I am using STM32CubeIDE V1.11.0
I have exactly the same issue which was described in this post:
https://community.st.com/t5/stm32-mcus-boards-and-hardware/st-link-gdb-server-issues/m-p/64010#M623
Multiple weeks everything works fine. But suddenly it stops working and i always get this error message when I try to Debug my code in CubeIDE:
Failed to bind to port 61235, error code -1: No error
Failure starting SWV server on TCP port: 61235
Failed to bind to port 61234, error code -1: No error
Failure starting GDB server: TCP port 61234 not available.
Shutting down...
Exit.
I tried multiple things:
- Shuting down PC completely (and disconnect from power supply) and booting again multiple times - it didn't change anything
- I changed the Port in the Settings to 61238 - same error message, but with the 61238 port number
- I changed the ST-Link Device - same error message
- I connected the ST-Link to an other board with an other controller (and selected the appropriate project in cube) but get the same error - so this error seems to be independent of the selected project and Microcontroller.
- I tryed to connect to the target with STM32CubeProgrammer. This works. I can read out the Flash and I did a full chip erase. Than I changed back to the CubeIDE and tryed again to download and debug - but I get the same error message again.
I enabled the "log file" option in the debugger settings. This file says:
COM frequency = 4000 kHz

What does it mean with "Device in lock up state"? There are no lock fuses set in the target. And the CubeProgrammer can read and write the target without any problems.
I am completly stucked with this problem. And everything I read in the Internet about this error does not helped. Maybe some one here can help me?
