In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
A kind of IC method for burn-recording embodiment one provided by the invention is introduced below, embodiment one is based on firmware management
Module realizes that the firmware management module is located on board.Board is a kind of printed circuit board, abbreviation pcb board, and when production has
Lock pin can be inserted in the slot of main circuit board (mainboard) of computer, for controlling the operation of hardware, for example display, adopt
Corresponding hardware capability can be realized after installing driver in the equipment such as truck.The purpose of the present embodiment is that consolidating source IC
Part is burnt on target IC, and burning, which refers to, is written IC or single-chip microcontroller for firmware to realize some basic functions.
Referring to Fig. 1, embodiment one includes:
Step S101: after the operation that upper layer operating system executes by the firmware burning of source IC into target IC, judge institute
Whether the communications status for stating source IC and the upper layer operating system is abnormal.
Wherein, upper layer operating system, that is, upper layer OS, it is worth mentioning at this point that, above-mentioned upper layer operating system executes consolidating source IC
Part burning into target IC operation detailed process are as follows: after board first powers on, firmware management module is to link block
Enabled instruction is sent, then above-mentioned source IC and above-mentioned target IC can be connected to one in response to the enabled instruction by starting module
It rises, last upper layer operating system can directly execute the operation by the firmware burning of source IC to target IC.
As described in step S101, after the above process, firmware management module judges upper layer operating system and source IC
Between communications status it is whether abnormal, specific judgment mode, which can be such that, is arranged two between firmware management module and source IC
Access, i.e. heartbeat link and truck, wherein heartbeat link is used to the heartbeat packet of source IC being transferred to firmware management module,
Firmware management module is allowed to know the operating status of source IC；Truck is used for the current number of particular register in the IC of source
Value is transferred to firmware management module, and then firmware management module judges source IC by comparing above-mentioned current value and referential data
Extremely whether (referential data is firmware management module in advance from upper layer operation system to communication link between the operating system of upper layer
What system acquired).To sum up, when firmware management module is not received by the heartbeat packet of source IC transmission within a preset time, and it is solid
When part management module determines that above-mentioned current value and referential data are inconsistent by comparison, so that it may obtain upper layer operating system with
The conclusion of communications status exception between the IC of source.
Step S102: if abnormal, enabled instruction is sent to link block, in order to which the link block is in response to described
Enabled instruction is attached the source IC and the target IC.
Above-mentioned link block also is located on board, and is directly controlled by firmware management module, can be selective
Execution interconnects target IC and source IC.
S103: Xiang Suoshu source IC of step sends burning instruction, in order to which the source IC is in response to the burning instruction execution
By the firmware burning of itself into the operation of the target IC.
A kind of IC method for burn-recording provided by the present embodiment is realized, this method based on the firmware management module for being located at board
Source IC and upper layer operating system can be judged after the operation that upper layer operating system executes by the firmware burning of source IC into target IC
Communications status it is whether abnormal, and send enabled instruction to realize connection source IC and target IC, so to link block when abnormal
Burning instruction is sent to source IC afterwards, so that source IC is executed the firmware burning of itself into the operation of target IC.
As it can be seen that by firmware management module by board it is in need carry out online burning IC manage concentratedly,
Firmware management module confirmation is after after the IC of burning, burning failure leads to not communicate with upper layer operating system under system, automatically into
Row treats the secondary burning of burning IC, eliminates the offline burning of dismantling that engineer treats burning IC, improves complete machine board
Adjustable.

Block receives extraneous control, executes the operation of the pressure burning to target IC.
Referring to fig. 2, embodiment two specifically includes:
Step S201: after the operation that upper layer operating system executes by the firmware burning of source IC into target IC, judge institute
Whether the communications status for stating source IC and the upper layer operating system is abnormal.
Step S202: if abnormal, enabled instruction is sent to link block, in order to which the link block is in response to described
Enabled instruction is attached the source IC and the target IC.
S203: Xiang Suoshu source IC of step sends burning instruction, in order to which the source IC is in response to the burning instruction execution
By the firmware burning of itself into the operation of the target IC.
Step S204: obtaining the program state of the source IC in real time, and send cue module for the program state, with
The program state is externally prompted convenient for the cue module.
Specifically, firmware management module sends cue module for program state by serial port module, then cue module
The program state is prompted to the external world.
Step S205: if the program state is burning failure, extraneous control instruction is received by serial port module, and
Pressure burning is carried out to the target IC according to the control instruction.
Specifically, the external world can be connected to above-mentioned serial port module by Serial Port Line, sent out to realize to firmware management module
Send control instruction.As a preferred embodiment, wireless module can be connected in serial port module, received so as to realize
