Siapkan Aplikasi Pendukung

apt-get install git python-cheetah python

Download

echo "/usr/local/lib" >> /etc/ld.so.conf
cd /usr/local/src
git clone git://ettus.sourcerepo.com/ettus/uhd.git uhd.git

Compile

cd /usr/local/src/uhd.git/host/
mkdir build
cd /usr/local/src/uhd.git/host/build
cmake -DENABLE_LIBUHD=ON -DENABLE_EXAMPLES=ON -DENABLE_UTILS=ON -DENABLE_TESTS=ON -DENABLE_USRP1=ON ../
make
make test
make install
ldconfig

Install UHD USRP ke udev

cd /usr/local/share/uhd/utils
sudo cp uhd-usrp.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules

Install Image 003.004.002-180-gb6bb13bc

Download UHD image 

cd ~
wget http://files.ettus.com/binaries/master_images/archive/uhd-images_003.004.002-180-gb6bb13bc.tar.gz

Install 

rm -Rf /usr/share/uhd/images/*
rm -Rf /usr/local/share/uhd/images/*
cd ~
tar zxvf uhd-images_003.004.002-180-gb6bb13bc.tar.gz
cp -Rf uhd-images_003.004.002-180-gb6bb13bc/share/uhd/images/ /usr/local/share/uhd/

Dalam /usr/local/share/uhd/images/ , file

  • usrp1_fpga_4rx.rbf
  • usrp1_fpga.rbf

digunakan untuk USRP1

Test

Test clock 52MHz

cd /usr/local/bin
./uhd_usrp_probe --args="master_clock_rate=52e6"

Hasilnya kira-kira 

linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.004.003-175-g09de3c07
