N310 configuration and access

Description

This tutorial shows how to configure and access the N310 SDR from an experiment server. The N310 is used as a network based USRP which has a 1Gb control interface and a 10Gb data interface. Both interfaces need to be configure properly for control and data streaming. Product information for the N310 is here.

Network configuration

From a COSMOS console, load a baseline sdr image onto an experiment server - for this example srv1-lg1.sb1.cosmos-lab.org is used.

console> omf load -i baseline-uhd-1804.ndz  -t srv1-lg1.sb1.cosmos-lab.org
console> omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org

After the experiment server is up, ssh into it and list the all interfaces.

  • en01 is the 1Gb control interface.
  • enp1s0 is the 10Gb data interface

Configure enp1s0 so it can talk to the N310's data interface.

> sudo ifconfig enp1s0 10.115.1.1 netmask 255.255.0.0 mtu 8000

Run uhd_find_devices to detect the available N310s

Trouble shooting

The FPGA bit file will need to be updated if FPGA version mismatch is generated in the output text of the uhd command above. Follow the steps below to update the FPGA image - this will download and install the FPGA image that is matched with the UHD version being used. Complete details on updating the FPGA is found here.

> sudo uhd_images_downloader
> uhd_image_loader --args "type=n3xx,addr=10.113.2.1,fpga=HG"

After the image loader completes, power-cycle the N310 from the console and detect the N310 again.
