Abstract

The invention discloses a method for programming STM32 cross-single-chip microcomputers, through the serial port short connection function of the bootloader (allowing the two serial ports of the single-chip microcomputer to perform protocol transparent transmission, so that the programming device bypasses the single-chip microcomputer and directly connects to the next single-chip microcomputer), When there is one or more single-chip microcomputers between the programming device and the target single-chip microcomputer, short-circuit these single-chip microcomputers in the middle, so that the burning device and the single-chip microcomputer to be burned can achieve the effect of direct connection, and then the burning software will burn the burning file Download to the specified address in the Flash of the single-chip microcomputer through the serial port to realize cross-single-chip programming; in addition, when directly connecting the single-chip programming program, it can be any serial port on the single-chip microcomputer, which removes the restriction that it can only be programmed from serial port 1.

Description

technical field [0001] The invention relates to a method for programming a single-chip microcomputer in the embedded field, in particular to a method for programming a program across an STM32 single-chip microcomputer. Background technique [0002] At present, there are three most commonly used methods for STM32 microcontroller programming: 1. Use MCUISP (very popular on the Internet) software to burn through serial port 1. 2. Use STM official software to burn through serial port 1; 3. Use the emulator to download the program. The above methods are all directly connected, that is, the programming device is directly connected to the target microcontroller to be programmed, and if method 1 or method 2 is used to program through the serial port, the official document clearly states that it can only be performed through the serial port 1. burn. However, method 3 requires a special JTAG or SWD interface for programming with an emulator, and cannot be programmed across computers...
