自己做的板子，CPU为DSP-TMS320C6678 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 5.1.73.0)
电源测试输出正常稳定，所需时钟均正常，DSP输出的测试时钟也对。 复位状态已经结束
请问可能是哪儿的问题？需要从哪儿下手解决。
