[0028] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present application. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present application. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present application.

[0029] The terms used herein are merely for describing specific embodiments and are not intended to limit the present application. The terms "including", "comprising", etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0030] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0031] In the case of using expressions such as "at least one of A, B, and C", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but not be limited to a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0032] In modern information technology ecosystems, there are a wide variety of devices, including servers, desktop computers, embedded devices, Internet of Things devices, etc. The firmware versions, function interfaces, and communication protocols of these devices are diverse, making the firmware upgrade work extremely complex. The same firmware update operation may encounter problems such as configuration incompatibility and update failure on different devices, which poses a huge challenge to device management.

[0033] As the main bearer of social computing power, the operating efficiency of servers is crucial. In large-scale data centers, the stable operation of a large number of servers is crucial for the continuity and reliability of services. The stability of voltage regulation directly affects the performance and lifespan of servers. Therefore, it is necessary to upgrade the voltage regulation firmware in a timely manner to reduce server failures and downtime caused by power problems and improve the availability and operation and maintenance efficiency of servers.

[0034] The power supply requirements of different users for the device may vary. For example, some users who are sensitive to energy consumption may require a more energy-efficient voltage regulation scheme, while some users with extremely high performance requirements may need a faster and more accurate voltage regulation. Through firmware upgrade, the voltage regulation function can be customized according to the specific needs of users to provide personalized solutions.

[0035] Moreover, the security threats faced by the device are also increasing day by day. Vulnerabilities in the voltage regulation firmware can lead to device failures, data loss, and even security incidents. By upgrading the firmware in a timely manner, known security vulnerabilities can be repaired, enhancing the security and stability of the device.

[0036] In some critical application scenarios, such as the fields of finance, healthcare, and aerospace, the reliability of the device is of utmost importance. The upgrade of the voltage regulation firmware can optimize power management, reduce voltage fluctuations and anomalies, thereby improving the reliability and fault tolerance of the entire system.

[0037] In the related technology, the administrator can use a browser to access the IP address of the baseboard management controller for login, and click the selection button in the firmware management function area, manually select the previously downloaded firmware file and click the submit button. The baseboard management controller will upload the firmware file to the server and start writing, that is, start the voltage regulation firmware upgrade. After the upgrade is completed, the baseboard management controller will return a success message. After checking that the log is correct, a power-off failure is performed.

[0038] However, in the above voltage regulation firmware upgrade method, when the voltage regulation firmware is powered on, it will load some configurations from the node version manager into the register, and then the voltage regulation firmware will output the corresponding power supply strategy according to the register. The node version manager is an electronic storage device with a fusing technology, that is, each modification of the node version manager will consume a user area of the voltage regulation firmware. During the firmware upgrade process of the voltage regulation firmware, some auxiliary power is inevitably modified. Usually, after the voltage regulation firmware is upgraded, the entire server is powered on and off again. The entire operation and maintenance process is overly cumbersome. Especially in a computer room with multiple models, manually operating the power-off, whether remotely or on-site, will bring some risks and inconveniences.

[0039] In summary, in the related technology, the firmware upgrade is implemented through the baseboard management controller, which requires manual selection of the firmware. Before the upgrade, the entire machine needs to be powered off manually. The operation method is cumbersome and error-prone, resulting in low upgrade efficiency and difficult to meet the requirements of rapid upgrade.

[0040] Based on this, the present application provides an upgrade method for voltage regulation firmware, including: when the server power is off, in response to detecting a lower auxiliary power command from the baseboard management controller, setting the auxiliary circuit related to the voltage regulation firmware to be turned off, so that when the baseboard management controller detects that the auxiliary circuit is turned off, it upgrades the voltage regulation firmware to be upgraded to obtain the upgraded voltage regulation firmware, where the auxiliary circuit, the voltage regulation firmware to be upgraded, and the baseboard management controller are all set in the server, and the lower auxiliary power command is generated by the baseboard management controller based on the firmware upgrade instruction for the voltage regulation firmware to be upgraded; in response to detecting an upper auxiliary power command from the baseboard management controller, setting the auxiliary circuit to the on state to run the upgraded voltage regulation firmware, where the upper auxiliary power command is generated by the baseboard management controller when it detects that the upgrade of the voltage regulation firmware to be upgraded is completed.

