Hello Guys,
I am using usrp x310 with default XG image. I have also setup the RFNoC
platform in GNURadio with gr-ettus.
RFNoC ddc example using RFNoC blocks works perfectly with 100MHz of
bandwidth. But when I go back to using normal usrp source block which is a
normal gr-uhd block, it throws the following error.
