Debug STM32 Helloworld Project with Vscode

STM32-HelloWorld

Installed in your computer

• ARM ToolChain
• SMT32cubemx
• JLink

sudo apt install openocd

Installed in your Vscode

• STM32 for VSCode
• Cortex-Debug

Create Project

open SMT32cubemx and create a Makefile project under Project Manager->Project->Toolchain/IDE. Also please leave the default on Copy all used libraries into the project folder.

Configure system core enable J-Link Debug under Pin & Configuration->System Core->sys->mode

Finally click to Generate Code in STM32cubemx

Configure Project

Open project of generated by STM32cubemx with VScode and build once time project run commnad stm32: build stm32 project by keydown ctrl+shift+p. Download svd file from cmsis-svd-data and place to root directory of project

Now. change openocd.cfg to following content

#OpenOCD configuration file, generated by STM32 for VSCode

# Programmer, can be changed to several interfaces
# Standard will be the stlink interface as this is the standard for STM32 dev boards
# source [find interface/stlink.cfg]
source [find interface/jlink.cfg]
transport select swd

# The target MCU. This should match your board
source [find target/stm32f1x.cfg]

change launch.json to following content
