description The invention provides an equipment operation method for firmware upgrading of a microcontroller unit. The equipment operation method comprises the following steps: starting up or restarting equipment; running the bootstrap program; determining to execute any one or more of the following steps according to the judgment result of the bootstrap program on the upgrading mark type of the equipment, and waiting to enter a core upgrading process when the upgrading mark is a first upgrading mark; when the upgrading mark is a second upgrading mark, running the application program until the upgrading command is received next time; and when the upgrading mark is a third upgrading mark, setting the upgrading mark as a second upgrading mark, running the application program, and after the application program runs successfully, setting the application program as an effective application program until the upgrading command is received next time. According to the equipment operation method and system, the problems that the b
