Cannot debug with STM32CubeIDE and ST-LINK/V2, but CubeProgrammer works.

[LOrozco]

I am using STM32CubeIDE version 1.13.2 and an ST-LINK/V2.

I have a custom board with an STM32G031CU86 and I am connecting via SWD.

When I try to either Run or Debug from the IDE, I get an error from the ST-LINK (see below).  However, using the STM32CubeProgrammer, I can connect to the ST-LINK, load up the .elf file and program the board just fine.

This makes me think the board and programmer are working correctly, but I'm missing a setting somewhere to make this work.  Based on the errors below, it sure smells like a Windows firewall issue, but I can't find anything blocking anything called 'gdb' or 'stlink'.  Any ideas?

The Error Message:

Failed to execute MI Command:
target remote localhost:61234

Error message from debugger back end:
localhost:61234: Connection timed out

The following is the console output:

I'm also attaching my debug configuration in case it helps.

Counterfeit programmers don't work with the newer releases of STM32CubeIDE (but still work with STM32CubeProgrammer). Genuine programmers should work okay.

Does it work with a new project generated from CubeMX?

[LOrozco]

Is there a way to tell if I have a counterfeit programmer?  This thing has the ST logo on the front and an ST-branded label on the back with a serial number and all of the compliance agency marks, etc.  Seems like a lot of effort for a $50 programmer (but I guess I've seen worse...)

In case this means anything, the serial number on the label is B 2018 41

Also,

* This project was started with CubeMx (just a blinky light and all of the peripheral configuration functions generated by CubeMx at the moment)

* I disabled all of the Windows Defender firewall settings (Domain Network/Private Network/Public Network) and it still didn't work...

There's no perfect test, but if it looks like this one and you bought it from a reputable seller, it's probably real:

As opposed to the "ST-LINK V2" or "ST Link V2" ones on amazon with the 10-pin header which are all counterfeit to some degree.

That would have been my next guess. Could still be the reason if there's a setting you missed somewhere, or some other program at work, but I'm kind of grasping at straws at this point. I'll post again if I think of something else.

Thanks for the help.  My programmer looks genuine and came from Mouser, so I'm guessing that is not the problem.

Also, I apparently hit 'solution' with my clumsy trackpad so your previous comment looks like the solution...oops...

I would also guess Mouser sent you a genuine programmer and something else is afoot.
