I’m using Ubuntu 14.04, gnuradio 3.7.8, USRP N210 and the latest UHD.
Everything was recently (3 days ago) updated to newest versions and
reflashed. I have custom flowgraphs that use the USRP N210’s that work
I decided to play around with the benchmark_tx and benchmark_rx scripts
see what they could do, but I’m not able to receive anything because a
segmentation fault crashes the benchmark_rx script as soon as I start
tx script. Even with the -v flag, I don’t get any error output other
‘Segmentation fault (core dumped)’.
Here is an example of the commands I use to start the scripts. I start
rx and then the tx.
TX: ./benchmark_tx.py -v -f 1000000000 -r 800000 --args=“addr=10.0.8.5”
RX: *./benchmark_rx.py -v -f 1000000000 -r 800000 --args=“addr=10.0.8.4”
RX2 --rx-gain=15 *
Am I doing something wrong on my end or is there a script issue?
I use pybombs to update, which automatically updates UHD first and then

OK, then I have no clue. If you can present a stack trace here, someone
might have a better idea.
I remember I had the same issue before when testing the benchmark. What
did to avoid the crash is to start the tx first, and then the rx. It
that you are doing it in reverse order, which is reasonable but not
according to my test.

I forgot to mention that I also re-cloned pybombs before doing the
So to be explicit, I deleted the target and pybombs directory. I then
re-cloned pybombs and performed a new ./pybombs install gnuradio. This
recognized I had all dependencies installed via rpm and only needed to
remove and re-install uhd and gnuradio. It then did this.
As I mentioned, my custom radio flowgraph is working on this updated
