FIFO.config -61206: but the name of FIFO exists

[cderrico]

Hallo,

I'm relative new to cRIO and I became an error from last time I compiled my FPGA.

HW Description

• cRIO-9035
• 4 x NI9229

Software Description

• FPGA: I have 15 DMA FIFO (I can make this according to this document), that send asynchronous messages on each FIFO   (show attached Picture)
• RT: I catch this messages and I store them in a TDMS file

Problem

• FIFO.Configure or FIFO.start give me "Error -61206". This Error, as shown here, means that the name of this FIFO doesn't exists. But as shown in picture it exists. I don't know what's happened. Is the first time that I become an error like this.

For your kindful help, I will say you "Grazie!"

I found the problem.

Only the FIFOs really used on FPGA can be configured.

If you declare a FIFO and you will not use it on FPGA (for example in order to make a test of only a part of your project) you have to remove from RT code the parts where you configures, starts ancd closes the FIFO.

Thank your for your attention.
