[0032] First, let’s explain the terms involved in this application:

[0033] Integrated Circuit Bus: I2C (Inter-Integrated Circuit) is a serial communication bus that uses a multi-master-slave architecture to facilitate communication between motherboards, embedded systems or mobile phones and peripheral device components.

[0034] Power supply unit (PSU) is a key component in electronic devices. It is responsible for converting AC power into DC power required by the device, providing a stable power supply for various components of devices such as computers or servers.

[0035] Baseboard Management Controller: A baseboard management controller (BMC) is a microcontroller system that manages and monitors the server's hardware status, such as temperature, fan speed, and voltage, and can perform remote control and diagnostic functions.

[0036] In order to solve the problem of reduced efficiency of production servers in related technologies, the embodiments of the present application propose the following technical concepts: the inventor considers obtaining the integrated circuit bus addresses of multiple power supply units through a baseboard management controller, sending firmware update instructions to the power supply units by broadcasting, and the power supply units enter the firmware update mode according to the firmware update instructions. Multiple power supply units simultaneously perform firmware updates on the data blocks to be updated, generate firmware update information, generate an exit update instruction through the baseboard management controller, and the power supply units exit the firmware update mode. Compared with related technologies, the firmware of multiple power supply units is upgraded at the same time, saving firmware update time.

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] In conjunction with the specific application environment architecture or specific hardware architecture on which the execution of the firmware update method of the power supply unit depends, the specific application environment architecture or the specific hardware architecture is described herein.

[0039] refer to Figure 1 , Figure 1 Schematic diagram of an application scenario of the firmware update method of the power supply unit provided in the embodiment of the present application. Figure 1 As shown, the scenario includes: a baseboard management controller 101 and multiple power supply units 102 .

[0040] The baseboard management controller 101 is connected to the plurality of power supply units 102 via an integrated circuit bus.

[0041] Specifically, the baseboard management controller 101 obtains the integrated circuit bus addresses of multiple power supply units 102, generates a firmware update instruction, and sends the firmware update instruction to multiple power supply units 102. The power supply unit 102 enters the firmware update mode according to the update instruction, and receives the data block to be updated sent by the baseboard management controller 101, performs firmware update, and sends the generated multiple firmware update information to the baseboard management controller 101. The basic management controller 101 generates an exit update instruction according to the firmware update information, sends the firmware update instruction to the power supply unit 102, and the power supply unit 102 exits the firmware update mode.

[0042] Figure 2 A flowchart of a method for updating the firmware of a power supply unit according to an embodiment of the present invention is shown in FIG. Figure 2 As shown, an embodiment of the present application provides a method for updating the firmware of a power supply unit, and the method is described in detail as follows:

[0043] S201: Obtain integrated circuit bus addresses of a plurality of power supply units to be updated.

[0044] In this embodiment, the baseboard management controller and the multiple power supply units are in an I2C bus architecture, and one baseboard management controller master device is connected to multiple power supply unit slave devices.

[0045] In this embodiment, the baseboard management controller is a master node, and the multiple power supply units to be updated are slave nodes. The master node communicates with the slave nodes in a broadcasting manner.

[0046] In this embodiment, the multiple power supply units are of the same type.

[0047] S202: Generate a firmware update instruction according to the integrated circuit bus addresses of the power supply units to be updated.

[0048] In this embodiment, the baseboard management controller sets the power supply unit to be updated to the firmware update mode through the firmware update instruction.

[0049] S203: Sending a firmware update instruction to the plurality of power supply units to be updated, so that the plurality of power supply units to be updated enter a firmware update mode according to the firmware update instruction.

[0050] Specifically, the baseboard management controller sends the firmware update instruction to the integrated circuit bus address of the power supply unit. After receiving the firmware update instruction, the power supply unit enters the firmware update mode and responds to the I2C broadcast address of the baseboard management controller.

[0051] S204: Sending the data block to be updated to the multiple power supply units to be updated, so that the multiple power supply units to be updated perform firmware update according to the data block to be updated, and generating multiple firmware update information.

[0052] Specifically, the baseboard management controller sends the data block to be updated to the multiple power supply units to be updated through I2C broadcast.

[0053] S205: Receive multiple firmware update information sent by multiple power supply units to be updated.

