调试连接不稳定

我有一个冰块连接到CY3174（CPU：CY8CPLC20）通过RJ45连接器。
不幸的是，我发现调试器非常不稳定。
在一台机器上（运行虚拟机内的WindowsXP），PSoC Designer根本就不超过下载：在我把图像下载到板上之后，它说“准备运行……”并且永远这样。
我尝试了另一台机器（Windows 7），我在这里得到了更好的东西。我让电脑停在：
JMP启动
下载图像后。
不幸的是，调试程序偶尔会跳回到那个位置（0x000）…
在几次重置之后，只有几次，我管理了PC，以击中我的断点之一（这是简单的主线之后的几行），但任何尝试一步，设法回到0x000。
你知道为什么吗？有什么建议吗？
注：
-我使用PSoC设计器5.3，所有新安装的工具（在这个新的Windows 7机器中）。
-我不使用看门狗，只是一个简单的项目从PSoC设计器7从头开始创建
任何帮助/想法是赞赏！

   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!
