CCS6.1.3安装后，刚开始用是正常的，今天突然开始在调试程序过程中不断的断开连接，信息提示如下：
C66xx_24: JTAG Communication Error: (Error -2172 @ 0x0) Unable to communicate with the debug probe. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.222.0)
不断电再次连接时，连接无法成功，报错如下：
IcePick_D: Error connecting to the target: (Error -2172 @ 0xD) Unable to communicate with the debug probe. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.222.0)
请问，这种现象是什么原因？
