i.MX6 Yocto工程简介与分析
i.MX6Yocto工程简介与分析
按照NXP官方网站的说法，i.MX6的源码都发布在Yocto Project Freescale i.MX6 release工程里了。The FSL Yocto Project Community BSP (freescale.github.io)是一个社区驱动的在Yocto Project里提供相关i.MX6单板支持和维BoardSupport Packagemetalayer社区。使用OpenEmbedded-Core 和 Poky Yocto版本，提供如下主要3个主要meta layer：
meta-freescale: 提供基本BSP支持。
meta-freescale-3rdparty: 第三方和合作伙伴板级支持。
meta-freescale-distro: 提供和版本发布、包管理相关的支持。
该社区最近发布的版本为2.0版本Jethro(对于imx-4.0)、2.1版本Krogoth (对于imx-4.1)和2.2版本Morty (对于imx-4.2)。我们选用imx-4.1.15-2.0.0这个稳定分支。
1、YoctoProject简介
术语 yocto 是最小的SI 单元。作为一个前缀，yocto表示10^-24。YoctoProject是一个开源的协作软件，提供模板、工具和方法帮你创建定制的 Linux 系统和嵌入式产品，而无需关心硬件体系，支持ARM, PPC, MIPS,x86 (32 & 64 bit)硬件体系架构。适合嵌入式Linux开发人员使用。查看Yocto Project Quick Start。
在整个Yocto Project中，这些部分被称为项目，包括构建工具、称为核心配方的构建指令元数据、库、实用程序和图形用户界面 (GUI)。
Poky是YoctoProject的参考发布版本。它包括OpenEmbedded构建系统(BitBake and OpenEmbedded Core)和一系列metadata，帮助开发者构建自己的distro。Poky 这一名称也指使用参考构建系统得到的默认 Linux 发行版，它可能极其小 (core-image-minimal)，也可能是带有 GUI 的整个Linux 系统 (core-image-sato)，它是一个关于搭建编译你自己制定的Linux发布版本的一个源代码用例。
BitBake 是一个构建引擎，像所有的build工具一样(比如make，ant，jam)控制如何去构建系统并且解决构建依赖。BitBake不是基于固定依赖关系的makefile，而是收集和管理大量没有依赖关系的描述文件(称为包的配方recipes)，然后自动按照正确的顺序进行构建。它读取recipes配方并通过获取程序包来密切关注它们、构建它们并将结果纳入可引导映像。BitBake 由 Yocto Project 和OpenEmbedded 项目共同维护。
OpenEmbedded，简称OE，它用来构建和管理嵌入式开发系统（交叉编译、安装、打包）。2004年10月7日ChrisLarson把OE分成了两个项目。一个是BitBake（构建任务的执行者），一个是OpenEmbedded（实际上是为BitBake提供元数据）。YoctoProject使用的OE称为OpenEmbedded-Core，是一些脚本(shell和Python脚本)和用来交叉编译、安装和打包的metadata(元数据)构成的自动构建系统。
metadata元数据集按层进行排列，每一层都可以为下面的层提供单独的功能。基层是 OpenEmbedded-Core 或oe-core，提供了所有构建项目所必需的常见配方、类和相关功能。然后可以通过在 oe-core 之上添加新层来定制构建。OpenEmbedded-Core 由Yocto Project 和 OpenEmbedded 项目共同维护。将 Yocto Project 与 OpenEmbedded 分开的层是meta-yocto 层，该层提供了 Poky 发行版配置和一组核心的参考 BSP。
metadata元数据集包含如下部分：
recipes(配方)：(.bb/.bbappend)组件的逻辑单元的构建规范，用来获取源代码、构建和打包组件；
class：(.bbclass)包括各个recipes之间共享的相同的功能；
configuration：(.conf)定义Poky如何的各种配置文件；
layers：一系列相同的recipes，就像meta-fsl-arm。
板卡支持包BSP含为特定板卡或架构构建 Linux 必备的基本程序包和驱动程序。这通常由生产板卡的硬件制造商维护。
2、Freescalei.MX6 Yocto Project搭建
a)基本软硬件环境要求
虽然按照《i.MX Yocto Project User's Guide》中所说Ubuntu 12.04和14.04版本均可，但是为了以后升级和维护的便利，强烈建议使用14.04版本！内存要2G以上(注意不是包括2G，因为内存太小编译可能有问题)，磁盘空间至少80G以上，推荐120G，CPU至少双核。强烈不推荐虚拟机的方式，直接在硬盘上安装Ubuntu，除非你的磁盘性能很高。
b)建立Ubuntu 14.04所需要的包
建立Ubuntu 14.04开发包之前，最好把Ubuntu在SoftwareUpdater里更新到最新。
sudo apt-get update
sudo apt-get install gawk wget git-corediffstat unzip texinfo gcc-multilib \
build-essential chrpath socatlibsdl1.2-dev
sudo apt-get install libsdl1.2-devxterm sed cvs subversion coreutils texi2html \
docbook-utils python-pysqlite2 help2manmake gcc g++ desktop-file-utils \
libgl1-mesa-dev libglu1-mesa-devmercurial autoconf automake groff curl lzop asciidoc
sudo apt-get install u-boot-tools
c)下载repo
mkdir ~/bin (this step may not beneeded if the bin folder already exists)
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo> ~/bin/repo
参考文档1给出的地址需要才能下载，所以换个地址：
curlhttp://php.webtutor.pl/en/wp-content/uploads/2011/09/repo > ~/bin/repo
chmod a+x ~/bin/repo
vi ~/.bashrc 在尾部加：
export PATH=~/bin:$PATH
d)配置git
git config --global user.name"Your Name"
