IM6Q yocto开发平台搭建,学习FREESCALE官方手册笔记
本文文档是freescale手册fsl-yocto-3.14.28-1.0.0.tar.gz的学习笔记,资源以上传到csdn上了,免积分下载.
1.主机环境搭建,各种安装,
(1)安装主机环境,以下部分安装步骤直接摘抄官方
You can go to Yocto Project Quick Start and check for the packages that must be installed for your build machine.
Essential Yocto Project host packages:
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat
i.MX layers host packages for a Ubuntu 12.04 or 14.04 host setup:
$ sudo apt-get install libsdl1.2-dev xterm sed cvs subversion coreutils texi2html \
docbook-utils python-pysqlite2 help2man make gcc g++ desktop-file-utils \
libgl1-mesa-dev libglu1-mesa-dev mercurial autoconf automake groff curl lzop asciidoc
i.MX layers host packages for a Ubuntu 12.04 host setup only:
$ sudo apt-get install uboot-mkimage
i.MX layers host packages for a Ubuntu 14.04 host setup only:
$ sudo apt-get install u-boot-tools
(2)安装repo
官方步骤
To install the “repo” utility, perform these steps:
1. Create a bin folder in the home directory.
$ mkdir ~/bin (this step may not be needed if the bin folder already exists)
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
2. Add the following line to the .bashrc file to ensure that the ~/bin folder is in your PATH variable.
export PATH=~/bin:$PATH
我在使用$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo 时,出现链接超时,因为google被和谐了,暂时没有,只能从其他地方找资源了,使用如下方式,即可,其他步骤不变
$curl "http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo" > ~/bin/repo
(3)Yocto工程安装,步骤直接超手册
Image Build
$mkdir fsl-release-bsp
$cd fsl-release-bsp
$git config --global user.name "Your Name"
$git config --global user.email "Your Email"
$git config --list
$repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.28-1.0.0_ga
$repo sync
以上步骤基本是,顺利安装,如果缺少什么直接按照提示进行apt-get install 就可以了,这一步会耗时比较长.
至此,镜像下载完毕,可以开始平台移植了.
(4)下载你想要的例程对应于文章的第五章 Image Build
根据自己的需要选择你需要的工程例程在5.1节介绍例程简介
我选择 X-11 image on i.MX 6Quad SABRE-SD例程，运行如下语句，即可安装例程，但是时间较长
$ MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11 -e x11
$ bitbake fsl-image-gui
(5)资源目录
在 build-x11/tmp/work/imx6qsabresd-poky-linux-gnueabi 其中＊代表你例程名称，我的例程按照(4)步就为build-x11
