Abstract

The invention discloses a CPLD firmware updating method, and the method comprises the steps: storing a CPLD firmware updating file in an established TFTP file server in advance; employing the safer SMASH CLP of the BMC for replacing the original SSH, and acquiring the CPLD firmware updating file from the TFTP file server in cooperation with the TFTP file transmission protocol, so that the CPLD firmware can be updated as well, and the problem that the CPLD firmware cannot be updated when the scp function and the ssh function of the BMC are closed is solved. The invention further discloses a CPLD firmware updating system and device. The CPLD firmware updating system and device have the same beneficial effects as the CPLD firmware updating method.

Description

technical field [0001] The invention relates to the field of servers, in particular to a method, system and device for updating CPLD firmware. Background technique [0002] Currently, a CPLD (Complex Programmable Logic Device, complex programmable logic device) in a server system is used to manage resources of a server board. In the prior art, the update method of CPLD firmware comprises: use scp instruction (file duplication instruction), CPLD firmware update file is copied to the internal memory of BMC (Board ManagerController, baseboard management controller) from update control device; Use SSH (Secure Shell , secure shell protocol) tool to log in to the BMC system, to control the BMC to update the CPLD based on the CPLD firmware update script (i.e. the CPLD firmware update tool) and the CPLD firmware update file. However, based on security considerations for the BMC in the server system, the scp function and ssh function of the BMC are sometimes turned off, resulting in...
