STM32 and Simulink: failure at compile time, or: where is my library...

Hello all,

I'd like to try and get a basic model/program to run on an STM32 Nucleo H743ZI2. I have the following setup:

• Windows 10
• Matlab 2023b with Simulink and all the bells and whistles
• Simulink Coder Support Package for STMicroelectronics Nucleo Boards
• And the mentioned STM32 Nucleo H743ZI2

Pictured below is my model (warning, dangerously simple):

Building the code doesn't seem to be a problem. Compiling however...is. I'm getting the following message

Build process stopped at compile stage. Unable to find the following link-only objects that are specified in the build information: \Lib\GCC\arm_cortexm7ldfdp_math\libCMSISDSP.a

Somehow, the mentioned library can't be found. Does anyone have a clue why that might be? Thanks in advance!

Kind regards,

Bjorn

Hi, I got the same issue. Were you able to solve the problem?

Hi Cristhian,

yes, it turns out the Embedded Coder Support Package for ARM Cortex-M Processors was not installed correctly. After reinstalling, compiling worked fine.

Kind regards,

Hi Bjorn,

Thank you for your answer. After reading your answer I reinstalled Embedded Coder Support Package for ARM Cortex-M Processors from Add-Ons and still have the same issue. Did you do a different installation procedure?

Thank you in advance,

Cristhian

@Cristhian Chavez Try re-installing both Embedded Coder for ARM Cortex and Simulink Coder for STM32. Also, share your MATLAB version and the STM32cubeMX versions you are using.

Hi @Bjorn and @Hassaan,

Thank you both for your help. I could fix the problem after reinstalling MATLAB, Simulink Coder, Embedded Coder Support Package for ARM Cortex-M Processors and Simulink Coder Support Package for STMicroelectronics Nucleo Boards.

Kind regards,

libCMSISDSP.a. This library is part of the ARM Cortex Microcontroller Software Interface Standard (CMSIS).

1. Check the Library Path: Ensure that the path to the library is correctly specified in your project settings. The error suggests that it is looking for the library in \Lib\GCC\arm_cortexm7ldfdp_math\. Verify if this path is correct and if the library file actually exists at that location.
2. Install the CMSIS-DSP Library: If the library is not present in your system, you might need to download and install it. The CMSIS-DSP library is often included in ARM development environments or can be downloaded from the ARM website or through your development environment's package manager.
3. Correct Project Configuration: Make sure that your project is configured for the correct target processor. Since libCMSISDSP.a is specific to ARM Cortex-M7, your project should be set to build for this architecture.
4. Library Compatibility: Ensure that the version of the library is compatible with your development environment and toolchain. Sometimes, newer versions of IDEs or toolchains may require updated versions of libraries.
5. Rebuild the Project: After making the necessary adjustments, clean your project and rebuild it. This ensures that the build process starts afresh and picks up all the correct settings and paths.
6. MATLAB Packages for STM32:

Sorry for my late response, but I got it to work! One of the support packages -Embedded Coder Support Package for ARM Cortex-M Processors- was not installed correctly. Reinstalling fixed the issue.

Thank you for your answer!
