你好！今天使用6678EVM的时候突然评估板自带的仿真器无法与PC进行连接。初步认为电脑的驱动等都没有问题，问题最有可能是XDS560v2仿真器。
整个评估板通电后，XDS560v2仿真器上的LED灯：D2（黄色），D3（绿色），一段时间后只有D3（绿色，不断闪烁）。使用CCSv5的Test Connect进行测试，显示无法找到仿真器。信息如下：
[Start]

%ccs_base%/common/uscif/dbgjtag.exe -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

-----[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]
请问这样的问题该如何解决，查找了许多方法，都没有效果。是不是仿真器的硬件出了问题？
另外麻烦告知一下TI 6678的售后技术服务维修该怎么弄。