[0041] Figure 1 FIG. schematically shows an application scenario diagram of the upgrade method for voltage regulation firmware according to an embodiment of the present application.

[0042] As Figure 1 shown, the application scenario 100 according to this embodiment may include a baseboard management controller 101, a control device 102, voltage regulation firmware 103, and an auxiliary circuit 104 related to the voltage regulation firmware. The baseboard management controller 101 is connected to the voltage regulation firmware 103 through a serial communication protocol. An electrical connection is achieved between the baseboard management controller 101 and the control device 102. The voltage regulation firmware 103 is used to output the parameters of the auxiliary circuit 104. The control device 102 is used to perform a power-down or power-up operation on the auxiliary circuit 104 related to the voltage regulation firmware.

[0043] When the server power is off, after accessing the IP address of the baseboard management controller 101 using a browser, a firmware upgrade instruction indicating that the voltage regulation firmware 103 needs to be upgraded is sent to the baseboard management controller 101. After receiving the firmware upgrade instruction, the baseboard management controller 101 sends a lower auxiliary power command to the control device 102. The control device 102 performs a power-down operation on the auxiliary circuit 104 related to the voltage regulation firmware, causing the auxiliary circuit to turn off. At the same time, the control device 102 sets the auxiliary power state to the power-down prohibited startup state. The baseboard management controller 101 reads the power-down prohibited startup state from the control device 102 and upgrades the voltage regulation firmware 103.

[0044] After the baseboard management controller 101 detects that the upgrade of the voltage regulation firmware 103 is completed, it sends an upper auxiliary power command to the control device 102. The control device 102 performs a power-up operation on the auxiliary circuit 104 related to the voltage regulation firmware, causing the auxiliary circuit to turn on. At the same time, the control device 102 sets the auxiliary power state to the power-up allowed startup state.

[0045] It should be noted that the method for upgrading the voltage regulation firmware provided in the embodiments of the present application can be executed by the baseboard management controller 101 or by the control device 102.

[0046] The following will be based on Figure 1 the described scenario, and will Figures 2 to 4 describe in detail the method for upgrading the voltage regulation firmware of the disclosed embodiments.

[0047] Figure 2 FIG. schematically shows a flowchart of a method for upgrading voltage regulation firmware according to an embodiment of the present application.

[0048] As Figure 2 shown, the method 200 for upgrading the voltage regulation firmware of this embodiment includes operations S210 to S220.

[0049] In operation S210, when the server power is off, in response to detecting a lower auxiliary power command from the baseboard management controller, the auxiliary circuit related to the voltage regulation firmware to be upgraded is set to the off state, so that the baseboard management controller upgrades the voltage regulation firmware to be upgraded to obtain an upgraded voltage regulation firmware when detecting that the auxiliary circuit is off.

[0050] In operation S220, in response to detecting an upper auxiliary power command from the baseboard management controller, the auxiliary circuit is set to the on state to run the upgraded voltage regulation firmware.

[0051] According to an embodiment of the present application, the method can be applied to a control device. The control device is responsible for initializing and configuring some important components. For example, it can set the functions of some pins of the CPU to determine whether they are ordinary I / O pins or special function pins (such as memory access pins, etc.). The control device can also, according to different working modes of the server (such as high-performance computing mode, energy-saving mode, etc.), cooperate with the voltage regulation firmware to perform different initializations and configurations on each component of the system, thereby optimizing the system performance.

[0052] According to an embodiment of the present application, the voltage regulation firmware in an electronic device is responsible for regulating the input voltage to a stable output voltage to meet the requirements of different electronic devices.

[0053] According to an embodiment of the present application, the control device, the auxiliary circuit, the voltage regulation firmware to be upgraded, and the baseboard management controller are all provided on the server.

[0054] According to an embodiment of the present application, before upgrading the voltage regulation firmware to be upgraded, the server power supply can be monitored to determine whether the server power supply is turned off. For example, by monitoring the temperatures of the CPU, memory, fan, etc. of the server, it can be judged whether the server is in a power-off state.

