As shown in fig. 1, a first aspect of an embodiment of the present invention provides a method for starting a baseboard management controller of a server, including:
step S1, loading a first startup program from the first memory chip;
step S2, responding to the successful loading of the first startup program, and loading a second startup program of a baseboard management controller of the server in a segmented mode based on the first startup program;
step S3, in response to failure of the second boot program for the server baseboard management controller, writing the failed segment point into the first parameter area of the first boot program in the first memory chip, and restarting the baseboard management controller of the server through the first boot program in the second memory chip.
In the present invention, what the present invention is to solve is a problem of a failure in a starting process of a server baseboard management controller (hereinafter abbreviated as BMC), fig. 4 shows a configuration reference diagram of the server baseboard management controller in a server of the present invention, firmware issued by the server baseboard management controller is stored in an SPI Flash external to the BMC of the server, in order to improve reliability of the firmware, two flashes are currently mounted on the BMC SPI controller in an SPI Flash redundancy manner, and firmware starting and loading are realized in an SPI CS chip selection manner. A hardware watchdog CS chip selection mechanism is added on hardware, a hardware chip selection watchdog is started after the BMC is powered on, a CS chip selection signal is automatically switched when the watchdog is overtime, the function that the BMC loads firmware data from different flashes is realized, BMC firmware contents stored in two SPI flashes are completely the same, and a physical redundancy mode is used, so that the problem of BMC failure caused by hardware failure is effectively solved.
In the embodiment of the present invention, in step S1, when the BMC is started, a boot loader of about 8K is read from the SPI Flash1 by using the strobe SPI Flash1 with the default configuration of the CS watchdog in the default case;
in step S2, after the boot program is loaded to the BMC, the boot program starts to run, and other subsequent functional programs of the BMC are loaded. When loading other subsequent functional programs of the BMC, loading other functional programs in a sectional mode;
in step S3, if the boot loader needs to determine whether the boot loader has been successfully installed in any of the other loaded function programs, if the boot loader has failed to be installed, the boot loader is marked as having failed to be installed and stored in the configuration parameter area of the boot loader stored in the SPIFlash1, so as to mark that the boot loader has failed to be executed when being loaded by using SPIFlash1, and the BMC is restarted and reloaded.
In some embodiments of the present invention, after the BMC is restarted after failing to boot up due to the use of the SPIFlash1, the BMC then starts to perform the load from the 8KB boot loader in the SPIFlash 1. And after the boot program loads and finishes reading the relevant configuration parameters of the configuration parameter area of the boot program, if a starting failure mark which is saved in the previous starting process and uses SPIFlash1 is found, the boot program controls the CS watchdog to gate the SPIFlash2, and then the hot restart BMC starts the BMC from the SPIFlash 2.
In some embodiments of the present invention, the step of loading the second boot program of the baseboard management controller of the server based on the first boot program in a segment comprises:
segmenting the second starting program according to the function type;
generating a special mark of the second starting program of any section before loading the second starting program of the section;
writing the special mark into the first parameter area of the first boot program;
in response to successful loading of the segmented second boot program, deleting the special token of the segmented second boot program from the first parameter area.
In this embodiment, in the process of writing the flag into the configuration parameter area of the boot program of the BMC, the flag is not written after the corresponding segmented functional program is written separately, but before the corresponding functional program is loaded, the special flag of the functional program is generated and written into the configuration parameter area of the boot program. When the functional program is loaded, the boot bootstrap program deletes the special mark which is stored previously and represents the functional program. If the function program fails to be loaded, the boot program may be jammed or the device may be restarted by the interrupt of the BMC, and the special mark cannot be modified, so that the special mark is just saved.
In some embodiments of the invention, the method further comprises:
responding to the successful loading of the first starting program, and judging whether the special mark exists in the first parameter area of the first starting program in the first storage chip or not;
and responding to the existence of the special mark, switching the baseboard management controller to the second storage chip and restarting the baseboard management controller.
In this embodiment, if when the BMC is started, the CS watchdog gates the SPIFlash1 in the default condition, and after the boot program of the SPIFlash1 is loaded, the boot program reads the configuration parameters of the corresponding configuration area, and finds that there is a fault flag, the CS watchdog gates the SPIFlash2, and the BMC is restarted from the boot program in the SPIFlash 2.
In some embodiments of the present invention, writing the special mark to the first parameter area of the first startup procedure further comprises:
and acquiring the address of the segmented second starting program represented by the special mark in a second memory chip, and storing the address in a second parameter area of the first starting program in the first memory chip.
In this embodiment, as in the process of starting the BMC in SPIFlash1, if the boot program in SPIFlash1 fails to start the related function program in the BMC, the corresponding point of function failure is also saved in the configuration parameters of the boot program.
In some embodiments of the invention, the method further comprises:
responding to the successful loading of the first starting program, and judging whether the special mark exists in the first parameter area of the first starting program in the first storage chip or not;
and when the first boot program loads a second boot program represented by the special mark, loading the second boot program from the second storage chip according to the address in the second parameter area.
In this embodiment, during the boot process of the BMC, the boot loader passes through the program on the SPIFlash1, and the configuration parameter of the boot loader has a special mark of the corresponding function program, and in this case, the firmware program corresponding to the function program in the corresponding SPIFlash2 can be read by another SPI controller 2 in the structure shown in fig. 5.
In some embodiments of the invention, the method further comprises:
in response to the first startup program being successfully loaded, respectively acquiring the second startup program from the first memory chip and the second memory chip, and comparing the second startup program acquired from the first memory chip and the second memory chip;
in response to the comparison result of the second starting programs obtained from the first storage chip and the second storage chip being different, judging the loading result of the different second starting programs;
and in response to the successful loading of the second boot program, saving the special mark of the second boot program to a first parameter area of the first boot program of the second memory chip.
In this embodiment, as shown in fig. 5, the BMC obtains the started firmware programs from SPIFlash1 and SPIFlash2 at the same time, but preferentially loads the boot program in SPIFlash1, and compares the obtained programs in the two flashes one by one, and when the comparison result is different, it may indicate that 1 firmware program has a problem (it may be that the stored data is damaged, or a write error occurs when data is written), and at this time, preferentially loads the functional program of SPIFlash 1. If the loading fails, it indicates that the data of the firmware of the functional program in SPIFlash1 is damaged, if the loading succeeds, it indicates that the data of the firmware of the functional program in SPIFlash2 is damaged, and if the program in SPIFlash1 is damaged, the special flag of the functional program is saved (not deleted) in the configuration parameter area of the boot loader in SPIFlash 1. Similarly, if a problem occurs in the program in SPIFlash2, the special flag of the function program is saved (not deleted) in the configuration parameter area of the boot loader in SPIFlash 2.
In some embodiments of the invention, the method further comprises:
and in response to the loading failure of the second boot program, saving the special mark of the second boot program to a first parameter area of the first boot program of the first storage chip, and loading the second boot program from the second storage chip.

In this embodiment, as shown in the configuration structure of the BMC shown in fig. 5, the BMC includes two SPI controllers, i.e., SPI controller 1 and SPI controller 2, and if the firmware of the functional programs in spilash 1 and spilash 2 has a problem, the corresponding firmware programs can be read in a manner of being combined from the two spilash respectively when the BMC is started, so as to achieve the stability of the start of the BMC. As long as two SPIFlash do not have the fault of the functional programs at the same position at the same time, the stable start of the BMC can be realized.
