Method for burning programs across STM32 single-chip microcomputers

The invention discloses a method for burning programs across STM32 single-chip microcomputers. Through a serial port short circuit function of a bootloader (two serial ports of a single-chip microcomputer are enabled to carry out protocol transparent transmission, and a burning device is enabled to bypass the single-chip microcomputer and be directly connected to a next single-chip microcomputer),when one or more single-chip microcomputers are arranged between the burning equipment and the burning target single-chip microcomputers at intervals, the middle single-chip microcomputers are in short circuit connection, the burning equipment and the single-chip microcomputers to be burnt achieve a direct connection effect, and then burning software downloads burning files to designated addresses in Flash of the single-chip microcomputers through serial ports, so that the cross-single-chip microcomputer burning is achieved. In addition, a program is directly connected to the single-chip microcomputer and can be any
