Electronic device firmware updating method and system

Abstract

The invention discloses an electronic device firmware updating method and system. The electronic device has the network connection function. The method of the invention comprises the following steps: at start-up, entering a security update mode before the operating system is loaded; starting the network service functions of the electronic device in a safe mode, including starting to intercept a connection request; establishing network connection after intercepting the connection request, receiving an operation and maintenance instruction to the firmware data of the electronic device; and according to the operation and maintenance instruction, performing operations to the corresponding firmware data of the electronic device. The system comprises a firmware storing unit and an updating unit, wherein the updating unit contains a network module and a processing module. The system of the invention can update the electronic device firmware safely and easily, save the storage space of the hardware and reduce the waiting time of the user and the maintenance cost.

Description

technical field [0001] The invention relates to a method and system for updating firmware data of an electronic device, in particular to a method and system for updating firmware data of an electronic device with network connection function. Background technique [0002] Many existing electronic devices or computer devices can obtain firmware update programs through a network connection for correcting firmware errors or improving the stability and performance of the firmware. But be used in the firmware update method of computer device, for embedded system device or small-sized electronic device such as mobile phone, personal digital assistant, or because hardware is equipped with not enough to support firmware update, or compare the firmware update method of computer device will improve Due to the production cost, it cannot be fully applied to the complex firmware update method of the computer device. [0003] For example, in U.S. Patent No. 7,191,327 (Internet-enabled dev...

[0007] Of course, many embedded system devices or small electronic devices will use the GUI provided in the root file system (Root Filesystem) to update the firmware, but the premise of this update method is that the device has been turned on normally. Entering the operating system, if an abnormality occurs during the update process, such as a sudden power outage, or an error occurs on the device due to an incorrect update version, after the device is restarted, the firmware cannot cooperate with the normal operation of the hardware, that is, it cannot enter the operating system. The user cannot remedy or restart the interrupted firmware update operation, and can only send the device back to the repair manufacturer for repair, which causes inconvenience and waste of time for the user

In order to prevent the above situation from happening, some devices will normally store a spare operating system or root file system in their memory as a remedy for the main system damage, but this will inevitably occupy the memory of many devices space, form waste and increase manufacturing cost

[0008] Or some embedded system devices use the command line interface (CLI) to enter commands through the boot environment provided by RedBoot to update the firmware. The convenient operation method cannot be widely used in consumer electronic products

[0009] In the firmware update operation of consumer electronic products or embedded system devices, at least the above-mentioned shortcomings exist at present, which makes ordinary users dare not easily perform firmware update operations; and the update process cannot be guaranteed during the update operation. Whether it can be successfully completed, it is necessary to develop a solution that can allow ordinary users to easily perform firmware updates at any time in a safe environment, improve the stability of electronic devices and increase performance with low-cost configurations
