Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of server maintenance, and particularly relates to a BIOS flash switching detection method and device, equipment and a computer readable storage medium. BACKGROUND

[0002] The server needs to access and interact with the BIOS (Basic Input Output System) flash during startup. The existing method is to access and interact with the BIOS flash through the PCH (Platform Controller Hub) or CPU (Central Processing Unit). If the data read is incorrect, the system cannot start. The BMC (Baseboard Management Controller) in the server can also access and interact with the BIOS flash, mainly for BIOS flash updating, and the switching is performed through a multiplexer hardware.

[0003] Figure 1 For the BIOS flash switching architecture of the baseboard management controller, after the server is automatically powered on, the baseboard management controller accesses and interacts with the BIOS flash through the PCH or CPU, so that the server can start normally. When the baseboard management controller needs to update the BIOS flash, the server is controlled to shut down. After the server is shut down, the PCH or CPU will not communicate with the BIOS flash. At this time, the SPI (Serial Peripheral Interface) path is switched to the baseboard management controller, and the baseboard management controller can update the BIOS flash. After the update is completed, the SPI path is switched back to the PCH or CPU. If the baseboard management controller mistakenly switches the BIOS flash during startup, the PCH or CPU will fail to interact with the BIOS flash, thereby causing the server to fail to start. The operation and maintenance personnel need to measure the power sequence to locate the problem, and when the baseboard management controller switching time is very short, the problem locating (Debug) is more difficult, and even causes system crash.

[0004] To sum up, how to effectively solve the problem that the existing BIOS flash switching detection method is difficult to locate the problem when the baseboard management controller mistakenly switches the BIOS flash, and is easy to cause system crash is a problem that needs to be solved by the technical personnel in the field at present.

[0049] In order to make the personnel in the technical field better understand the present application scheme, the present application is further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0050] Reference Figure 2 , Figure 2 An embodiment flow chart of a BIOS flash switching detection method in an embodiment of the present application, which can include the following steps:

[0051] S201: Collect serial peripheral interface input signals input by a boot control end to a multiplexer.

[0052] The boot control end performs data access interaction operation with the BIOS flash through the multiplexer, and there is a signal between the multiplexer and the boot control end, and there is also a signal between the multiplexer and the boot control end. A complex programmable logic device (CPLD) is pre-set, and the programmable logic device is used to collect serial peripheral interface input signals input by the boot control end to the multiplexer in the server boot process.

[0053] The boot control end can be a PCH or a CPU.

[0054] S202: Collect serial peripheral interface output signals output by the multiplexer to the BIOS flash.

[0055] The programmable logic device is used to collect serial peripheral interface output signals output by the multiplexer to the BIOS flash in the server boot process.

[0056] S203: When it is determined that the serial peripheral interface input signal is inconsistent with the serial peripheral interface output signal, it is detected whether the switching signal of the baseboard management controller has a change, if yes, step S204 is executed, and if no, step S205 is executed.

[0057] After the serial peripheral interface input signal input to the multiplexer by the power-on control end is collected and the serial peripheral interface output signal output to the BIOS flash memory by the multiplexer is collected, it is judged whether the serial peripheral interface input signal is consistent with the serial peripheral interface output signal, when it is determined that the serial peripheral interface input signal is inconsistent with the serial peripheral interface output signal, it is indicated that the current server cannot be normally started, and it is detected whether the switching signal of the baseboard management controller has a change, such as whether the state flag bit has a change, if yes, it is indicated that the baseboard management controller attempts to update the BIOS flash memory in the process of starting the server, step S204 is executed, and if no, it is indicated that the baseboard management controller does not attempt to update the BIOS flash memory in the process of starting the server, step S205 is executed.

[0058] In one specific embodiment of the present application, detecting whether the switching signal of the baseboard management controller has a change can include the following steps:

[0059] It is detected whether the switching signal of the baseboard management controller is high.

[0060] It is pre-set that when the baseboard management controller updates the BIOS flash memory, the switching signal of the baseboard management controller will jump from low to high. When it is determined that the serial peripheral interface input signal is inconsistent with the serial peripheral interface output signal, it is detected whether the switching signal of the baseboard management controller is high. By detecting whether the switching signal of the baseboard management controller is high, it is determined whether the baseboard management controller mis-cuts the serial peripheral interface signal, clear determination of the baseboard management controller mis-cutting the serial peripheral interface signal is realized, and the problem positioning efficiency is improved.

