Cannot detect USRP N210

GNU Radio
1

Hi everybody,

I am using gnuradio 3.2.2. on Ubuntu 10.10 with an USRP N210. I have
installed GNURadio thanks to the binary package installation and GNU
Radio
Companion. Everything went good as I can open grc. I have also
configured my
ethernet card (intel pro/1000GT desktop adapter) on the eth1 interface
to
communicate with the USRP. I can ping the USRP (ping 192.168.10.2) which
means that the computer can communicate with the USRP. But, when I run
find_usrps or usrp2_fft.py on the terminal, I have these messages :

gnuradio@gnuradio-Precision-WorkStation-340:~$ find_usrps
No USRP2 found.

or

gnuradio@gnuradio-Precision-WorkStation-340:~$ usrp2_fft.py -e eth1
Traceback (most recent call last):

return _usrp2.source_32fc(ifc, mac)

I have tried to install GNURadio by the other ways but the problem
remains.
I have searched a lot on forums and I have tried a lot of things without
succeeding to detect the USRP. Do you have any solutions ? Thank you
very
much

Those applications were written for the old usrp2-gnuradio driver. See
UHD + gnuradio:

The N210 is a UHD-only device. You’ll need a more recent version of Gnu
Radio, and you’ll
need to follow the UHD build instructions here:

http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki

Also, find_usrps, and usrp2_fft.py are “classic” API programs–they
won’t work with UHD devices.

But you can synthesize the functionality of usrp2_fft.py for UHD within
GRC pretty easily.

You can use uhd_find_devices (once you have UHD, and Gnu Radio
compatible with UHD) to find
UHD-type devices.

Hi,

First, thank you for yours answers. I did not see that point and so I
re-install gnuradio and uhd as showed in the link you gave me using the
git.
Everything went good but when I run uhd_find_devices, I have this
message :

#gnuradio@gnuradio-Precision-WorkStation-340:~$ uhd_find_devices
#linux; GNU C++ version 4.4.5; Boost_104200;
UHD_002.20110206225409.aea6ac1

#Warning:

Ignoring discovered device

Expected protocol compatibility number 8, but got 7:

The firmware build is not compatible with the host code build.

#No UHD Devices Found

Do I have to update directly the firmware installed on the USRP ? or it
is
just a problem on the computer ? Thank you again.

Dear all,

I have just received 4 usrp N210 and I’m trying to start working on. I
installed on a laptop (Dell Vostro with Ubuntu 10.04 Lucid ), Gnuradio
and UHD, but I’m not able to communicate with the Usrp: when I connect
the ethernet cable between the laptop and the USRP and I plug the power,
only led B and F shows up, and on the ethernet port the orange led on
the right is always opened.
I have tried to type “uhd_find_devices”, but all the time the response
is:
"
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.001.000-0aff497

No UHD Devices Found "

I cannot ping the device, and even thought I try to enable the ethernet
connection, after a while it turns in a disable mode, because it seams
that nothing is connected to the laptop.

If someone could be very kind to help me, I’ll be very grateful.
Thanks in advance for all your help
