请教关于CCS5.5 连接 仿真器 SEED XD560的问题

似乎 仿真器驱动是安装好了 但是connect后 如下


An error occurred while soft 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 '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.
The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.
[End]

求解答 谢谢