[0061] In one specific embodiment of the present application, when it is determined that the serial peripheral interface input signal is inconsistent with the serial peripheral interface output signal, the method can further include the following steps:

[0062] The BIOS flash memory access interaction failure prompt information is output.

[0063] When it is determined that the serial peripheral interface input signal is inconsistent with the serial peripheral interface output signal, it is indicated that the current server cannot be normally started, and the BIOS flash memory access interaction failure prompt information is output, so as to timely prompt the operation and maintenance personnel that the server starting process is abnormal.

[0064] In one specific embodiment of the present application, the output BIOS flash access interaction failure prompt information can comprise the following steps:

[0065] The pre-set flash error prompt light is controlled to be lit to prompt the BIOS flash access interaction failure.

[0066] The flash error prompt light is pre-set, when the server boot process is normal, the flash error prompt light is in an off state by default, when the server boot process is abnormal, the flash error prompt light is lit. When it is determined that the serial peripheral interface input signal and the serial peripheral interface output signal are inconsistent, the pre-set flash error prompt light is controlled to be lit, thereby prompting the BIOS flash access interaction failure. By setting the flash error prompt light, whether the server boot process is normal or not can be more intuitively reflected.

[0067] S204: Determine that the baseboard management controller mis-cuts the serial peripheral interface signal.

[0068] In one specific embodiment of the present application, after step S204, the method can further comprise the following steps:

[0069] Step one: Obtain a first preset flag corresponding to the baseboard management controller mis-cutting the serial peripheral interface signal;

[0070] Step two: Set the first preset flag into a register.

[0071] For convenience of description, the above two steps can be combined for description.

[0072] The first preset flag corresponding to the baseboard management controller mis-cutting the serial peripheral interface signal is pre-set, for example, it can be set to 0x01. After it is determined that the baseboard management controller mis-cuts the serial peripheral interface signal, the first preset flag corresponding to the baseboard management controller mis-cutting the serial peripheral interface signal is obtained, and the first preset flag is set into the register. Thus, the baseboard management controller mis-cutting the serial peripheral interface signal is effectively recorded, thereby facilitating subsequent viewing and tracing.

[0073] S205: Determine that the serial peripheral interface signal has noise.

[0074] When it is detected that the switch signal of the baseboard management controller has no change, it is indicated that the baseboard management controller does not attempt to update the BIOS flash during the server boot process, and it is determined that the serial peripheral interface signal has noise.

[0075] In one specific embodiment of the present application, after step S205, the method can further comprise the following steps:

[0076] Step one: Obtain a second preset flag corresponding to the serial peripheral interface signal having noise;

[0077] Step two: set the second preset flag bit into the register.

[0078] For the convenience of description, the above two steps can be combined for description.

[0079] The second preset flag bit corresponding to the noise of the serial peripheral interface signal is set in advance, such as 0x02, after determining that the serial peripheral interface signal has noise, the second preset flag bit corresponding to the noise of the serial peripheral interface signal is obtained, and the second preset flag bit is set into the register. Thus, the serial peripheral interface signal with noise this time is effectively recorded, which is convenient for subsequent viewing and tracing.

[0080] From the above technical solution, by pre-setting the complex programmable logic device, the complex programmable logic device is used to collect the serial peripheral interface input signal input by the boot control end to the multiplexer and the serial peripheral interface output signal output by the multiplexer to the BIOS flash memory, respectively, to determine whether the serial peripheral interface input signal and the serial peripheral interface output signal are consistent, when it is determined that the serial peripheral interface input signal and the serial peripheral interface output signal are inconsistent, whether the switch signal of the baseboard management controller changes is detected; if there is a change, it is determined that the baseboard management controller mis-cuts the serial peripheral interface signal; if there is no change, it is determined that the serial peripheral interface signal has noise. Thus, the rapid and accurate detection of BIOS flash memory switching is realized, the problem positioning difficulty is simplified, and the system security is improved.

[0081] It should be noted that based on the above embodiment, the present embodiment also provides a corresponding improvement scheme. In the subsequent embodiments, the steps in the above embodiments or the corresponding steps can be mutually referenced, and the corresponding beneficial effects can also be mutually referenced. In the following improved embodiments, it will not be described one by one.

[0082] Reference Figure 4 , Figure 4 Another embodiment of the BIOS flash memory switching detection method in the present embodiment is provided, which can include the following steps:

[0083] S401: Collect the serial peripheral interface input signal input by the boot control end to the multiplexer.

