Abstract

The invention discloses a system and a method for supporting Flash burning of a server main control board. The system comprises a main board supporting two paths of central processing units, wherein acentral processing unit, an integrated south bridge, a substrate management controller, a complex programmable logic device, a central processing unit flash memory and a substrate management controller flash memory are arranged on the mainboard; the baseboard management controller and the integrated south bridge are electrically connected with the complex programmable logic device; the complex programmable logic device is connected with the central processing unit flash memory and the baseboard management controller flash memory through the same bus, and the complex programmable logic deviceachieves read-write operation of the central processing unit flash memory or the baseboard management controller flash memory through state selection of the chip selection bus. According to the invention, a chip holder for installing a flash memory in a traditional server is removed, and when the flash memory needs to be burnt, the main control board only needs to be connected to an upper computerthrough a combined test work group link for operation, so that the problems caused by the use of the chip holder are fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a system and method for supporting flash programming of a main control board of a server. Background technique [0002] At present, the main control board of a general-purpose server has two flash memory chips, one of which is used to store the BIOS, and the other is used to store the BMC operating system of the baseboard management controller. Usually, these two chips are used in the board design and verification stages. Installed on the chip holder Socket, it is disassembled for programming when updating the BIOS and the baseboard management controller (BMC) operating system. [0003] For hardware connection, see the attached figure 1 As shown, the flash memory Flash chip is mounted under the main control chip. The main control chip can be a baseboard management controller BMC or an integrated south bridge PCH, and the flash memory Flash chip must be a device with an SPI inter...
