As shown in fig. 1, a first aspect of an embodiment of the present invention proposes a method for starting a baseboard management controller of a server, including:
step S1, loading a first starting program from a first memory chip;
step S2, responding to successful loading of the first starting program, and loading a second starting program of the baseboard management controller of the server based on the first starting program in a sectional mode;
and step S3, responding to failure of the second starting program of the sectional loading of the server baseboard management controller, writing the failed sectional point into a first parameter area of the first starting program in the first memory chip, and restarting the baseboard management controller of the server through the first starting program in the second memory chip.
In the invention, to solve the problem of failure in the starting process of a server baseboard management controller (hereinafter referred to as BMC), FIG. 4 shows a configuration reference diagram of the server baseboard management controller in the server, firmware issued by the server baseboard management controller is stored in SPI Flash hung on the server BMC, in order to improve the reliability of the firmware, two Flash are mounted on the BMC SPI controller in a SPI Flash redundancy mode, and firmware starting loading is realized in a SPI CS chip selection mode. The hardware watchdog CS chip selection mechanism is added on the hardware, the hardware watchdog is started after the BMC is electrified, and the CS chip selection signal is automatically switched when the watchdog is overtime, so that the function that the BMC loads firmware data from different Flash is realized, the BMC firmware contents stored in the two SPI Flash are completely the same, and the problem of BMC fault caused by hardware fault is effectively solved by using a physical redundancy mode.
In the embodiment of the invention, in step S1, when the BMC is started, a boot bootstrap program of about 8K is read from the SPI Flash1 and loaded by the gating SPI Flash1 with the CS watchdog default configuration under default conditions;
in step S2, after the boot loader is loaded into the BMC, the boot loader starts to run, and loads other functional programs of the subsequent BMC. The method comprises the steps that when other functional programs of a subsequent BMC are loaded, the other functional programs are loaded in a sectional mode;
in step S3, if the boot loader is loaded with any one of the other functional programs, it needs to determine whether the functional program is successfully installed, if the functional program is failed to install, the installation failure condition of the functional program is marked, and a configuration parameter area for storing the boot loader in the SPIFlash1 exists, so as to mark that the execution until the functional program fails to restart the BMC and reload when the functional program is loaded with the SPIFlash 1.
In some embodiments of the present invention, after the BMC is restarted after the BMC has failed to be started by using the SPIFASH 1, the BMC starts to execute the loading from the boot program with the size of 8KB in the SPIFASH 1. And finishing the loading of the boot loader and reading the relevant configuration parameters of the configuration parameter area of the boot loader, if the mark of the startup failure using the SPIFASH 1 stored in the previous startup process is found, controlling the CS watchdog to gate the SPIFASH 2 by the boot loader, and then starting the BMC from the SPIFASH 2 by the hot restart BMC.
In some embodiments of the present invention, loading a second boot program of a baseboard management controller of the server based on the first boot program in a segmented manner includes:
segmenting the second starting program according to the function type;
generating a special tag for the second boot program of any segment prior to loading the second boot program of the segment;
writing the special mark into the first parameter area of the first starting program;
and deleting the special mark of the segmented second boot program from the first parameter area in response to successful loading of the segmented second boot program.
In this embodiment, the process of writing the mark into the configuration parameter area of the boot program of the BMC according to the present invention does not separately write the mark after writing the corresponding segmented function program, but generates a special mark of the function program before loading the corresponding function program, and writes the special mark into the configuration parameter area of the boot program. When the function program is loaded, the boot loader deletes the special mark representing the function program. If the function program fails to be loaded, the boot loader may be blocked or the device may be restarted by the BMC interrupt, so that the special mark cannot be modified, and the special mark is just saved.
In some embodiments of the invention, the method further comprises:
judging whether the special mark exists in the first parameter area of the first starting program in the first memory chip or not in response to successful loading of the first starting program;
in response to the presence of the special flag, the baseboard management controller is switched to the second memory chip and restarted.
In this embodiment, if, when the BMC is started, the CS watchdog gates the SPIFlash1 by default, after loading the boot loader of the SPIFlash1, the boot loader reads the configuration parameters of the corresponding configuration area, and if a fault flag is found, the CS watchdog gates the SPIFlash2, and the BMC is restarted from the boot loader in the SPIFlash 2.
In some embodiments of the present invention, writing the special mark to the first parameter area of the first start-up procedure further comprises:
and acquiring an 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, the same procedure as that of starting the BMC at the SPIFlash1, if the boot loader in the BMC using the SPIFlash1 fails to start the related function program, the corresponding point of the function failure is also saved in the configuration parameters of the boot loader.
In some embodiments of the invention, the method further comprises:
judging whether the special mark exists in the first parameter area of the first starting program in the first memory chip or not in response to successful loading of the first starting program;
and when the first starting program loads a second starting program represented by the special mark, loading the second starting program from the second memory chip according to the address in the second parameter area.
In this embodiment, during the starting process of the BMC, the boot loader is a program on the SPIFlash1, and the configuration parameter of the boot loader has a special flag of the corresponding function program, and in this case, the firmware program corresponding to the function program in the corresponding SPIFlash2 may be read by another SPI controller 2 through the structure shown in fig. 5.

If the loading fails, the problem is that the data of the function program firmware in the SPIFASH 1 is damaged, if the loading is successful, the data of the function program firmware in the SPIFASH 2 is damaged, and if the program in the SPIFASH 1 is problematic, the special mark of the function program is stored (not deleted) in the configuration parameter area of the boot program in the SPIFASH 1. Similarly, if the program in the SPIFASH 2 has a problem, the special mark of the function program is saved (not deleted) in the configuration parameter area of the boot loader in the SPIFASH 2.
In some embodiments of the invention, the method further comprises:
and in response to the failure of loading of the second starting program, saving the special mark of the second starting program to a first parameter area of the first starting program of the first memory chip, and loading the second starting program from the second memory chip.

and loading the second starting program represented by the special mark from the first memory chip in response to the second starting program represented by the special mark on the second memory chip.
In this embodiment, as shown in the configuration structure of the BMC in fig. 5, the BMC is provided with two SPI controllers, namely, the SPI controller 1 and the SPI controller 2, and if the firmware of the function program in the SPIFlash1 and the SPIFlash2 is problematic, when the BMC is started, the corresponding firmware program can be read in a mode of combining the two spiflashes respectively, so as to realize the stability of starting the BMC. As long as two SPIFLash do not appear and the function program at the same position has faults, the stable starting of the BMC can be realized.
The method for storing and starting the firmware of the baseboard management controller of the server is based on the hardware architecture of the server, and the boot program is started by adding the external chip selection watchdog of the dual SPI Flash and matching with the boot partition of the firmware, so that the dual-partition redundancy backup of the firmware of the baseboard management controller is completed, the safety and stability of the firmware of the baseboard management controller are greatly improved, and the method has positive significance for running fault tolerance of the server.
