To achieve the above goals, the hardware and software on the server need to complement each other and be highly integrated.

[0003] A mature server product will inevitably go through repeated troubleshooting (Debug) testing phases, which often takes a long time. When a software bug occurs, it is generally solved by upgrading the firmware version.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] Next, a firmware version updating method provided by an embodiment of the present invention is described in detail. Figure 2 A flowchart of a firmware version updating method provided by an embodiment of the present invention, the method comprising:

[0054] S201: Receive a change instruction transmitted by a controller.

[0055] The firmware version refresh method provided in the embodiment of the present invention is applicable to the firmware upgrade of various commonly used flash memory components. Among them, the flash memory components may include BIOS Flash and BMC Flash. For the convenience of subsequent introduction, BIOS Flash and BMC Flash are used as examples for description.

[0056] In practical applications, a logic processing component and a storage component may be provided, and the firmware refresh of the flash memory component may be completed through the interaction between the logic processing component and the control component. The logic processing component may adopt a field programmable gate array (FPGA), the storage component may adopt an electrically erasable programmable read-only memory (EEPROM), and the controller may adopt a BMC.

[0057] When the firmware needs to be changed, the controller can send a change instruction to the logic processing component.

[0058] S202: Compare the firmware version corresponding to the change instruction with the original firmware version to obtain a difference file, and record the difference file to a storage component.

[0059] In order to reduce the time spent on generating firmware each time a firmware refresh operation is performed, a difference file of different versions may be stored in the storage component. The difference file contains data that differs between two versions.

[0060] In the embodiment of the present invention, for the convenience of description, the firmware and its corresponding version may be referred to as firmware version.

[0061] Considering that in actual applications, for the same type of flash memory components, the latest firmware version is often modified and improved on the basis of the previous firmware version, the difference file can be the difference data between two adjacent firmware versions.

[0062] Taking three different versions of firmware as an example, including a first firmware version, a second firmware version and a third firmware version, the difference file may include difference data between the second firmware version and the first firmware version, and difference data between the third firmware version and the second firmware version.

[0063] Different flash memory components have their own corresponding firmware versions. Accordingly, each flash memory component has its corresponding storage area in the storage component. In the embodiment of the present invention, the area used to store the difference file of BIOS Flash can be called BIOS area, and the area used to store the difference file of BMC Flash can be called BMC area.

[0064] Taking BIOS Flash as an example, when the firmware of BIOS Flash needs to be changed, the controller can send a BIOS Flash firmware change instruction to the logical processing component. After the logical processing component receives the BIOS Flash firmware change instruction sent by the controller, it can obtain the firmware version corresponding to the BIOS Flash firmware change instruction from the controller and obtain the original firmware version from BIOSFlash; and record the difference file to the BIOS area of ​​the storage component.

[0065] Taking BMC Flash as an example, when the firmware of BMC Flash needs to be changed, the controller can send a BMC Flash firmware change instruction to the logic processing component. After receiving the BMC Flash firmware change instruction sent by the controller, the logic processing component can obtain the firmware version corresponding to the BMC Flash firmware change instruction from the controller and obtain the original firmware version from the BMC Flash; and record the difference file to the BMC area of ​​the storage component.

[0066] S203: When a refresh instruction transmitted by the controller is received, a target difference file matching the flash instruction is read from the storage component.

[0067] The refresh operation may include performing an upgrade operation on the firmware on the flash memory component or performing a downgrade operation on the firmware on the flash memory component.

[0068] When the controller needs to perform a refresh operation on the firmware on the flash memory component, the logic processing component can obtain the firmware version currently stored on the flash memory component, and determine the target difference file that matches the flash instruction based on the version to be upgraded or downgraded by the refresh instruction.

[0069] For example, the firmware version currently stored on the flash memory component is the first firmware version, and the refresh instruction indicates that the firmware needs to be upgraded to the second version. At this time, the logic processing component can read the difference file corresponding to the second firmware version and the first firmware version from the storage component, and the difference file is the target difference file.

[0070] S204: Feedback the target file to the controller according to the file type corresponding to the refresh instruction, so that the controller can complete the firmware refresh operation on the flash memory component according to the target file.

[0071] When considering firmware upgrade or downgrade, the firmware can be upgraded or downgraded directly to an adjacent level, or the firmware upgrade or downgrade can be performed across multiple levels.

[0072] The controller will send a refresh instruction to the logic processing unit to obtain the target file required for the firmware upgrade or downgrade. In order to distinguish different types of refresh instructions, in the embodiment of the present invention, the instruction corresponding to the operation of directly upgrading or downgrading to the adjacent first level can be called a firmware refresh instruction, and the instruction corresponding to the operation of upgrading or downgrading the firmware across multiple levels can be called a firmware cross-level refresh instruction.

[0073] Taking the refresh instruction as a firmware refresh instruction as an example, the logic processing component can read the difference file that matches the firmware refresh instruction from the storage component; based on the current firmware version and the difference file, generate a target firmware version, and feedback the target firmware version to the controller, so that the controller can complete the firmware refresh operation on the flash memory component according to the target firmware version.

[0074] Taking the refresh instruction as a firmware cross-level refresh instruction as an example, in order to reduce the requirements on the processing performance of the logical processing component, the logical processing component can read multiple difference files that match the firmware cross-level refresh instruction from the storage component, and directly feed back the multiple difference files to the controller, so that the controller can generate a target firmware version based on the current firmware version and the multiple difference files; based on the target firmware version, complete the firmware refresh operation on the flash memory component.

