crio 9014, 9233

[Pencimen]

Hi,

I've got a cRIO 9014 with five 9233 modules and I'm just trying to run a simple data logging program.  I've constructed target and host vis based on NI example programs including the embedded data logger program and a sychronizing 9233 modules program. 

I'm getting a -50400 error (transfer did not complete within timout period etc.)   I imagine I'm just doing something stupid, but I'll be damned if I can figure out what it is.

The code is enclosed.  I'm using 8.5 on an xp.

"The code is enclosed." ... Ahhh...No it isn't.

Hi Doug,

Are you using DMA FIFOs?  If so, are they configured as Target to Host or Host to Target?  If you change the timeout to -1 (never timeout) is the data read correctly?

Hi Jennifer,

I'm configured target to host.  I tried -1 in both the read and write without success.  I'm just trying to run the example program in chapter 8 of the cRIO Fundamentals course manual.  The target is the same as the one on Figure 8-36 DMA FPGA with FIFO VI Block Diagram and the host is as shown in Figure 8-38.  I'm getting the first read at the host, then nothing after that.  The target is giving me a 65538 error.

Something is blocking me from enclosing attachments; that's why I haven't forwarded the VIs.

Thanks for the help,

Doug

Hi Doug,

Besides changing the timeouts to -1, did you modify the example code in any other way?  If you do not use FIFOs, does the code run as expected?
