Error 61496

Hello,

the following error occurs when trying to compile a FPGA VI in Labview 2012:

An internal software error has occurred. Please contact National Instruments technical support at ni.com/support with the following information:

Fehler -61496 bei

Mögliche Ursachen:

LabVIEW FPGA: Im LabVIEW FPGA Module trat ein interner Fehler auf. Wenden Sie sich über ni.com/support unter Angabe folgender Informationen an den technischen Support von National Instruments:

Es wurde ein unerwarteter Case erreicht.

Case Selector Value:

It only appears when using signals (ADC, SPI), which are marked as "internal only" in connection with a CLIP.

How can one readout the ADC using a CLIP? Labview does not interpret the signals in the vhd-file as physical signals. We connected them in the VI with the corresponding ones and it worked fine except for SPI/SCK, SPI/SDO and ADC/AD_CONV.

Thanks a lot.

Hi,

have you tried to solve the problem with the following link?

Advanced Code Generation Page (FPGA IO Properties Dialog Box) - LabVIEW 2012 FPGA Module Help - National Instruments

Best regards,

Thanks a lot for your reply.

It didn't solve our problem, though.

What _did_ solve it in the end was assigning different names to the variables in the VHD file.

We previously had variable names like "SDO", which is the same name as the signal.

Strangely having the same name is no problem when dealing with signals which are not marked "internal-only".
