Development using STM32CubeIDE (all platforms)

Installation:

  1. Install latest STM32CubeIDE (link)
  2. Install cmake4eclipse 2.1.4 extension (Help > Install new software...> Work with: https://raw.githubusercontent.com/15knots/cmake4eclipse/master/releng/comp-update/ select cmake4eclipse version 2.1.4 and install it) (Later version is not supported by project generator)
  3. For FreeRTOS-aware debugging, install the FreeRTOS plugin from here.
  4. Install some spell checker (e.g. Eclipse CDT includes one).

Generate and open the project:

  1. Generate a project file by running: python utils/build.py --generate-dfu --generate-cproject
  2. Open the project in the IDE (File > Import Projects from File System... > Select the root directory of this repository > Finish)
  3. Right click on the project and select Properties. Make sure the settings for Indexer is the same as on the screenshot below (sometimes, it does not get loaded). screenshot

💡Changes to the generated project are not tracked by git. The build is still driven by CMake; therefore, if you want to add a file or change some compiler settings, change it in CMakeLists.txt directly.

FAQ

Error in final launch sequence: Failed to execute MI command ... and a looong file path

screenshot of the error

This happens when a debug configuration contains an absolute path to the firmware. Just change it to a relative one (beginning with build/, or build\ on windows).

Stepping by instruction before the RTOS starts

Checkout the README.md of the Cortex-Debug extension:

As a general rule do not try to use stepping instructions before the scheduler of your RTOS has started - in many cases this tends to crash the GDB servers or leave it in an inconsistent state.

You can always disable FreeRTOS debugging by removing the line "rtos": "FreeRTOS" from .vscode/launch.json.
