[0083] The following will be combined with the accompanying drawings of some embodiments of the present application to clearly describe the technical solutions in some embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on some embodiments of the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0084] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0085] The following describes in detail the firmware burning method provided by some embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0086] 1 , which shows a flowchart of a firmware burning method provided by some embodiments of the present application, the firmware burning method can be run on a terminal device such as a computer or a burner. The method may specifically include the following steps:

[0087] Step 101, switch the first line conversion switch of the mainboard to connect the communication transmission interface of the mainboard and the baseboard management controller memory of the mainboard; wherein the first line conversion switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory to connect to the communication transmission interface.

[0088] In some embodiments of the present application, a baseboard management controller (BMC) may be equipped with a BMC memory component, which can store programming files or firmware files, enabling the BMC to implement the functions specified by the programming files or firmware files. The BMC can communicate with external devices via a communication transmission interface. For example, it can transmit log files to an external device or respond to instructions from the external device to operate a server device connected to the BMC. Typically, programming files or firmware files are transferred to the BMC memory component by burning them into the BMC memory component to function. Burning involves transmitting target data in the form of programming signals to a programmable device using specialized software and hardware. These programming signals can change the electronic state within the programmable device, thereby writing or modifying specific data. During the burning process, programming firmware or software tools typically interact with the target device. The programming firmware or software tool converts the target data into specific programming signals and transmits them to the target device via a communication interface. Upon receiving the programming signals, the target device writes the data into its internal storage unit according to the instructions in the signals, thereby updating or modifying the data. Different burning technologies and programming interfaces have different operating principles. In some embodiments of the present application, the communication transmission interface can be an RS232 DB9 female interface with pins 1 to 9, and the programming interface can be a serial peripheral interface (SPI) with five transmission lines. The five transmission lines of the serial peripheral interface can be soldered to pins 1 to 5 of the DB9 female interface. The correspondence between RS232 pins and serial peripheral interface transmission lines is shown in the following table:

[0089] Table 1 RS232 and SPI pin correspondence

[0090] In some embodiments of the present application, in order to prevent confusion and errors in the original communication function of the RS232 interface and the burning function of the serial peripheral interface, an SPI bus and a first line conversion switch can be added between the RS232 interface as the communication transmission interface and the baseboard management controller memory, wherein the first line conversion switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory to connect to the communication transmission interface. When the baseboard management controller memory is connected to the baseboard management controller, the baseboard management controller can access the firmware file or programming file in the baseboard management controller memory to run various functions of the baseboard management controller; when the baseboard management controller memory is connected to the communication transmission interface, the communication line between the baseboard management controller and the baseboard management controller memory is cut off, and the firmware file can be burned into the baseboard management controller memory from the communication transmission interface through the SPI bus.

[0091] In some embodiments of the present application, the first terminal can switch the first line switch to connect the communication transmission interface and the baseboard management controller memory. When the first line switch is switched to connect the communication transmission interface and the baseboard management controller memory, the connection between the baseboard management controller and the baseboard management controller memory can also be disconnected. In addition, the communication transmission interface can be other integrated interfaces besides RS232, such as RS485 type interfaces, etc., which are not limited in the embodiments of the present application.

[0092] Step 102: Burn the firmware file into the memory of the baseboard management controller via the communication transmission interface and the first line switch.

[0093] In some embodiments of the present application, after switching the first line conversion switch so that the baseboard management controller memory and the communication transmission interface are in a connected state, the firmware file for burning can be burned into the baseboard management controller memory through the communication transmission interface, the first line conversion switch and the corresponding transmission line through a burning tool.

[0094] Step 103 : Switching the first line switch to connect the baseboard management controller and the baseboard management controller memory, so that the baseboard management controller calls the firmware file in the baseboard management controller memory.

[0095] In some embodiments of the present application, according to the embodiment of step 101, after programming is completed, the baseboard management controller and the baseboard management controller memory may be in a disconnected state. At this time, the first line transfer switch may be switched to connect the baseboard management controller and the baseboard management controller memory. While switching the first line transfer switch to connect the baseboard management controller and the baseboard management controller memory, the connection between the baseboard management controller memory and the communication transmission interface may be disconnected. After restoring the connection between the baseboard management controller memory and the baseboard management controller, the baseboard management controller may call the firmware file in the baseboard management controller memory, thereby realizing various functions of the baseboard management controller.

