    Unreliable debugging connection

    fabrizio.bertocci

       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

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

             

          pins like XRES, supply rails, GPIO, etc.
