6678le评估板连不上

参考如下link设置EVM，看是否能连上仿真器。

按说明设置的 PC还是检测不到硬件设备 

[Start]

Execute the command:

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

[Result]

This error is generated by TI's USCIF driver or utilities.

The value is '-250' (0xffffff06).

The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.

你使用的是带子卡Blackhawk 560V2仿真器的EVM么，像是硬件连接有问题，没有检测到可用的仿真器连接，需要连接到子卡的mini usb。拍个照看看你的硬件连接。