[0096] In some embodiments of the present application, the communication transmission interface of the mainboard and the baseboard management controller memory of the mainboard are connected by switching the first line conversion switch of the mainboard; wherein, the first line conversion switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory to connect to the communication transmission interface, and the firmware file is burned into the baseboard management controller memory through the communication transmission interface and the first line conversion switch. The first line conversion switch is switched to connect the baseboard management controller and the baseboard management controller memory, so that the baseboard management controller calls the firmware file in the baseboard management controller memory. The baseboard management controller memory can be burned directly through the communication transmission interface of the baseboard management controller, avoiding the disassembly of the baseboard management controller memory, and reducing the time cost and labor cost of repairing the baseboard management controller memory to a certain extent.

[0097] 2 is a flowchart of another firmware burning method provided by some embodiments of the present application. The method may specifically include the following steps:

[0098] Step 201: Switch the first line switch of the mainboard to connect the communication transmission interface of the mainboard and the baseboard management controller memory of the mainboard; wherein the first line switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory to connect to the communication transmission interface.

[0099] In some embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 101 and will not be repeated here.

[0100] In some embodiments, step 201 may include the following sub-steps:

[0101] Sub-step 2011, switching the second line transfer switch of the mainboard to connect the communication transmission interface and the first line transfer switch; wherein the second line transfer switch is used to switch the communication transmission interface to connect to the baseboard management controller, or the communication transmission interface to connect to the first line transfer switch.

[0102] In some embodiments of the present application, there may be a second line transfer switch on the transmission line between the first line transfer switch and the communication transmission interface, and the second line transfer switch can be used to switch the communication transmission interface to connect to the baseboard management controller, or the communication transmission interface to connect to the first line transfer switch, that is, a second line transfer switch can be set on the transmission line between the communication transmission interface and the baseboard management controller, and a transmission line can be established between the first line transfer switch and the second line transfer switch, so that the baseboard management controller memory can be connected to the communication transmission interface through the first line transfer switch and the second line transfer switch. During normal use of the baseboard management controller, the second line transfer switch can connect the communication transmission interface and the baseboard management controller so that the baseboard management controller can communicate with external devices. In some embodiments of the present application, the second line transfer switch can be switched so that the communication transmission interface and the first line transfer switch can be connected and the connection between the communication transmission interface and the baseboard management controller can be disconnected.

[0103] In sub-step 2012, the first circuit transfer switch is switched to connect the BMC memory to the second circuit transfer switch. The first circuit transfer switch is used to switch the BMC memory to connect to the BMC, or the BMC memory to connect to the second circuit transfer switch.

[0104] In some embodiments of the present application, the first circuit transfer switch is used to switch the connection between the baseboard management controller memory and the baseboard management controller, or the connection between the baseboard management controller memory and the second circuit transfer switch. In some embodiments of the present application, the first circuit transfer switch can be switched to connect the baseboard management controller memory and the second circuit transfer switch and disconnect the baseboard management controller and the baseboard management controller memory.

[0105] In some embodiments of the present application, after switching the second line conversion switch in sub-step 2011 and switching the first line conversion switch in sub-step 2012, the communication transmission interface and the baseboard management controller memory can be connected, so that the baseboard management controller memory can communicate directly with the external device.

[0106] For example, as shown in Figure 3, Figure 3 is a schematic diagram of the component structure of a firmware burning method provided by some embodiments of the present application. In Figure 3, the solid line can be a signal transmission line, and the dotted line can be a power supply line. The terminal device can be directly connected to the communication transmission interface, and the first line conversion switch and the second line conversion switch can be controlled through the communication transmission interface. When the second line conversion switch connects the communication transmission interface and the baseboard management controller, or the first line conversion switch connects the baseboard management controller memory and the baseboard management controller, the baseboard management controller memory cannot be directly connected to the communication transmission interface, nor can it communicate directly with the terminal device through the communication transmission interface. Only when the second line conversion switch connects the communication transmission interface and the first line conversion switch, and the first line conversion switch connects the baseboard management controller memory and the second line conversion switch, can the baseboard management controller communicate directly with the terminal device through the communication transmission interface.

[0107] In some embodiments of the present application, the second line conversion switch of the mainboard is switched to connect the communication transmission interface and the first line conversion switch; wherein, the second line conversion switch is used to switch the communication transmission interface to connect to the baseboard management controller, or the communication transmission interface is connected to the first line conversion switch, and the first line conversion switch is switched to connect the baseboard management controller memory and the second line conversion switch; wherein, the first line conversion switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory is connected to the second line conversion switch, so that the baseboard management controller memory can be connected to the communication transmission interface through the first line conversion switch and the second line conversion switch, and the connection between the baseboard management controller memory and the communication transmission interface and the baseboard management controller is disconnected, thereby avoiding logical confusion and errors that may occur during the burning process, and improving the reliability and security of the firmware burning method.

