PROJECT STRUCTURE:

• GPIO: Includes a simple program that demonstrates how to blink LED on Nucleo F411RE
• shared: required to build a project
• To create a new project from template, run:

  $ tools/new_project.sh

TO DEBUG IN VSCODE:

• Install toolchain and openocd:

  $ sudo apt install gcc-arm-none-eabi gdb-multiarch openocd

• Install VSCode extensions: Cortex-Debug and C/C++

• Create launch.json:

{
  "version": "0.2.0",
  "configurations": [
      {
          "cwd": "${workspaceRoot}",
          "executable": "./output/output_fmw.elf",
          "name": "Debug with OpenOCD",
          "request": "launch",
          "type": "cortex-debug",
          "servertype": "openocd",
          "configFiles": [
              "/usr/share/openocd/scripts/board/st_nucleo_f4.cfg"
          ],
          "searchDir": [],
          "runToEntryPoint": "main",
          "showDevDebugOutput": "none"
      }
  ]
}

• Create settings.json:

{
    "cortex-debug.armToolchainPath": "/usr/bin",
    "cortex-debug.openocdPath": "/usr/bin/openocd",
    "cortex-debug.variableUseNaturalFormat": false
}

• Create c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "vscode_stm32_c_cpp_properties",
            "compilerPath": "/usr/bin/arm-none-eabi-gcc",
            "includePath": [
                "${workspaceRoot}/include/include/",
                "${workspaceRoot}/include/cmsis/include/",
                "${workspaceRoot}/include/drivers/inc"
            ],
            "defines": [
                "STM32F429xx"
            ],
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64",
            "configurationProvider": "ms-vscode.makefile-tools"
        }
    ],
    "version": 4
}

Building and Flashing Steps:

• COMPILE THE DEMO CODE (src/main.c) :

  $ make 

• FLASH :

  $ make flash

or

  $ stlink_flash.sh

or

  $ st-flash --reset write output/output_fmw.bin 0x8000000

or

  $ openocd -f /usr/share/openocd/scripts/board/st_nucleo_f4.cfg -c "program output/output_fmw.elf verify reset exit"

• CLEAN BINARIES (OPTIONAL) :

  $ make clean

• ERASE THE CHIP'S CONTENT (OPTIONAL) :

  $ make erase

• START THE DEBUGGING SESSION :

  $ make debug

• OPEN ANOTHER TERMINAL WINDOW, AND LET THE FUN BEGIN :

  $ make gdb

How to use from WSL:

• On Windows side:

 $ usbipd wsl list

following by:

 $ usbipd wsl attach --busid <busid>

• On Linux side (just to check):

 $ lsusb
