Read data failed when using FPGA Read and Memory

[lindajiang620]

Hello All,

I am trying the following tutorial to generate the arbitrary waveform with Compact RIO 9074 and NI 9264.

Buggs come when I run the host VI. It doesn't read my mesearement file. Thus the data could not be  writen to FPGA memory. 

The error input of loading the data is like the this:

I don't have any idea how to revise the program. Do you have any suggestions? I appreciate your help.

Error code 7 is "File Not Found", so most likely there is an issue with the path to the data file. If you right-click on the error in control you can select Explain Error and it will give you more details.

Thank you for the remind. I used the same data file in the example project.

However, whenever I ask for a stop in the host VI, the windows will give an error like this.

如果LabVIEW自动关闭为与CompactRIO系统的FPGA背板进行通信而创建的VISA会话，那么该错误就会发生。为防止该错误，您可以打开工具 » 选项 对话框，选择环境类别，然后取消选择自动关闭VISA会话句柄。

如果上述步骤不能解决该问题，使用文本编辑器（例如Notepad）打开位于LabVIEW安装路径下得LabVIEW.ini文件。如果您看到语句cleanupVisa=True，将其改为cleanupVisa=False。如果该语句不存在，则在INI文件最后添加cleanupVisa=False语句，保存，然后重新打开LabVIEW。
