Hello @Mahmoud Ben Romdhane 

I would like to share the project file for further analysis as suggested. However, I prefer to share it through a private channel instead of publicly.

Could you please let me know the preferred private method to share the file securely?

Thank You

Hello @Badrinathan ,

I suggest that you upgrade your Debugger ST-LINK to V3 version.

Before programming, I recommend also that you do a full chip erase with STM32CubeProgrammer.

Thanks.

Hello @Mahmoud Ben Romdhane @stforum 

Thank you for your response.

I have performed a full chip erase using STM32CubeProgrammer, and I have also upgraded my debugger from ST-LINK V2 to ST-LINK V3. Currently, I am using ST-LINK V3 for debugging.

After this upgrade, the "No target found" error is not appearing consistently anymore. However, it still occurs intermittently. When the error appears, I perform a full chip erase again, and the issue temporarily disappears. But after some time, it reoccurs.

Could you please guide me on how to resolve this issue permanently?

Also, I would appreciate it if you could explain the main differences between ST-LINK V2 and ST-LINK V3.

Environment Details

1. Microcontroller: STM32U535CBTX
2. Debugger: ST-LINK V3
3. STM32CubeIDE: v1.17.0
4. Operating System: Windows

Thank you,
