Yocto Project Setup on i.MX 6Quad SABRE-SD

2018-03-28

1. Setting Up Host Machine Packages

My host machine is Red Hat 4.8.2-16, Linux version 3.10.0-123.20.1.el7.x86_64 (官方推荐存储不少于120G)

Go to Yocto Project Quick Start and check for the packages that must be installed on the host machine

2. Set Up The Repo Utility

2.1 Create a bin folder in the home directory

 mkdir ~/bin
 curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
 chmod a+x ~/bin/repo

2.2 Add the following line to the .bashrc file

export PATH=~/bin:$PATH

3. Download Yocto Project

git config --global user.name zhangsan
git config --global user.email zhangsan@163.com
git config --list 
mkdir fsl-release-bsp
cd fsl-release-bsp
repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-morty -m imx-4.9.11-1.0.0_ga.xml
repo sync

等待同步完成，同步过程出错，可以用ctrl+c中断，然后执行repo sync继续同步。

4. Build Image:

DISTRO=fsl-imx-x11 MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11
bitbake fsl-image-validation-imx

4.1 其中DISTRO有如下四种设置：
• fsl-imx-x11 : Only X11 graphics
• fsl-imx-wayland : Wayland weston graphics
• fsl-imx-xwayland : Wayland graphics and X11. X11 applications using EGL are not supported
• fsl-imx-fb : Frame Buffer graphics - no X11 or Wayland

4.2 MACHINE指的是板子的型号

4.3 -b 跟的是安装目录

4.4 bitbake可以编译以下多种镜像：
• core-image-minimal
• core-image-base
• core-image-sato
• fsl-image-machine-test
• fsl-image-validation-imx
• fsl-image-validation-qt5-imx

bitbake的时间非常长，如果编译中途出错，可以用ctrl+c中断，然后重新执行

bitbake fsl-image-validation-imx

如果编译过程中关掉终端，可以重新进入fsl-release-bsp文件夹，先执行

source setup-environment build-x11

然后执行

bitbake fsl-image-validation-imx

4. Image

编译成功后，在 ~/fsl-release-bsp/build-x11/tmp/deploy/images/imx6qsabresd 文件夹下存在如下文件：
fsl-image-validation-imx-imx6qsabresd-20180323140502.rootfs.ext4