[0055] According to an embodiment of the present application, when it is determined that the server is in a power-off state, the IP address of the baseboard management controller can be accessed through a browser for login to upload the upgrade file, and an upgrade instruction is sent to the baseboard management controller. After receiving the upgrade instruction, the baseboard management controller parses the upgrade file and, after verifying that the integrity of the upgrade file passes, sends a lower auxiliary power command to the control device.

[0056] According to an embodiment of the present application, the lower auxiliary power command can be generated by the baseboard management controller based on the firmware upgrade instruction for the voltage regulation firmware to be upgraded. It is a command for powering down the auxiliary circuit associated with the voltage regulation firmware to be upgraded. For example, if the voltage regulation firmware to be upgraded is associated with the auxiliary circuits of devices such as the CPU, memory, hard disk, and fan, the lower auxiliary power command is a command for powering down the auxiliary circuits of the CPU, memory, hard disk, fan, etc.

[0057] According to an embodiment of the present application, after the control device receives the lower auxiliary power command, it can pull down the pin of the power supply of the auxiliary circuit in the logic control unit according to a certain timing sequence, pull down the corresponding pin of the auxiliary circuit, realize the power-down operation of the auxiliary circuit, and set the auxiliary circuit to the off state.

[0058] According to an embodiment of the present application, the auxiliary circuit can be a circuit that is self-powered inside the server motherboard and is a circuit that still needs to be powered all the time even after the server is shut down. The auxiliary circuit can include a power management auxiliary circuit and a signal conversion and transmission auxiliary circuit.

[0059] According to an embodiment of the present application, the power management auxiliary circuit can include a power supply monitoring circuit and a power supply timing control circuit. The power supply monitoring circuit is to monitor the output voltage and current of each power supply in real time through the power management module. When abnormal situations such as overvoltage, undervoltage, or current overload occur in the voltage, a signal is sent in time to notify the control module of the motherboard to perform corresponding processing, such as cutting off the power supply, to protect other components on the motherboard. The power supply timing control circuit is to ensure that different components on the motherboard are powered on and off in a specific order and time. For example, power is supplied to the memory first, and then to the CPU, etc., to ensure that each component can be normally initialized and operate, and to avoid equipment failures or damages caused by incorrect power supply sequences.

[0060] According to an embodiment of the present application, the signal conversion and transmission auxiliary circuit may include a level conversion circuit and a signal buffering and amplifying circuit. Since different modules on the server motherboard may adopt different voltage standards, the level conversion circuit is used to convert one level signal into another level signal, enabling effective signal transmission and communication between devices with different voltage levels. For example, converting a 3.3V signal into a 1.8V signal for use by a specific module. The signal buffering and amplifying circuit buffers and amplifies some signals with a relatively long transmission distance or vulnerable to interference, enhancing the driving ability and anti-interference ability of the signal, ensuring that the signal will not be distorted or attenuated during transmission, and guaranteeing the accuracy and stability of data transmission. It is commonly used for signal transmission such as USB and network.

[0061] According to an embodiment of the present application, after detecting a lower auxiliary power command from the baseboard management controller, the control device may perform a power-down operation on the auxiliary circuit related to the voltage regulation firmware to be upgraded, that is, set the auxiliary circuit to the off state. And when the baseboard management controller detects that the auxiliary circuit is closed, the baseboard management controller parses the upgrade file, obtains the address of the voltage regulation firmware to be upgraded, and writes the upgrade file into the voltage regulation firmware to be upgraded, so as to realize the upgrade of the voltage regulation firmware to be upgraded and obtain the upgraded voltage regulation firmware.

[0062] According to an embodiment of the present application, the upper auxiliary power command is generated by the baseboard management controller after detecting that the upgrade of the voltage regulation firmware to be upgraded has been completed. It is a command for performing a power-up operation on the auxiliary circuit associated with the voltage regulation firmware.

[0063] According to an embodiment of the present application, in response to detecting an upper auxiliary power command from the baseboard management controller, the control device performs a power-up operation on the auxiliary circuit associated with the voltage regulation firmware, and at the same time sets the auxiliary circuit associated with the voltage regulation firmware to the on state to run the upgraded voltage regulation firmware.

