Re: "uhd_find_devices" command returns "No, UHD Devices Found"

GNU Radio
1

I use UBUNTU 10.10.
I configured eth0 for a static address 192.168.10.2. by setting “Network
connections” in “System->Preferences”. Connection is enabled, however,
“uhd_find_devices” cannot find any devices.

The result of ‘sudo ./uhd_usrp_probe --args “addr=192.168.10.2”’ is
below.

jupiter@jupiter-Prime-Series:/usr/local/bin$ sudo ./uhd_usrp_probe
–args “addr=192.168.10.2”
linux; GNU C++ version 4.4.5; Boost_104200; UHD_003.004.000-07c9d41

command worked for a while, however, after some time, returned “No UHD
Devices Found”.

I want to know why the return of “uhd_find_devices” command changed to
“No UHD Devices Found”.

Is perhaps Network Manager taking your ethernet interface down? It
needs to be configured
for a static address assignment with no DHCP.

Also, what happens when you:

uhd_usrp_probe --args “addr=192.168.10.2”

192.168.10.2 would be the default address of the usrp. Try a different
address in the subnet for your network card. Also read:
