LibreSDRB210 - USRP B210 Setup Guide

Important update: This project has been updated for the Artix-7 XC7A100T version, including IP upgrades and regenerated build targets. It was successfully compiled on Ubuntu MATE 24.04.4 LTS using Vivado ML Standard Edition 2024.1. In addition, the source DACx311_auto_spi.v was modified, compiled, and successfully validated for the DAC7311IDCKR.

This repository contains essential files and instructions for setting up the USRP B210 with custom firmware on Linux. Follow the steps below to install the required drivers and replace the default B210 image with the custom one from this repository.

Software and Information

I did not design this software, nor the board. I cannot answer questions about the project as I am not an FPGA developer. This repository merely exists as a means for users to be able to easily download the binaries needed to get these clones working. If you or someone has an issue, feel free to fork this repository and make changes. Otherwise, please contact the seller or manufacture of the device as I will be of no help. These files are provided AS-IS.

Prerequisites

• Ubuntu Linux or another Debian-based distribution
• A USRP B210 LibreSDR clone (XC7A100T+AD9361 ONLY)
• Git installed on your machine

Installation Steps

1. Install USRP Hardware Drivers (UHD)

First, you'll need to install the USRP Hardware Drivers (UHD) for your device.

Open a terminal and run the following commands:

$ sudo add-apt-repository ppa:ettusresearch/uhd
$ sudo apt update
$ sudo apt install libuhd-dev uhd-host

Install Python3 (If not already installed)

$ sudo apt install python3

Download UHD Images

Next, you need to download the UHD images used by the USRP devices. Run the following command to install the images:

sudo /usr/lib/uhd/utils/uhd_images_downloader.py

The images will be downloaded to: /opt/local/share/uhd/images

Replace the B210 Image

Replace the default B210 image in /opt/local/share/uhd/images with the custom image provided in this repository.

wget https://github.com/lmesserStep/LibreSDRB210/raw/main/usrp_b210_fpga.bin
cp usrp_b210_fpga.bin /opt/local/share/uhd/images

Verify

Any of the changes needed will require Vivado, this is a working bin. Please note, this has been tested on versions 4.0-7.0 UHD from Ettus Labs.
