Codewarrior debugging error

[simonh]

While trying to debug some software on a target board codewarrior is now giving me the error "CCSProtocolPlugin : Failed to stop process" when I attempt to break the program, I then have to use kill thread and hence lose all my debug information.  

I am connected to the the target with a parallel port Wiggler, which used to work fine. I have changed wigglers, power supply, and parallel cable with no luck.

This now seems to be a permanent problem, which I can't get around, as far as I can tell the code is not running as no data is output from the unit under test and no breakpoints can be hit.

The version of codewarrior I am using is 5.6.1.1658

The only help I can find on the forum is something to do with earth loops, but as nothing has changed on my set up why has this now occurred?

OK, are you using a laptop or desktop system as the development system? Some laptops have marginal power supplys. When you try to drive a parallel-port wiggler off of just the laptop's battery or its parallel port, there's not enough power to drive the wiggler's signals to the proper levels, and you get flaky operation. I once had a Dell laptop where I had to carry the dock with me because only its parallel port--and not the laptop's--could drive the wiggler reliably.

If it's a dekstop system, has something happened to it? Maybe a big cool LCD screen or other peripheral device was added to it that's drawing down the power?

I am using a desktop, with  no change in any peripherals, I have tried moving to laptop which has codewarrior on it and it seems to work fine now, so I think the problem is with the desktop PC,

thanks for the help
