added firmware build information

The following walk through assumes you're using linux and knowledge of terminal. The basic idea of getting a node (router) on the mesh consists of flashing (copying files to the flash) an operating system to node and installing additional drivers and packages. We use [https://openwrt.org/ OpenWRT] as the operating system on our embedded devices (routers), then connect to the node (via [https://en.wikipedia.org/wiki/Secure_Shell SSH]) and install mesh the related software and configure it. The operating system typically fits on 4MB-8MB | |||
=Building an OpenWRT image= | |||
If you already have a image of the operating system (firmware), then you can skip this step. If your router has the stock software, then you'll probably have to use a '''factory image''', which has information in the header which allows you to install it. Otherwise, you'll be using a '''sysupgrade image''' (trx image). | |||
==Step One: Install Buildroot== | |||
The Buildroot is software which will creates your firmware. The Buildroot has feeds associated with it that allow you to add more to your firmware. The feeds are comparable to [https://en.wikipedia.org/wiki/Repository_%28version_control%29 repositories] in linux. There's a [http://wiki.openwrt.org/doc/howto/buildroot.exigence full guide] at OpenWRT, this is a shorter version. | |||
*Install svn and git. | |||
*: <code>$ sudo apt-get install subversion build-essential</code> | |||
*: <code>$ sudo apt-get install git-core</code> | |||
*Make a new directory and download the Buildroot. | |||
*: <code>$ mkdir ~/openwrt</code> | |||
*: <code>$ cd ~/openwrt</code> | |||
*: <code>$ git clone git://git.openwrt.org/openwrt.git</code> | |||
*Update Buildroot and install feeds. | |||
*: <code>$ cd ~/openwrt/openwrtt</code> | |||
*: <code>$ ./scripts/feeds update -a</code> | |||
*: <code>$ ./scripts/feeds install -a</code> (if you want to install all feeds) | |||
