Re: [Discuss-gnuradio] USRP2 connection problem

[mehmet kabasakal]

Hi everyone,

I solved the problem about the USRP2 connection.
The problem was the fgpa and firmware images.
My mistake was burning UDP images on this link to the SD card which
are for experimental usage
http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries

I changed the images to raw ethernet and everything worked fine.

Thanks everyone for your help.

Mehmet.
