With help from Jonathon, this issue has been resolved. The basic steps
taken that might assist others:
1) Used 4 RFNoC radio blocks for dual full duplex, used the dma fifo for
the tx chains and reduced its size to limit the delay out to the antenna
for low sample rates.
2) Implemented part of the

I'm using 1GigE and running at 2Msps (and lower). Unfortunately I cannot
use jumbo frames (9000 mtu) as currently our x310's are on a network not
setup for them (which breaks other things if enabled). The weird thing is
the underruns only occur with the 4 rfnoc radio blocks, they don't o
Hi Mike,
Make sure your MTU is set to 9000. Are you using 1GigE or 10GigE? Do you
see underruns improve when running with only 1 TX radio?

Hi,
I'm using gnuradio 3.7.12 and rfnoc-devel commit 1908672.
I'm trying to use both daughter boards on the x310 each at full duplex
(that is, I will have 2 independent tx paths and 2 independent rx paths).
So far I have accomplished this by using the UHD: USRP Sink/Source blocks
and setting them
