Problems debugging ChipworkX with VS2010


Not really specific for this forum perhaps,
but still I’m hoping there are others who’ve had this

Been working on something for some time, without any problems,
now lately whenever I start or stop a debug session with the ChipworkX it takes ages for VS2010 to respond (usually ends up in a white overlay … not responding)…

Any suggestions?
It’s really annoying to debug something like this.


Do you have any extensions to VS installed? I would disable any extensions/add-ons. The only other thing I can think of is if you have a tight loop like:

    //do nothing

Stuff like that can make it hard for the debugger to attach as the processor is completely tied up.


Well I definatly do not have a loop and the blocking is before the app is even run.

As for addons, the only one I have is devexpress,
although I did not have any probs with it in the past,
I’ll try to disable it.


Disabling all add-ons (resharper being the only one)
did not help at all.

As for the loop.
After the application finally starts,
let’s say I put a breakpoint on:

if (!Directory.Exists(path))

And then terminate execution it takes up to 5 minutes for VS2010
to respond again. Even disconnecting the hardware does not help.


The only other test I can think of is to load a very simple program on the board and see if the symptoms remain.


As I expected, a new project boots and stops in no time
Now, even if I remove all the code from the Main in the other project, the problem persists.

Come to think about it, it’s not the first time it happened.
Last time I had to create a new solution, create new projects in the solution and copy all files from the old solution.

It’s clearly something in VS2010 that gets f* up…

But it’s hard to imagine I’m the only one with this problem.


Are you using new beta firmware?


I’ve been working on this project for a while,
have not updated any components on the development system either.

As this is not a project I can ‘fool around’ with :stuck_out_tongue:
It just started… (just like it did in the past) It’s like something gets poluted.

Cleaning the build, removing the .user files, removing the bin / obj folders, nothing helps…


I should also note,
when switching the project from USB/ChipworkX to the Emulator,
vs2010 has no problem starting/stopping the application.

As soon as you use the ChipworkX again it’s game over.


Ignore that last message.
While starting the app is faster, stopping the app while running in the emulator still causes vs2010 to freeze


Eventually I created a new solution for every project,
this way when VS decides to f*** things up again the damage will be limited
(as this has happened before, and will probably happen again)

Now the same code, starts/stops in no time


Can you run a diff on the .sln for the working and non-working to see what has changed?


Just had the same for a Panda project… just stopped working,
didn’t even close VS2010 between the time it worked and the time it stopped.

And we’ve tried many panda II devices…

Output Windows:

Error: a3000000

Waiting for debug commands...

The program '[0x1] Micro Framework application: Managed' has exited with code 0 (0x0).


And here’s a nice kicker…

I reverted the entire solution to a revision from a day before,
and still the deployment is broken… clearly I’m going WTF right now


Did you try cleaning out your bin & obj directories? This could end up being one of those case where only recreating the solution fixes it…


@ ianlee74 You’re a life saver :slight_smile:

The bin and obj directories are ignored by mercurial so they weren’t reverted.
The “Clean Solution” option in VS2010 doesn’t do a good job

Before I did indeed fix solution by recreating them,
but we have projects that contain like a hundred source files and lots of directories

You saved me quite some time, thnx!


Glad I could help. :wink:
