Description

[0001] The present application relates to the field of server technology, and in particular to a method and system for upgrading server firmware based on a mobile terminal. Background Art

[0002] With the rapid development of information technology in today's society, we are exposed to an increasing amount of information and data in our daily lives, especially in big data, cloud computing, and AI inference training calculations, which are carried out by servers. As the underlying hardware, servers are focused on improving stability, performance, and security, and major manufacturers are focusing on this. Furthermore, firmware is required for communication between hardware and the system, and the operating system can only recognize the hardware through firmware. Many functions and bug fixes require firmware, so faster and more efficient firmware upgrades are also a challenge.

[0003] With the continuous advancement of electronic technology, server firmware needs to be constantly upgraded. Each user's pre-assigned server firmware is batch upgraded by connecting a portable PC to the BMC serial port or using remote tools. On-site operators need to carry multiple devices and cables for connection operations, which increases the operator workload and cumbersome operation steps, resulting in frequent troubleshooting.

[0004] In addition, after multiple upgrades, the server's firmware, such as PCH and BOIS, may have different versions. Due to version compatibility issues, the upgrade may not be completed.

[0005] In another case, when a BMC exception occurs, the server firmware upgrade cannot be achieved, and the upgrade is interrupted and cannot be completed. Therefore, in some scenarios, especially when customers believe that fast server startup is more important than security, it is even more difficult to flexibly choose the firmware upgrade method based on efficiency and security.

DETAILED DESCRIPTION

[0019] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation.

[0021] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0022] See also Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the system for upgrading server firmware based on a mobile terminal of the present application.

[0023] The system for upgrading server firmware based on a mobile terminal includes a programmable logic device, which is connected to a communication unit, and the communication unit is connected to a mobile terminal; the programmable logic device is respectively connected to a first multiplexer and a second multiplexer, the first multiplexer is connected to a specific firmware unit, and the second multiplexer is connected to a baseboard management controller, and the first multiplexer and the second multiplexer are connected to open a hardware path between the baseboard management controller and the specific firmware unit through the second multiplexer.

[0024] A multiplexer (MUX) is an electronic circuit that converts multiple input signals into a single output signal. This circuit typically consists of multiple input ports, a control port, and an output port. It selects between the input ports, thereby converting multiple input signals into a single output signal.

[0025] Programmable logic devices can be CPLDs (Complex Programmable Logic Devices) or FPGAs (Field-Programmable Gate Arrays). Baseboard Management Controller (BMC) exceptions include abnormalities in the management network port, the BMC stopping responding, or being unable to perform its management tasks normally.

[0026] The communication unit includes at least one of an NFC unit, a Bluetooth unit, an RFID unit, and an NFC unit. The firmware unit includes at least one of a BOIS, a PCH, a CPLD, and a BMC.

[0027] Figure 2 This is a schematic diagram of an example of an embodiment of a system for upgrading server firmware based on a mobile terminal of the present application. Figure 2 As shown, the firmware units may be two firmware units: BOIS and PCH.

[0028] In special cases, the server startup priority is higher. For example, the CPLD will verify the firmware upgrade file downloaded by the BMC from the WEB page to ensure its security. However, the CPLD verification will cause the BMC response time to be too long, and the BMC upgrade is urgently needed; or problems may occur in areas not covered by the CPLD verification, such as dynamic areas, which will result in the situation where the upgrade cannot be performed even if the verification is passed. In view of the above problems, the system for upgrading server firmware based on the mobile terminal proposed in the embodiment of the present application opens up the hardware path between the BMC and the firmware unit to be upgraded, and sets a communication unit to establish a channel for obtaining third-party firmware upgrade files, so as to realize flexible selection of firmware upgrade methods according to the application scenario.

[0029] Furthermore, in order to ensure the compatibility of the firmware upgrade file with the firmware to be upgraded, as well as the version compatibility of the firmware upgrade, this application will classify the firmware units to be upgraded based on whether they have an upgrade sequence relationship.

[0030] For example, if the upgrade history log shows that the upgrade of firmware A requires the upgrade of firmware B, it can be determined that firmware A and firmware B have an upgrade priority relationship. For example, when firmware A is the BMC, firmware B is the CPLD. When firmware A is the BIOS, firmware B can be the CPLD and the BMC, which need to be upgraded in parallel.

