Install the x310 daughterboard according to the Ettus Wiki.
The following instructions are for setting up UHD 4.1 and GNUradio 3.9
on Ubuntu 18.04.3 LTS.
Note: UHD 4.1 adds support for USRP x410.
Note: GNUradio 3.10 fails to compile as of March 30, 2022.
Make sure you have the latest distribution packages.
sudo apt-get update && apt-get upgrade
Ensure you have python3 (3.6+) installed. Install pip3.
sudo apt-get install python3-pip
Set the pythonpath in ~/.bashrc.
export PYTHONPATH=/usr/local/lib/python3/dist-packages/:$PYTHONPATH
Important: Install the latest boost libary after installing the dependencies for the UHD from the Ettus website, otherwise the latest version of boost will be overridden by the apt packages of boost.
Download and install the latest boost library.
wget https://boostorg.jfrog.io/artifactory/main/release/1.78.0/source/boost_1_78_0.tar.bz2
tar -xzfv boost_1_78_0.tar.bz2 / if this doesn't work try : tar jxSf boost_1_78_0.tar.bz2
cd boost_1_78_0.tar.bz2 / if "tar jxSf boost_1_78_0.tar.bz2" has been used previously then use "cd boost_1_78_0" instead
./bootstrap.sh --prefix=/usr --with-python=python3
./b2 stage -j3 threading=multi link=shared
Run tests.
pushd tools/build/test; python3 test_all.py; popd
All 166 tests should pass. Next, complete the install as root.
sudo su
./b2 install threading=multi link=shared
exit
Add an iptables rule to allow data from udp port 49152.
sudo iptables -A INPUT -p udp --sport 49152 -j ACCEPT
Make the iptables rule persistent across reboots
sudo apt install iptables-persistent
sudo su
iptables-save > /etc/iptables/rules.v4
exit
Follow the instructions in the Ettus Wiki on building from source. Install the dependencies mentioned, then come back here.
Note: The PyBombs installer installs an outdated version. Instead, build UHD 4.1 from source.
git clone --branch UHD-4.1 https://github.com/ettusresearch/uhd.git
cd uhd/host/
mkdir build
cd build
cmake ..
Note: Building/compiling with GNU make takes a long time. To speed up these builds you can use make -jN where N is the number of parallel builds.
For example, to have 3 parallel build threads, use
make -j3
Install and build to default prefix /usr/local/lib, using parallel threads as necessary.
make
make test
sudo make install
sudo ldconfig
Check the UHD installtion.
uhd_config_info --version
Should be version 4.1.
After installing UHD, we need to install the FPGA images in the USRP.
Download the FPGA packages using the following script in utils.
sudo python3 uhd_images_downloader.py
Next, install the image in the USRP using the uhd_image_loader script.
Note: If you get " No devices found for ----->" error when trying to run uhd_find_devices, ensure that you have the iptables rule in place.
Note: If you are following the Ettus daughterboard installation wiki, note that the uhd_fft utility is not installed by UHD, but rather by GNUradio.
Follow the instructions from the wiki. Additional notes are given below.
Note: I used the maint-3.9 branch.
The maint-3.10 branch throws errors related to numpy.
Note: Don't forget to install volk separately.
Note: Don't forget to install dependencies from here before starting. I installed all the dependencies Bionic Beaver through Focal Fossa.
Make complains about gcc-7 being too old. Thus, install gcc-8 as follows.
sudo apt-get install gcc-8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 700 --slave /usr/bin/g++ g++ /usr/bin/g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 800 --slave /usr/bin/g++ g++ /usr/bin/g++-8
Check gcc configuration to make sure gcc-8 is default.
sudo update-alternatives --config gcc
Install pygccxml for python3
sudo apt-get install -y python3-pygccxml
pybind11 is needed for gnuradio python support.
Install pybind11 from source. Clone the pybind11 library from Github.
During the install, you will run into error regarding pytest.
To solve, run the following.
/usr/bin/python3.6 -m pip install pytest ====> if this doesnt work try: sudo apt-get install gnuradio python3-packaging and skip the next step.
Then do the standard make process as follows:
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig
I did have to reboot to get pybind11 working.
sudo reboot
Install pyqtgraph. Not sure if this is necessary.
sudo pip3 install pyqtgraph
When done with the install, don't forget to update shared libraries.
sudo ldconfig
Check gnuradio install as follows:
gnuradio-config-info --version
Follow the guide below, if the usrp and daughterboards are assembled already, start at step 12
