Test Ethernet di laptop / PC pastikan kita menggunakan Gigabit Ethernet. Cara men-test dengan menggunakan ethtool 

ethtool eth0

Harus keluar kira-kira seperti di bawah ini 

Settings for eth0: 
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes
	Speed: 1000Mb/s
	Duplex: Full
	Port: Twisted Pair
	PHYAD: 2
	Transceiver: internal
	Auto-negotiation: on
	MDI-X: on
	Supports Wake-on: pumbg
	Wake-on: g
	Current message level: 0x00000007 (7)
			       drv probe link
	Link detected: yes

Pastikan ethernet mampu bekerja pada Gbps.


Set IP address interface ethernet 

ifconfig eth0 192.168.10.1

Cek sambungan ke N210. 

ping 192.168.10.2

HARUS ADA Responds!!! 

PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data.
64 bytes from 192.168.10.2: icmp_req=1 ttl=32 time=1.74 ms

Bagi anda yang menggunakan desktop Ubuntu sebaiknya di set juga dari Network Connection di Desktop agar menjadi IP address statik


Install SDCC

Install sdcc sebaiknya langsung dari file .deb saja. 

wget -c http://launchpadlibrarian.net/38703081/sdcc_2.9.0-5_amd64.deb
wget -c http://launchpadlibrarian.net/38689168/sdcc-libraries_2.9.0-5_all.deb
dpkg -i sdcc_2.9.0-5_amd64.deb sdcc-libraries_2.9.0-5_all.deb

Download Source Code UHD

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

Compile UHD

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 ../

tar -zxf gnuradio-3.4.2.tar.gz
cd gnuradio
patch -p0 < ../usrp52mhz.patch
./configure --enable-gr-uhd --disable-usrp2 --disable-usrp

Perbaiki error: ‘intptr_t’

vi /usr/local/src/gnuradio/gnuradio-core/src/lib/filter/qa_gri_mmse_fir_interpolator_cc.cc

tambahkan 

#include <unistd.h>

Compile GNURadio

cd /usr/local/src/gnuradio
make

ldconfig

Install UHD USRP ke udev

Lakukan 

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

Install Image 003.005.000

Download Image UHD 003.005.000 

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

Images successfully installed to: /usr/local/share/uhd/images

Burn ke N210, pastikan kita terhubung ke N210 & N210 dalam keadaan operasinal. Lakukan, 

/usr/local/bin/usrp_n2xx_simple_net_burner --addr="192.168.10.2"
