried out, upgrading processing is carried out, and if not, the APP address is skipped to execute a service task. According to the method and the device, the Flash is managed in a partitioning manner, and is matched with the judgment of the starting program, so that the terminal firmware automatically rolls back under the condition that remote upgrading fails, local upgrading and online upgrading are supported, andthe problem of terminal crash caused by accidental errors during upgrading is solved. Besides, when firmware updating fails, the Boot program automatically completes firmware rollback operation by judging the flag bit, and normal operation of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to an upgrading method and device for an Internet of Things terminal. Background technique [0002] The Internet of Things (The Internet of Things) is the comprehensive application and high integration of a new generation of information technology, and it is the strategic high point of current economic development and technological innovation.
