I'm having the same problem after I downloaded the new version of F24 Repository (V1.25).

Found the issue.

It happened when I copied the project into a new PC where I haven't downloaded (installed) the Middleware I'm using (CMSIS). After installing the Middleware properly, I was able to generate the code.

This is different from the "&" directory name issue mentioned above but the hang up issue is the same.

Yes, that was my problem as well!


Make sure that you don’t have specific signs like « #&% » in the path of your project folder or cubeMx library

I had the same problem because I had a « # » in the path of my folder project. Make sure you have only letters or number in yours different pathes wich are in relation with Cubemx

I had the same problem. "Project Location" must be near the Firmware Package folder, and all will be ok)

Yes, Thats Works.


Hi, I had the same problem but nothing from this not help to me. Finally I delete all folders in project folder without *.ioc CubeMX file. Next, I copy all folders of project from old compilation copy and generate code again and This help for me. It looks that CubeMX generate something inside folders of project before and next This data blocking Cube during next time to finish generate proccess. But, I don't know what exacly It was be.


Hi at all,

i solved the problem by not using special characters (&#%$§) in the path folder of the sources.
