Description

Technical Field

[0001] The present invention relates to the field of server storage technology, and in particular to a voltage regulator firmware automatic updating method, device, equipment and medium. Background Art

[0002] After the server's VR FW (voltage regulator firmware) is updated, it is usually necessary to power off once for the new version to take effect. Previous practices include manually cutting off the AC power (AC) or controlling the VR chip's VCC (voltage control chip power supply) through a CPLD (complex programmable logic device) in the DC power sleep state (DC S5) to perform a slow restart after powering off.

[0003] Among them, the manual power-off operation will result in a failure to respond in time when in the customer's room, and waste human resources and costs; and the CPLD slow-start power-off and restart operation in the DC S5 state can achieve automatic update operations, but there are two disadvantages: first, the VCC of the VR chip is not synchronized with the VCC of the DRMOS (direct-driven metal oxide semiconductor) after slow start, which may cause leakage; second, for platforms such as Intel BHS AP, in the DC S5 state, the specific voltage (such as PVCCFA_EHV) of the VR chip power supply cannot be powered off.

[0004] Therefore, both of the above two voltage regulator firmware update operations have obvious defects and limitations. Summary of the invention

[0005] The purpose of the present invention is to provide a method, device, equipment and medium for automatically updating the firmware of a voltage regulator, aiming to solve the technical problem that the existing voltage regulator firmware update operation has obvious defects and limitations.

[0010] Obtaining a second CRC value from a CRC check register of the power chip;

[0011] Comparing the first CRC value with the second CRC value;

[0012] If the first CRC value matches the second CRC value, the BMC issues an instruction to shut down the PSU power supply and then restart it to make the updated voltage regulator firmware effective;

[0013] If the first CRC value does not match the second CRC value, the BMC reports an error and informs the voltage regulator that the firmware upgrade is unsuccessful.

[0014] In a possible implementation, the step of obtaining a first CRC value from the updated voltage regulator firmware includes:

[0020] The CRC check register is read through the BMC to obtain the second CRC value after actual burning.

[0021] In a possible implementation, if the first CRC value matches the second CRC value, the step of the BMC issuing an instruction to shut down the PSU power supply and then restart it so that the updated voltage regulator firmware takes effect includes:

[0022] After the BMC issues a shutdown command, the PSU power supply performs a restart operation after 10 seconds;

[0023] After the PSU power supply is powered on, the power supply of the integrated circuit of the voltage regulator performs a power-off restart operation to make the updated firmware of the voltage regulator effective.

[0024] In a possible implementation, if the first CRC value does not match the second CRC value, the step of the BMC reporting an error and informing the voltage regulator that the firmware upgrade is unsuccessful includes:

[0025] Sending an alert through the BMC to notify a technician that an error has occurred during the update process;

[0026] An error log is generated by the BMC to record specific error information.

[0027] In a possible implementation, the method further includes a safety verification step during the process of updating the voltage regulator firmware, the step comprising:

[0028] Before updating the voltage regulator firmware, verifying the digital signature of the update package by the BMC to ensure the integrity and authenticity of the update package;

[0029] If the digital signature verification fails, the BMC reports an error and terminates the update process;

[0030] If the digital signature verification is successful, the update operation of the voltage regulator firmware continues.

[0031] In a possible implementation, the method further includes a remote management step, which includes:

[0032] Sending an update instruction and a voltage regulator firmware update package to the BMC via a remote management system;

[0033] Automatically perform an update operation through the BMC;

[0034] During or after the update, the update status and result feedback are received through the remote management system.

[0041] The second judgment unit is configured to, if the first CRC value does not match the second CRC value, cause the BMC to report an error and inform the voltage regulator that the firmware upgrade is unsuccessful.

[0042] A third aspect of the present application provides a computer device, characterized in that the computer device includes a memory and a processor, the memory stores a computer program, and the processor implements the method described in the first aspect when executing the computer program.

[0043] A fourth aspect of the present application provides a computer-readable storage medium, wherein the storage medium stores a computer program, wherein the computer program includes program instructions, and when the program instructions are executed by a processor, the method described in the first aspect above can be implemented.

[0059] Embodiments of the present application provide a method, apparatus, device and storage medium for automatically updating firmware of a voltage regulator.

[0060] The executor of the voltage regulator firmware automatic update method may be the voltage regulator firmware automatic update device provided in the embodiment of the present application, or a computer device integrating the voltage regulator firmware automatic update device, wherein the voltage regulator firmware automatic update device may be implemented in hardware or software, the computer device may be a terminal or a server, and the terminal may be a smart phone, a tablet computer, a PDA, or a laptop computer, etc.

