说明：

我的操作系统环境：ubuntu 14.04 LTS 64位

进入源代码根目录
. build/envsetup.sh(让mmm起作用)
mmm development/tools/idegen/(生成idegen.jar等文件)
sh ./development/tools/idegen/idegen.sh(生成android.irp等文件)
打开android studio导入源码里的android.irp文件(打开Android studio，点击File > Open，选择刚刚生成的android.ipr即可)

其他：
wand 已經 build 好， robotimxsd
先在 wand 上看 run 起來？
follow instruction build idesign.jar
..

bitbake 是用 python 寫的tool
他依照bitbake metadata (.bbclass, .bb) 的task內容，判斷task 的dependency, 安排 build 的順序。

bitbake 安裝完，會有一個 class/base.bbclass , 這是基本的 metadata, 會被所有的 metadata include
所以所有project(/task)共同的部份，可以寫在這裡。

openembedded ..

ref: http://www.openembedded.org/wiki/OE-Core_Standalone_Setup

所以 oe 跟 yocto 根本一樣。

-- 有被proxy 檔的可以改clone github mirror, 有 https : http://www.openembedded.org/wiki/Mirrors

大概就是 clone oe-core, 再到oe-core 下面 clone bitbake.
然後 run envsetup, 指定 build 目錄。
然後就開使用bitbake build

 /oe-core
  |
  +- bitbake
  |
  +- meta(s)
  |
  +- scripts

因為oe-core 自己是一個 git project, 所以bitbake 有被寫進 .gitignore 中。

這一篇有說為什麼： http://stackoverflow.com/questions/35904769/what-are-the-differences-between-open-embedded-core-and-meta-openembedded

At the start of the OpenEmbedded Project, there was only one set of recipes. By 2010, the sheer size of the meta-data was a problem. (You can see the old repository here: https://github.com/openembedded/openembedded) The start of the Yocto Project provided manpower to do something OpenEmbedded had talked about for years, start splitting the recipes into useful and easier to maintain subsets. Openembedded-core are the set of recipes that most people need to use to build a small, useful embedded device. Meta-openembedded was everything else. The meta-openembedded layers are used to extend the capability of openembedded-core by increasing the number of recipes to build more software for your project. Since then, we have been working on meta-openembedded to divide it into smaller groups of recipes grouped by technology, which is why meta-openembedded contains several layers now.

大概是說，openembedded 只有一個 recipts, meta-openembedded 就做openedbedded 沒包到的 recipts
yocto 就利用多 recipts 的方法做出一堆公能。

wandboard, yocto

follow : http://wiki.wandboard.org/Getting_started_with_Yocto_on_Wandboard
但是只能用 dizzy
一樣..

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dizzy
repo sync

然後..

export MACHINE=wandboard-dual
. setup-environment build

會到 build 目錄..

Welcome to Freescale Community BSP

The Yocto Project has extensive documentation about OE including a
reference manual which can be found at:
    http://yoctoproject.org/documentation

For more information about OpenEmbedded see their website:
    http://www.openembedded.org/

You can now run 'bitbake '

Common targets are:
    core-image-minimal
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support

Your configuration files at build have not been touched.
myserver:~/wandyocto/build$ 

然後build.. minimal..

bitbake core-image-minimal

build 好的東西會在..

build/tmp/deploy/images/wandboard-dual/

其中的 core-image-minimal-wandboard-dual.sdcard 就是 sd card image,
直接 dd 到 sd card 就可以。

開機以後，會出現 login prompt, default username=root, 沒有 password

yocto imx6 build log

repo init, repo sync
然後..

DISTRO=fsl=imx-fb MACHINE=imx6qsabreauto source  fsl-setup-release.sh -b build-fb

完成以後，會在 build-fb 目錄..
就在這，下

bitbake fsl-image-gui

然後..
