Abstract:
A CPLD upgrade method and system, and a computer-readable storage medium, the system comprising a baseboard management controller, a master CPLD, and a slave CPLD. The master CPLD sends a power control signal to a controller by means of the slave CPLD, and an upgrade-effective signal is provided between the baseboard management controller and the slave CPLD. The method comprises: when the baseboard management controller determines that the master CPLD has finished preparing to upgrade, setting the upgrade-effective signal to an enabled state, such that the slave CPLD locks a current power control signal, and using the current power control signal to control the controller (S101); controlling the master CPLD to upgrade the CPLD (S102); and when it is determined that the master CPLD has completed the CPLD upgrade, setting the upgrade-effective signal to a disabled state, such that the slave CPLD releases the current power control signal, and using the power control signal that is sent by the master CPLD to control the controller (S103). The method can maintain a previous power control signal of a master CPLD when same is upgraded, so as to maintain normal operation of a server.
