Hello,

I installed and tried to run the simple_ra_receiver flowgraph using a USRP
N210 and was shown the following error message:

















*aster$ simple_raUsing Volk machine: avx_64_mmx_orcgr-osmosdr

I updated osmosdr to the latest version from*
https://github.com/osmocom/gr-osmosdr
<https://github.com/osmocom/gr-osmosdr>*
but I still get the same issue.

Any ideas?

Thanks,
Jose