[0054] In this embodiment, the firmware update information records the firmware update completion degree and firmware update error information in the power supply unit.

[0055] The firmware update error information indicates whether an update error occurs during the update process of the power supply unit.

[0056] Specifically, the power supply unit sends the updated firmware update information to the baseboard management controller through a broadcast response operation.

[0057] S206: Generate an exit update instruction according to the multiple firmware update information.

[0058] Specifically, a confirmation instruction is generated according to the firmware update information, and whether the power supply unit needs to be retransmitted is determined according to the confirmation instruction. The retransmitted data block is sent to the power supply unit that needs to be retransmitted, the number of retransmissions is recorded, and an exit update instruction is generated.

[0059] S207: Sending an exit update instruction to the plurality of power supply units to cause the plurality of power supply units to exit the firmware update mode.

[0060] Specifically, the baseboard management controller sends an exit update instruction to the integrated circuit bus address of the power supply unit, and the power supply unit exits the firmware update mode.

[0061] It can be seen from the above embodiments that the integrated circuit bus addresses of multiple power supply units to be updated are obtained through the baseboard management controller, and the firmware update instructions are broadcast to the multiple power supply units to be updated through the integrated circuit bus addresses. The power supply units enter the firmware update mode according to the firmware update instructions, perform firmware updates on the data blocks to be updated, and generate firmware update information. The baseboard management controller generates an exit update instruction according to the firmware update information. Compared with the related art, the firmware of multiple power supply units is updated simultaneously through the integrated circuit bus addresses, which saves firmware update time and improves the efficiency of production servers.

[0062] In one embodiment of the present application, step S206 includes:

[0063] S2061: Generate a confirmation instruction according to the multiple firmware update information.

[0064] In this embodiment, the confirmation instruction is to confirm the power supply unit that needs to be retransmitted.

[0065] S2062: Send a confirmation instruction to the multiple power supply units, so that the multiple power supply units determine whether the firmware needs to be retransmitted according to the confirmation instruction and generate retransmission information.

[0066] In this embodiment, the retransmission information includes the integrated circuit bus address of the power supply unit that needs to be retransmitted and the integrated circuit bus address of the power supply unit that does not need to be retransmitted.

[0067] S2063: Receive retransmission information sent by multiple power supply units.

[0068] Specifically, the retransmission information sent by the power supply unit is received by wireless communication.

[0069] S2064: Determine the power supply unit that needs to be retransmitted among the multiple power supply units based on the retransmission information. Specifically, the baseboard management controller obtains the integrated circuit bus address of the power supply unit that needs to be retransmitted and sends the retransmission data block to the integrated circuit bus address of the power supply unit that needs to be retransmitted.

[0070] S2065: Send the retransmitted data block to the power supply unit that needs to retransmit, so that the power supply unit that needs to retransmit performs a firmware replication operation, and records the number of retransmissions according to the firmware replication operation.

[0071] Specifically, the baseboard management controller sends the retransmission data block to the power supply unit that needs to be retransmitted by broadcasting. The power supply unit updates its firmware according to the retransmission data block and records the number of retransmissions.

[0072] S2066: Receive the retransmission count sent by the power supply unit that needs to retransmit.

[0073] Specifically, the number of retransmissions sent by the power supply unit is received by wireless communication.

[0074] S2067: Determine whether the number of retransmissions exceeds the retransmission limit.

[0075] Specifically, if the number of retransmissions does not exceed the retransmission limit, the unupdated data blocks are updated.

[0076] Specifically, if the number of retransmissions exceeds the retransmission limit, an error is marked and the retransmission ends.

[0077] S2068: If the number of retransmissions does not exceed the retransmission limit, an exit update instruction is generated.

[0078] Specifically, if the number of retransmissions does not exceed the retransmission limit, the baseboard management controller generates a query instruction to query whether the firmware of the power supply unit has been completely updated. If the firmware has been completely updated, an exit update instruction is generated.

[0079] It can be seen from the above embodiment that by sending a confirmation instruction to the power supply unit to be updated during the data block transmission process, the power supply unit to be updated determines whether the firmware needs to be retransmitted based on the confirmation instruction and generates retransmission information. The baseboard management controller obtains the power supply unit that needs to be retransmitted based on the retransmission information and sends the retransmission data block. The power supply unit that needs to be retransmitted overwrites the firmware, records the number of retransmissions, and sends the number of retransmissions to the baseboard management controller to determine whether the retransmission limit is exceeded and generate an exit update instruction to avoid the occurrence of erroneous data blocks during the firmware update process, thereby improving transmission efficiency.

