调试6672时出现(Error -1143 @ 0x0) Device core was hung错误

自己做的板子，CPU为DSP-TMS320C6672

在CC5下，仿真器是SEED-XDC560V2Plus，用JTAG在CCS下的test connection没有问题，但是当下载程序时，老出现错误，错误信息如下：

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)

请问专家这个现象可能是哪儿的问题？需要从哪儿下手解决。
