FPGA Compile Error

[Kolibri]

Hi,

sorry, I'm new to this forum and I didn't find a subforum for LabVIEW FPGA - so I'll just post my question here.

I have some sort of experience with LabVIEW applications running on a desktop PC or applications that are downloaded onto microprocessing boards. However, I have a new project that involves the use of different platforms at once (host pc, real-time engine and FPGA), which I'm new to. Now, it's also the first time I'm working with LabVIEW FPGA, and here's my question concerning the compiling of a LabVIEW FPGA project.

To start with, I created a new project, added my targets (as above: in addition to a host pc, I'm gonna use a real-time desktop and an FPGA which is connected to the real-time machine), added FIFOs and In-/Outputs which I'm gonna use with the FPGA and then simply copied four VIs that a colleague of mine once created for the same FPGA hardware (they make use of those FIFOs and the In-/Outputs I added before. These VIs should simply implement the EnDAT-protocol (the sensors connected to the FPGA will use this).

Now, when compiling the main VI on the FPGA (wether I compile it on the FPGA or on the host pc with simulated I/O - either way) the compiler goes through "Creating Intermediate Files" Stages 1-5 alright and then either aborts during or after stage 6 and displays the following error message:

------------------------ 

Error -64997 occurred at EIOResourceTree_Provider_ReportMissingRequiredTagError.vi

 

Possible reason(s):

 

LabVIEW Elemental IO:  An internal software error in LabVIEW Elemental I/O component has occurred.  Please contact National Instruments technical support at ni.com/support with following information:

 

Required tag was not found in the resource file.

 Provider name: {F1B2FBB4-18BD-4496-8387-994D4E728C6E}

Tag: DcmSpecs/virtex2/-4/LowFrequencyMode/CLKOUT_FREQ_1X_Min

-------------------------------

I've researched the LabVIEW and the NI Developper Zone for hours now, I simply can't find anything concerning this matter.

I'd really appreciate any help whatsoever...

Thanks a lot,

David

Hi Kolibri,

What version of LabVIEW FPGA and what modules are you using? With LabVIEW 8.6 this has been filed as a corrective action request.

Hi Ipshita,

thanks a lot for your message.

Indeed I'm using LabVIEW 8.6 and apart from the FPGA module I also use features of the RT module.

First it's good to know, that this problem seems to be known. But what exactly does "been filed as a corrective action request" mean? Is there any link where I can find additional info on this?

Thanks again,

David

Hi David,

Filed as a 'corrective action request' means it has been targteted to fix in the next version. The number for this request is 109747 and it's status has been set to "Closed" as it could not be reproduced. The way to find information on these requests is to go to this page and try to get support from National Instruments. In your case I would try to repair the FPGA module and RT and see if that makes a difference.

Hi Ipshita,

thanks again for your help.

I ended up installing LabVIEW 8.6.1 and updated the modules (FPGA, RT) as well. So far, the problem didn't occur again, so let's just knock on wood...
