Hi all, I recently purchased a USRP X310, and a pair of UBX daughter boards, that I would like to use to for waveform testing. However, I have not been able to get basic operation on the radio working properly with GNURadio. I am able to receive a tone when running a receiving GNURadio flowgraph with a 'USRP Source' block using the attached GNURadio flowgraph "x310_receive_test.grc". On the other hand, when I try a transmitting flowgraph with a 'USRP Sink' block fed by any signal (complex sinusoid, noise, constant) using the attached flowgraph "x310_transmit_test.grc", GNURadio stops and no samples seem to be streaming to the device. Once I kill this flowgraph and try to restart it I get the following print out from GNURadio:

After this point I can't get the USRP to transmit or receive - it appears to be
stuck in a bad state. The only way to get the USRP to even receive again is to
power cycle the unit. I have a suspicion that something is going wrong between
the UHD version/GNURadio version/FPGA image on the USRP, but am not sure how to
proceed. I installed what I believe to be the newest version of GNURadio,
version 3.7.13.4, using pybombs. For more context, here's what is printed when
I call uhd_usrp_probe before getting the radio stuck in this bad state:
