Problems solved by technology

[0003] In the prior art, the existing method for realizing switching is to control the CPU reset and the selection of the main Flash and the standby Flash by the CPLD. After loading BIOS from the main Flash fails, the CPLD selects the standby Flash and outputs a reset signal to the CPU. Realize that the CPU loads the BIOS from the standby Flash to start, and when the CPU is working, the firmware update to the Flash is completed. However, in the prior art, when both Flashes cannot load the BIOS, the firmware update fails, and when there is a lack of necessary update content , may lead to the problem that the CPU cannot load the BIOS normally, and the CPU cannot work

Abstract

On one hand, the invention relates to a Flash structure for realizing dual redundancy, and the structure comprises a control unit, and the control unit is electrically connected with a selection module; the control unit controls the selection module to be connected with the substrate management controller and the main Flash or the standby Flash, or controls the selection module to be connected with the CPU and the main Flash or the standby Flash; and the control unit is electrically connected with the substrate management controller and the CPU. On the other hand, the invention relates to a method for realizing the dual-redundancy Flash. The method comprises the following steps of: automatically switching the main Flash and the standby Flash to be connected with the CPU in a BIOS loading process; when the BIOS cannot be loaded, the main Flash and the standby Flash are automatically switched to be connected with the substrate management controller in the Flash upgrading process through the substrate management controller. According to the method and the device, Flash upgrading can be carried out on the CPU or the baseboard management controller, when the two Flash cannot load the BIOS, the CPU cannot work, and remote upgrading can be carried out through the baseboard management controller, so that the BIOS is easier to maintain and higher in reliability.

Description

Technical field [0001] The present application relates to the field of Flash design, and more particularly to the structure and method of realizing dual redundant Flash. Background technique [0002] The CPU is the core component of the computer device. When the CPU is started, it is necessary to load the BIOS from the flash; in the prior art, in order to ensure that the ability to load the BIOS is successful, Flash is redundantly designed, set a primary flash and one Alternate Flash; When it is not possible to load from the primary flash to the BIOS, automatically switch to another. [0003] In the prior art, the existing method of switching is to control the CPU reset and the selection of CPU reset and the main flash and alternate flash. When the BIOS is loaded from the primary flash, the alternate flash is selected by the CPLD, and the reset signal is output to the CPU. Implementing the CPU to load the BIOS from the alternate flash, and when the CPU is working, complete the fi...
