Duplicate system_stm32g0xx.c file after regenerating

CTapp.1 · ‎2025-04-22

I've got a project that has the following files in the tree view:

All is well if I clean and build, but if I open the .ioc and "Generate Code", the tree changes to:

and the project then fails to build due to a duplicate system_stm32g0xx.c file.

Why is this getting added and how do I stop it?

I am using STM32CubeIDE V1.18.1.

I have created a new workspace and recreated the project from the .ioc file, and it looks like everything is back to normal.

I guess that means something in the workspace's metadata was not valid?

Hello @CTapp.1

First let me thank you for posting.

Could you please provide your IOC.

I 'will be waiting for your feedback.

Thanks for the quick response - file is attached.

Hello @CTapp.1

I used your IOC to generate the code multiple times and each time the build finished without any errors or warnings, and your project architecture did not change.

Let's try to close STM32CubeIDE and STM32CubeMX and go under C:\Users\XXXXXX then delete .stm32cubeide and .stm32cubemx.

Thanks - I've tried that, but the results are the same.

I've just uninstalled and reinstalled CubeIDE (V.1.18.1), but that has also made no difference.

Hello @CTapp.1

Try to use STM32CubeMX 6.14.1 standalone : this is the LINK to download it .

Open your IOC using STM32CubeMX 6.14.1 standalone then generate the code using STM32CubeIDE as shown

I will be waiting for your feedback.

Hi @Ghofrane GSOURI

The code is generated as expected when using the standalone MX 6.14.1 - the second system_stm32g0xx.c is not generated in the templates folder, and the code builds successfully.

Does this mean there is an issue with the integrated MX in IDE V1.18.1?

Edited to add:

When using the internal MX, an mx.scratch file is left in the project after code generation.

Hello @CTapp.1

Even with the integrated MX in IDE V1.18.1, everything is working correctly. After multiple generation of the code, the build finished with success. There were no changes in the structure of your project and no duplicate files.

It could be an issue related to your environment.

Ok, but how do I find out where the problem is so that I can fix it?
