Problem in find_usrps and usrp2_fft.py on USRP N210

Hi All

I hope that u all r fine and doing good. I have a problem in accessing
USRP N210. I installed UHD driver and all the images necessary. when i
run uhd_find_devices.py, it returns me

linux; GNU C++ version 4.4.3; Boost_104000;
UHD_002.20110127203211.8a62a20


– UHD Device 0

Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial: E2R10ZFUP

which means that the UHD driver is installed correctly. But when i try
to run find_usrps, i got “No USRP2 found”. Secondly when i try to run
usrp2_fft.py i get the following message:

Traceback (most recent call last):
File “/usr/local/bin/usrp2_fft.py”, line 273, in

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

Please help me in this regard.

Thanking all of you in anticipation.

both “find_usrps” and “usrp2_fft.py” use the “classic” API for the USRP2
hardware, and so don’t
work with UHD devices.

You can synthesize the functionality of usrp2_fft.py using GRC in about
5 minutes, and I posted a link
to a GRC+UHD implementation in the last couple of weeks on the mailing
list.
