Abstract

The invention discloses a method, a device and equipment for upgrading switch firmware based on an MCU (Microprogrammed Control Unit) and a medium. The method comprises the following steps of: firstly, acquiring a data packet corresponding to switch firmware by an MCU (Microprogrammed Control Unit), accessing a switch through a serial peripheral interface (SPI) communication protocol, and acquiring information of the switch; if the version information of the switch is inconsistent with the version information of the data packet, performing matching verification on the hardware information of the switch and the data packet; and if the matching verification is passed, writing the data packet into the Flash of the switch, and resetting the switch. In the process, the MCU can directly write the data packet into the switch through the SPI communication protocol, so that switch firmware upgrading is achieved, external hardware equipment is not needed, the switch firmware upgrading cost is reduced, and upgrading convenience and efficiency are improved.
