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

[Marcus Leech]

Gah!

I missed the second-half where nesazeri was using find_usrps.

 

Indeed, if you have software that uses the "classic" (pre-UHD) interface, that interface has been obsolete for several years and is no longer

  supported.  The N2XX in particular, *does not* support the "classic" interface.

The solution is the USRP2 interface is no longer supported, and software which uses it must be ported to UHD. The find_usrps tool is no longer usable with modern Ettus hardware.

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

-- UHD Device 0

Device Address:
    type: usrp2
    addr: 192.168.10.2
    name:
    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?
