Hi Josh, The sequence of the LEDs is D and F coming green just in the same way as the video apart from the B led where I cannot see why to come green?
The ethernet is properly configured. The green led on the ethernet also goes on. There is no way that the ethernet jack is faulty or sth like that as the same usrp2 with the same settings is just working fine on another laptop with UHD_003.004.000 - 325- g7e296167 revision. I don't really know what's the problem, may be I will try solving it by monitoring the serial output. The thing that really attracted my attention is that sometimes there is a connection and after just typing uhd_find_devices the connection is lost. Any other ideas guys? Thanks again, George On Fri, Apr 13, 2012 at 2:00 AM, Josh Blum <[email protected]> wrote: > > > On 04/12/2012 05:15 PM, George Sklivanitis wrote: > > Hello everyone, > > > > The last 2 days I am dealing with a problem of using gnuradio with > USRP2s. > > > > I have successfully installed both gnuradio and uhd using the > > build-gnuradio scipt into 3 brand new core i-7 laptops. > > > > However, after using the default usrp2_card_burner gui for burning the > > firmware and fpga images into a Kingston 2GB SD card provided with the > > USRP2 I cannot find the USRP2 device neither when using the command > > uhd_find_devices nor by doing ping in 192.168.10.2.