[0084] S402: Collect the serial peripheral interface output signal output by the multiplexer to the BIOS flash memory.

[0085] S403: Determine whether each input branch signal of the serial peripheral interface input signal and each output branch signal of the serial peripheral interface output signal are consistent, if yes, do not process, if not, execute step S404.

[0086] After the serial peripheral interface input signal inputted by the power-on control end to the multiplexer is collected and the serial peripheral interface output signal outputted by the multiplexer to the BIOS flash memory is collected, it is judged whether each input branch signal of the serial peripheral interface input signal and each output branch signal of the serial peripheral interface output signal are consistent or not, if yes, it is indicated that the current server boot process is normal, no processing is performed, if not, it is indicated that there may exist the baseboard management controller attempting to update the BIOS flash memory in the server boot process, step S404 is executed.

[0087] Referring to Figure 3 , Figure 3 is a BIOS flash memory switching detection architecture diagram in the embodiment of the application. Four SPI signals of the PCH or CPU to the multiplexer and four SPI signals of the multiplexer to the BIOS flash memory are pulled to the complex programmable logic device, and the switch signal of the baseboard management controller is also provided to the complex programmable logic device. The SPI signal speed of the PCH or CPU can be up to 40 MHz, the complex programmable logic device can use the internal high-speed 133 MHz clock to detect whether the input and output signals of the multiplexer are the same, for example, BIOS_SPI_CS0 detects that it is a high level, SPI_CS also detects that it is a high level, and so on. The other BIOS_SPI_CLK_0 and SPI_CLK are compared, BIOS_SPI_Dout_0 and SPI_Dout are compared, and BIOS_SPI_Din_0 and SPI_Din are compared. When the complex programmable logic device detects that the input and output signals of the multiplexer are not the same, the complex programmable logic device will light the flash memory error prompt light. At the same time, the complex programmable logic device will also detect the switch signal sent by the baseboard management controller. If the switch signal is high, it indicates that the baseboard management controller cuts the serial peripheral interface signal to itself at present, at this time, if the PCH / CPU is still in the boot state, it cannot read the BIOS flash memory information, which will cause the system to fail to boot, and the complex programmable logic device will set the register as the baseboard management controller mis-cut. If the switch signal sent by the baseboard management controller is low, the complex programmable logic device will set the register as the serial peripheral interface signal has noise. The engineer can read the register of the complex programmable logic device through the baseboard management controller to know whether it is the baseboard management controller mis-cut or the serial peripheral interface signal has noise, which can reduce the engineer problem positioning (Debug) time.

[0088] S404: whether the switch signal of the baseboard management controller changes or not is detected, if yes, step S405 is executed, if not, step S406 is executed.

[0089] S405: Determine that the baseboard management controller mis-cuts the serial peripheral interface signal.

[0090] S406: Determine that the serial peripheral interface signal has noise.

[0091] The embodiment of the present application compares the serial peripheral interface signal sent by the PCH or the CPU to the multiplexer with the serial peripheral interface signal sent by the multiplexer to the BIOS flash memory at all times. When the two serial peripheral interface signals are different, the CPLD lights the flash error prompt light on the board and records the information, which is read by the baseboard management controller. Thus, it can be quickly determined whether the baseboard management controller mis-cuts the serial peripheral interface signal of the BIOS flash memory during the development stage, and the time for the engineers to locate the problem is reduced.

[0092] In a specific example application, the algorithm for how the CPLD detects the serial peripheral interface signal of the BIOS flash memory is described as follows.

[0093] 1) When the power is turned on, the CPLD continuously detects the serial peripheral interface signal sent by the PCH / CPU to the multiplexer and the serial peripheral interface signal sent by the multiplexer to the BIOS flash memory.

[0094] 2) When the CPLD detects that the two serial peripheral interface signals before and after the multiplexer are different, the CPLD further detects the switch signal of the baseboard management controller.

[0095] 3) If the CPLD detects that the switch signal of the baseboard management controller is high, the CPLD sets the baseboard management controller mis-cuts the serial peripheral interface signal to the register (0x01) and lights the flash error prompt light at the same time.

[0096] 4) If the CPLD detects that the switch signal of the baseboard management controller is low, the CPLD sets the information that the serial peripheral interface signal has noise to the register (0x02) and lights the flash error prompt light at the same time.
