Debugging Issue with STM32CubeIDE

Hello,

I am encountering an issue while debugging a project using STM32CubeIDE. The problem arises when I start the debugging process. Below is the output from the console:

Open On-Chip Debugger 0.12.0+dev-00597-ga5a21219f (2024-06-03-11:04)

It seems to repeatedly halt due to a breakpoint, and there’s an "undefined debug reason 8 (UNDEFINED)" error message indicating that the target needs a reset. The debugger appears to lose the connection after this.

Could  please provide guidance on how to resolve this issue or any suggestions on what might be causing it?

Thank you.

Is this a genuine ST chip or a counterfeit product? The vast majority of these chips are not genuine. Some work, some misbehave to various degrees.

Is your programmer genuine? Same caveats apply. STM32CubeIDE does not work well with counterfeit programmers.
