经过这几天的测试发现，DM37x EVM开发板提供的WINCE、LINUX及Android三个操作系统均存在死机的情况。
测试都是利用开发板提供的SD卡将系统启动，之后运行TI的官方测试程序，长时间运行，情况比较糟糕，经过一夜的运行，早晨到单位看，都死机了。
不知道是买的开发板硬件有问题，还是各个系统软件有问题。
在PB中增加KITL调试后，出现以下的调试信息后就死机了
PB Debugger The Kernel Debugger is waiting to connect with target.
PB Debugger The Kernel Debugger has been disconnected successfully.
