Introduction

About OpenWrt

OpenWrt (http://www.openwrt.org/) is a linux distribution primarily used on embedded devices

to route network traffic. The main components are the Linux kernel, uClibc, busybox, and OpenWrt framework utilities. All components have been optimized for size, to be small enough for fitting into the limited storage and memory available in the routers.

1.2 About this SDK

This SDK is a MTK customized OpenWrt project.

To provide better compatibility and better stability, some OpenWrt drivers were replaced with

MTK drivers, such as Ethernet, USB, WiFi, SD Card, etc.

Build the SDK

Setup Build Environment

To build this SDK, you should have a linux server (linux 2.6.x or later) as the build host.

The default build will take up to 6 GB disk space. Make sure you have enough space to hold it.

Prepare the source project:

tar xjvf mtksdk-openwrt-3.10.14-{date}-{tag}.mini.tar.bz2 -C /path/to/your/workspace

4.2 Check Build Dependency

In the first build, OpenWrt will check your build environment. If it complains that some library or software is missing, you should install them first, eg: yum install svn yum install wget yum install ncurses-devel yum install zlib-devel …..

4.3 SDK root folder

This is what the SDK root folder looks like (Those folder names surrounded with red line are auto generated during build).
