Fail to debug Nucleo STM32F429ZI

Hi I cannot connect to my Nucleo STM32F429ZI using STM32CubeIDE, the error message is:

Does anybody has an idea about what is wrong ?

And can you find that exefile at given location?

IIRC this error occurs if you import a project from other computer where CubeIDE (or other Eclipse) is installed in different path.

The path is captured in the debug configuration and the IDE is not smart enough to fix it.

Try to delete the debug config and create new.

Hello, thanks for your answers.

I don't think it comes from the exe file because it works with another card.

I tried directly to connect with the CLI. With the card that is working, the result is:

=> the CLI says my STM32F429ZI has 64 MBytes flash! I am not sure it can be a software issue.

Do you think MCU is damaged?
