[0002] Firmware is the underlying, underlying code that serves as the foundation of a system and is crucial to server functionality and performance. Currently, most server firmware upgrades and upgrades rely on engineers using a burner fixture or system commands to individually upgrade and downgrade the firmware of each board and component. For example, in one approach, the corresponding chip, already soldered to the printed circuit board (PCB), is removed.

[0011] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0012] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0013] 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.

[0014] In the first embodiment, if Figure 1 As shown, a firmware upgrade method is provided, which is applied to a firmware upgrade device, wherein the firmware upgrade device is connected to a server, and the firmware upgrade method includes: determining whether the server is in a powered-on state; in response to the server being in a powered-on state, performing bidirectional authentication on the server and the firmware upgrade device to obtain a bidirectional authentication result; in response to the bidirectional authentication result being successful, determining an upgrade mode of the firmware upgrade device, wherein the upgrade mode includes at least an automatic mode and a manual mode; in response to the upgrade mode being the automatic mode, obtaining the current version number of the firmware and generating an upgrade instruction for the firmware based on the current version number, or determining the current running state of the firmware and generating a downgrade instruction for the firmware based on the current running state, wherein the upgrade instruction and the downgrade instruction include at least a target version number of the firmware; in response to the upgrade mode being the manual mode, receiving a user instruction and generating a firmware upgrade instruction or a firmware downgrade instruction based on the user instruction; and performing a corresponding upgrade operation or downgrade operation on the firmware based on the firmware upgrade instruction or the firmware downgrade instruction to change the current version number of the firmware to the target version number.

[0015] Specifically, two-way authentication is performed on the server and the firmware upgrading and downgrading device to ensure the authenticity of the identities of the server and the firmware upgrading and downgrading device, and to ensure that both parties are trustworthy; when the upgrading and downgrading mode of the firmware upgrading and downgrading device is automatic mode, an upgrade instruction or a downgrade instruction of the firmware is generated according to the current version number or the current running status of the firmware, which solves the technical problem of the low degree of automation of firmware updates and achieves the technical effect of improving the degree of automation of firmware updates; when the upgrading and downgrading mode of the firmware upgrading and downgrading device is manual mode, an upgrade instruction or a downgrade instruction of the firmware is generated according to the user's instructions, so that the firmware can be updated without triggering automatic upgrading and downgrading.

[0016] In specific implementation, Figure 2 As shown, in response to the server being powered on, a connection is established between the firmware upgrade device and the server baseboard management controller via the integrated circuit bus. In response to the successful connection establishment, the baseboard management controller performs a two-way authentication of the server and the firmware upgrade device, and then performs a firmware update operation. The two-way authentication of the server and the firmware upgrade device can be performed using an elliptic curve digital signature algorithm.

[0017] Furthermore, determining whether the server is in a powered-on state includes: obtaining a current voltage value of the server, and comparing the current voltage value with a preset voltage range, wherein the preset voltage range includes at least a first voltage range, a second voltage range, and a third voltage range; in response to the current voltage value being within the first voltage range, determining that the server is in a powered-on state; in response to the current voltage value being within the second voltage range, determining that the server is in a standby state; and in response to the current voltage value being within the third voltage range, determining that the server is in a powered-off state or a fault state.

[0018] In a specific implementation, for example, if the current voltage value is within 11.4V~12.6V; 4.75V~5.25V; 3.14V~3.46V, the server is in a powered-on state; if the current voltage value is within 4.75V~5.25V, the server is in a standby state; if the current voltage value is less than 1V, the server is in a powered-off state or a faulty state, for example, the power supply is not connected, the power supply is faulty, the mainboard short-circuit protection is triggered, or the baseboard management controller detects a serious abnormality, such as overvoltage / undervoltage.

[0019] Furthermore, bidirectional authentication is performed on the server and the firmware upgrade and upgrading device to obtain a bidirectional authentication result, including: generating a server authentication instruction, and sending the server authentication instruction to the server, while receiving a device authentication instruction generated by the server; performing authentication according to the device authentication instruction, obtaining a device authentication result, and returning the device authentication result to the server, while receiving a server authentication result returned by the server; in response to both the device authentication result and the server authentication result being successfully verified, determining that the bidirectional authentication result is a successful verification; in response to the device authentication result and / or the server authentication result failing to be verified, determining that the bidirectional authentication result is a failed verification.

