fpga fifo compile error

[Andrew_Quick]

Hi,

I downloaded the RS232 FPGA example program and attempted to make a small modification to it. The original is like this; See attached file 'beforeModification.PNG'

I wanted to read back the amount of data still in the FIFO in case I had not read everything so I changed it to this; See attached file 'withModification.PNG'

The target is 7841R using compiler Xilinx 13.4. It goes wrong in the synthesizing section with the following error message;

Details:
ERROR:HDLCompiler:1566 - "C:\NIFPGA\jobs\K7I4YEj_RQC5mWo\NiFpgaAG_FPGA_Main.vhd" Line 869: Expression has 11 elements ; formal ocountfullcount expects 10

I am running;

LabView 2012 SP1 f3

NI R Series Multifunction RIO 12.1

Am I doing something wrong?

Thanks

Andy

Hi Andy,

Did the example compile properly before you made your modifications?

The RSR232 FPGA example ships for SingleBoard rio targets I'm guessing you've modified the project to suit your Stand Alone multifuction RIO card?

Can you upload the project as a ZIP file?

Regards,

Maciej

Yes it does compile before the change I made. I have zipped up the project and attached it. If you compile 'FPGA Main.vi" it will compile. If you try "FPGA MainError.vi" it shows the problem.

Thank you.

Andy

The problem went away when I copied the source files to a different folder
