Re: [Discuss-gnuradio] Getting "Environment Error" when trying to use USRP X310

[Jose Ruvalcaba]

Yes I do. However, I've noticed that when I reboot the radio, the issue does not appear. However, after I switch to another flowgraph, the issue shows up and I need to reboot the radio again. I've attached a screenshot of the issue after trying the test tools in case it helps.

If you use one of the test tools like uhd_fft or any of the purely UHD tools do you see the same issue?

Hi Marcus,

I was using a 1 Msps sample rate in my flowgraph. As for the Ethernet controller, I was currently using my standard 1 GigE Ethernet port on my PC, however, this issue also shows up when using a 10GigE connection. If it helps, the 10 GigE Ethernet card I have is the desktop card sold by Ettus Research.

Thanks,

Jose

Hello,

I recently installed GNU Radio 3.7.13.4 with UHD 3.14 ,using PyBOMBS, and tried to use my X310 radio with it. It asked me to update its FPGA image, and after updating it, I began to see an error whenever I tried using the USRP sink and source block In GNU Radio. The error reads:

Note that I am NOT trying to use RFNOC, which I think this issue is related too, I am just trying to use the x310 with regular USRP blocks in GNU radio.If it helps to know, I am running UBuntu 18.04 and the FPGA image I downloaded on my X310 was the default HG one. Can anyone shine some light into how to get rid of this issue?

Thanks,

Jose R

What sample rate are you using?  Do you happen to know what type of Ethernet controller your PC has?