[0061] Figure 1 This is a flow chart of a method for automatically updating the firmware of a voltage regulator provided in an embodiment of the present application. Figure 1 .like Figure 1 As shown, the method includes the following steps S110-S160:

[0062] S110, updating the voltage regulator firmware in the power chip through the BMC;

[0063] Specifically, before updating the voltage regulator firmware, first, you need to make sure that the motherboard supports the BMC (Baseboard Management Controller) function. Next, download the voltage regulator firmware update file that is suitable for the current power chip. This can usually be obtained from the motherboard manufacturer's official website or related technical support channels. Then, upload the voltage regulator firmware update file to the motherboard through the BMC's web interface, DOS environment, or the update tool under the system, and start the update process. During the update process, the BMC will control the operation of the power chip to ensure the smooth update of the voltage regulator firmware.

[0064] S120, obtaining a first CRC value from the updated voltage regulator firmware;

[0065] Specifically, CRC (Cyclic Redundancy Check) is an algorithm used to detect errors in data transmission or storage. After the voltage regulator firmware is updated, the BMC extracts the CRC value from the updated voltage regulator firmware as the first CRC value. This CRC value represents the integrity of the voltage regulator firmware data.

[0066] S130, obtaining a second CRC value from a CRC check register of the power chip;

[0067] Specifically, the power chip usually contains a CRC check register for storing the CRC value of the current voltage regulator firmware. The BMC reads the value in this CRC check register as the second CRC value. This value is used to compare with the first CRC value to verify whether the update of the voltage regulator firmware is successful.

[0068] S140, comparing the first CRC value with the second CRC value;

[0069] S150: If the first CRC value matches the second CRC value, the BMC issues an instruction to shut down the PSU power supply and then restart it, so that the updated voltage regulator firmware takes effect;

[0070] Specifically, if the CRC values ​​match, the BMC will issue an instruction to shut down the PSU (Power Supply Unit) and then restart it, so that the updated voltage regulator firmware can take effect and ensure the normal operation of the motherboard and power supply system.

[0071] S160: If the first CRC value does not match the second CRC value, the BMC reports an error and informs the voltage regulator that the firmware upgrade is unsuccessful.

[0072] Specifically, if the CRC value does not match, the BMC will report an error and inform that the voltage regulator firmware upgrade was unsuccessful. At this point, the user needs to re-download the voltage regulator firmware update file and try the update process again. At the same time, you can also check the connection and status of the motherboard and power system to ensure that there is no hardware failure that caused the update failure.

[0073] In summary, this voltage regulator firmware automatic update method realizes the automated update process through BMC and ensures the integrity and accuracy of the voltage regulator firmware through the CRC check mechanism. This can not only improve the stability and security of the motherboard and power supply system, but also simplify the voltage regulator firmware update process and reduce the risk of errors.

[0074] like Figure 2 As shown, in a more specific embodiment, executing step S120 further specifically includes executing steps S121-S122:

[0075] S121, calculating, by the BMC, the first CRC value before the voltage regulator firmware is burned;

[0076] S122. Save the first CRC value as metadata in the voltage regulator firmware.

[0077] Specifically, before the voltage regulator firmware is burned (i.e., updated), the BMC will first read the data of the current voltage regulator firmware. Then, the BMC will use the built-in CRC calculation algorithm to perform CRC calculation on the data of the current voltage regulator firmware, thereby generating a CRC value as the first CRC value. After generating the first CRC value, the BMC will save it as metadata in the voltage regulator firmware. Among them, metadata refers to additional information associated with the firmware file (voltage regulator firmware), which describes the properties of the firmware file itself or data used to verify its integrity and correctness. In summary, saving the first CRC value as metadata in the voltage regulator firmware can avoid the need to recalculate the CRC value after the update. This simplifies the update process and reduces the use of computing resources.

[0078] like Figure 3 As shown, in a more specific embodiment, executing step S130 further specifically includes executing steps S131-S133:

[0079] S131, calculating the second CRC value after the voltage regulator firmware is burned through the power chip;

[0080] Specifically, after the voltage regulator firmware is burned, the power chip receives and processes the burned voltage regulator firmware data. The power chip has a built-in CRC calculation module, which performs CRC calculation on the received voltage regulator firmware data to generate a CRC value as the second CRC value.

[0081] S132, storing the second CRC value in the CRC check register;

[0082] Specifically, after the calculation is completed, the power chip will store the second CRC value in its internal CRC check register. The CRC check register is a special register in the power chip for storing CRC values ​​for subsequent data integrity verification.

[0083] S133: Read the CRC check register through the BMC to obtain the second CRC value after actually burning.

[0084] Specifically, when the voltage regulator firmware data integrity needs to be verified, the BMC communicates with the power chip through a communication interface (such as I2C, SPI, etc.). The BMC sends a read instruction to the power chip to request to read the value in the CRC check register. After receiving the read instruction, the power chip sends the second CRC value in the CRC check register to the BMC.

[0085] like Figure 4As shown, in a more specific embodiment, executing step S140 further specifically includes executing steps S141-S142:

[0086] S141, after the BMC issues a shutdown command, the PSU power supply performs a restart operation after 10 seconds;

[0087] Specifically, when the BMC confirms that the first CRC value matches the second CRC value, that is, the voltage regulator firmware update is successful and the data integrity is verified, the BMC will issue an instruction to shut down the PSU power supply. After issuing the shutdown instruction, the BMC will start a timer and set it to 10 seconds to ensure that the PSU power supply has enough time to complete the shutdown operation and prepare for restart.

