CCS启动调试点击运行之后，几十秒后连接断开，报错信息如下：
Cortex_M3_0: GEL Output: Memory Map Initialization Complete.
Cortex_M3_0: GEL Output: Board Reset Complete.
CS_DAP_0: Power Failure on Target CPU: (Error -180 @ 0x0) The controller has detected a target power loss. The user must turn-on or connect the power supply for the target. (Emulation package 7.0.48.0)
Cortex_M3_0: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
请问这是什么原因？
