STM32CubeIDE project with embedded coder files

Hi everyone,

I am starting with embedded coder for an stm32 (the BG474EDPOW board) and my goal is to be able to use STM32CubeIDE as a debugging tool and also be able to compile the generated code from Simulink Embedded Coder.

I am able to do my simulink model and use build deploy and start, it works on the board but the issue I am having is having a working project in the STM32CubeIDE.

Before generating my code I created the .ioc with CubeMX and in the target hardware ressource i chose the wanted .ioc file.

After generating the code, i have many files generated, so an ert_main.c, a project.c etc etc, but I want to have files that can be used in a STM32CubeIDE project, which I feel is not the case right now as I would have to copy and paste certain files, and certain parts of the code into the main.c file in the STM32CubeIDE project.

My question is : is there a way to direclty create a project with embedded coder / simulink that can be opened in STM32CubeIDE and which can be buildable / debuggable etc ?

For instance, when using embedded coder for TI targets, so for example C2000 targets, when generating the code there is a project which can be opened direclty in CCS and which can be build/debugged etc in CCS.

Is that possible for STM32 targets ? Am I missing a step ?

Thank you very much for your answers.

Hello,

Thank you for your answer.

This works partially, as the debugging is done but you can't see line per line what happens in your code.

Secondly, I would like to be able to open the generated project on stm32cubeIde, and be able to add code lines and modify the code and then build it using stm32cubeIDE but that does not seem to be possible. Am I missing something or is that feature just not doable ?

Thank you.

Hi Sarah. I have recently been having the same problem and were wondering what conclusion you came to?The other method im considering is haveing a base cube ide program and then genrating my control code as C which I then integrate into the project.

Hi Sarah,

Importing generated project in CubeIDE is currently not supported. You can use the method stated in https://www.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/stm32cubeide.html for debugging. Alternatively you can also debug using Import option for elf in CubeIDE.

Go to File --> Import --> C/C++ --> STM32 Cortex-M executable

Provide your .elf and select the relevent MCU. You can now press next to land on a debug configuratiuon screen and start debugging.

You should check the following if line by line debugging has problems:

1. Check if you have selected "Debug" as build configuration while performing code build in Simulink.
2. If you choose "Specify" in the build options, there should be "-g" compiler flag added. Also the optimization should be set to O0 as part of compiler flags. This is to ensure that debug symbols are added during elf creation.

Once debugging starts, you can open an individual file and keep breakpoints.

Regards,

Sagar

Hi

As per my understanding, you would like to integrate Simulink generated code with STM32CubeIDE for debuggging and deployment on STM32 hardware.

Refer to the steps provided in the following documentation to debug and deploy Simulink generated code on STM32 hardware:

https://www.mathworks.com/help/ecoder/stmicroelectronicsstm32f4discovery/ug/stm32cubeide.html

Hope this helps!

Hello,

The documentation link provided above is designed to assist in debugging Simulink-generated code using STM32CubeIDE. This process involves loading the generated .elf file into STM32CubeIDE for debugging after a successful model build.

Currently, direct code modification of Simulink generated code and building it within STM32CubeIDE is not supported. However, a workaround exists: you can modify portions of the code in the generated source files and then rebuild the model in Simulink to produce an updated .elf file. You can then re-initiate debugging in STM32CubeIDE.

Note: If you change the model or configuration parameters, the Simulink will regenerate the complete code, and any custom changes made to the Simulink generated source file will be lost. Therefore, this workaround is only effective if you do not modify the model or configuration parameters.

Alternatively, you can add custom source/code by navigating to Configuration Parameters -> Code Generation -> Custom Code. For more details, please refer to the https://www.mathworks.com/help/rtw/ref/code-generation-pane-custom-code.html. In this method, even if you change the model or configuration parameters, the changes made by you in custom source/code will not be lost on code regeneration from Simulink.

Hope this will be helpful !

Regards

Saurav

Hi Narvik,

Thanks for the documents. But the project import phase still throws error. CubeIDE doesn't actually the model based design project but just some other config files.

Looks like after following the steps, it just creates an empty file / default file with no configurations done in the .elf file.
