Dear STMicroelectronics Support Team,
I am writing to report a persistent issue with STM32CubeIDE that is affecting multiple users in our company and blocking our development work.
Issue Description:
When we try to debug any STM32 project, the debugger launch process gets stuck at 51% with the message:
Launching: Initializing debugger services
The issue occurs with different versions of STM32CubeIDE and with multiple target boards.
Steps to Reproduce:
Open STM32CubeIDE and build the project (build succeeds).
Click Debug.
Debugger launch stops at 51% and does not proceed further.
Environment Details:
STM32CubeIDE Versions Tested: 1.9.0 and 1.13.2 (same result)
Operating System: [Windows 10 / Windows 11]
Target Boards Tested:
STM32F429I-DISC1
STM32F407-DISC
ST-LINK Firmware: [if known, mention version]
Actions Taken:
Reinstalled STM32CubeIDE (both versions).
Reinstalled ST-LINK USB drivers.
Verified ST-LINK is detected correctly in Device Manager.
Tried on multiple PCs within our company — all systems show the same behavior.
Despite these actions, the issue persists on all systems and boards.
I have attached a screenshot of the IDE progress bar stuck at 51% for reference.
Could you please investigate this issue and suggest a solution or provide a patch/update if this is a known problem?
This issue is affecting multiple developers in our company, so an urgent resolution would be greatly appreciated.
@Souhaib MAZHOUD I have the same issue. My project is for a NUCLEO-H7S3L8, using an external memory loader to load the application into external FLASH, and bootloader in internal flash. Based off the ethernet projects here . We have been programming and testing this code for months, and then all of a sudden I was unable to debug today.
One thought that may not have been addressed in this thread is that the port to talk to GDB may be blocked. However, I don't see the `arm-none-eabi-gdb` executable running at all. Or perhaps local antivirus software is preventing it from running?
Unfortunately, this means my project is dead in the water until we can resolve this. Please escalate, if possible.
Here is a co-worker's build output, which is "good":
Here is MY build output that is "bad". I cannot get the "terminated with code -1" to go away:
I disabled parallel build, but exit code -1 still occurs, see below. Any other ideas? I'm running STM32CubeIDE version 2.0.0. Perhaps I'll go back to 1.18 or 1.16
Ah, so that is launch of the debugger, not of the IDE.
As a quick workaround, disable automatic build on launch. Of course, verify that the project has been built successfully and the specified elf file exists.
Very good ideas. I tried creating an IOC and project in my user directories, but it's still doing the same thing. Here's a screenshot of the permissions for my user directory:
I tried a few times in different subdirectories of my user directory. It's possible that it could be related to security protections on this PC.
