Read/Write to FPGA help

Hello, I am using NI Digital Electronics FPGA Board and LabVIEW 2009 software. I made a simple vi that uses the Memory Write method to write a single data on the memory of the FPGA. However, whenever I use the Memory Read method, the compilation aborts past halfway and shows this message:


This application has requested the Runtime to terminate it an unusual way

Please contact the application's support team for more information.

ERROR:Xflow - Program par returned error code 3. Aborting flow execution ...


On the other hand, I'm quite a newbie in using the FPGA Memory Read/Write method, and it seems that example VIs on the internet regarding this is scarce. I suppose that this problem arose because something is wrong with my use of Memory Read/Write method... What can you suggest?

Hi Paul, 

The only other time I've seen this error it happened because one of the vi's that were being used was corrupted.  I would suggest trying to copy and paste all your code into a new vi and save it. 

This should resolve your error. 


Let me know how this turns out,

Hi Dave, I've already fixed the problem by implementing the Memory as a look-up table rather than a block memory.. anyway thanks for your help 🙂
