I've been struggling with the exact same bug with uhd on the e310. I'm
trying to compile it to use RFNOC. Has a fix for this been resolved? I'm
new to using the e310 and have no idea how to get past this. Unlike the
the original poster, I am unable to run anything with uhd, the examples
stop be
Hello,
I've followed the directions as specified here :
https://kb.ettus.com/Software_Development_on_the_E310_and_E312
to cross compile uhd for the e310 such that I can use RFNOC
Everything looks good until I get to here. I'm new to the e310 and rfnoc
so any advice on how to proceed would be appr
Has anyone recently tried rfnoc loopback?
I tried following these directions:
https://corvid.io/2017/04/22/stupid-rfnoc-tricks-loopback/
they are dated from last April. Not sure if I missed a step or maybe there
is something new in gr-ettus and uhd-devel?
Thanks,
Jack Ziegler

Hello,
I'm using gnuradio with the usrp_source block. What I'm trying to do is
rapidly retune between 24 Msps and 12 Msps, and possibly other arbitrary
rates too shortly.
This is easy to do with a B200 series radio using the usrp_source block and
the command message port by sending a PMT message
Msps very easily... I'd imagine a "rapid"

Hello,
I'm trying to make a uhd program that is basically the rfnoc version of the
non-RFNOC Tx_waveforms example in uhd/host/examples.
What I am trying to do is transmit samples (from a wave table for example),
using the rfnoc radio block.
Note that I am cross compiling for an E310 usrp. Also
All,
I'm having an odd issue that is occurring on an E312. I've tried this same
code on different e310's and it works fine. Hadn't used the E312 in a while
and now when i try to run gnuradio code or even just run uhd_usrp_probe I
get errors like below. Any ideas how to fix this?
Thanks!
Jack
