Method, system and device for avoiding CPLD version updating errors, and storage medium

Abstract

The invention provides a method, system and device for avoiding CPLD version updating errors, and a storage medium. The method comprises the following steps that S1, a BMC judges a CPLD updating modeaccording to an application scene; S2, the BMC calculates a CPLD target version number according to the CPLD updating mode and the CPLD current version number; and S3, the BMC acquires the to-be-updated firmware of the CPLD, compares whether the version number of the to-be-updated firmware of the CPLD is consistent with the target version number of the CPLD, updates the firmware of the CPLD when the version numbers are consistent, and re-acquires the to-be-updated firmware of the CPLD when the version numbers are inconsistent. According to the method, the version number of the CPLD firmware isconfirmed by distinguishing four elastic updating modes so that a tester is prevented from updating to an unexpected CPLD firmware version, an error rate of the CPLD firmware updating version by a BMC (Baseboard Management Controller) is effectively avoided, the function verification result is ensured, and the verification time of the tester is shortened.

Description

technical field [0001] The invention belongs to the technical field of firmware update, and in particular relates to a method, system, equipment and storage medium for avoiding updating CPLD version errors. Background technique [0002] CPLD, short for Complex Programmable Logic Device, complex programmable logic device. [0003] BMC, the abbreviation of Baseboard management controller, baseboard management controller. [0004] CPLD is designed in server motherboard design, its main function is to control the power sequence of all chips on the motherboard, but in the design and development stage, the control of CPLD version is extremely important, if the CPLD cannot be updated effectively and correctly to the correct version , will cause the CPLD to be unable to cooperate with the current hardware design, the impact will be serious and even the circuit will be burned, resulting in the problem that the system cannot be turned on or the function is not complete, and the updat...

Problems solved by technology

[0004] CPLD is designed in server motherboard design, its main function is to control the power sequence of all chips on the motherboard, but in the design and development stage, the control of CPLD version is extremely important, if the CPLD cannot be updated effectively and correctly to the correct version , will cause the CPLD to be unable to cooperate with the current hardware design, the impact will be serious and even the circuit will be burned, resulting in the problem that the system cannot be turned on or the function is not complete, and the update version is wrong, which will also cause a waste of testers' verification time and verification results

[0005] In the existing server motherboard design, there are two ways to burn CPLD. One method is to use the burning cable provided by the CPLD manufacturer, and update the CPLD through the burning cable and the burning software provided by the CPLD manufacturer. , but not everyone has a programming tool at the production line or client end, and the system is covered with a case, it is even more troublesome to update the CPLD with a fixture, so this method is not practical; Another traditional method is to use the BMC to update the CPLD. This method only requires the BMC developer to provide an option to update the CPLD on the update interface, and let the user upload the updated version of the CPLD, and then update the CPLD. However, there is a problem with this method, which is When the user updates the CPLD through the BMC, the wrong CPLD version may be updated, and the update error can only be known by reading the version after the CPLD update is completed, which will waste the tester's verification time and affect the verification result.
