Re: [Discuss-gnuradio] A strange problem with "No UHD Devices Found", when ping 192.168.10.2 is ok

[Jiao Xianjun]

Seems that I find the problem:

uhd_usrp_probe --args="addr=192.168.0.2"
linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.000-307-gb61f4ad6

Hi,

I just got a USRP N210 rev4.0, and install gnuradio+uhd with this script: http://www.sbrac.org/files/build-gnuradio in Ubuntu 11.10 (32bit).
My eth config is:

and I do can ping 192.168.10.2:

^C

but when I run uhd_find_devices, the outputs are:

linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.000-307-gb61f4ad6

No UHD Devices Found

Any one can help me, or give me some information?

Thank you so much!