[0020] Specifically, by performing two-way authentication on the server and the firmware upgrade device, the authenticity of the identities of the server and the firmware upgrade device is ensured, ensuring that both parties are trustworthy and establishing an end-to-end trust chain.

[0021] Furthermore, determining the upgrading and downgrading mode of the firmware upgrading and downgrading device includes: obtaining an upgrading and downgrading mode flag in the firmware upgrading and downgrading device, wherein the value of the upgrading and downgrading mode flag includes at least a first target value and a second target value; in response to the value of the upgrading and downgrading mode flag being the first target value, determining that the upgrading and downgrading mode of the firmware upgrading and downgrading device is an automatic mode; in response to the value of the upgrading and downgrading mode flag being the second target value, determining that the upgrading and downgrading mode of the firmware upgrading and downgrading device is a manual mode.

[0022] Specifically, by setting the upgrade mode flag of the firmware upgrade device to a first target value, the upgrade mode is automatic; and when the value is a second target value, the upgrade mode is manual. This allows for the generation of firmware upgrade instructions while also covering manual upgrades when automatic upgrades are not triggered and the firmware upgrade is required based on user needs.

[0023] In a specific implementation, the first target value is 0 and the second target value is 1.

[0024] Furthermore, the current version number of the firmware is obtained, and an upgrade instruction for the firmware is generated based on the current version number, including: obtaining the current version number of the firmware in the server, and a version information library of the firmware in the firmware upgrade and downgrade device, wherein the version information library includes at least multiple firmware files of the firmware and an upgrade policy flag of the firmware, and the value of the upgrade policy flag includes at least a first target value and a second target value; determining a target version number based on the current version number and the upgrade policy flag, wherein the target version number is greater than the current version number; comparing the target version number with the version numbers corresponding to the multiple firmware files to obtain a target firmware file corresponding to the target version number; and generating an upgrade instruction for the firmware based on the target firmware file.

[0025] Furthermore, based on the current version number and the upgrade policy flag, the target version number is determined, including: in response to the value of the upgrade policy flag being a first target value, determining that the version upgrade policy of the firmware is a step-by-step upgrade, and determining the new first-level version number of the current version number of the firmware as the target version number; in response to the value of the upgrade policy flag being a second target value, determining that the version upgrade policy of the firmware is a cross-level upgrade, and determining the latest version number of the firmware as the target version number.

[0026] Specifically, by setting the upgrade policy flag, the target version number satisfies the upgrade policy of the firmware corresponding manufacturer, thereby preventing the upgraded firmware from not being able to run normally.

[0027] In a specific implementation, if the firmware version upgrade strategy is step-by-step upgrade, and the firmware version number is v1.0 - v1.3 - v1.8 - v2.0, and the current version number is v1.3, the target version number is v1.8.

[0028] Furthermore, the current running state of the firmware is determined, and a firmware downgrade instruction is generated based on the current running state, including: determining the current running state of the firmware; in response to a compatibility error or a stability problem occurring in the current running state, obtaining the current version number of the firmware in the server, and a version information library of the firmware in the firmware upgrading and downgrading device, wherein the version information library includes at least multiple firmware files of the firmware and a downgrade policy flag of the firmware, and the value of the downgrade policy flag includes at least a first target value and a second target value; determining a target version number based on the current version number and the downgrade policy flag, wherein the target version number is smaller than the current version number; comparing the target version number with the version numbers corresponding to the multiple firmware files to obtain a target firmware file corresponding to the target version number; and generating a firmware downgrade instruction based on the target firmware file.

[0029] Furthermore, based on the current version number and the downgrade policy flag, the target version number is determined, including: in response to the value of the downgrade policy flag being the first target value, determining that the firmware version downgrade policy is a step-by-step downgrade, and determining the old version number of the current version number of the firmware as the target version number; in response to the value of the downgrade policy flag being the second target value, determining that the firmware version downgrade policy is a prohibition of downgrade, and generating an alarm message that a compatibility error or stability problem occurs on the server.

[0030] Specifically, by setting the downgrade policy flag, the target version number satisfies the downgrade policy of the firmware corresponding manufacturer, thereby preventing the downgraded firmware from not being able to operate normally.

[0031] Furthermore, the value of the downgrade policy flag also includes at least a third target value, and the firmware downgrade and upgrade method also includes: in response to the value of the downgrade policy flag being the third target value, determining that the firmware version downgrade policy is cross-level downgrade, and determining the old first-level version number of the current version number of the firmware as the first intermediate version number; performing a downgrade operation on the firmware according to the first intermediate version number, and determining the current running state of the firmware; in response to a compatibility error or a stability problem occurring in the current running state, determining the old first-level version number of the first intermediate version number of the firmware as the second intermediate version number; performing a downgrade operation on the firmware according to the second intermediate version number, and determining the current running state of the firmware; in response to the current running state being a normal state, determining the second intermediate version number as the target version number; in response to a compatibility error or a stability problem occurring in the current running state, determining the old first-level version number of the second intermediate version number of the firmware as the third intermediate version number, and performing a downgrade operation on the firmware according to the third intermediate version number until the current running state of the firmware is a normal state.

[0032] Specifically, downgrading is mainly to make the firmware version compatible with other firmware versions of the server. Therefore, when the value of the downgrade policy flag includes the third target value, and the value of the downgrade policy flag is the third target value, indicating that the firmware version downgrade policy is cross-level downgrade, the incompatibility between the downgraded firmware and other firmware of the server can be avoided by downgrading step by step.

[0033] In a specific implementation, the third target value is 2.

[0034] Furthermore, the firmware is downgraded according to the first intermediate version number, including: comparing the first intermediate version number with the version numbers corresponding to multiple firmware files to obtain a first intermediate firmware file corresponding to the first intermediate version number; generating a first downgrade instruction for the firmware according to the first intermediate firmware file; and performing a corresponding downgrade operation on the firmware according to the first downgrade instruction of the firmware to change the current version number of the firmware to the first intermediate version number.

[0035] Furthermore, generating a firmware upgrade instruction or a firmware downgrade instruction according to a user instruction includes: obtaining a target version number in the user instruction and a version information library of the firmware in the firmware upgrade and downgrade device, wherein the version information library includes at least multiple firmware files of the firmware; comparing the target version number with the version numbers corresponding to the multiple firmware files to obtain a target firmware file corresponding to the target version number; and generating a firmware upgrade instruction or a firmware downgrade instruction according to the target firmware file.

[0036] Furthermore, based on the target firmware file, a firmware upgrade instruction or a firmware downgrade instruction is generated, including: obtaining the current version number of the firmware and comparing the current version number with the target version number; in response to the current version number being less than the target version number, generating a firmware upgrade instruction based on the target firmware file; in response to the current version number being greater than the target version number, generating a firmware downgrade instruction based on the target firmware file.

[0037] In addition, the upgrade instruction and the downgrade instruction also include at least an expected update time period, and the firmware upgrade and downgrade method also includes: obtaining the size of the target firmware file, and determining the expected update time period of the target firmware file based on the size of the target firmware file; obtaining multiple idle time periods of the firmware, and calculating multiple corresponding idle time periods based on the multiple idle time periods; comparing the multiple idle time periods with the expected update time periods; in response to the current idle time period being greater than the expected update time period, determining the idle time period corresponding to the current idle time period as the pending update time period; sorting the multiple pending update time periods from large to small according to the idle time period, and determining the expected update time period based on the pending update time period ranked first, wherein the pending update time period ranked first includes the expected update time period; in response to the multiple idle time periods being less than or equal to the expected update time period, determining the start update time in the expected update time period of the firmware according to the user's selection.

[0038] Specifically, updating the firmware while the user is using it will interrupt the tasks the user is currently working on. Therefore, in order to make the firmware update more user-friendly, the firmware update time period is arranged during the firmware's idle time period, or the firmware is updated starting from the update start time selected by the user.

[0039] In a specific implementation, the idle time period of the firmware can be the idle time period of each day. For example, generally 0:00-4:00, 12:00-13:00, and 23:00-24:00 every day, and the estimated update time of the firmware is 2 hours, then 0:00-4:00 is determined as the estimated update time period; the estimated update time of the firmware is 4.5 hours, and the update cannot be completed within one day. Considering that 23:00-24:00 on the first day and 0:00-4:00 on the second day are continuous time periods, 23:00-4:00 can also be determined as the estimated update time period.

[0040] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 1At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0041] In a second embodiment, a firmware upgrade and downgrade device is provided, which is applied to a firmware upgrade and downgrade system. The firmware upgrade and downgrade system includes a server, such as Figure 3 As shown, the firmware upgrade and downgrade device is connected to the server via a universal serial bus interface provided on the server, as shown in FIG. Figure 4 As shown, the firmware upgrade and downgrade device includes: a core controller module, which is used to establish a connection between the firmware upgrade and downgrade device and the server through the integrated circuit bus signal in the universal serial bus interface, and is used to monitor the server information fed back by the integrated circuit bus in real time, wherein the server information includes voltage information, which is used to convert the server information obtained in real time and transmit the server information to the graphic data controller; a graphic data controller module, which is used to receive the server information transmitted by the core controller module, and transmit the server information to the graphic data display module after conversion; a graphic data display module, which is used to display the server information transmitted by the graphic data controller; a universal serial bus interface on the firmware upgrade and downgrade device side, which is used to output the server information obtained by the core controller module to an external receiving end or local storage space in real time, so as to troubleshoot the core controller module, debug the driver and burn it; a universal serial bus module, which is used to convert the asynchronous serial signal of the core controller into a universal serial signal, and report the core controller information to the server through the universal serial bus interface; as shown Figure 5As shown, the power module is used to convert the voltage obtained through the universal serial bus connector into the working voltage of other modules of the firmware upgrading and downgrading device; the first storage module is used to store multiple firmware files corresponding to the firmware; the second storage module is used to cache the working data in real time when the core controller module is in the working state, and is used to store the firmware files obtained by the core controller module from the first storage module during the firmware upgrading and downgrading process, so that the server baseboard management controller can upgrade and downgrade according to the firmware files in the second storage module; the button module is used to switch the upgrading and downgrading mode of the core controller module; the light group module is used to display the current status of the firmware upgrading and downgrading device, wherein, when the firmware upgrading and downgrading device is working, green represents that the firmware upgrading and downgrading device is working normally, red represents that the firmware upgrading and downgrading device has an abnormality, when the firmware upgrade is completed, green represents that the firmware upgrade is successful, and red represents that the firmware upgrade fails, when the firmware upgrading and downgrading device is only used to display server information, green represents that the server is working, red represents that the server has a fault, and off represents that the firmware upgrading and downgrading device is in standby state or non-powered state.

[0042] Table 1 Configuration information in the first storage module

[0043] ①The Head field and Magic Num field are the beginning and end of the configuration information. The 4-byte detection ensures that the first storage module has been correctly burned with the firmware information. ②Version field: The version information of the configuration information. The baseboard management controller program will check the version in the configuration information. When the configuration information space changes, it adapts and is compatible with the lower version configuration space through the version information. ③Type field: The firmware information is further identified through the Type field to achieve accurate adaptation to various firmware scenarios.

[0044] Table 2 Meaning of different bit positions in the Type field

[0045] Bit0: Checks whether the firmware has been signed. If so, the validity of the signature needs to be verified again. Bit1: The internal storage module of the baseboard management controller uses the low byte by default. This bit is used to adjust the byte order of the information read by the firmware. Bit2: The baseboard management controller has both primary and backup storage modules. This bit is used to determine the target storage module location for firmware upgrade. Bit3: Used to confirm whether to restart the system after the firmware upgrade.

[0046] ④Chip field: By configuring this information, the baseboard management controller is notified which memory chip in the basic input and output system, baseboard management controller, and programmable logic controller to upgrade; ⑤Public Key field and Md5 field, through the public key and information digest algorithm to complete the legality and integrity verification of the firmware; ⑥Data Loc field and Data Length field, these two fields are used to locate the position and size of the firmware in the storage module.

[0047] In the specific implementation, after the baseboard management controller completes the mounting of the first storage module through the universal serial link, it reads the first 46 bytes of the first storage module as configuration information. The baseboard management controller program completes the initialization operation before the firmware upgrade by reading and parsing the configuration information; the baseboard management controller reads the firmware content through the firmware location information, decrypts the firmware through the public key to ensure that the source of the data is normal, and decrypts the firmware again through the baseboard management controller's secret key to ensure that the firmware has not been illegally tampered with and to ensure the legitimacy of the firmware; by performing information summary algorithm verification on the firmware and comparing it with the standard value in the configuration information, the integrity of the firmware data is ensured to avoid data burning abnormalities during the firmware burning process.
