Problems solved by technology

In related technologies, CPLDs are generally upgraded under the control of a baseboard management controller (BMC, Baseboard Management Controller), and will go through a restart phase during the upgrade process. At this time, power control will not be possible, which will cause related controllers to appear down. The problem of power on and then on will affect the normal operation of the server host

Abstract

The invention provides a CPLD upgrading method and system, and a computer readable storage medium. The system comprises a substrate management controller, a master CPLD and a slave CPLD, the master CPLD sends a power supply control signal to a controller through the slave CPLD, and an upgrading effective signal is arranged between the substrate management controller and the slave CPLD. The method comprises the following steps: when the substrate management controller determines that the master CPLD completes upgrading preparation, setting the upgrade effective signal to be in an enabling state, enabling the slave CPLD to lock the current power supply control signal, and using the current power supply control signal to control the controller; controlling the master CPLD to carry out CPLD upgrading; when it is determined that CPLD upgrading is completed by the master CPLD, setting an upgrading effective signal to be in a forbidden state, enabling the slave CPLD to release the current power supply control signal, and controlling the controller by using the power supply control signal sent by the master CPLD; and keeping the previous power supply control signal when the master CPLD is upgraded, so as to keep the normal operation of the server.

Description

technical field [0001] The invention relates to the server field, in particular to a CPLD upgrading method, system and computer-readable storage medium. Background technique [0002] CPLD (Complex Programmable Logic Device) is also known as a complex programmable logic device, and its functions include power control for controllers on server motherboards and memory. In related technologies, CPLDs are generally upgraded under the control of a baseboard management controller (BMC, Baseboard Management Controller), and will go through a restart phase during the upgrade process. At this time, power control will not be possible, which will cause related controllers to appear down. The problem of power on and on again will affect the normal operation of the server host. Contents of the invention [0003] The purpose of the present invention is to provide a CPLD upgrade method, system and computer-readable storage medium, which can keep the power control signal sent to the contr...
