Unable to find usrp2 with latest uhd driver

GNU Radio

Hi

I downloaded the latest uhd driver from Ettus and gnuradio with uhd. I
believe i have all dependencies and installed uhd and gnuradio
correctly. After ./configure, i can also see gr-uhd. I’m using the
latest fpga_image (u2_rev3_uhd_20100706.bin) and firmware image
(txrx_uhd_20100706.bin).

When i type uhd_find_devices --args addr=192.168.10.2, i get the
following message:

pnmyint@ubuntu:~$ sudo uhd_find_devices --args addr=192.168.10.2
[sudo] password for pnmyint:
linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.000.001-8212f22

I can ping to the usrp2. This is what i have with ethtool eth0 command:

pnmyint@ubuntu:~$ sudo ethtool eth0

Do I have to build fpga and firmware to match the latest uhd host
driver? Any suggestion is welcome.

Hi there,

That time my problem was due to the fpga and firmware image. I was using
outdated .bin files. Are you building your own fpga and firmware image?
You can get the latest .bin file. Hope that help.
