Description

This tutorial is a guide for getting started with RFNoC using an USRP X310 on ORBIT grid. Before starting to experiment with RFNoC, here are a couple of useful presentations, write ups from Ettus Research, that one should go through. ​https://github.com/EttusResearch/uhd/wiki/RFNoC:-Getting-Started

Set up

  • Make a reservation on the ​Orbit Scheduler for using the grid.
  • Load baseline-rfnoc-labtools.ndz on an ORBIT node with USRP X310. 
    omf load -i baseline-rfnoc-labtools.ndz -t node18-20
  • Once imaging is done, turn the node on 
    omf tell -a on -t node18-20
  • Wait for the node to turn on and log in 
    ssh root@node18-20

Testing the installation

The image that was loaded, contains UHD rfnoc-devel branch installation as mentioned in the RFNoC getting started guide.

  • Run uhd_find_devices - you can see that the UHD version is shown as UHD_003.010.rfnoc-285-gb9765c42 
    root@node18-20:~# uhd_find_devices --args="addr=192.168.10.2"
linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.010.rfnoc-285-gb9765c42

    name: hakuna matata
    serial: F4FD2A
    product: X310
  • Run uhd_usrp_probe. This might throw an error as shown below, as the X310 might contain a firmware build that is not compatible with the RFNoC UHD installation.

=========================================================
Warning:
Expected FPGA compatibility number 1000, but got 9:
The FPGA image on your device is not compatible with this host code build.
Download the appropriate FPGA images for this version of UHD.
Please run:

 "/usr/local/lib/uhd/utils/uhd_images_downloader.py"

Then burn a new image to the on-board flash storage of your
USRP X3xx device using the image loader utility. Use this command:

"/usr/local/bin/uhd_image_loader" --args="type=x300,addr=192.168.10.2"

For more information, refer to the UHD manual:

 http://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_flash=========================================================
Error: RuntimeError: Expected firmware compatibility number 4.0, but got 3.0:
The firmware build is not compatible with the host code build.
Please run:

 "/usr/local/lib/uhd/utils/uhd_images_downloader.py"
  • In case of the above error, you can burn the appropriate FPGA image using uhd_image_loader as shown above, or using usrp_x3xx_fpga_jtag_programmer.sh found in uhd/tools.When the jtag programmer is used, the FPGA image is lost on power cycling. 
    root@node18-20:~/uhd/tools# ./usrp_x3xx_fpga_jtag_programmer.sh --fpga-path="/usr/local/share/uhd/images/usrp_x310_fpga_HGS.bit"
