The invention provides a debugging method, device and equipment for a single-chip microcomputer, and relates to the technology of single-chip microcomputers, the method comprises the steps that a control instruction sent by an upper computer is received through a USB interface, and the control instruction is an instruction conforming to a USB protocol; converting the control instruction into a debugging instruction conforming to a JTAG protocol; sending a debugging instruction to the second single-chip microcomputer through the JTAG interface, wherein the debugging instruction is used for indicating the second single-chip microcomputer to execute a debugging task indicated by the debugging instruction and generate debugging result information; and receiving debugging result information sent by the second single-chip microcomputer, and sending the debugging result information to an upper computer through the USB interface. According to the method, for the second single-chip microcomputer to be debugged, the up
