FPGA program does work in LabView 8.2 but not in LabView 8.5.

Hi,

I have two compact RIOs (I bought one 4 years ago, and the other last year). I tried to duplicate systems for my experiments. But unfortunately I could not because the error was generated when I complied my function in new compact RIO. Error message is 

" Mapping all equations...
FATAL_ERROR:Xstortability/export/Port_Main.h:127:1.17 - This application has discovered an exceptional condition from which it cannot recover.  Process will terminate. For more information on this error, please consult the Answers Database or open a WebCase with this project attached at http://www.xilinx.com/support.
ERROR:Xflow - Program xst returned error code 1. Aborting flow execution... "

The only different thing between two compact RIOs is that the old one was compiled with Labview 8.2, but the new one was compiled with Labview 8.5. The program which I made does not have any problem with old compact RIO. I attach my problem here. Could you check my program for me?

Here are specs of two systems

Old one is CRIO-9002, which has 9101 (SN#DF5EF9), 9263, 9215, 9472, and 9411.

New one is cRIO-9012, which has 9101 (SN#13A24EF), 9263, 9215, 9472, and 9411.

Did you allready search in the forums for this error?

There are lots of hints on this Xflow errors.

I did, but I could not find it. Could you refer the related one for me?

Good Morning Sung-Jin,

Here are two links which discuss similar errors:

FPGA Compile Failure in Port_Main.h:127:1.16 or Port_Main.h.127:1:17.

Have you looked through your FGPA code since switching versions of LabVIEW?  It is possible that certain features are unavailable or implemented differently in the newer version, which is causing the compile to fail.
