[0025] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0026] To more clearly understand the various embodiments provided by the present invention, the technical content related to the present invention is first introduced as follows.

[0027] Baseboard Management Controller (BMC): It is an integrated circuit located on the server motherboard. It is an independent hardware device. BMC is a small operating system independent of the server system. It is a chip integrated on the motherboard. There are also products that are inserted on the motherboard in the form of PCIE, etc. The external manifestation is just a standard RJ45 network port, and it has a firmware system with an independent IP.

[0028] I2C (Inter-Integrated Circuit): It is a serial communication protocol. It is usually used to connect low-speed peripherals, such as sensors, memories, etc. I2C is a two-wire serial communication bus used to connect a microcontroller and its peripheral devices. It is a synchronous half-duplex hardware-level serial communication protocol.

[0029] Independent Watchdog (IWDG): It is a hardware watchdog timer used to monitor the system operation status. If the system does not correctly "feed the dog" within the predetermined time, the IWDG will trigger a system reset. The timeout period of the IWDG can be configured through a prescaler and a reload register. The working principle of the IWDG is implemented through a counter. The counter starts to decrement from a preset reload value. When the counter decrements to 0, the system will be reset. To prevent the system from resetting, it is necessary to reload the reload value before the counter decrements to 0, and this process is called "feeding the dog". The IWDG is a 12-bit down-counter driven by a dedicated low-speed clock and can continue to work even if the main clock fails.

[0030] Microcontroller Unit (MCU): The MCU is an integrated circuit chip that integrates a central processing unit, memory, input / output interfaces, and other peripherals (such as timers / counters, etc.) to form a chip-level microcomputer. The MCU can execute program instructions, process data, implement complex algorithms, and can control various external devices, such as motors, sensors, etc., to achieve automatic control.

[0032] Figure 1 is one of the flow schematic diagrams of the BMC-based board firmware upgrade method provided by the present invention. This method is applied to the BMC intelligent management board processor system in the BMC-based board firmware upgrade system.

[0033] Figure 2 is the structural schematic diagram of the BMC-based board firmware upgrade system provided by the present invention. As Figure 2As shown in the figure, the board firmware upgrade system 200 based on BMC includes a BMC intelligent management board processor system, at least one board, and a front-end operating system. Among them, the BMC intelligent management board processor system includes an RK3568 chip, a power module, SiI9022A (test interface), and IWDG (independent watchdog). It provides a PHY interface 1 to connect to the board through Ethernet and a COM interface 1 to connect to the board through a 485 serial port. The board can be a board of multiple system types, such as a Linux board and an MCU single-chip microcomputer board. The front-end operating system includes a network port peripheral, a PC processor, and a display.

[0034] The board firmware upgrade method provided in this embodiment is implemented through the following steps: First, receive the self-description information of each board reported by each board. The board in the present invention has self-description information, and the self-description information of the board includes the system type of the board, the type of the board, and the software version information running on the board. Among them, the system type of the board is a Linux board or an MCU single-chip microcomputer board, a Linux board, an MCU single-chip microcomputer board, and the type of the board is, for example, a fan board, an upgrade board, and an input / output board. Each board reports the self-description information to the BMC intelligent management board processor system through the 485 serial port via the MODBUS protocol respectively.

[0035] After the BMC intelligent management board processor system receives the self-description information of each board, it sends the self-description information of each board to the front-end operating system, that is, displays the self-description information of each board on the front-end page of the front-end operating system through the front-end operating system.

[0036] Step 102: According to the selected board to be upgraded among the boards, obtain the upgrade firmware corresponding to the board to be upgraded; the board to be upgraded is sent to the BMC intelligent management board processor system by the user after determining the target option in the corresponding front-end page in the front-end operating system, and the target option is determined based on the self-description information of each board; Specifically, displaying the self-description information of each board on the front-end page of the front-end operating system facilitates the front-end page to select the board to be upgraded according to the self-description information of each board.

[0037] After determining the board to be upgraded, the internal program of the BMC intelligent management board uploads the corresponding upgrade firmware according to the board to be upgraded selected on the front-end page such as a web page. Among them, there are certain requirements for packaging the upgrade firmware of each board. It is required that the firmware name corresponds to it, and the firmware is attached with its own MD5 checksum, so that both the Linux board and the single-chip microcomputer board can receive their own required firmware and can also perform verification.

[0038] Step 103: Send a notification message to the board card that needs to be upgraded; the notification message is used to instruct the board card that needs to be upgraded to obtain the corresponding upgrade firmware for the board card that needs to be upgraded from the BMC intelligent management board card processor system in response to the notification message for firmware upgrade.

[0039] Specifically, after the board card that needs to be upgraded uploads the corresponding upgrade firmware, a notification message is sent to the board card that needs to be upgraded through the MODBUS protocol.