git config --global user.email"Your Email"
git config --list
e) Yocto Project Setup
cd ~
mkdir imx6 && cd imx6
mkdir fsl-release-bsp && cdfsl-release-bsp
repo init -ugit://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth –m imx-4.1.15-2.0.0.xml --repo-url=https://gerrit-google.tuna.tsinghua.edu.cn/git-repo
//repo可能找不到，export PATH=~/bin:$PATH下，要是不行，可使用Ubuntu的提示：sudo apt-get installphablet-tools
repo sync //时间可能比较长，依赖于你的网络。
3、ImageBuild
a)Build configurations
Freescale提供了一个脚本fsl-setup-release.sh，能大大简化构建配置。
DISTRO=
fsl-imx-x11 只支持X11 graphics
fsl-imx-wayland 只支持Waylandweston graphics
fsl-imx-xwayland 支持 Waylandgraphics 和X11
fsl-imx-fb 只支持Frame Buffer graphics ，不支持X11和Wayland
imx23evk
imx28evk

imx7d19x19lpddr2arm2
imx7d19x19lpddr3arm2
imx7dsabresd
ls1021atwr
twr-vf65gs10
当执行该脚本之后，会在
每次新打开一个窗口，都要进行一次source操作。
#sourcesetup-environment
我们使用的是
DISTRO=fsl-imx-x11 MACHINE= imx6qsabresd source fsl-setup-release.sh–b build-x11
b)选择一个镜像编译
可供选择的镜像名字如下表格：
Image name
Target
Provided by layer
core-image-minimal
A small image that only allows a device to boot.
poky
core-image-base
A console-only image that fully supports the target device hardware.
poky
core-image-sato
An image with Sato, a mobile environment and visual style for mobile devices. The image supports X11 with a Sato theme and uses Pimlico applications. It contains a terminal, an editor and a file manager.
poky
fsl-image-machine-test
An FSL Community i.MX core image with console environment - no GUI interface.
meta-fsl-demos
fsl-image-gui
Builds a Freescale image with a GUI without any Qt content.
meta-fsl-bsp-release/imx/meta-sdk
fsl-image-qt5
Builds an opensource Qt 5 image. These images are only supported for i.MX SoC with hardware graphics. They are not supported on the i.MX 6UltraLite, i.MX 6UltraLiteLite,and i.MX 7Dual.
meta-fsl-bsp-release/imx/meta-sdk
我们一般使用core-image-base和fsl-image-gui吧。
c)编译镜像
bitbake image-name
我们使用的是bitbake fsl-image-gui
然后漫长的等待，因为要下载7000+个源码包，并把它们编译完全。

5、可能存在的问题
(1) bitbake编译时提示在TMPDIR或SSTATE_DIR创建一个长名文件失败
x@x:~/imx6/fsl-release-bsp/build-x11$ bitbake fsl-image-gui
NOTE: Your conf/bblayers.conf has been automatically updated.
ERROR: OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker(see sanity.conf).
Following is the list of potential problems / advisories:
Failed to create a file with a long name in TMPDIR. Please use afilesystem that does not unreasonably limit filename length.
Failed to create a file with a long name in SSTATE_DIR. Please use afilesystem that does not unreasonably limit filename length.
问题可能原因：# Check thatTMPDIR isn't on a filesystem with limited filename length (eg. eCryptFS)
解决方法：把用户目录去掉加密。
去掉加密步骤：
1)、备份主目录 sudo cp -rp /home/x /home/xx
2)、启动root登录，sudo passwd
3)、root登录进去新建一个账号z，useradd z //注意不用创建目录
4)、重启系统，用z账号shell登录进去，然后su切换到root账号
5)、root账号下删除x用户目录 rm -rf /home/x
在root用户下删除主目录时失败，提示的资源文件忙，这时重启一下机器用root用户登录系统，在删除就没有问题了。
6)、重命名备份主目录xx为主目录x：mv /home/xx /home/x
7)、root账号下删除加密文件
rm -rf /home/.ecryptfs
rm -rf /home/x/.ecryptfs
rm -rf /home/x/.Private
8)、账号x下取消root账号登录：sudo passwd -l root
9)、账号x下删除z账号：sudo userdel -rf z
