CW10.x freezes on debugger-launch

WadeH — Mon, 10 Nov 2014 18:45:44 GMT

I've been using CW10.5 for three weeks, and have used it on both 9S08 and MCFMM256 projects. Everything went well until yesterday, when the 'debugger-launch' froze with no explanation.

Looking at the 'progress' tab shows this:

Unless one looks at the 'progress'-tab, it's not obvious what;s going on, and any number of launches can be attempted, each one leaving a 'Loading symbolic information' operation that can only be deleted by closing CW.

That "40%" occasionally gets as high as 60%, but never finishes. And clicking the red button does not affect the results, except to note that 'Cancel Requested.' No cancellation occurs

- Working with TWR-MCF51MM demo-board, using on-board OSBDM

- Windows 7, 64-bit

- Re-installed 10.5 with no change

- Installed 10.6 ditto

Does anyone have an idea on this?

Maybe talkin' to myself, but...

The problem appears to be slow-motion response from the debugger. The 'eternal symbol load' described above will complete, but takes at least fifteen minutes.

More: clicking the 'pause execution' button takes about a minute to happen (this was always the case.).

After a pause, the 'CPU Registers' window, as an example, is populated at about one value every five seconds: this used to be nearly instant.

Editing, re-compiling and reflashing the device has a turnaround time of minimum twenty minutes:

That's definitely not normal. Can you check if you Zombie tasks running, see http://mcuoneclipse.com/2012/06/01/killing-me-softly-zombies-and-debugger-engines/

How much RAM does your Windows system have?

Thanks for the response.

Your explanation of zombie-processes makes sense, and I had already checked Task Manager several times looking for suspects: at one time there were two running copies of DE.exe, but only once, of a dozen or so instances.

It still sits at "Loading symbolic information: 40%" for a reliable 20 minutes. What exactly is going on in that operation?

I have 8GB of memory and have turned off all the big consumers ( big apps, multiple .pdf's etc.)

... and now it doesn't. "All I did was®" add a table of 12-bit values for sin(x) to the source and the problem vanished. It works as before and I can't make it fail (not that I tried too hard.)

I couldn't really call this one 'answered,' but I am done with it.
