NI USRP 2943R - compatibility problems with LabVIEW 2015

Hi all,

I'm working on LabVIEW 2015 and NI USRP 2943R. I connected the device via 1G Ethernet.

I used the NI-USRP Configuration Utility for updating the FPGA image to "usrp_x310_fpga_HGS.lvbitx". Now I wanted to run some examples.

First, the example "niUSRP EX Rx Multiple Inputs (Single Device, Multi Channel).vi" works fine for lower IQ rates (up to 3MSa/s @fc=2GHz) (btw: Where could be the problem? I believe the error was regarding to Fetch RX Block)

But unfortunately, the transmitter examples e.g. "niUSRP EX Tx Multiple Outputs (Single Device, Multi Channel).vi" don't work. I get a RuntimeError ("-1074118627") "Expected FPGA compatibility number 13, but got 19."

Then I follow the advice of the error message --> I update the FPGA image manually by command window (uhd_image_loader --args="type=x300,addr=192.168.10.xxx") But after the successful update, I updated to compatibility number 33 and it also doesn't work (same RuntimeError)

 

Do you have any hints about my problem?

 

Thanks, Andreas.

Why does a newer image version (compatibility number 19 or 33) not work on an NI-example which requires version number 13?
