NI-RIO driver crashed

[prof.maio@gmail.com]

Hi to all,

I'm using FPGA Interface C API Generator 15.0 for my C++ application.

Sometimes I get the error mentioned in the attachment.

Do you have any idea?

Thanks in advance

To  show us an Error without providing the Context (like "What were you doing when the Error occurred?", or "Why do you think it only occurs sometimes?" or "Show us the code you are trying to run", or "What is the code supposed to be doing?" or "What resources are being used?", or "What version(s) of the Software are you using?"), I would say that you have an "occasional error".  Have you reported the Error to NI?  It looks like it may be a failure in one of their underlying support/run time/code generation routines (can't tell which to suspect, as we don't know the context), and if they've seen this before, they may have a work-around.

Dear Bob,

Here's more details about the context.

We use 4 NI PXIe-7971R, 1 NI PXIe-7975R, and a SMBus Controller with drivers in version 15.5.0.49152.

The FPGAs are driven by a C++ application, the whole being hosted on a Windows Server 2012 R2?

The problem we are reporting occurs on the NI PXIe-7975R FPGA while running a bitfile implementing parallel processing on 3 different channels.

We have no problem when we process on one of the 3 channels, but the Windows server crashes after a few minutes when we process on several channels at the same time.

The NI Update Service on the Windows server suggests to install the following updates but we are not sure if it's necessary, and if it won't lead us to any compatibility issue with our bitfiles.

Dear Giovanni,

     Am I correct that everything is running on a PC running Windows Server 2012 R2?  What version of LabVIEW are you running?  [I'm guessing it is 2015, since you mention Drivers that seem to be from that Version].  Are you running 32-bit LabVIEW (on a 64-bit OS, of course) or 64-bit LabVIEW?  I don't know all of the NI hardware to which you refer -- can you give me a brief description of all of the "boxes" and major NI Software Components you are using?  [I'm trying to understand if you are running LabVIEW Real-Time, with the Host being Windows Server and the Remote(s?) being PXI boxes].

     If things are working (and they are not, it sounds like),  you can consider updating, but I would urge caution in applying updates that either (a) are for versions newer than what you are running, (b) for hardware or software components you do not have installed, or (c) for 64-bit components if you are running 32-bit LabVIEW.

I'm using 32-bit Labview 2015. it is useless to say that the 64-bit Labview 2015 is not stable enough as a fpga development environment. I use labview only to compile the bitfiles. The application is written in C ++ and uses the APIs created by the generator. The system is typical, data entry on DMA, processing on FPGA and reading of data from DMA.

Thanks
