Handling USRP

Khusus untuk Ubuntu 12.04 kita tidak bisa menggunakan SYSFS, ganti menjadi ATTR, juga ada beberapa perubahan lainnya Referensi: http://ubuntuforums.org/showthread.php?t=1985915 dan http://askubuntu.com/questions/147272/problem-with-executing-udev-rules-for-olimexs-avr-usb-jtag

Ubuntu menggunakan udev untuk menangani hotplug devices, dan secara default tidak memberikan akses non-root ke USRP. Script berikut akan memberikan akses bagi user untuk menghandel USRP via USB baik secara live atau hot-plug. 

sudo addgroup usrp
sudo usermod -G usrp -a <YOUR_USERNAME>
echo 'ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="fffe", ATTR{idProduct}=="0002", GROUP="usrp", MODE="0666"' > tmpfile
sudo chown root.root tmpfile
sudo mv tmpfile /etc/udev/rules.d/10-usrp.rules

Pada titik ini, Ubuntu telah di konfigurasi untuk tahu apa yang harus di kerjakan jika medeteksi USRP di USB tapi "udev" perlu me-reload rules untuk memasukan rules yang baru kita buat. Langkah berikut dapat dilakukan sehingga kita tidak perlu me-reboot komputer. 

sudo udevadm control --reload-rules

atau 

sudo /etc/init.d/udev stop
sudo /etc/init.d/udev start

atau 

sudo killall -HUP udevd

Kita dapat mencek jika USRP telah di kenali dengan mengamati /dev/bus/usb setelah USRP di pasang menggunakan perintah 

ls -lR /dev/bus/usb | grep usrp

Harusnya akan keluar seperti 

crw-rw---- 1 root usrp 189, 1 2010-12-09 17:38 002


Setiap USRP yang terpasang akan terdaftar pada group 'usrp' dan mode 'crw-rw----'.

Instal SWIG

Install secara manual SWIG 

Download dari http://sourceforge.net/projects/swig/files/swig/
cp swig-2.0.7.tar.gz /usr/local/src/
cd /usr/local/src/
tar zxvf swig-2.0.7.tar.gz 
cd /usr/local/src/swig-2.0.7/
./configure
make
make install

Instal QWT

Install secara manual QWT 

Download dari http://sourceforge.net/projects/qwt/files/
cp qwt-6.0.1.tar.bz2 /usr/local/src/
cd /usr/local/src/
tar jxvf qwt-6.0.1.tar.bz2 
cd /usr/local/src/qwt-6.0.1/
qmake
make
make install

Install GNURadio

Sebaiknya pada saat melakukan instalasi GNURadio, kita pasang USRP ke USB port-nya.

Download aplikasi GNURadio dari 

http://gnuradio.org/redmine/attachments/download/261/gnuradio-3.4.1.tar.gz
http://gnuradio.org/redmine/attachments/download/279/gnuradio-3.4.2.tar.gz

Install GNURadio 

cp gnuradio-3.4.2.tar.gz /usr/local/src/
cd /usr/local/src/
tar zxvf gnuradio-3.4.2.tar.gz 
cd /usr/local/src/gnuradio-3.4.2/

Patch untuk 52MHz

Edit 

vi /usr/local/src/gnuradio-3.4.2/usrp/host/lib/usrp_basic.cc

Ubah line 110 menjadi 

//  d_verbose (false), d_fpga_master_clock_freq(64000000), d_db(2)
    d_verbose (false), d_fpga_master_clock_freq(52000000), d_db(2)

Edit 

vi /usr/local/src/gnuradio-3.4.2/usrp/host/lib/db_bitshark_rx.cc

Ubah line 151 menjadi 

// set_clock_scheme(0,64000000);
set_clock_scheme(0,52000000);


OpenBTS 2.6 JANGAN LUPA

  • modifikasi OpenBTS.config agar TRX.Path "../Transceiver52M/transceiver".

Compile & Install

cd /usr/local/src/gnuradio-3.4.2
./configure --disable-usrp2 --enable-usrp
make clean
make all
make
make check
make install
sudo ldconfig

Edit bashrc

Masukan PYTHONPATH dengan cara mengedit 

vi ~/.bashrc

Tambahkan 

PYTHONPATH=/usr/local/lib/python2.7/dist-packages
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/

Untuk memastikan ada baiknya lakukan 

sudo ldconfig
export PYTHONPATH=/usr/local/lib/python2.7/dist-packages
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/


Test

Boot komputer. Sambungan USRP. Lakukan 

cd /usr/local/src/gnuradio-3.4.2/gnuradio-examples/python/usrp
./usrp_benchmark_usb.py

Hasilnya 

Testing 2MB/sec... usb_throughput = 2M
ntotal    = 1000000
nright    = 998137
runlength = 998137
delta     = 1863
OK
Testing 4MB/sec... usb_throughput = 4M
ntotal    = 2000000
nright    = 1998117
runlength = 1998117
delta     = 1883
OK
Testing 8MB/sec... usb_throughput = 8M
ntotal    = 4000000
nright    = 3998437
runlength = 3998437
delta     = 1563
OK
Testing 16MB/sec... usb_throughput = 16M
ntotal    = 8000000
nright    = 7998859
runlength = 7998859
delta     = 1141
OK
Testing 32MB/sec... usb_throughput = 32M
ntotal    = 16000000
nright    = 15996766
runlength = 15996766
delta     = 3234
OK
Max USB/USRP throughput = 32MB/sec
