GUIDE: How to start running your USRP N210

Here below are listed all the steps that you need to make your USRP N210 work:

• mount the daughter-board inside the USRP: make sure that the 4 holes at the corner of the daughter board line up with the holes in the USRP.

• connect each BNC on the daughter-board respectively to the RF1 and RF2;

• install Ubuntu 10.04 Lucid on your laptop/desktop (you can install any Ubuntu's version)

• open the terminal

• make sure that you saved the file build-gnuradio on your current folder, and then type:

chmod 755 build-gnuradio

./build-gnuradio

The code inside the file build-gnuradio is going to install the most recent version of UHD and gnuradio, and is going to get from git and install

all the packages that are needed to make the USRP N210 work.

• connect the laptop/desktop to the USRP N210 by an ethernet cable

• plug the power: if this is the first time that you are using the USRP you should see led B and F open (green color), and the orange led on the ethernet port open too; otherwise led D and F and the green led of the ethernet port should be open (green color).

• if led D is open, jump to the next step, otherwise:

1. download the most recent FPGA image and the last firmware from: http://www.ettus.com/downloads/uhd_releases/003_001_000/images-only/

2. type the following code in order to set you ethernet board

sudo ldconfig

sudo ifconfig eth0 192.168.10.1

3. try to enstablish a communication with the USRP typing

ping 192.168.10.2

4. type the following code, just to make sure the device is opportunely installed

uhd_find_devices

5. type the following code in order to install an additional package

sudo apt-get istall python python-tk idle python-pmw python-imaging

6. install the firmware and move an image of the FPGA on the motherboard of the USRP typing the following code:

sudo /uhd/host/utils/usrp_n2xx_net_burner_gui.py

7. you should see a GUI as below and you should link the FPGA image and firmware that we have downloaded before

and use address ”192.168.10.2”

8. wait until the firmware and the FPGA image are succefully loaded into the USRP and then wait for the reset.

9. if the procedure succede, you should see led D become green.

You are now ready to use and enjoy your USRP N210. Remember that everytime you are going to use the USRP on your laptop/desktop you should type

sudo ldconfig

sudo ifconfig eth0 192.168.10.1

unless you prefer to set the address of your ethernet board in a permanent way using : System− > Administation− > Network tools.

This setting is suggested only and only if the laptop/desktop that you are using is dedicated to work on the USRP N210.