[0080] In one embodiment of the present application, after step S2067, the following steps are further included:

[0081] S2069: If the number of retransmissions exceeds the retransmission limit, the retransmission data block is released.

[0082] Specifically, if the number of retransmissions exceeds a preset maximum number of retransmissions, the baseboard management controller skips the corresponding data block.

[0083] S2070: Acquire the released retransmission data block and the integrated circuit bus address of the power supply unit that exceeds the retransmission limit.

[0084] Specifically, the baseboard management control marks the released retransmission data block and the integrated circuit bus address of the power supply unit that exceeds the retransmission limit. After the power supply units are all updated, the power supply unit that exceeds the retransmission limit is individually retransmitted to update the firmware.

[0085] S2071: Generate an error log according to the released retransmission data block and the integrated circuit bus address of the power supply unit that exceeds the retransmission limit.

[0086] In this embodiment, the contents recorded in the error log include but are not limited to the integrated circuit bus address of the power supply unit that exceeds the retransmission limit, the released retransmission data block, and the error code.

[0087] S2072: Generate an exit update instruction according to the error log.

[0088] Specifically, after generating the error log, the baseboard management controller generates a query instruction to query whether the firmware of the power supply unit has been completely updated. If the firmware has been completely updated, an exit update instruction is generated.

[0089] As can be seen from the above embodiment, if the number of retransmissions exceeds the retransmission limit, the retransmitted data block is released, and the retransmitted data block and the integrated circuit bus address of the power supply unit that exceeds the retransmission limit are recorded in the error log to avoid program jamming caused by unlimited retransmission. The power supply unit that needs to be retransmitted is updated separately according to the error log.

[0090] In one embodiment of the present application, step S2068 includes:

[0091] S301: If the number of retransmissions does not exceed the retransmission limit, a query instruction is sent to the plurality of power supply units, so that the plurality of power supply units obtain corresponding update completion degrees.

[0092] Specifically, the baseboard management controller sends a query instruction by broadcasting to obtain the update completion degree of the power supply unit.

[0093] S302: Receive multiple update completion levels sent by multiple power supply units.

[0094] Specifically, the update completion degree sent by the power supply unit is received via wireless communication.

[0095] S303: If the multiple power supply units in the multiple update completion levels are all updated, generate an exit update instruction.

[0096] Specifically, if the multiple power supply units are all updated, an exit update instruction is generated; if there is a power supply unit among the multiple power supply units that has not been updated, the firmware update operation is continued.

[0097] From the above embodiment, it can be seen that if the number of retransmissions does not exceed the retransmission limit, a query command is sent to obtain the update completion degree of the power supply unit. If all power supply units are updated, an exit update command is generated to end the firmware update state, thereby avoiding resource occupation caused by repeated firmware updates.

[0098] In one embodiment of the present application, before step S201, the following steps are further included:

[0099] S401: Sending an initialization instruction to a plurality of power supply units to be updated, so that the plurality of power supply units to be updated generate initial state information according to the initialization instruction.

[0100] Specifically, the baseboard management controller performs an initialization operation on the power supply unit through an initialization instruction, and sets an initial state of the I2C communication interface.

[0101] S402: Receive initial status information sent by multiple power supply units to be updated.

[0102] Specifically, the initial state information sent by the power supply unit is received by wireless communication.

[0103] S403: Divide the firmware to be updated into multiple data blocks according to the initial state information.

[0104] Specifically, according to the size of the buffer storage space of the power supply unit, the firmware to be updated is divided into a plurality of data blocks that do not exceed the size of the buffer storage space.

[0105] S404: Generate corresponding calculation check codes according to the multiple data blocks.

[0106] Specifically, according to a preset byte length, the byte text of the data block is intercepted, and the byte text is encrypted to obtain an encrypted calculation check code.

