依照helloworld教程，成功通过simulator成功进行了调试，但是尝试通过板载仿真器调试时提示未能正确连接仿真器。save到xds 2xx on board emulator后，点击test connection弹出以下提示：
[Start]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

This error is generated by TI's USCIF driver or utilities.
The value is '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.
The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.

直接launch selected configuration也会报错说未能正确连接。采用的是大端，主板的sw3、5、9全部置为on，usb连在仿真器的miniUSB上。请问如何正确配置仿真器使之正确连接PC并进行调试？
