Problems solved by technology

However, in the prior art, two CPLD chips are required, and the cost is high and the structure is relatively complicated; in addition, the redundancy mechanism is not considered, and if the communication between the two CPLDs is abnormal, one of the CPLDs may be restored by mistake

Abstract

The invention discloses a method for recovering a faulty CPLD, comprising the following steps: storing an upgrade file of the CPLD in a BMC; in response to the BMC writing data in a write-only register of the CPLD, judging whether the BMC can read and write the CPLD; Since the BMC cannot read and write the CPLD, it is judged whether the BMC detects the assignment signal of the CPLD to the GPIO; and in response to the BMC not detecting the assignment signal of the CPLD to the GPIO, the CPLD is updated based on the upgrade file. The invention also discloses a computer device and a readable storage medium. The method, device and medium for recovering a faulty CPLD proposed by the present invention ensure no misjudgment of the fault of the CPLD through a double judgment mechanism, improve the reliability of the overall system, and store the upgrade file of the CPLD in the BMC, thereby ensuring the recovery of the CPLD to the correct version.

Description

technical field [0001] The present invention relates to the field of servers, and more particularly, to a method, device and readable medium for recovering a faulty CPLD. Background technique [0002] For products such as unified storage / server / storage server, the management plane is basically composed of CPLD and BMC. CPLD is responsible for implementing Glue Logic (glue logic), and BMC is responsible for controlling the entire management plane. Since CPLDs are programmable logic devices, they may need to be frequently upgraded during actual operation, even including client-side upgrades. Since the CPLD implements the functions of Glue Logic in the system, once the CPLD upgrade fails, it is very likely to cause the entire system to fail. Therefore, it is necessary to have means to recover after the CPLD upgrade fails. [0003] In the prior art, by means of CPLD backup, after one CPLD fails to upgrade, the recovery can be controlled by another CPLD. However, in the prior ...
