Hi all, I'm prepared a basic GNU Radio flow-graph that does simultaneous transmission and reception (see the attachment). For USRP X310 and RFNOC UHD (version above 3.10.x) soon after starting the flow-graph there is a lot of buffer underflows (even for low sample rate like 1MS/s). For pre-RFNOC UHD (3.9.6) everything works fine.
What is a bit strange is that txrx_loopback_to_file UHD example works fine for all versions of UHD. Is anybody here able to run GNU Radio flow-graphs with simultaneous tx and rx on X310 with RFNOC UHD and without underflows? Best Regards, Piotr Krysik
