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

Embodiment Construction
[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0043]CPLD is generally upgraded under the control of the baseboard management controller (BMC, Baseboard Management Controller). During the upgrade process, it will go through a restart phase. At this time, power control will not be possible, which will cause related controllers to be powered off and then powered on again. The problem, which...

The invention provides a CPLD upgrading method, system and computer-readable storage medium. The system includes a baseboard management controller, a master CPLD and a slave CPLD. The master CPLD sends a power control signal to the controller through the slave CPLD. The baseboard management controller and the slave CPLD There is an upgrade validation signal between them, and the method includes: when the baseboard management controller determines that the master CPLD completes the upgrade preparation, the upgrade validation signal is set to an enable state, so that the slave CPLD locks the current power control signal, and uses the current power control signal Control the controller; control the main CPLD to upgrade the CPLD; when it is determined that the main CPLD has completed the CPLD upgrade, set the upgrade effective signal to a disabled state, so that the slave CPLD releases the current power control signal and uses the power control signal sent by the main CPLD Control the controller; when the main CPLD is upgraded, its previous power control signal can be maintained to keep the server running normally.
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...
