LabVIEW FPGA: The configured item does not exist.

[zundap1970]

Hi all,

I'm modifing a FPGA VI on my cRIO to expand an old project with additional AO.

On my FPGA VI, under FPGA target in my project, I added a data structure (typedef) with the list of control driven by RT enviroment.

Now :

1) I built the fpga bitfile without error

2) In RT I open the fpga reference and put it  in into "Read\Write FPGA control"

3) In "Read\Write FPGA control" I'm able to select the added FPGA control with  right click and select "Control" submenu. It mean that the FPGA is correctly build and pointed, right?

4) When I run I get the error from "Read\Write FPGA control" :

 Error code : -61206 Possible reason(s)  : LabVIEW FPGA: The configured item does not exist.

I tryed to use, for test, old controls (in the project since previous delivery) and they work

I'm making a mistake in my custom control definition, but I don't understand.

Suggestions?

Hi,

in my opinion the issue is related to the usage of Read/Write control function associated to a typedef. Can I ask you the reason why you created a typedef?

Hi Alamanna,

you're right, there was a mismatch between the typedef and the bitfile.

I don't know the reason to use the typedf, I'm updating an existing project, maybe the reason is due to LVOO approach and the choice to organize the data structure and informazion inside the class cluster

Thanks
