VisualGDB stopped working

[bernardofca]

I have used VisualGDB successfully on multiple projects and it suddenly stopped working.

gdb complains about:

–gdb-set disassembly-flavor intel (I don’t think that this is the issue)

and hangs on:

target remote :59325

I have verified that:

1.  I have the last version of everything
2. OpenOCD test is working OK
3. I have the same problem with a simple new solution (blink LED)

I am using VS2010, STM32F103 and ST-LINK V2

It is likely trivial but I did not solve it yet!

Here is the Log:

Hi,

Please check the OpenOCD window for errors. There was a bug in our recent OpenOCD release that could have caused it and it was fixed in VisualGDB 5.1r6.

Please upgrade to that version or alternatively re-download the latest OpenOCD debug package via Embedded Tools Manager. Then open the Debug Settings page, change any setting there and press “OK”. This should fix the problem.

[bernardofca]

Thanks for the weekend support. I tried all the suggestions and it still does not work.

I tried to re-install everything on a virgin PC and it worked (used the trial version of VisualGDB).

 

Something is obviously corrupted on my PC but I don’t know what. I tried to transfer the working solution and it still fails.

 

What else should I try?

 

[bernardofca]

Additional information: my setup works with the Texane debugger but not with OpenOCD. I have erased and downloaded Open OCD multiple times w/o success.

OK, then please post the contents of the OpenOCD window in Visual Studio here so that we could help you figure out what is causing the problems.

hi, try to iniciate your IDE with adminstrator permission: right click on ide’s icon > execute with adminstrator (or somethinhg like that).

 

[bernardofca]

All: thanks for the support.

In the process of trying everything, I removed VisualGDB, erased all the registry entries containing the magic word, erase all directories, etc

After yet another reboot, I got it back!

I am willing to forget the 2 days of work I lost, if I know how to quickly reverse this situation if it happens again!

[support]

Most likely while deleting and reinstalling everything you installed the new version of the debug package that includes the fix as we suggested above.

Now that you have the latest version installed, the problem should not occur anymore.
