OpenWRT on RaspberryPI 2

OpenWRT on RasberryPI 2

build env.

• To build SD card image using Ubuntu 14.04.2 LTS (64-bit)

I: Preparing Ubuntu:

sudo apt-get update
sudo apt-get install git-core build-essential libssl-dev
sudo apt-get install subversion mercurial

II: Download the OpenWRT with git:

git clone git://git.openwrt.org/openwrt.git

• check created a directory 'openwrt'

III: Download and install all available "feeds":

cd openwrt
./scripts/feeds update -a
./scripts/feeds install -a

iV: Make OpenWrt

make defconfig
make prereq
make menuconfig

V: Setup Wi-Fi kernel modules

• select your Wifi USB stick module on config windows

Vi: set component in LuCI->Collections

• select LuCI->Collections

Vii: Save and exit

• select save
• select exit

Viii: build

make -j 3

• if you have some errors. please check message it

make V=s 2>&1 | tee build.log | grep -i error

iX: make SD card

cd openwrt/bin/brcm2708

You will be find "openwrt-brcm2708-bcm2709-sdcard-vfat-ext4.img"

sudo dd if=openwrt-brcm2708-bcm2709-sdcard-vfat-ext4.img of=/dev/sdX bs=2M conv=fsync

• sdX - put your SD card dev (sdb, sdc, ..).

X: start OpenWRT

• Insert SD on Raspberry PI 2
• Connect UART-USB cable
• Insert WiPi stick
• Connect power.
  
  
  Reference Raspberry PI2 GPIO
  
  
  
• Pin#08: TXD0
• Pin#10: RXD0
• Pin#14: GND

Xi: setup new passwd On UART-USB console

passwd

Xii: Reboot Raspberry PI 2 On UART-USB console

reboot

Xiii: Install LuCI On UART-USB console

vi /etc/opkg.conf

• fix opkg.conf file

opkg update
opkg install luci
opkg install luci-ssl
opkg list | grep luci-i18n-
/etc/init.d/uhttpd start
/etc/init.d/uhttpd enable

• WiFi connect to use Access Point

mkdir /etc/wpa_supplicant
vi /etc/wpa_supplicant/wpa_supplicant.conf

• /etc/wpa_supplicant/wpa_supplicant.conf

update_config=1
network={
        ssid="AP name"
        psk="your key"
        scan_ssid=1
        proto=WPA RSN
        key_mgmt=WPA-PSK
        group=CCMP TKIP
        pairwise=CCMP TKIP
        priority=5
}

• Start Wi-Fi connection in background task:

wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf &

• Setting resolving server in /etc/resolv.conf:

vi /etc/resolv.conf

nameserver <put your router IP here>
nameserver 8.8.8.8

• Save file run:

route add default gw <put your router IP here>
