Abstract
With the rapid development of information technology and the change of international situation, the requirements for autonomous controllability and data security are increasingly remarkable, some special industries and application fields begin to replace domestic equipment, the development of domestic key software and hardware is followed, and the rapid development of autonomous controllable, safe and reliable server equipment is increasingly important. The BIOS firmware updating method under the domestic server can update the BIOS firmware through a BMC management interface, avoids the inconvenience of repeatedly disassembling a BIOS chip and burning the BIOS firmware through a Flash burning tool, effectively improves the updating efficiency of the BIOS firmware, can also realize remote updating of the BIOS, and facilitates daily management and maintenance of equipment.
Description
Technical Field
The invention relates to the technical field of domestic processors, BMC, BIOS and the like, in particular to a BIOS firmware updating method under a domestic server.
Background
The demand for autonomously controllable, secure and trusted computing devices based on domestic processors is increasingly remarkable due to the current situation and the need for data processing, and particularly, the demand gradually starts to replace the domestic devices in some special industries and application fields.
The BIOS is used as an important component of the server, is used for storing basic input and output, power-on self-test and system self-starting programs of the server, and mainly provides the bottommost hardware setting and control for the server. The self-characteristic of the domestic processor is limited, when different memories and PCIE expansion devices are matched, the BIOS is required to be adapted, debugged and updated and verified frequently, and in addition, if the content of a BIOS chip is damaged in the using process, the system cannot be started, and the BIOS firmware also needs to be updated. The traditional BIOS firmware updating method is to take off the BIOS chip and burn the BIOS firmware to the BIOS chip by a Flash burning tool, and the method needs related tools and completely depends on manual work, so that once an operation error occurs, the burning fails.
The invention provides a BIOS firmware updating method under a domestic server, which switches an SPI link to a BMC and a BIOS chip by controlling an SPI _ SE L signal on an SPI channel selection chip through a GPIO of the BMC, and completes the updating of the BIOS firmware by using a firmware uploading and updating program under the BMC.
Disclosure of Invention
In addition, if the content of a BIOS chip is damaged in the using process of the equipment, the system cannot be normally started, and the BIOS firmware needs to be burnt again.
Aiming at the problems that a Flash special programming tool is needed when the BIOS firmware is currently programmed and completely depends on manual operation, and the programming of the BIOS firmware is failed once the operation is wrong, the method for automatically updating the BIOS firmware through the BMC management interface is designed by means of a firmware updating program in the BMC and necessary hardware design, the programming of the BIOS firmware can be completed remotely without entering a machine room, and the method has the advantages of strong universality, convenience in implementation and the like.
Drawings
To more clearly illustrate the design and implementation of the present invention, a hardware connection block diagram and a firmware update flow diagram are provided.
FIG. 1 is a hardware connection block diagram of the present method;
FIG. 2 is a schematic diagram illustrating a firmware update process of the present method.
Detailed Description
Embodiments of the invention are illustrated below with reference to the accompanying drawings:
according to the figure 1, the invention provides a BIOS firmware updating method under a domestic server, which mainly comprises a domestic CPU14, a BMC11, an SPI channel selection chip 12 and a BIOS chip 13, wherein in order to update BIOS firmware through a BMC management interface, an SPI channel selection chip 12 and an SPI _ SE L control signal are added during mainboard design, so that the switching of an SPI bus from the CPU14 to the BIOS chip 13 and from the BMC11 to the BIOS chip 13 can be realized, and further, the requirement of updating the BIOS firmware through the BMC is met.
As shown in fig. 2, the present invention provides a method for updating BIOS firmware in a home-made server, which comprises the following specific steps:
s21, logging in a BMC management interface;
s22, the BMC management interface receives the update request and gates the SPI link between the BMC and the BIOS chip;
s23, the BMC acquires the BIOS firmware to be updated;
s24, calling a firmware updating program under the BMC, and burning the BIOS firmware into the BIOS chip;
s25, switching the SPI link back to the CPU to the BIOS chip;
and S26, restarting the equipment.
When a user logs in a BMC management interface to update BIOS firmware, clicking a 'update BIOS' button under the interface, the BMC closes a request of a client, terminates an internal related process, sets a PSI _ SE L control signal to be high level through a GPIO, switches an SPI link from a CPU to a BIOS chip to a BMC, switches the control right of the BIOS chip to the BMC, selects the BIOS firmware to be updated according to a prompt, calls and executes a firmware update program to burn the BIOS firmware to the BIOS chip after the BIOS firmware is uploaded, sets an SPI _ SE L control signal to be low level after the firmware is burnt, switches an SPI link from the BMC to the BIOS chip back to the CPU to the BIOS chip and restarts equipment to complete the update of the BIOS firmware.
According to the BIOS firmware updating method, the BIOS chip does not need to be disassembled, all operations can be completed through the BMC management interface, meanwhile, the remote BIOS firmware can be updated, the implementation is convenient and fast, and the BIOS firmware updating efficiency is greatly improved.
