== Compile ==
* https://github.com/openwrt/openwrt
* no need to run it as root
* git clone:
branch openwrt-18.06: git clone -b openwrt-18.06 https://github.com/openwrt/openwrt.git
branch chaos_calmer is legacy: git clone -b chaos_calmer https://github.com/openwrt/openwrt.git
* update
cd openwrt //enter into openwrt folder
./scripts/feeds update -a // update install package
./scripts/feeds install -a //install updates
* '''make menuconfig '''

* '''Predownload: make download'''
* '''Make it - make V=s'''
* '''Make sure do not select buid in kernel or libaries, otherwise firmware image is boo big to be generated!!'''

Via web interface
* Firmware could be updated via LUCI webpage
Via CLI command sysupgrade
* use SCP copy file to openwrt /tmp folder, and run command: sysupgrade -v openwrt-ar71xx-generic-tl-wr842n-v3-squashfs-sysupgrade.bin
* For the following error, run -F to force update:
Invalid image, hardware ID mismatch, hw:07200103 00000001 image:08420003 00000001.
Via CLI command mtd
* '''mtd -r write /tmp/original_firmware.bin firmware'''
* mtd -r write /tmp/original_firmware.bin linux
Via B-boot and TFTP network

* Set PC ethernet ip address to 192.168.1.111 first
* Connect PC and target by ethernet cable
ping 192.168.1.111
setenv serverip 192.168.1.111

== Build and Use Toolchain ==
* in menuconfig, tick option "Build the OpenWrt based Toolchain"
* Toolchain can be found at "/bin/ramips/OpenWrt-Toolchain-ramips-mt7628_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-i686.tar.bz2"
* Install toolchain: sudo tar -jxvf ./bin/ramips/OpenWrt-Toolchain-ramips-mt7628_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-i686.tar.bz2 -C /opt/

== C application ==
* Compile use mipsel-openwrt-linux-gcc
* mipsel-openwrt-linux-gcc hello_world.c -o hello_world
Run the complied application
* chmod +x /tmp/hello_world //add executable rights
* /tmp/hello_world //run“hello_world”application

== System Setup ==
=== Wireless Config /etc/config/wilress ===
<source lang="text">
config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option hwmode '11g'
option path 'platform/10300000.wmac'

option disabled '0'

config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'Electrodragon'
option encryption 'none'
</source>
* After using LUCI config, connect to local AP as openwrt client:

=== Wifi ===
* vi /etc/config/network
Restart network
* #/etc/init.d/network restart
* #ifconfig br-lan

* If error "radio0' is disabled"
uci set wireless.radio0.disabled=0

* Compile to default turn on, and SSID, file at nano ./package/kernel/mac80211/files/lib/wifi/mac80211.sh
set wireless.radio${devidx}.disabled=0
set wireless.default_radio${devidx}.ssid=Electrodragon

* Default wifi configuration find at : vi /etc/config/wireless
=== Reset ===
* firstboot
==== Hardware Remap Reset Pin ====
* [[TL-WR710N]] check the remap settings
* Find openwrt raw definition file at ./target/linux/ar71xx/files/arch/mips/ath79/
* find .|xargs grep -ri "WR710N" to find mach-tl-wr703n.c file which is associated
* Edit

* No need to setup anything for firewall
* Apps list can check on this page [[:category: Linux]]
* Use [[Transmission]]
* change mode to STA-client -> wifi -> find SSID:openwrt -> edit -> mode -> client -> scan -> join network -> enter password -> save
