刚买了两块 TCIEVMK2LX 开发板，1周过去了，程序都还没有下进去。
现象是这样的：
[Start: Texas Instruments XDS2xx USB Debug Probe_0]
Execute the command:
%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity
[Result]
-----[Print the board config pathname(s)]------------------------------------
C:\Users\jm433\AppData\Local\TEXASI~1\CCS\
ti\0\0\BrdDat\testBoard.dat
-----[Print the reset-command software log-file]-----------------------------
This utility has selected a 560/2xx-class product.
This utility will load the program 'xds2xxu.out'.
E_RPCENV_IO_ERROR(-6) No connection: DTC_IO_Open::dtc_io
Failed to open i/o connection (xds2xxu:0)
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 debug probe via USCIF ECOM has failed.
[End: Texas Instruments XDS2xx USB Debug Probe_0]
