Information processing method and device

The invention relates to the technical field of information processing, and discloses an information processing method and device.Firstly, after handshake between a central processing unit and a single-chip microcomputer fails, the central processing unit sends handshake failure information to the single-chip microcomputer; after receiving handshake failure information, the single-chip microcomputer sends a low-level signal to a first interface of the central processing unit and sends a level reset signal to a second interface of the central processing unit; after the central processing unit receives the level reset signal, a restart operation is executed, and the central processing unit generates a configuration information clearing instruction according to the received low level signal and sends the configuration information clearing instruction to the first storage unit; and finally, after the first storage unit receives the configuration information clearing instruction, clearing the stored configuration
