Remote firmware updating system and method for BMC chip

Abstract

The invention particularly relates to a remote firmware updating system and method for a BMC chip. A CS structure is adopted for the remote firmware updating system and method for the BMC chip. The system comprises the BMC chip and a local mirror image database, and the BMC chip is connected with the local mirror image database through a network; an ARM processor is adopted for the BMC chip and connected with an interface control logic module and a mirror image unpackaging and reconstitution logic module, and the interface control logic module is connected with an FLASH storage and a receivingcache; the local mirror image database is configured with a mirror image decomposition and compression algorithm module and a mirror image database module. According to the remote firmware updating system and method for the BMC chip, increment firmware mirror images can be quickly transmitted, and an updated mirror image can be restored without complete mirror images; particularly, the system andmethod are suitable for remote mirror image updating of firmware updating under the condition of only local modification or minimum function modification, a large amount of network transmission timecan be saved, and the refreshing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of IP core design and firmware upgrade, in particular to a BMC chip-oriented firmware remote upgrade system and method. Background technique [0002] The application range of multi-channel servers is more and more widely used in today's society. It has good stability, high security, and high computing efficiency, which has been recognized by the society. The vast majority of companies are using servers, and some companies use a large number. If it is necessary to upgrade the BMC (Baseboard Management Controller) firmware of multiple servers, it can be upgraded locally or remotely. If the server is updated remotely, especially if the network bandwidth where the server is located is low, this brings about the problem of server update efficiency. Especially when the firmware file is relatively large, but the firmware is only partially modified, the update efficiency will be very low. [0003] In the existing...

Problems solved by technology

These two methods generally use uncompressed original images, resulting in huge data files

In the case of remote firmware update, it causes a great waste of resources and low update efficiency

Especially when the firmware update is only a partial modification or a very small function modification, the update efficiency and thinking are even more low and backward

In addition, unencrypted images have insecure factors
