Are you using a release of GNU Radio or a build from git?
I do "sudo find_usrps" and I only get one line of output that says No USRP2 found. I have tried both the binary and the git builds, but for the rest of this email I am using GNU Radio 3.2.2 installed from the binary distribution on Ubuntu 9.10 from the following source repositories: deb http://gnuradio.org/ubuntu stable main deb-src http://gnuradio.org/ubuntu stable main deb http://mirrors.kernel.org/ubuntu jaunty main universe >> >> I have reached a point that I am almost certain there is something wrong >> on the USRP2 side.

There are many other variables. Is the USRP2 connected directly to the ethernet card? Are you certain it is a gigabit ethernet card? Can you send the output of dmesg after connecting the USRP2? Do you have a TTL serial adapter? I have connected the ethernet card (which is a gigabit one) directly to the USRP2 and assign a manual IP using "ifconfig eth0 10.0.0.2."

You'll need to follow the instructions again, as those instructions work. If the LEDs don't light up, then the files are not on there and nothing will work. I will re-do this with a new SD-card and report the results. >> >> How do I know which version of firmware and FPGA bitstream I should use? >> Is there a u2_rev4.bin available (since my USRP2 is revision 4)? >> Any hints on what I might be doing wrong? > > No, rev3 and rev4 use the same .bin files. > > Matt I highly appreciate your time.
