Unreliable debugging connection

 I've an ICE CUBE connected to the CY3274 (CPU: CY8CPLC20) through the RJ45 connector.

   

Unfortunately I'm finding the debugger very unstable. 

   

On one machine (running Windows XP inside a virtual machine), PSoC Designer simply doesn't go beyond the download: after I download the image to the board, it says "Preparing to run..." and stays like that forever.

   

I tried on another machine (Windows 7) and I got something better here. I got the PC to stop at the:

   

    jmp __Start

   

after downloading the image.

   

Unfortunately the debugger appear to jump back to that location (0x0000) once in a while...

   

Only few times after several resets I managed the PC to hit one of my breakpoint (that were simply few lines after main), but any attempt to do a step, managed to go back to 0x0000.

   

Any idea why? Any suggestions?

   

Note:

   

- I'm using PSoC Designer 5.3 with all the tools freshly installed (in this new Windows 7 machine).

   

- I'm not using watchdog, just a simple project created from scratch from PSoC Designer 7

   

Any help/idea is appreciated!

If you have done all the obvious things, like noise suppression,

   

good bypassing (polymer tanatalums best for bulk), then consider

   

filing a tech case at -

Re noise, use DSO on infinite persistence and look at supply rails and

   

pins like XRES, supply rails, GPIO, etc.