[0040] After the board card that needs to be upgraded receives the notification message, it obtains the corresponding upgrade firmware from the BMC intelligent management board card processor system for firmware upgrade. In particular, in the present invention, different acquisition paths are adopted for board cards of different system types, that is, for the upgraded board card BMC intelligent management board card, a dual - processing mechanism is adopted inside, and each managed board card is upgraded through the network cable and the 485 serial port respectively.

[0041] The method provided in this embodiment is applied to the BMC intelligent management board card processor system in the BMC - based board card firmware upgrade system. The BMC - based board card firmware upgrade system includes a BMC intelligent management board card processor system, at least one board card, and a front - end operating system. First, receive the self - description information of each board card reported by each board card, and send the self - description information of each board card to the front - end operating system. The self - description information of the board card includes the system type of the board card, the type of the board card, and the software version information of the board card running; then, according to the selected board card that needs to be upgraded among each board card, obtain the corresponding upgrade firmware for the board card that needs to be upgraded, where the board card that needs to be upgraded is sent to the BMC intelligent management board card processor system by the user after determining based on the target option in the corresponding front - end page in the front - end operating system, and the target option is determined based on the self - description information of each board card; furthermore, send a notification message to the board card that needs to be upgraded, and the notification message is used to instruct the board card that needs to be upgraded to obtain the corresponding upgrade firmware for the board card that needs to be upgraded from the BMC intelligent management board card processor system in response to the notification message for firmware upgrade.

[0042] In the present invention, each board card has self - description information. The self - description information of the board card includes the system type of the board card, the type of the board card, and the software version information of the board card running. After the BMC receives the self - description information of each board card, it selects the board card that needs to be upgraded through the front - end page, and then obtains the corresponding upgrade firmware for the board card that needs to be upgraded and sends a notification message to the board card that needs to be upgraded, instructing the board card that needs to be upgraded to obtain the upgrade firmware from the BMC in response to the notification message for firmware upgrade. The present invention effectively realizes the firmware upgrade of board cards of different system types based on BMC and solves the compatibility problem.

[0043] A method for upgrading the board firmware based on BMC provided by the present invention receives the self-description information of each board reported by each board and sends the self-description information of each board to the front-end operating system, including: Receiving the self-description information of each board reported by each board through the 485 serial port via the MODBUS protocol; Sending the self-description information of each board to the front-end operating system through the PHY interface via the Ethernet driver protocol; the front-end page corresponding to the front-end operating system is a web page, and the self-description information of each board is used for the web page to display the self-description information of each board.

[0044] Specifically, in some embodiments, step 101 can be implemented through the following steps: Receiving the self-description information of each board reported by each board through the 485 serial port via the MODBUS protocol.

[0045] Furthermore, sending the self-description information of each board to the front-end operating system through the PHY interface via the Ethernet driver protocol, the front-end page corresponding to the front-end operating system is a web page, and the self-description information of each board is used for the web page to display the self-description information of each board, that is, displaying the information and types of each board existing in this chassis on the web page.

[0046] The method provided in this embodiment receives the self-description information of each board reported by each board through the 485 serial port via the MODBUS protocol, and then sends the self-description information of each board to the front-end operating system through the PHY interface via the Ethernet driver protocol, for displaying the self-description information of each board through the web page and selecting the board to be upgraded. The present invention effectively realizes the firmware upgrade of boards of different system types based on BMC and solves the compatibility problem.

[0047] A method for upgrading the board firmware based on BMC provided by the present invention obtains the upgrade firmware corresponding to the board to be upgraded according to the selected board to be upgraded among each board, including: Determining the system type corresponding to the board to be upgraded; the system type includes a Linux board or a single-chip microcomputer board; Obtaining the packaged upgrade firmware corresponding to the board to be upgraded according to the system type corresponding to the board to be upgraded; Wherein, the firmware name for packaging the upgrade firmware corresponding to the board to be upgraded is determined based on the system type, board type, and software version information of the board to be upgraded.

[0048] Specifically, in some embodiments, the specific implementation process of obtaining the upgrade firmware corresponding to the board cards to be upgraded according to the selected board cards to be upgraded in each board card in step 102 includes the following steps: First, determine the system type corresponding to the board cards to be upgraded. Among them, the system type includes Linux board cards or single-chip microcomputer board cards. Linux board cards and single-chip microcomputer board cards are two different types of embedded system development boards, and they have significant differences in aspects such as hardware architecture, software environment, and application scenarios: Among them, for Linux board cards: Linux board cards generally refer to development boards running embedded Linux systems. These board cards are usually based on ARM or other high-performance microprocessors (MPUs), and can run Linux or other complex operating systems. Linux board cards usually require external ROM and RAM, have rich hardware resources, support complex peripherals, and run a complete Linux operating system with functions such as file system, process management, and memory management. The development environment of Linux board cards is usually carried out on a host, using a cross-compiler to compile the program into an executable file on the target platform, and then loading it onto the target device through the file system for execution.

