RuntimeError: No USRPs found on interface eth0

Hello,

I am using USRP2 with a EEE PC (1015PX) which has ubuntu 11.04 on it.
Since
the USRP2 communicates only gigabit, I bought a Linksys SE2800 Gigabit
Ethernet switch and connected the USRP2 via the Ethernet Switch (The EEE
PC
does not have a gigabit ethernet card). I switched on the USRP2 and I
got
the D and F led lights on after all the led lights flashing. I run the
usrp2_fft.py program and I got this error:

[email protected]:~# usrp2_fft.py
Traceback (most recent call last):
File “/usr/bin/usrp2_fft.py”, line 273, in

in
source_32fc
return _usrp2.source_32fc(ifc, mac)
RuntimeError: No USRPs found on interface eth0

Then I tried to ping the usrp2 by connecting it to my laptop which has a
gigabit ethernet, but I don’t get any response from it. The request is
timed-out everytime. I also tried all the solutions possible from the
list,
nothing works for me.

Please Help.

Hello Nick,

I uninstalled everything and was going through the build guide to
install
gnuradio and I got this error this time:

./bootstrap
./bootstrap: 25: aclocal: not found
./bootstrap: 26: autoconf: not found
./bootstrap: 27: autoheader: not found
./bootstrap: 28: libtoolize: not found
./bootstrap: 29: automake: not found
./bootstrap: 25: aclocal: not found
./bootstrap: 26: autoconf: not found
./bootstrap: 27: autoheader: not found
./bootstrap: 29: automake: not found
./bootstrap: 26: aclocal: not found
./bootstrap: 27: autoconf: not found
./bootstrap: 28: autoheader: not found
./bootstrap: 29: libtoolize: not found
./bootstrap: 30: automake: not found

I could not solve this one, So I got another EEE PC, which dint have gnu
radio before, I installed gnuradio in that and I got the same error as I
mentioned in the first message.

@Marcus: I did upgrade the firmware and fpga image on the SD Card. I
used
the the Raw Ethernet image for the FPGA and Raw Ethernet with WBX for
the
firmware.

gigabit ethernet, but I don’t get any response from it. The request is
API stuff, then I strongly recommend upgrading your
“world” to UHD.

I’m going to recommend that you start fresh, using the build-gnuradio
script:

http://www.sbrac.org/files/build-gnuradio

Which will download, build, and install everything, including putting
UHD firmware images in /usr/local/share/uhd images.

If you have no prior investment in the “classic” API for USRP2, then you
really, really, ought to be using UHD. The build-gnuradio script
generally makes it quite straightforward. It does take a long time
to run, since it has to download not only the source code for
UHD and Gnu Radio, but also all the pre-requisites for building Gnu
Radio and UHD.

Also, an EEE PC 1015PX isn’t likely to have stellar performance. It
will perhaps allow you to get your feet wet, and perhaps, for
lightweight
flow-graphs, process as much as 2GHz of bandwidth.

hey its written use uhd_fft.py instead of usrp2_fft.py but the problem
is their is no uhd_fft.py file available, now tell me what to do.

As other uhd related files are working perfectly i.e uhd_usrp_probe and
etc.
i just want to confirm out of curiosity that my USRP2 is working
properly…??

Thanks
Harsh
