>> @Ahmed: >> >> Problem 1: Please describe your hardware setup so that we can help: >> >> a) What USRP model are you using? What GNUradio version, did you install >> the distribution package on Ubuntu 8.04 or upgrade to 11.10 as suggested? >> What was the exact command line you used for usrp_spectrum_sense.py and >> usrp_fft.py? >> b) What daughterboard did you install inside the USRP? How did you >> connect it to the USB port of your laptop, and how to the antenna? >> c) Is the USRP powering up? >> d) After a power cycle (everything just switched on), does >> uhd_find_devices still give you nothing? what about lsusb -v? >> >> In case you managed to get up to d) and have the USRP and >> daughterboard(s) detected correctly, >> >> e) Did you connect the antenna to the appropriate RX channel of your >> daughterboard? When using WBX, there's an RX and an RX/TX port, so if you >> connect the antenna to the wrong port, you might only see noise except for >> a few *very* strong local sources. Try tuning to a local FM radio >> station... Any antenna should do for this purpose, even a paperclip - but >> don't torture the gold plated SMA connectors of the USRP with that :) >> >> Problem 3 is probably caused by Problem 2. I also noticed that sometimes >> the USB stack seems to get messed up, so you might want to try a) power >> cycling your USRP and if that doesn't help, b) power cycling the laptop >> connected to the USRP. >> >>> >> frist of all i have two laptops with ubuntu 11.10 x32bit installed inside windows 7 professional x64, i used this link in synaptic to install gnuradio packages: 11.10 contains 3.2.2.dfsg-1ubuntu7 ( http://packages.ubuntu.com/oneiric/gnuradio) and this guide to install the other packages : http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall#Install-Dependencies After successful installation still there is UHD, i installed it through this: git clone git://code.ettus.com/ettus/uhd.git cd uhd/host mkdir build cd build cmake ../ make make test sudo make install #Check where your path is with "find |grep libuhd" export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib after that i checked: ---------------------------- python worked gnuradio-companion worked gnuradio worked so guide me if i mess something or did something wrong in installation step ? i will provide you with other information about hw setup and what each usrp box contain? in Saturday
