我在CCS 5.5中使用Blackhawk USB560 Emulator仿真题对F28335进行程序下载，当仿真器、开发板、笔记本三者连接后，笔记本设备管理器中出现仿真驱动标志，见下图。
显示连接正常，但是我在CCS 5.5软件中进行程序下载时，显示连接不正常，ccxml仿真文件Test Connection中显示如下。
[Start]
Execute the command:
%ccs_base%/common/uscif/dbgjtag.exe -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity
[Result]
-----[Print the board config pathname(s)]------------------------------------

-----[Print the reset-command software log-file]-----------------------------
This utility has selected a 560/2xx-class product.
This utility will load the program 'bh560usb.out'.
The library build date was 'Aug 20 2013'.
The library build time was '23:04:59'.
The library package version is '5.1.232.0'.
The library component version is '35.34.40.0'.
The controller does use a programmable FPGA.
The old VHDL code has a version number of '386336272' (0x17070610).
The new VHDL code has a version number of '386336272' (0x17070610).
An error occurred while hard opening the controller.
-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver or utilities.
The value is '-180' (0xffffff4c).
The title is 'SC_ERR_CTL_NO_TRG_POWER'.
The explanation is:
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.
[End]
我想请问一下是什么原因造成的，该怎么解决？有没有知道了