[0049] For single-chip microcomputer board cards: Single-chip microcomputer board cards refer to development boards based on microcontrollers (MCUs), such as 8051, AVR, STM32, etc. These board cards usually integrate a core processor, a small amount of ROM, RAM, and some peripheral interfaces. Hardware resources: Generally, single-chip microcomputers integrate flash and ram inside the chip, and the peripherals are relatively simple. Software environment: Single-chip microcomputers usually do not have an operating system, or use a simple real-time operating system (RTOS). Programmers need to manage resources by themselves, including memory, peripherals, etc., and usually directly operate hardware registers for programming. Development environment: Single-chip microcomputer development is usually carried out in an integrated development environment (IDE), and programmers can directly write code, compile, debug, and download the program to the single-chip microcomputer for operation in the IDE.

[0050] The differences between Linux board cards and single-chip microcomputer board cards are as follows: Different in hardware resources and peripherals: Linux board cards usually have richer hardware resources and peripheral support, while single-chip microcomputer board cards are relatively simple. Different in software complexity: Linux board cards run a complete operating system, support multitasking and complex software development, while single-chip microcomputer board cards are usually used for simple control tasks. Different in development environment and tools: The development environment of Linux board cards is more complex, involving cross-compilation and file system management, while the development environment of single-chip microcomputer board cards is relatively simple, and usually uses an IDE for development.

[0051] Further, according to the system type corresponding to the board card to be upgraded, obtain the packaged upgrade firmware corresponding to the board card to be upgraded, that is, upload the corresponding upgrade firmware. Among them, the firmware name for packaging the upgrade firmware corresponding to the board card to be upgraded is determined based on the system type, board card type, and software version information of the board card in operation. In this way, whether it is a Linux board card or a microcontroller board card, it can receive its own required firmware and perform verification.

[0052] The method provided in this embodiment obtains the packaged upgrade firmware corresponding to the board card to be upgraded based on the system type corresponding to the board card to be upgraded. Among them, the firmware name for packaging the upgrade firmware corresponding to the board card to be upgraded is determined based on the system type, board card type, and software version information of the board card in operation, which is convenient for board cards of different system types to each receive their own required upgrade firmware for upgrading, and solves the compatibility problem.

[0053] According to a board card firmware upgrade method based on BMC provided by the present invention, in response to a notification message, obtain the upgrade firmware corresponding to the board card to be upgraded from the BMC intelligent management board card processor system for firmware upgrade, including: In response to the notification message, when it is determined that the system type of the board card to be upgraded is a Linux board card, download the first upgrade firmware corresponding to the board card to be upgraded of the Linux board card type from the BMC intelligent management board card processor system through the File Transfer Protocol (FTP) server; the first upgrade firmware includes first firmware information and a first MD5 verification code; Perform information verification on the first upgrade firmware according to the firmware information in the first upgrade firmware and the self-description information corresponding to the board card to be upgraded of the Linux board card type; When it is determined that the information verification passes, further verify based on the first MD5 verification code and the MD5 verification code received by the board card itself of the Linux board card type to be upgraded; When it is determined that the first MD5 verification code verification is successful, reply to the BMC intelligent management board card processor system with the upgrade success information corresponding to the board card to be upgraded of the Linux board card type.

[0054] Specifically, in some embodiments, the specific implementation process of the board card obtaining the upgrade firmware corresponding to the board card to be upgraded from the BMC intelligent management board card processor system in response to the notification message for firmware upgrade includes the following steps: In the present invention, different upgrade paths correspond to board cards of different system types. The following introduces the upgrade path when the system type of the board card to be upgraded is a Linux board card: The BMC intelligent management board processor system builds an internal File Transfer Protocol (FTP) server. When the system type of the board to be upgraded is a Linux board, the Linux board downloads the corresponding first upgrade firmware for the Linux board from the BMC intelligent management board processor system through the FTP server. Among them, the first upgrade firmware includes first firmware information and a first MD5 verification code. The first firmware information contains self-description information corresponding to the Linux board, which is used to verify whether the firmware corresponds to the information of its own board.

[0055] Further, after obtaining the first upgrade firmware, the firmware information in the first upgrade firmware is matched with the self-description information of the Linux board, and then the information verification of the first upgrade firmware is performed.

[0056] Further, when it is determined that the information verification passes, further verification is performed based on the first MD5 verification code and the MD5 verification code received by the board to be upgraded of the Linux board type. Self-verification is performed according to the MD5 verification code sent by the BMC and the firmware MD5 verification code received by itself.

[0057] Further, when it is determined that the first MD5 verification code is successfully verified, a firmware upgrade success message corresponding to the board to be upgraded of the Linux board type is sent back to the BMC intelligent management board processor system. After that, the BMC intelligent management board processor system restarts the board with successful upgrade.
