default ip address through Ethernet will be 192.168.10.2

open terminal and type: uhd_find_devices

if you got error no UHD devices found follow these steps if not every thing is ok

type : uhd_images_downloader
**download the images*

type: uhd_image_loader --args="type=usrp2,addr=192.168.10.2"
this will upload the image to FPGA

Restart both laptop and USRP.

tip1: in GNURADIO give addr=192.168.10.2 to the USRP blocks.
use uhd_usrp_probe --args="addr=192.168.10.2"

you should see all details about your N210 after this command.



**Update: If your linux can't recognize N210 thats because your PC should be in the same subnet as your N210 USRP therefore use this:
>ifconfig !!// Here you find your ethernet name in my case: enp0s25
>sudo ip address add 192.168.10.100 dev enp0s25
>sudo ip route add 192.168.10.0/24 dev enp0s25

now use all the instructions in the video:
such as :
>uhd_usrp_probe --args="type=usrp2,addr=192.168.10.2"
or
>namp -T5 sP 192.168.10.0-255




in case this doen't work for you try to install latest UHD version. --> :


First, make a folder to hold the repository.

 cd $HOME mkdir workarea-uhd cd workarea-uhd

Next, clone the repository and change into the cloned directory.

 git clone https://github.com/EttusResearch/uhd cd uhd

Next, checkout the desired UHD version. You can get a full listing of tagged releases by running the command:

 git tag -l

Example truncated output of git tag -l:

$ git tag -l ... release_003_009_004 release_003_009_005 release_003_010_000_000

Note: As of UHD Version 3.10.0.0, the versioning scheme has changed to be a quadruplet format. Each element and version will follow the format of: Major.API.ABI.Patch. Additional details on this versioning change can be found here.

After identifying the version and corresponding release tag you need, check it out:

 # Example: For UHD 3.9.5: git checkout release_003_009_005 
 # Example: For UHD 3.10.1.0: git checkout release_003_010_001_000

Next, create a build folder within the repository.

 cd host mkdir build cd build

Next, invoke CMake to create the Makefiles.

 cmake ../

Next, run Make to build UHD.

 make

Next, you can optionally run some basic tests to verify that the build process completed properly.

 make test

Next, install UHD, using the default install prefix, which will install UHD under the /usr/local/lib folder. You need to run this as root due to the permissions on that folder.

 sudo make install

Next, update the system's shared library cache.

 sudo ldconfig

Finally, make sure that the LD_LIBRARY_PATH environment variable is defined and includes the folder under which UHD was installed. Most commonly, you can add the line below to the end of your $HOME/.bashrc file:

 export LD_LIBRARY_PATH=/usr/local/lib

On Fedora 22/23/24/25 you will need to set the LD_LIBRARY_PATH to /usr/local/lib64.

 export LD_LIBRARY_PATH=/usr/local/lib64

If the LD_LIBRARY_PATH environment variable is already defined with other folders in your $HOME/.bashrc file, then add the line below to the end of your $HOME/.bashrc file to preserve the current settings.

 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

For Fedora 21/22/23/24/25

 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib64
