Hello,
I am trying to get a GSM air interface set up running using USRP2, UHD,
GNURadio.
I have installed the latest UHD, using GNURadio 3.3.0. The OS is Ubuntu
10.04 LTS. I have installed UHD before GNURadio.
I have connected the USRP2 to a Gigabit Ethernet port of my PC at eth0.
I am
able to ping:
root@edcn311:/usr/local/bin# ping 192.168.10.2
PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data.

Then when I try to run uhd_find_devices, its all ok:
root@edcn311:/usr/local/bin# uhd_find_devices
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.001.002-unknown
– UHD Device 0
Device Address:
type: usrp2

But when I try running the usrp2_fft.py, I am not successful.
root@edcn311:/usr/local/bin# usrp2_fft.py

I am not able to proceed further because of this. Kindly help.
