DETAILED DESCRIPTION

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0013] It should be noted that, in the description of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. The terms "first," "second," etc., in the present invention are used to distinguish similar objects, and are not used to describe a particular order or precedence.

[0014] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0015] The management controller is a critical component in servers, playing a vital role in server operation and management. Common management controllers include the baseboard management controller (BMC), iLO (Integrated Lights-out), iDRAC (Integrated Dell Remote Access Controller), and other management controllers. In related technologies, if the system firmware itself experiences an anomaly or the memory storing the system firmware fails, the management controller will fail to start, making it difficult for users to locate the fault.

[0016] In view of this, in order to solve the technical problem of how to ensure that the management controller can load the system firmware normally and avoid the management controller from being unable to start normally due to system firmware abnormalities or memory failures, the present invention can provide a management controller, which can be equipped with a hardware switching module and two memories using different bus communications in the management controller, so that the memory location of the processor loading firmware can be switched through the hardware switching module, thereby effectively ensuring the normal operation of the management controller.

[0017] For easier understanding, please refer to Figure 1 , Figure 1 This is a structural block diagram of a management controller provided by an embodiment of the present invention. The management controller may include: Processor 1, hardware switching module 2, first memory 3, second memory 4, and register 7. Processor 1 can be connected to hardware switching module 2 and register 7, and connected to first memory 3 via a first bus 5 and to second memory 4 via a second bus 6. First bus 5 and second bus 6 correspond to different bus communication protocols. Both first memory 3 and second memory 4 store system firmware.

[0018] It should be noted that this embodiment does not limit the specific bus communication protocol used by the first bus 5 and the second bus 6, which can be set according to actual application requirements. In one embodiment, the first bus 5 can be an SPI bus (Serial Peripheral Interface) and communicate based on the SPI protocol; the second bus 6 can be a MIPIM-PHY bus (Mobile Industry Processor Interface). This embodiment also does not limit the specific types of the first memory 3 and the second memory 4, which can be set according to actual application requirements. In one embodiment, the first memory 3 can be SPI non-volatile flash memory (SPI Nor Flash), and the second memory 4 can be UFS memory (Universal Flash Storage).

[0019] In addition, this embodiment does not limit the specific form of the hardware switching module 2, which can be set according to actual application requirements. For example, the hardware switching module 2 can be a hardware switch or a hardware circuit that can generate a level signal.

[0020] In addition, this embodiment does not limit the specific form of the register 7 , as long as it can store the startup configuration of the management controller, for example, it can be an OTP (One Time Programmable) register.

[0021] The following are the specific uses of the hardware switching module 2, processor 1, and registers: Register 7 is used to save the startup configuration.

[0022] The hardware switching module 2 is used to receive an input signal and generate a selection signal according to the input signal.

[0023] Processor 1 is used to adjust the startup configuration in the register according to the selection signal when powered on; determine the target memory for loading the system firmware in the first memory and the second memory according to the adjusted startup configuration, and load the system firmware from the target memory.

[0024] In this embodiment, the hardware switching module 2 is used to receive an input signal and generate a selection signal based on the input signal. The input signal is a signal input by the user to the hardware switching module 2, and the signal input can be achieved by operating the structure in the hardware switching module 2. For example, when the hardware switching module 2 is a hardware switch, the user can achieve signal input by adjusting the on and off of the switch. When the hardware switching module 2 is a circuit, the user can achieve signal input by inputting a level signal into the circuit. The selection signal can have two signal values, corresponding to the first memory 3 and the second memory 4 respectively. Register 7 is used to store the startup configuration, which is used to start the management controller and at least includes a startup position value, indicating which memory to load the system firmware from. Furthermore, when the processor 1 is powered on and started, it can first obtain the selection signal, and then adjust the startup configuration in the register according to the selection signal, and then determine the target memory for loading the firmware in the first memory 3 and the second memory 4 according to the adjusted startup configuration, and load the system firmware from the target memory. For example, when the selection signal is a first signal value, the processor 1 can load the system firmware in the first memory 3 according to the adjusted startup configuration; when the selection signal is a second signal value, the processor 1 can load the system firmware in the second memory 4 according to the adjusted startup configuration.