[0108] Step 202 , turning off a first switch corresponding to a first power source; wherein the first power source and the first switch are located on a mainboard, and the first power source is used to supply power to a baseboard management controller and a baseboard management controller memory through the first switch.

[0109] In some embodiments of the present application, a first switch can connect a first power supply, a baseboard management controller, and a baseboard management controller memory. When the first switch is connected, the first power supply can supply power to the baseboard management controller and the baseboard management controller memory. The first power supply can be a DC regulated power supply, and the voltage value can be adjusted according to the rated voltage of the baseboard management controller. When the baseboard management controller memory is connected to the communication transmission interface, the first switch can be turned off to stop the first power supply from supplying power to the baseboard management controller memory and the baseboard management controller.

[0110] Step 203 , turning on the second switch; wherein the second switch is used to supply power to the baseboard management controller memory from an external power source via the communication transmission interface.

[0111] In some embodiments of the present application, a terminal device connected to the communication transmission interface can be equipped with an external power supply, which can supply power to the baseboard management controller memory via a second switch. The second switch can be turned on to allow the external power supply on the terminal device to supply power to the baseboard management controller memory via the communication transmission interface. After power is supplied to the baseboard management controller memory, the terminal device can recognize the baseboard management controller memory.

[0112] Continuing with the above example, in FIG3 , the terminal device may control the first switch to be disconnected, and then control the second switch to be connected, so that the terminal device can supply power to the baseboard management controller memory.

[0113] In some embodiments of the present application, by turning off the first switch corresponding to the first power supply, wherein the first power supply is used to supply power to the baseboard management controller and the baseboard management controller memory through the first switch, and turning on the second switch, wherein the second switch is used for the external power supply to supply power to the baseboard management controller memory through the communication transmission interface, the power supply of the system can be replaced before the firmware file is burned, thereby avoiding the power supply hidden dangers of the internal power supply of the system and improving the availability and stability of the firmware burning method.

[0114] Step 204 : When the first circuit transfer switch is connected to the BMC memory and the second circuit transfer switch, a first indication signal is sent to the BMC; wherein the first indication signal is used to light up a corresponding red indicator light of the BMC.

[0115] In some embodiments of the present application, a red indicator light may be provided on the baseboard management controller. When the first line transfer switch is connected to the baseboard management controller memory and the second line transfer switch, a first indication signal may be sent to the baseboard management controller to light up the red indicator light on the baseboard management controller.

[0116] In some embodiments, step 204 may include the following sub-steps:

[0117] Sub-step 2041: Acquire the connectivity status of the second line transfer switch.

[0118] In some embodiments of the present application, when the first line transfer switch is connected to the baseboard management controller memory and the second line transfer switch, the connection status of the second line transfer switch can be obtained to determine whether the second line transfer switch is in a state of connecting to the communication transmission interface and the baseboard management controller or in a state of connecting to the communication transmission interface and the first line transfer switch.

[0119] Sub-step 2042 : When the connection state indicates that the second line transfer switch is connected to the communication transmission interface and the first line transfer switch, a first indication signal is sent to the baseboard management controller.

[0120] In some embodiments of the present application, when the second line transfer switch is in a state of connecting the communication transmission interface and the first line transfer switch, a first indication signal may be sent to the baseboard management controller, thereby lighting up a red indicator light.

[0121] In some embodiments of the present application, by obtaining the connectivity status of the second line conversion switch, and when the connectivity status indicates that the second line conversion switch is connected to the communication transmission interface and the first line conversion switch, a first indication signal is sent to the baseboard management controller. When the baseboard management controller memory is directly connected to the communication transmission interface through the first line conversion switch and the second line conversion switch, the corresponding indicator light can be lit, thereby further improving the practicality of the firmware burning method.

[0122] In some embodiments of the present application, a first indication signal is sent to the baseboard management controller when the first line conversion switch is connected to the baseboard management controller memory and the second line conversion switch, wherein the first indication signal is used to light up a red indicator light corresponding to the baseboard management controller. The corresponding indicator light can be lit when the baseboard management controller is directly connected to the communication transmission interface, thereby improving the practicality of the firmware burning method.

[0123] Step 205 : Burn the firmware file into the memory of the baseboard management controller via the communication transmission interface and the first line switch.

[0124] In some embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 102 and will not be repeated here.

[0125] In some embodiments, step 205 may include the following sub-steps:

[0126] Sub-step 2051: displaying first switching information of the first line transfer switch; wherein the first switching information is used to prompt the user to connect the firmware file burner to the communication transmission interface.

