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:
Executing: /usr/bin/python2 -u /home/satrnground/Downloads/simple_xponder.py

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
