Compile Menggunakan Development Trunk

Development Trunk tampaknya paling RECOMMENDED

Lakukan sebagai user biasa

svn co svn://svn.openwrt.org/openwrt/trunk/ ~/openwrt.trunk/trunk
cd ~/openwrt.trunk/trunk/
./scripts/feeds update
./scripts/feeds install meshwizard openssh-server openssh-client
./scripts/feeds install freifunk-common freifunk-gwcheck freifunk-mapupdate
./scripts/feeds install luci luci-app-meshwizard luci-app-olsr luci-app-olsr-services
./scripts/feeds install luci-app-olsr-viz luci-app-freifunk-policyrouting luci-mod-freifunk
./scripts/feeds install luci-theme-freifunk-generic olsrd olsrd-mod-txtinfo olsrd-mod-dyn-gw
./scripts/feeds install olsrd-mod-dyn-gw-plain olsrd-mod-dot-draw
./scripts/feeds install olsrd-mod-arprefresh olsrd-mod-watchdog olsrd-mod-tas olsrd-mod-httpinfo

./scripts/feeds install quagga coova-chilli
./scripts/feeds update -a
./scripts/feeds install -a
make clean
make defconfig
make menuconfig
make clean && make -j8 world &

Hasilnya akan berada di folder

~/openwrt.trunk/trunk/bin/ramips/

Konfigurasi Default

Konfigurasi untuk E1700

Target System (Ralink RT288x/RT3xxx) --->
Subtarget (MT7620 based boards) --->
Target Profile (Linksys E1700) --->

Konfigurasi default yang ada dari openwrt tidak ada driver wifi. Kita dapat menambahkan paling tidak

• Luci
• Asterisk (supaya keren)
• Samba (supaya keren)
• UPnP (supaya keren)
• Freifunk _JANGAN_ di install karena membuat masalah di Linksys E1700.

Setelah selesai, kita perlu compile

cd ~/openwrt.trunk/trunk
make clean
make defconfig
make world

Setelah jadi, kita perlu menambahkan driver wifi dan compile ulang secara manual berikut ini.

Cara Menambahkan Driver Wifi

Download patch

cd ~
rm -Rf ~/rt2860v2-for-openwrt-mt7620/
git clone https://github.com/wuqiong/rt2860v2-for-openwrt-mt7620.git

Merge ke build directory

cd ~
cp -r rt2860v2-for-openwrt-mt7620/ralink ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/mtd/

cd ~
cp -r rt2860v2-for-openwrt-mt7620/rt2860v2  rt2860v2-for-openwrt-mt7620/rt2860v2_ap  ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/net/wireless/

Hati-hati folder

/linux-ramips_mt7620/linux-3.14.26
/linux-ramips_mt7620/linux-3.14.27 
/linux-ramips_mt7620/linux-3.14.32
/linux-ramips_mt7620/linux-3.18.7

mungkin akan berubah / berbeda tergantung versi kernel yang kita compile.

Tambahkan di Kconfig dan Makefile

Selanjutnya, tambahkan Kconfig dan Makefile obj di directory "mtd" dan "wireless"

Tambahkan kalimat berikut di akhir file Kconfig sebelum endif #MTD

vi  ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/mtd/Kconfig 

source "drivers/mtd/ralink/Kconfig"
endif # MTD

Tambahkan kalimat berikut di akhir file makefile:

vi ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/mtd/Makefile

obj-$(CONFIG_MTD_RALINK)    += ralink/

Tambahkan kalimat berikut di akhir file Kconfig sebelum endif # WLAN

vi ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/net/wireless/Kconfig 

source "drivers/net/wireless/rt2860v2_ap/Kconfig"
endif # WLAN                      

Tambahkan kalimat berikut di akhir file makefile:

vi ~/openwrt.trunk/trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620/linux-3.18.7/drivers/net/wireless/Makefile 

obj-$(CONFIG_RT2860V2_AP)   += rt2860v2_ap/

Tambahkan konfigurasi

Jalankan

cd ~/openwrt.trunk/trunk
make kernel_menuconfig

Masukan konfigurasi berikut

     System type (Ralink based machines)  --->
     Ralink SoC selection (MT7620/8)  --->

Pastikan pilih (*) untuk membuat driver masuk ke kernel, bukan kernel module.

Buat lagi firmware

Ulangi lagi pembuatan firmware. Tapi

JANGAN LAKUKAN make clean

cd ~/openwrt.trunk/trunk/
make world

Hasilnya ada di folder

~/openwrt.trunk/trunk/bin/ramips

openwrt-ramips-mt7620-e1700-squashfs-factory.bin
openwrt-ramips-mt7620-e1700-squashfs-sysupgrade.bin
openwrt-ramips-mt7620-root.squashfs
openwrt-ramips-mt7620-uImage.bin
openwrt-ramips-mt7620-vmlinux.bin
openwrt-ramips-mt7620-vmlinux.elf

Flash Linksys E1700

Flash image yang di hasilkan ke router. Cara flash yang sederhana menggunakan Web,

• Masuk ke web
• Masuk ke menu system
• Masuk ke menu firmware upgrade
• Pilih file .bin berikut

openwrt-ramips-mt7620-e1700-squashfs-factory.bin

• Flash, jangan sampai listrik mati & sambungan LAN putus.

Device ra0 akan muncul

ifconfig ra0

atau

ifconfig wlan0

Kita tidak bisa mengkonfigurasi

ifconfig ra0 up.

atau

ifconfig wlan0 up

Karena kita tidak memiliki file

/etc/Wireless/RT2860/RT2860.dat

Atau symbol link ke /tmp/RT2860.dat.

File tersebut di buat oleh script di directory /lib/wifi/ yang pertama kali di perkenalkan oleh lintel. Setelah kita mempunyai file

RT2860.dat

Masukan di

/etc/Wireless/RT2860/RT2860.dat
/tmp/RT2860.dat

Agar operasional Linksys E1700 menjadi stabil.

Cara Membuat / Mengambil file RT2860.dat

Cara paling gampang. Download yang sudah jadi

wget https://gitorious.org/wive-rtnl-ralink-rt305x-routers-firmware/wive-rtnl-ralink-rt305x-routers-firmware/raw/a5879610328768271faad102fc0ab80de56ff813:etc/Wireless/RT2860/RT2860.dat

Cara yang lebih susah. Ambil file rt2860v2.sh dari

https://raw.githubusercontent.com/wuqiong/rt2860v2-for-openwrt-mt7620/master/rt2860v2.sh

Untuk MAC address WLAN bisa di set menggunakan file

/etc/config/wireless

dengan parameter

macaddr '1a:1a:1a:1a:1a:1a'

atau menggunakan factory default mac dari eeprom yang dapat diambil menggunakan perintah

hexdump -s 4 -n 6 -C /dev/mtd2 | head -n 1 | sed 's/\ \ /:/g' | cut -d: -f 2 | sed 's/\ /:/g'

Masukan hasil-nya ke parameter di RT2860.dat

MacAddress=

Setelah kita mempunyai file

RT2860.dat

Masukan di

mkdir -p /etc/wireless/RT2860
mkdir -p /etc/Wireless/RT2860
cp RT2860.dat /etc/Wireless/RT2860/RT2860.dat
cp RT2860.dat /etc/wireless/RT2860/RT2860.dat
cp RT2860.dat /tmp/RT2860.dat

Agar operasional Linksys E1700 menjadi stabil.
