A method and device for flash online verification backup and update

Abstract

The present invention provides a method and device for flash online verification backup and update. The method includes the following steps: installing the flash of the target FW that has been burned into the slot of the target flash; in response to the server being powered on, the CPLD detects the FW information in the Flash, and compares the FW information with the information of the target FW that has been programmed; in response to the inconsistency between the FW information and the information of the target FW that has been programmed, the CPLD backs up the FW information to the backup Flash, and copies the FW information to the backup Flash. Delete the information; synchronize the target FW to the flash of the motherboard. By using the solution of the present invention, the space on the board can be saved, the cost of the BOM can be reduced, and all server motherboards with TPM interfaces can be adapted, and the research and development occupied by multiple Flash FW update rollback operations in the Debug stage can be solved. Time, improve the efficiency of debugging, and can also solve problems such as increased labor costs, low update efficiency, and error-prone.

Description

technical field [0001] The field relates to the field of computers, and more particularly to a method and device for flash online verification backup and update. Background technique [0002] TPM (Trusted Platform Module) is a chip that is planted inside a computer to provide a root of trust for the computer. The chip's specifications are set by the Trusted Computing Group. In October 1999, a number of IT giants jointly initiated the establishment of the Trusted Computing Platform Alliance (TCPA), which is committed to promoting a new generation of safe and reliable hardware computing platforms. In March 2003, TCPA was reorganized into Trusted Computing Group (TCG), hoping to formulate relevant standards and specifications for trusted computers in terms of hardware and software across platforms and operating environments, and proposed TPM specifications. The TPM security chip has a wide range of uses, and with special software, it can achieve: 1. Store and manage BIOS powe...
