安装

安装SDK2.0， $ sudo mount -o loop QorIQ-SDK-<version>-<target>-<yyyymmdd>-yocto.iso /mnt/cdrom $ /mnt/cdrom/install 安装更新，安装过程中提示输入SDK安装路径， $ tar -xjf SDK-V2.0-1703.tar.bz2 $ ./SDK-V2.0-1703/install

编译

编译输出的镜像文件在build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/中， $ . ./fsl-setup-env -m t2080rdb-64b $ bitbake fsl-image-core 打包内核，根文件系统和设备树， $ bitbake fsl-image-kernelitb

获取软件包源代码

获取u-boot源代码， $ bitbake -c cleansstate u-boot $ bitbake -c patch u-boot 此时可更改源代码并编译， $ bitbake -c compile -f u-boot $ bitbake u-boot 获取内核源代码， $ bitbake -c cleansstate virtual/kernel $ bitbake -c patch virtual/kernel 此时可更改源代码并编译， $ bitbake -c menuconfig virtual/kernel $ bitbake -c compile -f virtual/kernel $ bitbake virtual/kernel 获取软件源代码， $ bitbake usdpaa-apps -c patch -f 此时可更改源代码并编译， $ bitbake -c compile -f usdpaa-apps

定制根文件系统

使用Yocto定制根文件系统，缩小文件系统大小，放入Nor Flash后，加快启动速度， # Copyright (C) 2015 Qe.Ltd require fsl-image-minimal.bb SUMMARY = "Small image commonly used for manufacturing or other small image needs."
