[0020] Please refer to Figure 1 , Figure 1 which shows the overall flowchart of a CPLD-based mainboard firmware update management method provided by an embodiment of the present application.

[0021] As Figure 1 shown, the CPLD-based mainboard firmware update management method can at least include the following steps: Step 101: When the first interface switching module detects a lock instruction, switch to the serial port corresponding to the lock instruction and output the signal of the serial port to the protocol parsing module.

[0022] In the embodiment of the present application, the motherboard firmware update management method based on CPLD is applied to a CPLD device, which includes a first interface switching module, a second interface switching module, a protocol parsing module, a switching control module, and a storage control module. Among them, the first interface switching module is used to monitor the input data of multiple serial ports at all times and perform serial port switching according to instructions; the second interface switching module is used to establish a connection between the storage control module and the chip firmware; the protocol parsing module is used to parse the received serial port signal and output it; the switching control module is used to receive the switching instruction from the protocol parsing module and output the corresponding switching switch signal to the second interface switching module; the storage control module is used to execute the update operation of the chip firmware. In the process of motherboard firmware update management based on CPLD, the first interface switching module quickly detects the locking instruction and switches to the corresponding serial port, and then the protocol parsing module accurately parses the switching instruction, control instruction, and firmware information in the serial port signal, so that the switching control module outputs the switching switch signal according to the parsed switching instruction, and the second interface switching module establishes a connection between the storage control module and the chip firmware to execute the update operation of the chip firmware according to the control instruction and firmware information, realizing the reception of switching instructions and control instructions through the serial port, making the firmware update process can flexibly adapt to different update requirements and scenarios, simplifying the firmware update process, and reducing the operation complexity.

[0023] Specifically, in the process of motherboard firmware update management based on CPLD, when the first interface switching module receives the locking instruction, it can switch to the serial port corresponding to the instruction and transmit the signal of the serial port to the protocol parsing module for processing.

[0024] It can be understood that the first interface switching module is a module responsible for managing and switching different interfaces (such as serial ports, network interfaces, etc.). In this solution, it specifically refers to a module that can detect and respond to the locking instruction, which is used to specify the specific serial port to be used. The locking instruction is a specific signal or command used to tell the first interface switching module which serial port is currently needed. This instruction can come from, but is not limited to, user input, upper-layer software logic, or external devices.

[0025] After the interface switching module receives the locking instruction, it can find and switch to the corresponding serial port according to the information specified in the instruction. This process may involve closing the currently used serial port (if any) and opening or activating the specified serial port. Once switched to the specified serial port, the first interface switching module can start receiving the signals on that serial port. These signals can then be transmitted to the protocol parsing module, which is responsible for parsing the data in the signals to extract useful information or perform corresponding operations.

[0026] As an option in the embodiment of the present application, after the first interface switching module detects a locking instruction and switches to the serial port corresponding to the locking instruction, it further includes: When the first interface switching module detects an unlocking instruction, it switches to the initial monitoring state to monitor the data input of at least two serial ports.

[0027] Specifically, after switching to the serial port corresponding to the locking instruction, when the first interface switching module receives an unlocking instruction, it can switch back from the currently active serial port to the initial monitoring state and start monitoring the data input of at least two serial ports simultaneously.

[0028] It can be understood that the first interface switching module is a module responsible for managing and switching different interfaces (especially serial ports). It can detect and respond to instructions from the system or other modules to change the currently active serial port. The unlocking instruction is a specific signal or command used to tell the first interface switching module to stop monitoring the currently active serial port and return to a state where it can monitor multiple serial ports simultaneously. This instruction can come from, but is not limited to, user input, upper-layer software logic, or external devices, indicating that the system no longer needs to focus on the input of a specific serial port.

[0029] After the first interface switching module receives the unlocking instruction, it can stop the currently active serial port communication and then switch to an initial monitoring state, which allows it to monitor the data input of at least two serial ports simultaneously. The initial monitoring state means that the first interface switching module is listening to all connected serial ports and is ready to switch the active serial port according to subsequent instructions or data activities.

[0030] It should be noted that in the initial monitoring state, the interface switching module can simultaneously pay attention to the data input of at least two serial ports. This means that it can receive and cache the data from these serial ports until the system decides which serial port's data needs to be further processed. Monitoring multiple serial ports allows the system to respond more flexibly to data from different sources, improving the system's availability and response speed.

[0031] Step 102: The protocol parsing module parses out the switching instruction, control instruction, and firmware information according to the signals of the serial port.

[0032] Specifically, after obtaining the signals of the serial port, the protocol parsing module is responsible for parsing the signals from the serial port and extracting the key instruction information, including the switching instruction, control instruction, and firmware information.

[0033] It is understandable that the protocol parsing module is a specially designed module for parsing and understanding the data signals received from the serial port. It can parse out the valid information and instructions in the data according to predefined protocols or rules. Serial port signals refer to the data streams transmitted through the serial port, usually including a series of bits or bytes. These signals may represent text data, control commands, or other types of information. The switching instruction is a special command used to switch other modules to another serial port or interface. In some systems, the switching instruction may be used to switch between multiple devices or data sources so that the system can process data from different sources. Control instructions are commands used to control the behavior of devices or systems. These instructions include start, stop, configuration parameter changes, etc. After receiving the control instructions, the system will perform corresponding operations according to the content of the instructions. Firmware information refers to the data related to the device firmware, such as firmware version, update status, etc. Firmware is the software embedded in the device, responsible for the underlying operations and controls of the device. By parsing the firmware information in the serial port signal, the system can understand the firmware status of the device and update or configure it as needed.

[0034] Step 103: The protocol parsing module sends the switching instruction to the switching control module, and sends the control instruction and the firmware information to the storage control module.

[0035] Specifically, after parsing out the key information in the serial port signal, the protocol parsing module can distribute this information to the corresponding modules of the system. Among them, the switching instruction will be sent to the switching control module, while the control instruction and the firmware information will be sent to the storage control module.

[0036] It should be noted that the switching control module is responsible for receiving the switching instruction and performing corresponding switching operations according to the content of the instruction. It involves closing the currently active serial port or interface and opening or activating the specified new serial port or interface; the storage control module is responsible for receiving and processing the control instruction and the firmware information. For the control instruction, it may perform corresponding operations, such as changing the device configuration or starting a specific function. For the firmware information, it is responsible for storing, updating, or verifying the firmware version of the device.

[0037] Step 104: The switching control module outputs a switching switch signal to the second interface switching module according to the switching instruction, so as to establish a connection between the storage control module and the chip firmware through the second interface switching module.

[0038] Specifically, after receiving the switching instruction from the protocol parsing module, the switching control module can generate and output a switching switch signal to the second interface switching module to guide the second interface switching module to establish a connection between the storage control module and the chip firmware.

[0039] It is understandable that the switching control module is responsible for receiving switching instructions and generating corresponding switching switch signals according to these instructions. It communicates with the protocol parsing module, receives the parsed switching instructions, and converts them into specific control signals.

[0040] The switching switch signal is a control signal output by the switching control module, which is used to guide the second interface switching module to perform interface switching. This signal may be an electrical signal, a change in logic level, or other forms of control signals.

[0041] The second interface switching module is responsible for switching interfaces or paths according to the switching switch signal. It is connected to the switching control module, the storage control module, and the chip firmware interface, and is responsible for establishing connections between them.

[0042] The storage control module is responsible for managing and controlling the operations of storage devices, such as reading and writing data, firmware updates, etc. In this solution, it needs to establish a connection with the chip firmware for firmware updates or reading firmware information.

[0043] The chip firmware is software embedded in the hardware device, which is responsible for the underlying operations and control of the device. The storage control module needs to establish a connection with the chip firmware for firmware updates, configuration changes, and other operations.

[0044] Step 105: The storage control module performs an update operation on the chip firmware according to the control instruction and the firmware information.

[0045] Specifically, after receiving the control instruction and the firmware information from the protocol parsing module, the storage control module is responsible for performing the update operation on the chip firmware. This step is a key link in firmware management and device maintenance, ensuring that the device can run the latest firmware version and thus enjoy the latest functions and security fixes.

[0046] It is understandable that the storage control module is a component responsible for managing and controlling the operations of storage devices (such as flash memory, hard disks, etc.). In this solution, it is particularly responsible for handling operations related to chip firmware updates.

