Are there restrictions regarding which DDC ports must be connected to which
Radio ports. I am using an X310/UBX with a custom C++ rfnoc application
and would like to do the following:
Radio_0:port0 -> DDC_0:port0
Radio_1:port0 -> DDC_0:port1
Unfortunately, this fails (using default FPGA image) with a recv() after
about 3K samples. If I simply change the 2nd link above to the following,
then everything is fine.
Radio_1:port0 -> DDC_1:port1
Why is the first config invalid? If this is a bug, is it presently being
FYI, my UHD version is UHD_184.108.40.206-20-gf63c089a.
