===== Build Firmware =====

To build firmware you need **Ubuntu 16.04 LTS**, other distributions may work but are not supported. For example, Ubuntu 20.04 is known to not work. Building firmware directly on a Windows platform is not supported. However, if all you have available is a Windows machine then we would recommend to set up a Linux based virtual machine. 

//Note: the following build was made on Ubuntu 16.04.7 LTS running 4.4 kernel.//

//Note: please build with non-root privileges!//

----

Once you have a Linux OS running install the following prerequisite packages:

  sudo apt-get update
  sudo apt-get install git git-doc subversion build-essential flex wget gawk unzip man file python2.7 zlib1g-dev libssl-dev libncurses5-dev ocaml-nox

\\
Get latest sources from 8devices OpenWrt branch:

  git clone --branch qsdk-11.3-ipq60xx-4.4 https://github.com/8devices/openwrt-8devices.git
  cd openwrt-8devices

\\
The easiest way is simply to execute a build script and wait until firmware will be built. 

  ./quick_start.sh 8dev_mango_open  -c

\\
Building is a CPU heavy process and may take a long time depending on your CPU capabilities. 

Once finished the compiled firmware image ending with ''openwrt-ipq-ipq60xx-8devices-mango-dvk-squashfs-sysupgrade.bin'' will be placed under ''/bin/ipq/'' directory.