[0088] S142: After the PSU power supply is powered on, the power supply of the integrated circuit of the voltage regulator is powered off and restarted to make the updated firmware of the voltage regulator effective.

[0089] Specifically, after the timer expires, the PSU will perform a restart operation. This includes cutting off the current power supply and then restarting the power supply process. The restart operation ensures that the power supply system is restored to its initial state and provides a stable power supply environment for the updated voltage regulator firmware.

[0090] like Figure 5 As shown, in a more specific embodiment, executing step S150 further specifically includes executing steps S151-S152:

[0091] S151, sending an alarm through the BMC to notify the technician that an error has occurred in the update process;

[0092] Specifically, when the BMC detects that the first CRC value does not match the second CRC value, that is, there is data corruption or change during the voltage regulator firmware update process, the BMC will immediately send an alarm notification. The alarm notification can be sent in a variety of ways, such as system logs, emails, text messages, or phone notifications, to ensure that technicians can quickly learn that an error has occurred in the update process.

[0093] S152: Generate an error log through the BMC to record specific error information.

[0094] Specifically, while sending the alert notification, the BMC also generates a detailed error log. The error log records the specific process of the voltage regulator firmware update, timestamp, first CRC value, second CRC value and other key information, as well as possible error causes or prompts. This information is crucial for technicians to troubleshoot and repair.

[0095] like Figure 6As shown, in a more specific embodiment, the process of executing step S110 also includes security verification steps S111-S113:

[0096] S111, before updating the voltage regulator firmware, verifying the digital signature of the update package by the BMC to ensure the integrity and authenticity of the update package;

[0097] Specifically, before updating the voltage regulator firmware, you first need to prepare the relevant digital certificate and public key. The digital certificate usually contains the public key and identity information of the signer, which is used to verify the identity of the signer and the validity of the public key. The signature algorithm (such as RSA, ECDSA, etc.) and the signer's private key will perform signature calculation on the voltage regulator firmware package to be updated or its hash value to generate a digital signature. This process is essentially to encrypt the data (or its hash value), and only the signer with the corresponding private key can generate a valid signature.

[0098] S112, if the digital signature verification fails, the BMC reports an error and terminates the update process;

[0099] Specifically, on the BMC side, a hash function is used to hash the voltage regulator firmware package to be verified to generate a fixed-length hash value, which is then compared with the decrypted hash value to verify the integrity of the data. The BMC obtains the signature part in the voltage regulator firmware package, decrypts the signature using the signer's public key, and obtains the decrypted hash value. The decrypted hash value is compared with the hash value generated in the above steps. If the two are consistent, it means that the signature is valid and the voltage regulator firmware package has not been tampered with during transmission, thereby ensuring its integrity and authenticity; if they are inconsistent, it means that the signature verification has failed. At this time, the BMC will report an error and terminate the update process to prevent possible malicious or damaged firmware from being installed on the VR chip.

[0100] S113: If the digital signature verification succeeds, continue to execute the update operation of the voltage regulator firmware.

[0101] Specifically, if the digital signature verification is successful, the BMC will continue to execute the update operation of the voltage regulator firmware, including downloading the update package, verifying the update package, burning the firmware to the VR chip, and other steps.

[0102] like Figure 7 As shown, in a more specific embodiment, remote management steps S210-S230 are also included:

[0103] S210, sending an update instruction and a voltage regulator firmware update package to the BMC through a remote management system;

[0104] Specifically, the remote management system first establishes a communication connection with the BMC. The administrator sends an update instruction of the voltage regulator firmware to the BMC through the remote management system, and the instruction includes specific requirements and related information for the update. At the same time, the remote management system also sends an update package of the voltage regulator firmware to the BMC, and the update package includes a new firmware version and related files.

[0105] S220, automatically performing an update operation through the BMC;

[0106] Specifically, after receiving the update instruction and update package, the BMC first performs a check to ensure the integrity and correctness of the update package. After the check passes, the BMC automatically executes the update operation of the voltage regulator firmware according to the update instruction. This may include deleting the old firmware version, installing the new firmware version, and performing necessary configuration and initialization steps. During the update process, the BMC may monitor the update progress and take appropriate measures when encountering problems, such as retrying, rolling back, or notifying the administrator.

[0107] S230: receiving update status and result feedback through the remote management system during or after the update.

[0108] Specifically, during or after the update, the BMC sends update status and result feedback to the administrator through the remote management system. This feedback may include update progress, success or failure prompts, error codes or logs, etc. The administrator can view this information in real time through the remote management system to understand the update status in a timely manner and take corresponding measures.

[0109] Figure 8 is a schematic block diagram of a voltage regulator firmware automatic update device provided by an embodiment of the present application. Figure 8 As shown, corresponding to the above voltage regulator firmware automatic update method, the present application also provides a voltage regulator firmware automatic update device 200.
