Description
Technical field
The present invention relates to server design of hardware and software technical field, especially a kind of USB interface-based principal and subordinate BMC firmwares
Upgrade method.
Background technology
With the fast development of server technology, people for BMC functional requirement more and more higher, more some customize
Function will be imported and used, along with the upgrading of BMC firmwares.And in the methods of upgrading, it is convenient similarly to require, to reduce
Maintenance cost.Tradition has two kinds, a kind of software upgrading interface provided by BMC to BMC firmware upgrade approach；It is another to pass through
Hardware interface directly carries out burning to BMC FLASH.Former approach is mostly upgraded by lan interfaces, but when in system
When occurring two and above BMC, lan interfaces simply may access main BMC for user, for the upgrading from BMC just
The mode for having to enter into laboratory access netting twine is upgraded to firmware, and upgrade method operation is complicated, and maintenance cost is high.
The content of the invention
It is real by hardware interface it is an object of the invention to provide a kind of USB interface-based principal and subordinate BMC firmware upgrade methods
Synchronous upgrading between existing principal and subordinate BMC, upgrade method is simple, and it is convenient that post-service device is safeguarded.
To achieve the above object, the present invention uses following technical proposals：
A kind of USB interface-based principal and subordinate BMC firmware upgrade methods, comprise the following steps：
S1, Web send upgrade command and received to main BMC, main BMC after upgrade command, are sent out by the synchronous channels of principal and subordinate BMC
Send upgrade command to from BMC, principal and subordinate BMC does synchronous upgrading and prepared；
S2, Web send firmware updating and are mirrored to main BMC, and main BMC is mirrored to by USB interface synchronized transmission firmware updating
From BMC；
S3, main BMC send refresh command to from BMC by the synchronous channels of principal and subordinate BMC, main BMC and from BMC synchronous refresh；
S4, main BMC and carry out reset operation respectively from BMC, enable and update firmware.
Further, when need to quantity be more than two when synchronizing firmware updating from BMC, main BMC output end
The control end for selecting chip with priority piece is connected, and priority piece selects the output end of chip same with multiple principal and subordinate BMC from BMC respectively
Walk channel connection.
Further, the synchronous channels of the principal and subordinate BMC include I2C EBIs or UART interface.
Further, in step S1, the upgrade command is the life for meeting I2C bus inferface protocols or UART interface agreement
Make file.
Further, in step S1, principal and subordinate BMC does synchronous upgrading preparation and specifically included：
Main BMC stops accessing main BMC flash process, and refresh process is started into refresh mode；
Stop accessing the process from BMC flash from BMC, refresh process is started into refresh mode.
Further, in step S2, main BMC is mirrored to from BMC fortune by USB interface synchronized transmission firmware updating and deposited.
Further, in step S3, the refresh command is the life for meeting I2C bus inferface protocols or UART interface agreement
Make file.
Further, in step S3, main BMC and specifically included from BMC synchronous refresh：
Main BMC fortune deposits refreshing and upgrading firmware image, and main BMC is by the SPI interface between main BMC, main BMC flash to master
BMC flash burning firmware updating mirror images；
Deposit refreshing and upgrading firmware image from BMC fortune, from BMC by from BMC, from the SPI interface between BMC flash to
From BMC flash burning firmware updating mirror images.
The beneficial effects of the invention are as follows,
The main BMC of the present invention transmits firmware updating mirror image to from BMC by USB interface, realizes the synchronization between principal and subordinate BMC
Upgrading, from BMC synchronous upgrading is needed for multiple, between principal and subordinate BMC plus it is a piece of select chip, realize and queued up from BMC, the present invention
Upgrade method it is simple, realize principal and subordinate BMC synchronously upgradings, it is convenient that post-service device is safeguarded.
Brief description of the drawings
Fig. 1 is the inventive method flow chart.
Embodiment
Embodiment one
As shown in figure 1, when server includes main BMC and one upgrading synchronous from BMC needs, USB interface-based principal and subordinate
BMC firmware upgrade methods, comprise the following steps：
S1, Web send upgrade command and received to main BMC, main BMC after upgrade command, pass through I2C EBIs or UART
Interface transmission meets I2C bus inferface protocols or the command file of UART interface agreement does synchronous upgrading to from BMC, principal and subordinate BMC
Prepare, specifically stop accessing main BMC flash process for main BMC, refresh process is started into refresh mode；Stop from BMC
The process from BMC flash is accessed, refresh process is started into refresh mode.
S2, Web send firmware updating and are mirrored to main BMC, and main BMC is mirrored to by USB interface synchronized transmission firmware updating
Deposited from BMC fortune.
S3, main BMC are sent by I2C EBIs or UART interface meets I2C bus inferface protocols or UART interface association
The refresh command of view is to from BMC, main BMC and from BMC synchronous refresh, and main BMC fortune deposits refreshing and upgrading firmware image, and main BMC passes through
SPI interface between main BMC, main BMC flash is to main BMC flash burnings firmware updating mirror image；Refreshing is deposited from BMC fortune to rise
Level firmware image, passes through from BMC, from the SPI interface between BMC flash to from BMC flash burning firmware updating mirrors from BMC
Picture.
S4, main BMC and carry out reset operation respectively from BMC, enable and update firmware.
Embodiment two
When server includes two and when synchronizing firmware updating from BMC of above quantity, USB interface-based principal and subordinate
BMC firmware upgrade methods, comprise the following steps：
S1, Web send upgrade command and received to main BMC, main BMC after upgrade command, and control sheet selects the output end of chip
Send chip selection signals to multiple control ends from BMC, after one selected from BMC, main BMC by this from BMC and main BMC it
Between I2C EBIs or UART interface send meet the command file of I2C bus inferface protocols or UART interface agreement to from