[0025] It is worth noting that since the first memory 3 can be connected to the processor 1 through the first bus 5, and the second memory 4 can be connected to the processor 1 through the second bus 6, the first bus 5 and the second bus 6 are different communication links and are based on different bus communication protocols. Therefore, the processor 1 can load the system firmware from different memories through different buses, and the firmware loading position can be flexibly adjusted through the hardware switching module 2, thereby improving the reliability of system firmware loading.

[0026] For example, in one embodiment, the first memory 3 is a main memory that stores the main system firmware; the second memory 4 is a backup memory that stores the backup system firmware. When the main system firmware is damaged, the first memory 3 fails, or the first bus 5 fails, the user can use the hardware switching module 2 to send a selection signal to switch to the second memory 4, and the processor 1 can load the backup system firmware from the second memory 4 via the second bus 6 based on the selection signal. In this way, when the main system firmware is damaged, the first memory 3 fails, or the first bus 5 fails, the processor 1 can also load the backup system firmware from other memories via other buses. This can avoid the defect that the management controller cannot load the system firmware due to damage to the main system firmware, failure of the memory storing the main system firmware, or failure of the bus, and can effectively ensure the normal startup of the management controller.

[0027] In another embodiment, the hardware switching module 2 is a hardware switch. In this case, the processor 1 can also be used to: When the hardware switch is in the first state, adjusting the startup position value in the startup configuration to a first value; When the hardware switch is in the second state, adjusting the start position value to a second value; When the startup position value is the first value, the system firmware is loaded from the first memory 3; When the startup position value is the second value, the system firmware is loaded from the second memory 4 .

[0028] In this embodiment, the hardware switching module 2 can be in the form of a hardware switch. In this case, the user can adjust the state of the hardware switch by turning the switch on / off, thereby guiding the processor to adjust the startup position value in the startup configuration, and then guiding the processor to load the system firmware from different memories.

[0029] It should be noted that this embodiment does not limit the specific first state and second state, and can be set according to actual application requirements. For example, the first state can be the switch-on state, and the second state can be the switch-off state; for another example, the first state can be the switch-off state, and the second state can be the switch-on state.

[0030] Based on the above embodiment, the management controller startup method provided by the present invention is introduced below. Figure 2 , Figure 2 This is a flow chart of a method for starting a management controller provided by an embodiment of the present invention. The method is applied to the above-mentioned management controller. The method may include: S201 : When powering on, obtaining a selection signal generated by a hardware switching module.

[0031] In this step, when the processor in the management controller is powered on and started, it first needs to obtain the selection signal generated by the hardware switching module to determine from which memory location to load the system firmware according to the selection signal.

[0032] It should be noted that this embodiment does not limit the specific form of the selection signal, which is related to the specific form of the hardware switching module. For example, when the hardware switching module is a hardware switch, the selection signal can be a switch state; when the hardware switching module is a circuit, the selection signal can also be a level signal.

[0033] S202: Adjust the startup configuration in the register according to the selection signal.

[0034] In this step, the processor needs to adjust the startup configuration in the register according to the above selection signal, so as to enter the subsequent system firmware loading process according to the adjusted startup configuration. Among them, the startup configuration at least includes a startup location value, which is used to indicate which memory to load the system firmware from. The following describes the process of the processor adjusting the startup configuration in the form of a specific hardware switching module: Based on this, the hardware switching module is a hardware switch; adjusting the startup configuration in the register according to the selection signal may include: Step 11: When the hardware switch is in the first state, adjusting the startup position value in the startup configuration to a first value; Step 12: When the hardware switch is in the second state, the start position value is adjusted to a second value.

