All:
I'm having trouble with some flowgraphs under Ubuntu 18.04.1. I
recently set up a HP ZBook G3
with that OS and did a PyBOMBS install of gnuradio and UHD. I'm
connected to an Ettus X310
and the SBX daughter card here.
I then starting running some of the flowgraphs I had been running
under 16.04 on that same
computer. I hadn't observed any errors with these flowgraphs under
16.04.
After running for a while, I get the following error:
gr::log :WARN: gr uhd usrp source0 - USRP Source Block caught rx
error code: 255
The flowgraph doesn't appear to stop, but the graphics I'm running
using QT GUI Vector Sink
freeze up. I can then stop the flowgraph in the usual way by
clicking the "kill the flowgraph"
button.
kernel: 4.15.0-29-generic #31-Ubuntu SMP
gnuradio version: 3.7.12.0
UHD version: UHD_3.14.0.0-31-g98057752
Any ideas of how to fix this problem?
Here is the output of uhd_usrp_probe:
