您好：
我之前买了一块TI原厂的DSP开发板TMDSEVM6657LS，一直都是在仿真进行操作，使用的是从论坛上下载的STK_C6657例程以及在这个基础上修改的程序进行测试，一切正常。
随后在一次测试EMIF接口连接AD的时候，一开始可以正常仿真，然后运行过了一阵，再仿真就不正常了，可以进到仿真界面，但是我的程序，运行到KeyStone_main_PLL_init(100, 10, 1);的时候就不能进行下去了。
下面是我测试时候出错的信息，麻烦工程师帮忙分析一下，这是出了什么问题，谢谢。
在console里面显示的信息是：
[C66xx_0] Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
C66xx_0: Power Failure on Target CPU
C66xx_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
C66xx_1: No Clock Signal On Target CPU
C66xx_1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
这个看起来是PLL失败了的样子。
再之后，我又lanuch了一个之前的ccxml配置文件，connect core0 ，load GEL ，使用的是光盘自带的“evmc6657l.gel”，然后进行Global_Default_Setup，在console里面的信息如下：
C66xx_0: GEL Output: Setup_Memory_Map...

请问这大概是个什么情况？是哪里坏了么？我现在也不知道能够通过测量什么来判断是谁出了问题，会是DSP芯片坏了么？
多谢！！！
