LabVIEW TI DSP的溝通問題

我利用NI所提供與TI DSP溝通的範例,2004-10-28_100607_Filter.exe

當我在執行時發生一些錯誤訊息如下

Error 7 occurred at File/Directory Info in CCS Download Code.vi->Filter_dsk6x11.vi

Possible reason(s):

LabVIEW:  File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on UNIX.

NI-488:  Non-existent board.

請問這是什麼問題呢?

請有經驗的人回答一下吧,謝謝