[0047] The control instruction is issued by the upper-layer software or the user and is a command used to guide the storage control module to perform specific operations. In the context of firmware updates, the control instruction can but is not limited to include starting the update, verifying the integrity of the firmware, confirming the completion of the update, etc.

[0048] The firmware information is detailed data about the chip firmware, including the firmware version, the size of the update package, the checksum, etc. These information are crucial for ensuring the correctness and integrity of the firmware update.

[0049] Chip firmware is software embedded in hardware devices and is responsible for the underlying operations and control of the devices. Firmware updates are usually used to fix known bugs, add new features, or improve device performance.

[0050] The firmware update operation involves writing a new firmware version to the chip firmware storage area and may include steps such as verifying the integrity of the new firmware, backing up the old firmware version, and restarting the device to apply the new firmware.

[0051] As another option in the embodiments of this application, the CPLD device further includes a data encapsulation module; After the storage control module performs a firmware update operation on the chip firmware according to the control instruction and firmware information, it further includes: The data encapsulation module receives the feedback information and firmware information sent by the storage control module, and encapsulates the feedback information and firmware information to obtain encapsulated data; Send the encapsulated data to the first interface switching module and transmit it to an external device through the first interface switching module for viewing and confirmation by the user or administrator.

[0052] Specifically, during the motherboard firmware update management based on CPLD, the CPLD device may further include a data encapsulation module. After the storage control module performs a firmware update operation on the chip firmware, the data encapsulation module is responsible for receiving the feedback information and firmware information sent by the storage control module, and encapsulating this information into a specific format or data packet, and then transmitting it to an external device through the first interface switching module to ensure that the user or administrator can conveniently view and confirm the results and detailed information of the firmware update.

[0053] It can be understood that the data encapsulation module is a key component in the firmware update process, which is responsible for the reception, encapsulation, and transmission of information. This module can parse the feedback information (such as update status, error code, etc.) and firmware information (such as firmware version, update description, etc.) sent by the storage control module, and integrate this information into a format that is easy to transmit and parse. The encapsulation process involves multiple steps, including information formatting, adding checksum, encryption, etc. The formatting step converts the information into a specific data structure or protocol format so that the external device can correctly parse it. Adding a checksum ensures the integrity of the encapsulated data and can detect whether the data is damaged during transmission. The encryption step ensures the security of the encapsulated data and prevents unauthorized access or tampering.

[0054] As another option in the embodiments of this application, before the data encapsulation module receives the feedback information and firmware information sent by the storage control module, it further includes: When the storage control module detects that the update operation is completed, generate feedback information based on the working status information and data verification information; Send the feedback information and firmware information to the data encapsulation module.

[0055] Specifically, before the data encapsulation module receives the feedback information and firmware information sent by the storage control module, when the storage control module detects that the update operation is completed, it can generate feedback information based on the working status information and data verification information to ensure that the system can accurately understand the status of the firmware update and provide reliable update results for the user.

[0056] It can be understood that the storage control module continuously tracks the progress of the firmware update, including key steps such as writing the new firmware and verifying the integrity of the firmware. During the update process, the storage control module collects and records the working status information, such as the update progress, writing speed, error logs, etc. These information are crucial for diagnosing problems and optimizing the update process. To ensure the accuracy of the firmware update, the storage control module verifies the data after the update is completed. This usually involves calculating the checksum of the data and comparing it with the expected checksum. If the two match, it indicates that the firmware data is complete and not damaged.

[0057] It should be noted that once the storage control module detects that the update operation is completed and the data verification passes, it can generate feedback information based on the collected working status information and data verification information. The feedback information usually includes the status of whether the update is successful, any error codes or logs encountered, and the new version information of the firmware, etc. After generating the feedback information, the storage control module can send it together with the firmware information (such as firmware version, update description, etc.) to the data encapsulation module. The firmware information may have been provided by other modules during the update process, or parsed by the storage control module from the firmware update package.

[0058] As another option of the embodiment of the present application, before the data encapsulation module encapsulates the feedback information and firmware information, it further includes: The data encapsulation module calculates the hash values of the feedback information and firmware information and compares them with the expected hash values provided by the storage control module; When the comparison result is that the hash values match, continue to execute the encapsulation step; When the comparison result is that the hash values do not match, record the error log and send an error notification to the external device to indicate that the information has been tampered with or damaged during the transmission process.