[0075] Figure 3This is a hardware structure diagram of a firmware version refresh system, taking the flash memory components including BIOS Flash and BMC Flash, BMC as the controller, FPGA as the logic processing component, and EEPROM as the storage component as an example. Assume that the current FW version of the server is 1.0, and now the FW version needs to be upgraded to 2.0, and the online upgrade is performed using the BMC Web interface. When the BMC has a FW version refresh request, the BMC will send the 1.FW Change signal as a change instruction to the FPGA chip in advance. The FPGA chip determines whether to change the firmware version of the BIOS Flash or the BMC Flash by identifying the high and low levels of the FW Change signal. In actual applications, a low level can be used to indicate that the firmware version is changed on the BIOS Flash, and a high level can be used to indicate that the firmware version is changed on the BMC Flash.

[0076] FPGA selects the selected area through the high and low levels of the 1.FW Change signal. If the 1.FW Change signal is low, the BIOS Flash can be selected through the signal 2.BIOS Select, and the FPGA obtains the 1.0FW file from the BIOS Flash. Conversely, if the 1.FW Change signal is high, the BMC Flash can be selected through the signal 3.BMC Select, and the FPGA obtains the 1.0FW file from the BMC Flash. At the same time, the FPGA obtains the file with FW version 2.0 from the BMC through the signal 8.FPGA I2C. Then, the two version files are compared inside the FPGA chip, and the different contents of the two versions are saved in the form of difference files.

[0077] When executing the saving of the difference file, the FPGA can select the saving area of ​​the difference file through the high and low levels of the 1.FW Change signal. If the 1.FW Change signal is low, the difference files of different BIOS versions are saved to the BIOS storage area through the signal 4.BIOS Save. On the contrary, if the 1.FW Change signal is high, the difference files of different BMC versions are saved to the BMC storage area through the signal 4.BMC Save. After the comparison file is saved, the storage component can send the signal 7.FW Compare Done to the BMC, and the BMC completes the refresh operation of the FW2.0 version.

[0078] In the embodiment of the present invention, a difference file is generated each time a version of FW is upgraded, such as Figure 4A schematic diagram of implementing firmware version refresh based on difference files is provided in an embodiment of the present invention. Assuming that the firmware version includes four versions, namely 1.0-2.0-3.0-4.0, three difference files △T1, △T2, and △T3 will be generated accordingly. During the Debug test of the FW version, if you want to reduce the BIOS version from 4.0 to 3.0, the BMC will send a signal 6.FW Change Request to the storage chip to activate the storage component, and transmit the difference file △T3 in the BIOS storage area to the FPGA through the signal 9.FW I2C. The FPGA modifies the current version 4.0 to 3.0 according to the comparison file, and transmits the modified 3.0 target file to the BMC through the 8.FPGA I2C signal. Finally, the FW refresh of the BIOS Flash 3.0 version is completed through the BIOS SPI.

[0079] If you need to downgrade the version of FW4.0 to 2.0, you need to send the two difference files △T2 and △T3 in the storage component to the BMC at the same time. The BMC first downgrades the version 4.0 to 3.0 based on the comparison file of △T3, and then downgrades the version 3.0 to 2.0 based on the comparison file of △T2. In this way, the FW refresh across versions is achieved.

[0080] Similarly, when an upgrade operation is required in the refreshed FW, the operation is similar to the above method and will not be repeated here.

[0081] It can be seen from the above technical solution that the change instruction transmitted by the controller is received; the firmware version corresponding to the change instruction is compared with the original firmware version to obtain a difference file, and the difference file is recorded in the storage component. The difference file contains data with differences between the two versions. When the refresh instruction transmitted by the controller is received, the target difference file matching the flash instruction is read from the storage component; according to the file type corresponding to the refresh instruction, the target file is fed back to the controller, wherein the target file is a file obtained according to the target difference file. The controller can complete the firmware refresh operation of the flash memory component according to the target file. In this technical solution, by recording the difference files between different versions, the firmware version required for this refresh can be obtained according to the target difference file matching the flash instruction. The firmware refresh method is simple and easy to operate. When implementing the firmware refresh operation of the flash memory component, no additional burner is required, and no new firmware version needs to be generated for each refresh. The problem of repeatedly refreshing the firmware version in software Debug testing is solved, and the processing efficiency of the firmware version refresh is effectively improved.

[0088] Optionally, when receiving a BMC Flash firmware change instruction transmitted by the controller, the comparison unit is used to obtain a firmware version corresponding to the BMC Flash firmware change instruction from the controller and obtain an original firmware version from the BMC Flash; and record a difference file in a BMC area of ​​the storage component.

[0089] Optionally, when the refresh instruction is a firmware refresh instruction, the feedback unit is used to read a difference file that matches the firmware refresh instruction from the storage component; generate a target firmware version based on the current firmware version and the difference file, and feedback the target firmware version to the controller so that the controller can complete the firmware refresh operation on the flash memory component according to the target firmware version.

[0090] Optionally, when the refresh instruction is a firmware cross-level refresh instruction, the feedback unit is used to read multiple difference files that match the firmware cross-level refresh instruction from the storage component, and feed back the multiple difference files to the controller, so that the controller can generate a target firmware version based on the current firmware version and the multiple difference files; based on the target firmware version, complete the firmware refresh operation on the flash memory component.