[0031] By applying the system for upgrading server firmware based on a mobile terminal proposed in the above-mentioned embodiment of the present application, the embodiment of the present application can analyze the current status of the firmware unit and BMC that need to be upgraded in the current scenario and select the most appropriate upgrade method.

[0032] Example 1, Figure 3 This is a flow chart of a method for performing a firmware upgrade based on a mobile terminal upgrade server firmware system according to an embodiment of the present application. Figure 3 As shown, the steps for performing firmware upgrade based on the mobile terminal upgrade server firmware system include: S1: The programmable logic device reads the BMC operation data of the baseboard management controller and the firmware upgrade file of the mobile terminal to determine whether the BMC is abnormal through the BMC operation data and obtain information about the firmware upgrade file of the mobile terminal.

[0033] For example, BMC status, logs, sensor data, interface data, etc. can all be used to determine the BMC status.

[0034] S2: If the baseboard management controller is abnormal based on the BMC operation data, the process jumps to step S31; if the baseboard management controller is not abnormal based on the BMC operation data, the process jumps to step S34.

[0035] S31: predicting a first time taken by the baseboard management controller to complete the firmware unit to be upgraded under the BMC operating data condition.

[0036] For example, if the BMC stops responding, you can retrieve the BMC's historical operation log to determine the probability and average time it takes for the BMC to restart and respond. Alternatively, you can retrieve the BMC's historical operation log to determine the average time it takes for the BMC to recover after a network connection anomaly. This value can be added to the time it takes for the BMC to log in to the web and download the firmware upgrade file, which serves as the initial time.

[0037] S32: Calculate a second time taken to complete the firmware unit to be upgraded by retrieving the first firmware upgrade file of the mobile terminal.

[0038] The second time includes the duration of the connection stability detection between the mobile terminal and the server after the mobile terminal is connected through the communication terminal, and the duration of the firmware upgrade file transmission from the mobile terminal.

[0039] S33: Select a target path from the first upgrade path and the second path based on the size relationship between the first time and the second time; the first path is a hardware path between the programmable logic device and a specific firmware unit; the second path is a hardware path between the baseboard management controller and a specific firmware unit.

[0040] Continue to refer Figure 2 If the firmware unit is BOIS, the first path is programmable logic device-first multiplexer-BOIS; the second path is BMC-second multiplexer-first multiplexer-BOIS.

[0041] The specific implementation process of executing step S34 includes: S341: The programmable logic device selects the first path as the target path.

[0042] S342: The programmable logic device verifies the second target firmware upgrade file downloaded by the BMC to ensure the security of the second target firmware upgrade file.

[0043] S343: After selecting the first path, the programmable logic device sends an instruction to the baseboard management controller, waits for the baseboard management controller to log in to the web, downloads the second target firmware upgrade file, and the BMC receives and stores the second firmware upgrade file; S344: Taking over control of the baseboard management controller, verifying the second firmware upgrade file, and verifying by sending the firmware upgrade file to the specific firmware unit through the first path.

[0044] In one embodiment, executing step S33 includes the following sub-steps: S331: If the first time is greater than the second time, select the first path as the target path.

[0045] If the first time is greater than the second time, it means that the efficiency of downloading the firmware upgrade file from the mobile terminal is higher.

[0046] For example, if the communication unit is an NFC communication module, before the mobile device is placed close to the NFC tag to identify the server's hardware and firmware information, a connection stability test is performed between the mobile device and the server. This ensures that the Type-C cable is properly connected and the data transmission channel is unobstructed to avoid interruptions caused by connection problems during the identification and update process.

[0047] S332: The programmable logic device retrieves a firmware upgrade file from the mobile terminal, verifies the firmware upgrade file, and verifies the firmware upgrade file by sending the firmware upgrade file to the specific firmware unit through the first path.

[0048] When a BMC anomaly occurs, it is determined that downloading the firmware upgrade file from a mobile device is more efficient. This file is obtained from the mobile device and sent to the firmware unit to be upgraded via a designated channel, ensuring network security without accessing the customer network. This avoids security risks, protects sensitive customer information, and enhances trust. To address abnormal situations, if the customer network or BMC serial port anomalies occur, the system can quickly switch to independent operation to complete the upgrade, minimizing service interruption.

[0049] In another embodiment, executing step S33 may further include the following sub-steps: S33-1: If the first time is less than the second time, select the second path as the target path.

[0050] If the first time is shorter than the second time, it means that it is more efficient to wait for the BMC to resume responding before completing the firmware upgrade. For example, you can wait for the BMC to resume network connection before completing the firmware upgrade.