[0064] According to an embodiment of the present application, after the control device receives the upper auxiliary power command, it delays for a certain time, for example, delays for 500 ms, and then raises the corresponding pins of the auxiliary circuit again according to a certain timing sequence to restore the auxiliary power, providing a stable power supply for the control circuit and the protection circuit.

[0065] According to an embodiment of the present application, running the upgraded voltage regulation firmware can take effect on the main circuit and the auxiliary circuit. The main circuit takes effect by turning on the main circuit; the auxiliary circuit can take effect through the process of first powering down the auxiliary circuit and then powering it up; thus, the upgraded voltage regulation firmware can be made to take effect.

[0066] According to an embodiment of the present application, in the case where the server power is turned off, a lower auxiliary power command sent from the baseboard management controller is received through a control device, and a lower auxiliary power operation is performed on an auxiliary circuit related to the voltage regulation firmware to be upgraded, so that the baseboard management controller upgrades the voltage regulation firmware to be upgraded when it detects that the auxiliary circuit has been turned off, and receives an upper auxiliary power command generated by the baseboard management controller after the upgrade is completed, and performs an upper auxiliary power operation on the auxiliary circuit to run the upgraded voltage regulation firmware. This solves the technical problems of manual power-off of the server and manual upgrade during the upgrade of the voltage regulation firmware in the related art, which may cause misoperations and low upgrade efficiency. Furthermore, it achieves the technical effect of automatically implementing the lower and upper auxiliary power operations, enabling the upgraded firmware to take effect without power interruption, reducing misoperations, and improving the reliability and upgrade efficiency of the upgraded firmware.

[0067] According to an embodiment of the present application, the baseboard management controller is electrically connected to a first register, and the first register is used to record command information representing lower auxiliary power information or upper auxiliary power information. The method further includes: reading the command information from the first register; determining that a lower auxiliary power command is detected when the command information represents lower auxiliary power information; and determining that an upper auxiliary power command is detected when the command information represents upper auxiliary power information.

[0068] According to an embodiment of the present application, the control device may include a programmable logic device, or may be other devices, such as an MCU (Micro Control Unit). Taking the control device as a programmable logic device as an example, the programmable logic device may include a first register, and the first register may be a write register. By electrically connecting the baseboard management controller to the first register, the command information of the lower auxiliary power command or the upper auxiliary power command received from the baseboard management controller can be written into the first register.

[0069] According to an embodiment of the present application, the programmable logic device reads the corresponding command information from the first register, and based on the read command information, determines whether to execute a lower auxiliary power command or an upper auxiliary power command on the auxiliary circuit corresponding to the voltage regulation firmware to be upgraded.

[0070] According to an embodiment of the present application, the first register of the programmable logic device stores the automatic lower auxiliary power command before the voltage regulation firmware upgrade and the automatic upper auxiliary power command after the upgrade, so as to be able to implement the automatic lower auxiliary power operation or upper auxiliary power operation on the auxiliary circuit based on the programmable logic device, such that there is no need for manual power-off during the voltage regulation firmware upgrade before and when the upgrade takes effect, improving the upgrade efficiency, reducing operation errors, and providing a stable power supply for the control circuit and the protection circuit.

[0071] According to an embodiment of the present application, the baseboard management controller is electrically connected to a second register, and the second register is used to record the auxiliary power state. The method further includes: in response to detecting that the auxiliary circuit has been turned off, setting the auxiliary power state of the second register to the power-down prohibited startup state; in response to detecting that the auxiliary circuit has been turned on, setting the auxiliary power state of the second register to the power-on permitted startup state.

[0072] According to an embodiment of the present application, the programmable logic device may further include a second register, and the second register may be a read register. After the programmable logic device performs a lower auxiliary power operation on the auxiliary circuit corresponding to the voltage regulation firmware to be upgraded and determines that the auxiliary circuit has been turned off, it may update the auxiliary power state of the voltage regulation firmware stored in the second register to the power-down prohibited startup state; after the programmable logic device performs an upper auxiliary power operation on the auxiliary circuit corresponding to the voltage regulation firmware to be upgraded and determines that the auxiliary circuit has been turned on, it may update the auxiliary power state of the voltage regulation firmware stored in the second register to the power-on permitted startup state.

[0073] According to an embodiment of the present application, by electrically connecting the baseboard management controller to the second register, the baseboard management controller can read the auxiliary power state of the feedback voltage regulation firmware from the second register, that is, the power-down prohibited startup state or the power-on permitted startup state.

[0074] According to an embodiment of the present application, when the auxiliary power state of the feedback voltage regulation firmware read is the power-down prohibited startup state, the upgrade of the voltage regulation firmware is realized; when the auxiliary power state of the feedback voltage regulation firmware read is the power-on permitted startup state, the upgraded voltage regulation firmware is run.

[0075] According to an embodiment of the present application, if the lower auxiliary power command received from the baseboard management controller is incorrect and causes the auxiliary circuit to power down, the control device needs to make a judgment. Only when the server is powered off can the corresponding power-down operation be performed on the lower auxiliary power command; and when the server power-on command is received, but the control device has not received the instruction that the voltage regulation firmware upgrade is completed, that is, the second register is in the power-down prohibited startup state and the voltage regulation firmware is still being upgraded, the server power is not allowed to be turned on to improve the reliability of the voltage regulation firmware upgrade.

[0076] Figure 3 The flowchart of the method for upgrading the voltage regulation firmware according to another embodiment of the present application is schematically shown.

[0077] As Figure 3 shown, the method 300 for upgrading the voltage regulation firmware in this embodiment includes operations S310 to S330.

[0078] In operation S310, with the server power off, in response to detecting a firmware upgrade instruction for the voltage regulation firmware to be upgraded, a lower auxiliary power command is sent to the control device, so that based on the control device, the auxiliary circuit related to the voltage regulation firmware to be upgraded is set to the off state.

[0079] In operation S320, when it is detected that the auxiliary circuit is off, the voltage regulation firmware to be upgraded is upgraded to obtain the upgraded voltage regulation firmware.

[0080] In operation S330, in response to detecting that the upgrade of the voltage regulation firmware to be upgraded is completed, an upper auxiliary power command is sent to the control device, so that based on the control device, the auxiliary circuit is set to the on state to run the upgraded voltage regulation firmware.

[0081] According to an embodiment of the present application, the method can be applied to a baseboard management controller. The auxiliary circuit, the voltage regulation firmware to be upgraded, the control device, and the baseboard management controller are all provided on the server.

[0082] According to an embodiment of the present application, the baseboard management controller can be connected to the voltage regulation firmware through a serial communication protocol to implement functions such as monitoring and management, fault diagnosis and handling, and firmware upgrade.

[0083] According to an embodiment of the present application, for the monitoring and management function: after the connection is established and the test is passed, the baseboard management controller can use the serial communication protocol interface to monitor the working status of the voltage regulation firmware in real time, such as parameters such as output voltage, current, and temperature, and perform some basic management operations, such as adjusting the voltage output value and setting protection thresholds.

[0084] According to an embodiment of the present application, for the fault diagnosis and handling function: when a power-related fault occurs in the server, the baseboard management controller can connect with the voltage regulation firmware through the serial communication protocol to quickly obtain relevant fault information and diagnostic data to help technicians quickly locate and solve problems.

[0085] According to an embodiment of the present application, for the firmware upgrade function: when upgrading the voltage regulation firmware, the upgraded firmware can be safely and stably transmitted to the voltage regulation firmware through the serial communication protocol connection between the baseboard management controller and the voltage regulation firmware, and the upgrade operation can be performed to ensure the smooth progress of the upgrade process and the normal operation of the device.

[0086] According to an embodiment of the present application, the baseboard management controller can add two commands to be implemented. The two commands can include a write command and a read command. The write command is used to inform the control device whether to perform upper or lower auxiliary power on the auxiliary circuit. The read command is used to obtain whether the current auxiliary circuit is powered on or off.

[0087] According to an embodiment of the present application, when performing voltage regulation firmware upgrade, the server power supply can be monitored to determine that the server power supply is in the off state.

[0088] According to an embodiment of the present application, the IP address of the baseboard management controller can be accessed through a browser for login and upload of the upgrade file, and an upgrade instruction is sent to the base management controller. After receiving the upgrade instruction, the baseboard management controller parses the upgrade file and, after verifying the integrity of the upgrade file, sends a lower auxiliary power command to the control device.