[0107] It can be seen from the above embodiment that by initializing multiple power supplies to be updated, obtaining the initial status information of the multiple power supplies to be updated, and dividing the firmware to be updated into multiple data blocks according to the initial status information, the efficiency of data transmission processing is improved, and a corresponding calculation check code is generated according to each data block, and the integrity of the data transmission process is ensured by calculating the check code.

[0108] In one embodiment of the present application, step S404 includes:

[0109] S4041: According to a preset byte length, truncate byte texts of multiple data blocks.

[0110] Exemplarily, the intercepted byte text may be the last 2 bytes of the data block.

[0111] S4042: Encrypt the byte text according to a preset encryption rule to obtain encrypted byte text.

[0112] In this embodiment, encryption rules include but are not limited to symmetric encryption, asymmetric encryption, and homomorphic encryption.

[0113] S4043: Determine the encrypted byte text as a calculation check code.

[0114] Specifically, the baseboard management controller sends the data block to be updated and the corresponding calculated check code to the power supply unit via I2C broadcast.

[0115] It can be seen from the above embodiments that by intercepting the byte text of the data block, encrypting the byte text according to the preset encryption rules, and determining the encrypted byte text as the calculation check code, the security of data transmission between the baseboard management controller and the power supply unit is improved through the encrypted calculation check code.

[0116] In one embodiment of the present application, after step S404, the following steps are further included:

[0117] S405: Generate a test instruction according to the integrated circuit bus addresses of the multiple power supply units to be updated, wherein the test instruction includes a test data block and a calculation check code corresponding to the test data block.

[0118] Specifically, the baseboard management controller sends the test data block and the corresponding calculation check code to the power supply unit through I2C broadcast.

[0119] S406: Sending a test instruction to the plurality of power supply units to be updated, so that the plurality of power supply units to be updated write the test data block according to the calculated check code corresponding to the test data block, and generating a test result.

[0120] In this embodiment, the test results include two types of test results: success in writing the test data block and failure in writing the test data block.

[0121] S407: Receive test results sent by the multiple power supply units to be updated, and obtain communication status between the baseboard management controller and the multiple power supply units to be updated according to the test results.

[0122] Specifically, the test result sent by the power supply unit is received by wireless communication.

[0123] It can be seen from the above embodiment that after generating the calculation check code, a test instruction is generated, and the test data block and the corresponding check code are sent to the power supply unit to be updated, the test result is generated, and the communication status with the power supply unit is verified based on the test result to ensure that the communication channel is working normally.

[0124] In one embodiment of the present application, after step S207, the following steps are further included:

[0125] S501: Receive a firmware update request sent by a user terminal.

[0126] Specifically, a firmware update request sent by a user terminal is received by wireless communication.

[0127] S502: Generate a version query instruction according to the firmware update request.

[0128] In this embodiment, the content queried in the version query instruction includes but is not limited to the firmware name, firmware version number, and firmware update date.

[0129] S503: Sending a version query instruction to the power supply unit, so that the power supply unit obtains version data according to the version query instruction.

[0130] In this embodiment, the content recorded in the version data includes but is not limited to the firmware name, firmware version number, and firmware update date.

[0131] S504: Receive version data sent by the power supply unit, and generate a firmware update broadcast according to the version data.

[0132] Specifically, the firmware update date in the version data is obtained, compared with the latest firmware update date recorded in the baseboard management controller, the latest version of the firmware is obtained, and a firmware update broadcast is generated.

[0133] S505: Send a firmware update broadcast to the integrated circuit bus address of the power supply unit, so that the power supply unit updates the firmware version and generates an update result.

[0134] Specifically, the firmware update broadcast is sent to the integrated circuit bus address of the power supply unit by wireless communication.

[0135] S506: Receive the update result sent by the power supply unit, and send the update result to the user end.

[0136] Specifically, the update result sent by the power supply unit is received by wireless communication.

[0137] Specifically, the update result is sent to the client via wireless communication.

[0138] It can be seen from the above embodiments that by receiving a firmware update request sent by the user end, a version query instruction is generated according to the firmware update request, the power supply unit obtains version data according to the version query instruction, and the baseboard management controller generates a firmware update broadcast according to the version data, sends the firmware update broadcast to the integrated circuit bus address, updates the firmware version, and feeds back the update result to the user end. During the user's use, the firmware is updated in broadcast mode, which reduces the user's waiting time and improves the user experience.

[0139] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