[0127] In some embodiments of the present application, when the first line transfer switch is switched to a state connecting the baseboard management controller memory and the communication transmission interface, first switching information of the first line transfer switch can be generated and displayed to show the user the connection state after the first line transfer switch is switched and prompt the user to connect the burner to the communication transmission interface.

[0128] Sub-step 2052: When the burner is connected to the communication transmission interface, the firmware file is burned into the memory of the baseboard management controller through the communication transmission interface and the first line conversion switch.

[0129] In some embodiments of the present application, after the user connects the burner to the communication transmission interface, the user can use the burner to burn the firmware file into the baseboard management controller memory through the communication transmission interface and the first line conversion switch.

[0130] In some embodiments of the present application, the first switching information of the first line transfer switch is displayed; wherein, the first switching information is used to prompt the user to connect the burner of the firmware file to the communication transmission interface. When the burner is connected to the communication transmission interface, the firmware file is burned into the baseboard management controller memory through the communication transmission interface and the first line transfer switch, and the user can be prompted to connect the burner for burning, thereby improving the usability of the firmware burning method.

[0131] Sub-step 2053: convert the format of the firmware file to obtain a burning file corresponding to the firmware file.

[0132] In some embodiments of the present application, the firmware file may be a program file formed based on a certain programming language, used to drive a baseboard management controller, or to upgrade the driver of the baseboard management controller. Typically, the code in such a firmware file cannot be directly recognized by a machine and needs to undergo format conversion to be converted into a burn file that can be directly recognized by the machine. In some embodiments of the present application, if the format of the firmware file does not match the format of a burn file that can be recognized by the machine, the firmware file may be format converted to obtain a burn file that corresponds to the firmware file and can be directly recognized by the machine.

[0133] For example, if the firmware file format is ".c", you can first convert the ".c" format file into a program file format that can be directly recognized and called by the hardware device, such as a ".hex" format file. The file obtained after the format conversion is the burning file.

[0134] Sub-step 2054 , burning the burning file into the memory of the baseboard management controller via the communication transmission interface and the first line conversion switch.

[0135] In some embodiments of the present application, after the firmware file completes format conversion and obtains the burning file, the burning file can be burned into the baseboard management controller memory through the communication transmission interface and the first line conversion switch through a terminal device or burner connected to the communication transmission interface.

[0136] In some embodiments of the present application, by converting the format of the firmware file to obtain a burning file corresponding to the firmware file, and burning the burning file into the baseboard management controller memory through the communication transmission interface and the first line conversion switch, the firmware file can be converted into a burning file that can be directly recognized by the hardware device, thereby improving the availability of the firmware file.

[0137] Step 206 : Switch the first line switch to connect the baseboard management controller and the baseboard management controller memory, so that the baseboard management controller calls the firmware file in the baseboard management controller memory.

[0138] In some embodiments of the present application, the implementation content of this step can refer to the embodiment content of step 103 and will not be repeated here.

[0139] In some embodiments, step 206 may include the following sub-steps:

[0140] Sub-step 2061: Switch the second line transfer switch to connect the communication transmission interface and the baseboard management controller; wherein the second line transfer switch is used to switch the communication transmission interface to connect to the baseboard management controller, or the communication transmission interface to connect to the first line transfer switch.

[0141] In some embodiments of the present application, the connection relationship of the second circuit transfer switch can be the same as the connection relationship of the second circuit transfer switch in step 2011. The connection relationship of the second circuit transfer switch can refer to the embodiment of step 2011. After the burning is completed, the second circuit transfer switch can be switched to reconnect the communication transmission interface and the baseboard management controller, thereby restoring communication between the baseboard management controller and the external device.

[0142] In sub-step 2062, the first circuit transfer switch is switched to connect the BMC memory and the BMC; wherein the first circuit transfer switch is used to switch the BMC memory to connect to the BMC, or the BMC memory to connect to the second circuit transfer switch.

[0143] In some embodiments of the present application, the connection relationship of the first circuit transfer switch can be the same as the connection relationship of the first circuit transfer switch in step 2012. For related details, refer to the embodiment of step 2012. After the second circuit transfer switch is switched, the first circuit transfer switch can be switched to connect the baseboard management controller memory and the baseboard management controller, thereby restoring communication between the baseboard management controller and the baseboard management controller memory.

[0144] For example, in the hardware structure shown in FIG3 , the second line switch can be switched to connect the communication transmission interface and the baseboard management controller, and the first line transfer switch can be switched to connect the baseboard management controller and the baseboard management controller memory. In this way, the second line transfer switch and the first line transfer switch are in a disconnected state, and the terminal device can directly access the baseboard management controller through the communication transmission interface, but cannot directly access the baseboard management controller memory through the communication transmission interface.

