自己做的板子，CPU为DSP-TMS320C6655，之前调试都很正常，boot采用的NAND FLASH EMIF总线启动，该调试板一直都工作正常，国庆后在CC5.2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)
后来检查了电源和时钟都是正确的，SYSCLK输出的6分频时钟也正确，采用no boot方式后，错误变成了Error -1144，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。 |
