Not possible to Run/Debug on the evaluation board STM32F446RE Nucleo-64

Refused_HC · ‎2026-01-30

Hello all,

I have created a project with STM32CubeMx based on this evaluation board:

I generate the source code, and I can compile it correctly from STM32CubeIDE.

The problem is when I try to Run or Debug it, I get this message:

If anyone can help me I would appreciate it.

Much thanks in advance.

Hello @Refused_HC

Let's try to clean and rebuild your project by following those steps:

In STM32CubeIDE : right click on your project and then clean project as shown below

Then rebuild your project , confirm that the build generates an .elf file

Finally launch your debug session.

Thanks Ghofrane, but cleaning the project I still get the same error.

Hello @Refused_HC

Could you please provide your IOC so that I can test it?

It looks like your Debug Configuration is wrong - it is trying to use .cproject as the executable.

The executable name should be <project-name>.elf

PS:

Like this:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