[0035] In steps 11-12, when the startup position value is the first value, it indicates that the system firmware needs to be loaded from the first memory. When the startup position value is the second value, it indicates that the system firmware needs to be loaded from the second memory. This embodiment does not limit the specific numerical values of the first value and the second value. For example, the first value can be 0 and the second value can be 1. In addition, when it is determined that the hardware switch is in the first state, the register value is adjusted to the first value; when it is determined that the hardware switch is in the second state, the register value is adjusted to the second value. This embodiment also does not limit the specific first state and second state. For example, the first state can be the switch-on state, and the second state can be the switch-off state; for another example, the first state can be the switch-off state, and the second state can be the switch-on state.

[0036] S203 : Determine a target memory for loading the system firmware in the first memory and the second memory according to the adjusted startup configuration, and load the system firmware from the target memory.

[0037] In this step, the management controller's processor can determine the target memory for loading the system firmware from the first memory and the second memory based on the adjusted startup configuration, and then load the system firmware from the target memory. This allows users to flexibly switch the location where the management controller loads the system firmware through the hardware switching module. If a single memory or system firmware fails, the management controller can load the system firmware from another memory location to ensure normal startup of the management controller.

[0038] The following describes the process by which the processor determines where to load the system firmware: Based on this, determining a target memory for loading the system firmware in the first memory and the second memory according to the adjusted startup configuration, and loading the system firmware from the target memory may include: Step 21: When the startup position value is the first value, loading the system firmware from the first memory; Step 22: When the startup position value is the second value, the system firmware is loaded from the second memory.

[0039] Based on the above embodiment, a hardware switching module, a first memory, a second memory, and a register can be set in the management controller of the present invention. The processor in the management controller is connected to the hardware switching module and the register, and is connected to the first memory through a first bus and to the second memory through a second bus. The first bus and the second bus correspond to different bus communication protocols. Among them, the hardware switching module can receive an input signal and generate a selection signal based on the input signal, and the processor can adjust the startup configuration in the register according to the selection signal when powered on, and determine the target memory for loading the firmware in the first memory and the second memory according to the adjusted startup configuration, and load the system firmware from the target memory. In this way, the present invention can switch the location where the processor loads the firmware through the hardware switching module, thereby effectively ensuring the normal startup of the management controller.

[0040] Based on the above embodiment, as described above, in this embodiment, the first memory can be regarded as the main memory and store the main system firmware, while the second memory can be regarded as the backup memory and store the backup system firmware. Furthermore, the management controller is generally booted based on the first memory; when the first memory or the main system firmware fails, the user can switch the management controller to load the backup system firmware from the second memory through the hardware switching module. The following first introduces the method for the management controller to load the system firmware from the second memory. In one embodiment, the second memory can include a boot partition and a normal partition; loading the system firmware from the second memory can include: S401: Load a boot loader from a boot partition.

[0041] S402: Load the operating system kernel from the common partition using the boot loader.

[0042] In this embodiment, the second memory can be divided into a boot partition and a normal partition based on the boot requirements of the management controller. The boot partition is used to store a boot loader (such as U-boot), while the normal partition is used to store operating system content (such as the Linux kernel). Therefore, when loading system firmware, the management controller must first load the boot loader from the boot partition, and then use this boot loader to load the operating system kernel from the normal partition.

[0043] For more information about the management controller startup process, please refer to Figure 3 , Figure 3This is a flowchart of a management controller startup process provided by an embodiment of the present invention. This process may include: 1. Hardware reset; 2. Power and peripheral initialization; 3. Boot ROM execution; 4. Boot program loading; 5. Boot loader initialization; 6. Kernel loading; 7. Kernel initialization; 8. System service startup. The operation of reading the selection signal must be performed before the "Boot ROM execution" step.

[0044] Furthermore, after starting up through the second memory, the management controller may detect the first memory, the first bus, and the system firmware in the first memory.

[0045] Based on this, after loading the system firmware from the second memory, the following steps may also be included: Step 31: After the system firmware in the second memory is loaded, the first bus is tested.

[0046] Step 32: When it is determined that the first bus fails the test, the fault of the first bus is recorded in a log.

[0047] Step 33: When it is determined that the first bus passes the test, the system firmware in the first memory is tested.

