Package Content

==

1. bootstrap/ :

  The bootstrap/ directory contains build tools to construct a bootstrap system for ezbox.

  The major part of build tools is from openwrt project(https://dev.openwrt.org/wiki)

2. distro/ :

  The distro/ directory contains distribution-related packages.

  Each distribution has its own purpose, and contains different packages.

3. misc/ :

  This directory stores a lot of nothing, may be removed :-)

4. realtime/ :

  This directory contains real-time patches for Linux kernel.

5. scripts/ :

  This directory contains scripts used by building system.

==

Quick Start

==

  The ezbox sample build is a kuafu distro on ar71xx board.

1. Copy the default.mk.sample to BASE_DIR

	cp default.mk.sample ../default.mk

2. Start to build the kuafu distro

	make kuafu

3. Check the build log in BASE_DIR

	cat ../XXX-kuafu-ar71xx-build.log

==

Build Instructions

==

1. Before building the target system for ezbox, you should select a distro and symbol link the target arch to bootstrap/target/linux directory. Following examples will use distro kuafu and target CPU is ar7240.

	1) Copy bootstrap system source tree to a working directory

		rm -rf bootstrap.ar71xx

		cp -af bootstrap bootstrap.ar71xx

	2) Symbol link target

		ln -s `pwd`/distro/kuafu/target/linux/ar71xx bootstrap.ar71xx/target/linux/ar71xx

	3) Use distro default packages

		cp distro/kuafu/feeds.conf bootstrap.ar71xx/feeds.conf

	4) Use default config for the target distro

		cp distro/kuafu/configs/defconfig-ar71xx bootstrap.ar71xx/.config

2. Set environment variables

	1) Set target device type

		export DEVICE_TYPE=ezbox

	2) Set target arch

		export ARCH=mips

3. Enter working directory and start build

	1) Goto bootstrap.ar71xx/ directory

		cd bootstrap.ar71xx/

	2) Get target distro default packages

		./scripts/feeds update -a

	3) Install all target distro default packages

		./scripts/feeds install -a

	4) Generate fresh config file

		make ARCH=mips oldconfig

	5) Start build, and record output to build.txt

		make DEVICE_TYPE=ezbox V=99 2>&1 | tee build.log

==

CPU Architecture Settings.

==

1. ar71xx

	export ARCH=mips

2. brcm47xx

	export ARCH=mipsel

3. x86

	export ARCH=i386

==

Known issues

==

1. Please set LD_LIBRARY_PATH if it can't find correct libraries for building host tools.

  $ export LD_LIBRARY_PATH="/path/to/your/staging/host/lib:$LD_LIBRARY_PATH"
