Step includes S421 as shown in Figure 4, wherein
S110：Pending equipment is connect with firmware management equipment.
S421：The value of setting Status Flag is read, and is determined residing for pending equipment according to the value of setting Status Flag
Pattern.
In the present example, it is the setting status flag value of itself to be read by pending equipment, and be based on setting state
Value of statistical indicant judges the pattern residing for itself.Wherein, when read set Status Flag as program state value when, pending equipment is then
Judge that itself is in burning pattern；When setting Status Flag as boot state value, pending equipment then judges it itself is to be in
Bootmode；When setting Status Flag as completion status value, then pending equipment is that firmware is completed in pending equipment
Burning and firmware guiding.
S130：When pending equipment is in burning pattern, the target firmware that firmware management equipment is sent, and burning are received
Target firmware.
Further, in another embodiment, it after pending equipment is completed to the burning of target firmware, that is, completes to incite somebody to action
After target firmware in firmware management equipment is burned onto the memory in pending equipment, meeting further will be in pending equipment
Setting status flag value is changed by program state value is set as boot state value, to indicate that currently pending equipment has completed firmware
Burning, in other words, to indicate that currently pending equipment enters bootmode from burning pattern.
It should be understood that after pending equipment completes the guiding to target firmware, meeting further will be in pending equipment
Setting Status Flag changed by boot state value and be set as completion status value, the pending equipment to indicate current has completed mesh
Mark the guiding of the burning and target firmware of firmware.
Each embodiment in conjunction with corresponding to Fig. 1 to Fig. 4 is learnt, when there are multiple pending equipment to need in a certain LAN
The burning for carrying out target firmware, since there is difference in the time of the access current local area network of different pending equipment, so each
It is a to wait for that recording device carries out the progress of burning and guiding and has difference, and in technical solution provided herein, it provides pair
Pending equipment is presently in the deterministic process of pattern, it is possible to preferably according to each pending equipment processing of itself into
Degree carries out the guiding of the burning either target firmware of target firmware.It is possible thereby to learn, firmware burning provided herein
Method the automatic paralleling burning mode of multiple pending equipment can be provided, and then improve the efficiency of hardware firmware burning.
Optionally, the method for firmware burning provided herein further comprises：Judging currently pending equipment
It, can be further by having been completed to this in the currently pending equipment of firmware management equipment feedback operation personnel when being bootmode
The burning of target firmware, if burning target firmware again, to override original target firmware.
When in one embodiment, as beyond the answer instruction from firmware management equipment in preset time, is not received, automatically
Acquiescence enters bootmode, completes the guiding to target firmware.
In another embodiment, when pending equipment receives the feedback command of firmware management equipment transmission, foundation refers to
Order is operated.
Optionally, in one embodiment, when some pending equipment or multiple pending equipment are reprocessed,
It only needs that the LAN where firmware management equipment is added again, executes the step as described in step S110 to step S130 again
Suddenly, the step of or described in embodiment as described above, you can reprocessing for processing equipment is treated in completion, you can by new mesh
Mark firmware burning is to waiting for overriding existing target firmware in recording device.
Optionally, technical solution provided by the present application further comprises：The case where being guided based on burning generates monitoring report
Text is sent to firmware management equipment.Wherein monitoring message is for judging whether pending equipment deposits in the process of burning and guiding
In exception, while it can also provide example certain data basis for research hardware burning guiding.
Refer to Fig. 5, flow diagram shown in another technical solution provided by the present application.Wherein, implementation shown in fig. 5
Example technical solution is the method for being illustrated firmware burning provided herein with firmware management equipment for main executive agent.