[0048] Step 34: When it is determined that the system firmware is damaged, repair the system firmware in the first memory.

[0049] In this embodiment, the first bus may be first tested to determine whether the management controller is unable to load the system firmware from the first memory due to hardware reasons. This embodiment does not limit the detection method of the first bus, and reference may be made to related technologies. If it is determined that the first bus has failed, a log may be recorded to facilitate troubleshooting by the user. If it is determined that the first bus has not failed, the system firmware in the first memory may continue to be tested to determine whether the inability to start is due to firmware damage. This embodiment does not limit how to test the system firmware, such as testing the integrity of the system firmware. When it is determined that the system firmware in the first memory is damaged, the system firmware may be repaired. Specifically, since the management controller can start normally based on the system firmware in the second memory, this embodiment can use the system firmware in the second memory to repair the system firmware in the first memory, thereby improving the convenience of repairing the system firmware.

[0050] Based on this, repairing the system firmware in the first memory may include: Step 41: Repair the system firmware in the first memory using the system firmware in the second memory.

[0051] The following describes in detail how to set the boot partition, common partition, and system firmware in the second memory. Based on this, after loading the system firmware from the first memory, the following steps may also be included: Step 51: After the system firmware in the first memory is loaded, a boot partition and a common partition are set in the second memory.

[0052] Step 52: Write the boot loader to the boot partition and write the operating system kernel to the normal partition.

[0053] In steps 51 and 52, if the management controller can normally boot from the first memory, this embodiment may set up a boot partition and a normal partition in the second memory. For example, a 16GB LUN0 (Logical Unit Number) in the first memory may be allocated as a normal partition, and a 4MB LUN1 may be allocated as a boot partition. Furthermore, to improve boot partition reliability, this embodiment may set up two boot partitions in the first memory: LUN1 (primary boot partition) and LUN2 (backup boot partition). This allows the system kernel to boot from the other boot partition if one boot partition becomes corrupted. It should be noted that this embodiment does not limit how to switch between the primary and backup boot partitions. For example, the user can manually switch between LUN1 and LUN2. For another example, when loading a system image from the second memory, the management controller may prioritize loading the boot loader from the primary boot partition and may use a hardware timer to record the boot duration. If the boot duration exceeds a preset threshold, the management controller triggers a restart and switches to loading the boot loader from the backup boot partition.

[0054] Based on the above embodiment, the management controller startup method is fully described below based on a specific example. In one embodiment, the management controller is a BMC, the first memory is SPI nor Flash, and the second memory is UFS memory. This method may include the following process: 1. Partition the UFS storage in advance and select which LUN to create as a normal LUN or boot LUN.

[0055] Create a 16 GB LUN0 as the user partition, and create 4 MB LUN1 and LUN2 as the boot partition.

[0056] 2. Initialize and configure the UFS storage in the BMC kernel driver.

[0057] 3. Burn the firmware to the UFS storage when the BMC is operating normally.

[0058] - Download the boot loader image "image u-boot" to LUN 1 and LUN 2 separately.

[0059] - Download the kernel image to LUN 0.

[0060] This step requires extracting the UFS image and manually calculating the image sectors. Users can use wic.gz-image to update the user LUN in the next step.

[0061] 4. There is a hardware switch that determines whether to boot from SPI nor flash or UFS. A specific partition stores the boot image. Enables booting uboot from UFS.

[0062] 5. Restart BMC and the image will automatically boot from UFS.

[0063] 6. After the image is started, collect logs and troubleshoot the cause of the problem.

[0064] 7. If it is determined that there is no hardware abnormality and it is just the image problem, you can re-flash the image in SPI nor flash.

[0065] 8. If the problem is caused by an SPI bus abnormality, you can record the abnormality in the log to ensure normal operation of the current business. When conditions permit, repair the equipment to avoid affecting business operations.

[0066] 9. After the machine is in normal state, press the boot button again to boot from SPI nor flash and record the log.

[0067] This restores normal execution of the BMC.

[0068] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
