FPGA couldn't stack the data on FIFO working on cRIO-9082 and NI 9223 module

Hi all !

I made below logic working on FPGA ( chassis : cRIO 9082 /  Analog input module : NI 9223 )

* These logic is for analyzing automotive engine combustion.

As title, it ain't work well.

Is there a basic mistake or any problem...?!

That makes me crazy. 

Thanks for reading it anyway!

What does "ain't work well" mean?  (PS.  Ain't ain't a word.)

What is it doing wrong?  What is it not doing right?  Are you getting error messages?

[Sungmoonlee]

Sorry for the grammar 😞

Any signal from FPGA is not transferred to RT.

Building process has no problem and logic seems to be okay..........

No error message!

Nothing jumps out at me at the code from the FPGA that you are showing.

But where is the code that is running on the realtime controller?  Maybe the problem is there.

Thanks for your kind attention!!

I solved the problem. IRQ was the matter. Interrupt logic between RT and FPGA got tangled.

After deleting IRQ sequence, problem solved!!
