Embodiment Construction

[0021] The features and functions of a computer firmware burning device according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] figure 1 It is a structural diagram of a computer firmware burning device 100 according to the present invention. In order to illustrate this embodiment more clearly, figure 1 The computer 101 in the figure only shows the firmware burning device 100 and the target component 140 . Those skilled in the art of the present invention should know that the computer 101 may also include other components such as a central processing unit and a chipset, so details are not described here. The aforementioned target component 140 may be any programmable chip inside the computer 101 , such as a complex programmable logic device (complex programmable logic device, CPLD). The aforementioned target component 140 may also be any non-volatile memory that records firmware in...

Abstract

The invention aims to provide a firmware burning device of a computer, comprising a connector, a bottom board management controller and an isolating circuit. The firmware burning device is used for transporting firmware date to a target component to carry out burning motion, and the firmware date is provided by the bottom board management controller or an external electronic device. When connection among each chip, each chip group and other hardware devices in the computer multiplex a transmission interface, the burning motion of the external electronic device to the target component can generate an abnormal state by being interfered by noise. On the basis of the firmware burning device, when the external electronic device is coupled with the target component in the computer to carry out the burning motion, the isolating circuit cuts off transmission interfaces between the target component and other hardware so as to enable the burning motion not to be interfered by the noise.

Description

technical field [0001] The invention relates to a firmware burning device, in particular to a burning device which avoids noise interference when burning firmware (firmware) from the outside of a computer. Background technique [0002] Many chips and chipsets are currently used inside computers to assist in the operation of the system. In order to save hardware costs, a large number of programmable chips (programmable chips) are used. When the function of the programmable chip changes, the firmware of the target component can be updated through the internal device, effectively saving hardware costs. For operational convenience, the connection of an external electronic device can be used to update the firmware of the target component. [0003] Based on hardware cost considerations, different transmission interfaces may be multiplexed among chips, chipsets and other hardware devices. The access between the target component and other chipsets and hardware devices adopts the ...
