Summary of some open source libraries that drive MCU hardware debugger (including stlink debugger)

ST company-launched stm32 Single chip is widely used , To support program debugging , And better Downloads ,ST The company also launched the corresponding st-link Hardware Debugger , Pass through at one end USB Connecting to a computer , The other end JTAG perhaps SW Interface connection board . So how do users use st-link Download and debug the program ？（keil etc. IDE Download and debugging functions have been integrated , We don't talk about this ）

stlink Debugger is widely used , Therefore, open source libraries need to support at least stlink The debugger .

At least let users operate st-link There are several libraries for program download and debugging ：

OpenOCD

This open source library , It can not only control stlink, It can also control all other hardware debuggers , such as jlink etc. . Many people use it. , There are many online references .

See these blogs for details ：

The embedded IDE principle OpenOCD Introduce as well as stlink How to connect stm32 The board _ mark biao The blog of -CSDN Blog

Study with me OpenOCD( One ) - You know

stlink

This open source library ,GitHub - stlink-org/stlink: Open source STM32 MCU programming toolset

It can only be used for control stlink Hardware Debugger （ Other debuggers do not support ）, Yes stm32 Single chip microcomputer carries out Program download and debugging . Use fewer people , There is less information on the Internet . It mainly includes these tools ：

• st-info - a programmer and chip information tool, Used to view the information of programs and single chip computers
• st-flash - a flash manipulation tool, Used to put the target program xx.hex Download it to the board
• st-trace - a logging tool to record information on execution
• st-util - a GDB server (supported in Visual Studio Code / VSCodium via the Cortex-Debug plugin), Used to support stm32 MCU debugging
• stlink-lib - a communication library
• stlink-gui - a GUI-Interface [optional], In order to use the above tools more conveniently , A visual operation stlink The interface function of ,

Use , You can refer to this blog ：ubuntu Use st-flash_Gkbytes The blog of -CSDN Blog

We can compile this open source library by ourselves , You can also download the compiled exe, Link to ：Releases · stlink-org/stlink · GitHub

After downloading , Mainly a few exe The file , No installation required , Start command line window , Then the command line executes them , Just give the corresponding parameters

STM32 ST-LINK Utility

This Not open source ,ST The company specializes in its own stlink Launched visualization program download software , Support program download 、 Chip information reading 、 Memory erase and many other functions , however Can't debug . This tool is for batch downloading code , Used a lot .

summary

If only ST The company's stlink,stm32 Single chip microcomputer , that stlink Library will do , Support downloading and debugging . If you need to support other manufacturers' hardware debuggers and microcontrollers , Then use OpenOCD Well , For example, do it yourself IDE, Support various hardware debuggers , You have to use it. OpenOCD 了 .
