Unable to get rid of some automated debugging mode
Oct 13th, 2025 at 7:07pm
Print Post  
I am using version 2.2024.0722.

Once I accidentally clicked the Build and Upload button instead of upload, and since then I am unable to get rid of the debugger starting automatically and also a tool window appearing like "Expression on COMx". 
I don't use the debugger and the tool window is quite intrusive covering other windows.
When I try to connect the serial port monitor the Output automatically switches to Micro DebugTrace and a Launching Debugger message appears.
I tried turning off the debugger at every possible locations in various settings in vain.
Please help me to get rid of this automated debugger mode, it is killing me. Angry

If you select the Release Build configuration this should disable the debugger.

You can force it off in any configuration by setting:
1) vMicro > Debugger > Automatic Software Debugging (Debug/Release) to OFF
2) vMicro > Debugger > Debug set to Off

Thank you Simon for your response, I believe I switched everything off but the problem is still present. Could you please check the screenshots attached?

That looks correct. 

Have you performed a Build and Upload with these settings since changing them?

Once the build and Upload has happened the Serial Debugger should no longer launch post upload, or when opening the Serial Monitor.

Yes I did, let me show what happens, please see the screen capture video attached.
Basically the debugger doesn't give up starting automatically when serial line gets connected.

Thanks for the video and agree something seems off.

Can you enable the below options:
  • vMicro > Compiler > Verbose
  • vMicro > Uploader > Verbose


Then perform a build and Upload and attach the complete output as a text file for us to review?

When upload completes the debugger immediately jumps in, also clearing the log in the output window, so I had to collect the logs  in two separate steps.

Since this issue also the uploaded code does not work, esp can't start anymore.  While there is a slight chance it got corrupted at the same time vMicro went mad, but I think the probability of this is relatively low.

This is what I get in serial monitor:
17:22:44.194 -> 8

Thanks for the logs, and nothing stands out currently and no Debugging code is being injected into the sketch from those logs.

Can you update Visual Micro to the latest release from our downloads page, as the version in use is over a year old, just so we can ensure we are able to debug in the latest version?

I figured out that this behavior is related to project. If I compile and upload another project the issue is gone.  Also the uploaded code starts as expected on the same chip.

As soon as I return the original project the same problem appears again, and the code does not run (which used to run previously).

So can you help me to understand which project settings may influence this ?

Thanks for the update, and yes the settings are stored within the project file.

From your video clip there are multiple projects in the solution, which could be causing some confusion.

First ensure the vMicro > General > "Active Code Has Priority Over Solution Explorer" option is unchecked.

Now set the project you want to disable debugging for as the Startup Project, and check the debug options are set to Off.

Now when building and uploading that project it should work as expected.

Unfortunately this does not solve the problem, the debugger always jumps in when the serial port gets connected.
