Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0028] Such as figure 1 As shown, a method for wirelessly upgrading firmware in the case of power failure disclosed in this embodiment includes the following steps:

[0029] 1. When the system is normal, the MCU and RF chip are in low power mode with interrupt enabled;

[0030] 2. When the RF chip receives the request sent by the upgrade server through the wireless UART serial port, an interrupt is triggered, so that the MCU chip enters the upgrade interrupt processing routine;

[0031] 3. The upgrade processing routine judges according to the rec...

Abstract

The invention discloses a method and system for wirelessly upgrading firmware under the condition of power failure. The method includes the following steps that 1, when the system is normal, an MCU chip and an RF chip are in a low-power consumption mode; 2, when the RF chip receives a request sent by upgrading server side, interrupting is triggered, so that the MCU chip enters an upgrading interrupt processing routine; 3, the upgrading processing routine performs judgment according to the received request, when the request is an upgrading request, an upgrading mode is entered, and when the request is a non-upgrading request, the step1 is executed; 4, the upgrading processing routine determines the type of the firmware to be upgraded on a main board according to upgrading codes transmittedby the upgrading server side, and during upgrading, connection with the upgrading server side is constant to download an upgrading file; 5, after the firmware is upgraded successfully, an upgrading result is uploaded to the upgrading server side. Under the condition of power failure, all the firmware and a BIOS are upgraded in batches, a user does not need return the firmware to a factory for processing, and therefore the upgrading efficiency of the firmware is improved.

Description

technical field [0001] The invention relates to a method for upgrading firmware of a motherboard, in particular to a method and a system for wirelessly upgrading firmware in the case of power failure when a system fails. Background technique [0002] At present, with the improvement of computer performance and the development of network interactive applications, different types of computer viruses are also flooding and raging, threatening the safe use of computer systems. A virus-infected computer is prone to system paralysis; in severe cases, the virus will destroy the firmware information on the motherboard, such as modifying the voltage parameters of the motherboard, rewriting the BIOS settings of the read-only memory, etc., resulting in the infected computer being unable to boot and restart or The system is abnormal, so that the user cannot repair and maintain firmware information such as burning BIOS under the system, but can only return the motherboard to the factory f...
