The invention discloses a PCIe switch upgrading method and device, equipment and a storage medium, and relates to the technical field of computers, and the method comprises the steps: switching a universal asynchronous receiver/transmitter path of a debugging module located on a mainboard currently to a target universal asynchronous receiver/transmitter path connected with a PCIe switch upgrading module when a target in-place signal is detected to be in place, sending an upgrading preparation instruction generated by the PCIe switch upgrading module to the to-be-upgraded PCIe switch through the target universal asynchronous receiver-transmitter channel so as to send an upgrading preparation response to the PCIe switch upgrading module, and after the to-be-upgraded PCIe switch receives an upgrading command containing to-be-upgraded firmware sent by the PCIe switch upgrading module, upgrading the to-be-upgraded firmware to the to-be-upgraded PCIe switch. And carrying out upgrading operation by utilizing the to-
