Firmware upgrading system based on communication interfaces

Abstract

The invention discloses a firmware upgrading system based on communication interfaces and belongs to the technical field of electrons. A circuit structure comprises a communication interface module, a main controller module, a memory medium module and a mandatory upgrading module, wherein the main controller module comprises a main controller chip and a program firmware module. A user can obtain the latest firmware conveniently in real time, upgrade the system, timely eliminate various software bugs and acquire the latest functions during device operation, rights and interests of the user are guaranteed, simultaneously, operation in the upgrading process is convenient, and time of the user and a manufacture is not delayed due to upgrading of the firmware, so that the cost is saved. The program firmware module is composed of a guide module, an operation module and a backup module, can conduct upgrading and restoration of the firmware and provides a manual mandatory upgrading function, so that the real zero-risk upgrading is achieved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a firmware upgrading system based on a communication interface. Background technique [0002] The ISO 9241-210 standard defines user experience as "people's cognitive impressions and responses to a product, system or service that is used or expected to be used". Therefore, user experience is subjective, and it focuses on practical application. The supplementary explanation of the ISO definition has the following explanation: user experience, that is, all the feelings of the user before, during and after using a product or system, including emotions, beliefs, preferences, cognitive impressions, physiological and psychological reactions, behaviors and achievements and other aspects. In practice, there are three factors that affect user experience: system, user, and usage environment. The establishment of the field of user experience is precisely to comprehensively analyze an...

Problems solved by technology

[0006] At present, the general electronic products on the market do not have the function of firmware upgrade. When the product leaves the factory, the manufacturer writes a firmware, and then the product enters the market. This kind of product has a very serious problem. When the firmware is damaged or has a loophole, the user cannot In normal use of the product, the manufacturer can only recall the product and upgrade the firmware through a dedicated interface, and this upgrade method cannot be opened to users. This operation mode not only wastes a lot of manpower and financial resources, but also wastes users and It is very inconvenient to deal with a lot of time for manufacturers, and it will bring users a very poor user experience and leave a very bad impression on users

This electronic product has the fatal flaw that the firmware cannot be upgraded

[0007] Some other smart products, such as smart phones that are widely used now, provide a firmware upgrade function, but due to imperfect software algorithm processing, the firmware upgrade first receives all the firmware and caches it, and then verifies its validity. Directly use the new firmware to directly replace the current firmware, so the current firmware has been damaged when the upgrade starts, so if there is an unexpected power failure during the upgrade process or the upgrade fails due to firmware compatibility, the product will not be able to be used. This problem occurs, It is difficult for ordinary users to solve it by themselves, and they can only spend a lot of time sending it back to the original factory for processing. The risk of upgrading is very high

This way of handling firmware upgrades has caused many users to dare not perform firmware upgrades, or take great risks to upgrade

Although this method can upgrade the firmware, solve software vulnerabilities, and improve the user experience when using the product, the user experience during the upgrade process is very bad and the risk is too high, causing many users to refuse to choose to upgrade
