Re: [Discuss-gnuradio] No USRPs found on interface eth0

[Marcus Leech]

Try:

uhd_usrp_probe --args "addr=192.168.10.2"

 

Also, be certain that Network Manager isn't resetting the interface back to DHCP (automatic IP address selection).  If Network Manager "owns"

  the interface, *and* the interface isn't configured for static-IP according ot Network Manager, it'll keep trying DHCP, fail, and then take

  the interface out of service.

 

Also, be certain that your network interface supports 1GiGe.

 

And there's absolute NO reason to run any of this stuff as root.  None at all.

Dear All,

I will ask you very old and classical question:
'RuntimeError: No USRPs found on interface eth0'

I have USRP N200

I run:
$ sudo ifconfig eth0 192.168.10.1
$ uhd_find_devices
linux; GNU C++ version 4.4.1; Boost_103800; UHD_003.005.004-140-gfb32ed16

    serial: F3F0D3
$ sudo find_usrps
No USRP2 found.

    return _usrp2.sink_32fc(*args, **kwargs)
RuntimeError: No USRPs found on interface eth0

Can you please help me to find a solution to this problem?
