有没有用过TI的TMS320c6672的，我现在Trace仿真器连接不上，JTAG可以连接上，JTAG连接上后，在下载程序时，显示如下：
C66xx_0: Error connecting to the target: (Error -1143 @ 0x0) Device core was hung. The debugger has forced the device to a ready state and  recovered debug control, but your application's state is now corrupt. You should have limited access to memory and registers, but you may need  to reset the device to debug further. (Emulation package 5.0.569.0)