[0051] S33 - 2 : The baseboard management controller logs in to the Web and downloads a second target firmware upgrade file. The BMC receives and stores the second firmware upgrade file and sends the second firmware upgrade file to the specific firmware unit through the second path.

[0052] Since the BMC has already had an abnormality, in order to further improve efficiency, complete the firmware upgrade first and improve the stability of the firmware. The firmware upgrade file can be sent directly to the firmware unit to be upgraded through the second channel BMC, so as to achieve the purpose of quickly completing the firmware upgrade when the guest server startup priority is higher.

[0053] In Example 2, to further ensure the compatibility of the firmware upgrade file with the firmware to be upgraded, as well as the compatibility of the firmware upgrade versions, the present application embodiment also proposes a method for upgrading the server firmware based on a mobile terminal, the steps comprising: S21: The programmable logic device reads the BMC operation data of the baseboard management controller and the firmware upgrade file of the mobile terminal.

[0054] S22: If an abnormality occurs in the baseboard management controller based on the BMC operation data; S23: Predicting a first time taken by the baseboard management controller to complete the firmware unit to be upgraded under the BMC operating data condition.

[0055] S24: Calculate a second time taken to complete the firmware unit to be upgraded by retrieving the first firmware upgrade file of the mobile terminal.

[0056] S25: Compare the first integrity of the first firmware upgrade file and the second integrity of the second firmware upgrade file.

[0057] S26: Select a target path from the first upgrade path and the second path according to the relationship between the first time and the second time, and the relationship between the first completeness and the second completeness.

[0058] If the firmware unit to be upgraded includes multiple first firmware units with an upgrade priority relationship, a first integrity of the first firmware upgrade file and a second integrity of the second firmware upgrade file are calculated according to the upgrade priority relationship.

[0059] For example, if the firmware unit to be upgraded includes a BMC and a CPLD, calculating the integrity of the firmware upgrade file includes: when the versions of the BMC and CPLD are consistent, determining the integrity to be C; when the versions of the BMC and CPLD are inconsistent, determining the integrity to be D, where C>D.

[0060] For example, calculating the integrity of the firmware upgrade file may also include: querying historical information, determining the version information of the current firmware to be upgraded, if the difference between the version number of a certain firmware and the version number of the current firmware to be upgraded is less than a preset value, determining the integrity to be E, if the difference between the version number of a certain firmware and the version number of the current firmware to be upgraded is greater than a preset value, determining the integrity to be F, E>F.

[0061] Executing S26 specifically includes the following steps: S261: If the first time is greater than the second time, and the first integrity is greater than the second integrity, select the first path as the target path.

[0062] S262: If the first time is less than the second time, and the second integrity is greater than the first integrity, select the second path as the target path.

[0063] S263: If the first time is greater than the second time and the first integrity is less than the second integrity, or if the first time is less than the second time and the second integrity is less than the first integrity, send a confirmation message to the mobile terminal, obtain the user's command signal, and select the target path according to the user's command signal.

[0064] In one example of the present application, the process of executing the method for upgrading the server firmware based on the mobile terminal also includes the following process: As the programmable logic device retrieves the firmware upgrade file from the mobile device, a real-time progress display is added as the mobile device matches the server hardware information identified by NFC with the information in the mobile device's hardware library, allowing users to clearly understand the matching progress and status. When selecting the target firmware version for upgrade, in addition to the existing filtering function, more detailed version descriptions and compatibility tips are provided to help users make more informed choices.

[0065] After selecting the target path and sending the firmware upgrade file to the firmware unit, the server's hardware status and upgrade progress are monitored in real time during the upgrade process, and displayed on the mobile interface in the form of charts or dynamic bars for users to understand intuitively.

[0066] If the upgrade fails, not only will the failure log be transferred and displayed on the interface, but the possible reasons for the failure will also be automatically analyzed and corresponding solutions will be given.

[0067] After the upgrade is successful, in addition to feeding back information to the NFC module, the NFC module writes the new firmware information to the NFC tag and automatically generates an upgrade report, including version comparison before and after the upgrade, upgrade time and other detailed information for users to retain or share.

[0068] Add an exception handling mechanism throughout the entire process. For example, if NFC recognition fails within a certain period of time or the matching process is stuck, it will automatically retry or display an appropriate error message on the mobile terminal.
