C6678初始化PLL不成功，报错Trouble Reading PC Register:Device Core is Hung

我用的板子是是C6678的开发板，在初始化PLL的程序里，当运行到PLL_SECCTL = 0x00080000这一句时报错，提示Trouble Reading PC Register:Device Core is Hung.Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings(e.g.lower TCLK).

然后我按照提示使用了lower TCLK，还是报错，提示Trouble Reading PC Register:Device is not responding to the request. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings(e.g.lower TCLK).

我是一只小白，真的没有任何解决问题的思路啊！求指导！谢谢！

建议使用mcsdk中自带的gel或者论坛首页STK进行PLL初始化。