[0059] Specifically, before the data encapsulation module encapsulates the feedback information and firmware information, after receiving the feedback information and firmware information sent by the storage control module, the data encapsulation module can first calculate the hash values of these information. A hash value is a digital digest of a fixed length, which is obtained by performing specific mathematical operations on the original information and has uniqueness and irreversibility. Therefore, the hash value can be used to verify the integrity and authenticity of the information. The calculated hash value will be compared with the expected hash value provided by the storage control module. The expected hash value is calculated by the storage control module based on the feedback information and firmware information during the firmware update process and sent to the data encapsulation module as a reference standard.

[0060] Next, when the calculated hash value matches the expected hash value, it indicates that the feedback information and firmware information have not been tampered with or damaged during the transmission process, and the data encapsulation module will continue to perform the encapsulation steps. The encapsulation steps may include data formatting, encryption, adding checksums, etc. to ensure the integrity and security of the data during subsequent transmission.

[0061] When the calculated hash value does not match the expected hash value, it indicates that the feedback information and firmware information may have been tampered with or damaged during the transmission process. At this time, the data encapsulation module will record an error log, detailing the time, reason, and information involved in the error. At the same time, the data encapsulation module will also send an error notification to an external device, prompting the user or administrator that the information may have been tampered with or damaged during the transmission process and suggesting taking corresponding measures for troubleshooting and repair.

[0062] As another alternative in the embodiment of the present application, after the storage control module performs an update operation on the chip firmware according to the control instruction and the firmware information, it further includes: When the storage control module detects that the difference between the performance parameters of the chip firmware after the update and the preset performance parameters is not within the preset threshold range, it connects to the backup storage area through the second interface switching module and reads the old version firmware from the backup storage area; wherein, the backup storage area is used to store the old version firmware; Write the old version firmware into the chip firmware to restore the normal operation of the system.

[0063] Specifically, after the storage control module performs an update operation on the chip firmware, when the storage control module detects that the difference between the performance parameters of the chip firmware after the update and the preset performance parameters is not within the preset threshold range, it can connect to the backup storage area through the second interface switching module, and then read the old version firmware from the backup storage area, so that the old version firmware can be written into the chip firmware to make the system return to the state before the update, thereby ensuring the normal operation of the system, wherein the backup storage area is used to store the old version firmware.

[0064] It can be understood that the storage control module is responsible for monitoring the performance parameters after the chip firmware is updated. These parameters can include, but are not limited to, key indicators such as read / write speed, power consumption, and stability. The preset performance parameters are the performance standards expected by the system, and the preset threshold range is the acceptable range allowing the performance parameters to deviate from the preset values. When the difference between the actual performance parameters and the preset parameters exceeds this range, the system believes that there may be problems with the new firmware. Once the storage control module detects that the performance parameters exceed the threshold range, a fallback mechanism will be triggered to ensure the stability and reliability of the system and prevent system failures or data losses caused by problems with the new firmware. The second interface switching module is responsible for connecting to the backup storage area when needed. This module may involve the switching of physical interfaces or the selection of logical channels to ensure that the system can smoothly access the data in the backup storage area. The backup storage area is a dedicated area for storing the old version of the firmware. Before the firmware is updated, the system will back up the currently running firmware version to this area so that when a fallback is needed, the system can quickly read the old version of the firmware from the backup storage area. Once connected to the backup storage area, the system will read the old version of the firmware from this area and write it into the chip firmware. This process involves steps such as decompression, verification, and validation of the firmware to ensure the correctness and integrity of the old version of the firmware.

[0065] As another alternative of the embodiment of the present application, the CPLD device further includes a remote management interface; After the storage control module performs an update operation on the chip firmware according to the control instruction and the firmware information, it further includes: The first interface switching module displays real-time data to the administrator through the remote management interface so that the administrator can monitor the firmware update status from a remote location.

[0066] Specifically, in the process of managing the motherboard firmware update based on the CPLD, the CPLD device further includes a remote management interface. After the storage control module performs an update operation on the chip firmware, the first interface switching module can further display real-time data to the administrator through the remote management interface so that the administrator can monitor the status of the firmware update from a remote location, ensuring the smooth progress of the update process and timely response to possible problems. It can be understood that the remote management interface is a dedicated communication channel for transmitting real-time data and management instructions during the firmware update process.