[0145] In some embodiments of the present application, the second line conversion switch is switched to connect the communication transmission interface and the baseboard management controller, wherein the second line conversion switch is used to switch the communication transmission interface to connect to the baseboard management controller, or the communication transmission interface is connected to the first line conversion switch, and the first line conversion switch is switched to connect the baseboard management controller memory and the baseboard management controller, wherein the first line conversion switch is used to switch the baseboard management controller memory to connect to the baseboard management controller, or the baseboard management controller memory is connected to the second line conversion switch. After the burning is completed, the second line conversion switch and the first line conversion switch can be switched, so that the normal communication of the baseboard management controller can be restored, thereby improving the practicality of the firmware burning method.

[0146] Step 207 : When the baseboard management controller and the baseboard management controller memory are connected, send a second indication signal to the baseboard management controller; wherein the second indication signal is used to turn off a red indicator light corresponding to the baseboard management controller.

[0147] In some embodiments of the present application, when the first line transfer switch connects the baseboard management controller and the baseboard management controller memory, a second indication signal may be sent to the baseboard management controller, wherein the second indication signal may be used to turn off a corresponding red indicator light of the baseboard management controller.

[0148] In some embodiments of the present application, by sending a second indication signal to the baseboard management controller when the baseboard management controller and the baseboard management controller memory are connected, wherein the second indication signal is used to turn off the red indicator light corresponding to the baseboard management controller, the connectivity status of the first line switching switch can be confirmed by the red indicator light being turned off, thereby improving the practicality of the firmware burning method.

[0149] In some embodiments of the present application, another firmware burning method may be provided. First, a computer may be connected to a communication transmission interface, and then a burning tool may be run on the computer. The burning tool may identify each piece of hardware connected to the computer and may control each piece of hardware to perform various actions. The burning tool may control the second line transfer switch to connect the communication transmission interface to the first line transfer switch, and may control the first line transfer switch to connect the baseboard management controller memory to the second line transfer switch. The burning tool may then identify the baseboard management controller memory, including the identifier and memory size corresponding to the memory. The burning tool may then erase the existing data in the baseboard management controller memory and perform formatting. After formatting, the firmware file is burned into the baseboard management controller memory, completing the burning. After successful burning, the burning tool may control the first and second line transfer switches to return to their initial states, thereby disconnecting the baseboard management controller memory. In this way, the baseboard management controller memory can be burned without disassembling the baseboard management controller memory.

[0152] The first line switch is used to connect the communication transmission interface, the baseboard management controller and the baseboard management controller memory.

[0153] The mainboard provided in some embodiments of the present application can apply the firmware burning method of the embodiments of steps 101 to 103, switch the first line conversion switch, so that the communication transmission interface and the baseboard management controller memory can be connected, and then the baseboard management controller memory can be burned through the terminal device. After the burning is completed, the first line conversion switch can be switched to connect the baseboard management controller and the baseboard management controller memory.

[0154] In some embodiments, the mainboard further comprises:

[0155] The second line transfer switch; wherein the three terminals of the second line transfer switch are respectively connected to the communication transmission interface, the first line transfer switch and the baseboard management controller.

In the figure, the RS232 interface can be welded to the SPI bus, the CPLD can be connected to the BMC, line transfer switch 1, line transfer switch 2, indicator light 1, indicator light 2, indicator light 3, switch 1 and switch 2, and the CPLD can communicate with the BMC via the system serial port and the BMC serial port. Under normal conditions, indicator light 1 is always on, and indicator lights 2 and 3 are off. When it is necessary to burn the BMC memory, an external device can send a burning indication signal to the CPLD via the RS232 interface via the UART line. The CPLD can respond to the burning indication signal and switch line transfer switch 1 via the control signal 1 line so that the BMC memory is connected to line transfer switch 2 via the SPI bus. At this time, indicator light 1 can be turned off and indicator light 2 can be turned on. Then, the RS232 interface can be connected to line transfer switch 1 via the SPI bus by switching line transfer switch 2 via the control signal 2 line. At this time, indicator light 2 can be turned off and indicator light 3 can be turned on, indicating that the switching of line transfer switch 1 and line transfer switch 2 is complete and burning can be performed. The CPLD can also disconnect switch 1 via power control line 1 and connect switch 2 via power control line 2, switching the system from the primary power source to the external power source. When programming is complete, the CPLD controls switch 1 and switch 2 to restore their initial states, turning indicator 3 off and indicator 1 on. Furthermore, the CPLD can disconnect switch 2 and connect switch 1, switching the system from the external device to the primary power source again. This completes the BMC memory programming process.
