1.安装依赖
OpenBMC是基于Yocto搭建的，基于不同的OS预先需要安装的依赖包和工具，清参考：
1 System Requirements — The Yocto Project ® 5.1.999 documentation
2.下载代码
OpenBMC的源码位于：
openbmc/openbmc: OpenBMC Distribution
clone代码：
$ git clone git@github.com:openbmc/openbmc.git3.查看支持的硬件平台
OpenBMC目前已经支持多多种硬件平台，所以编译前需要先选择一个指定的硬件平台
#首先进入clone后的源码目录
$ cd openbmc#查看当前支持的硬件,需要注意.和setup之间有一个空格
$ . setup
Target machine must be specified. Use one of:ahe50dc huygens s7106

4.选择一个硬件平台
$ . setup evb-ast26005.编译
$ bitbake obmc-phosphor-image初次编译时，需要下载所需的源码，因此会很长时间。
如果因为网络原因没有下载成功，再次执行bitbake obmc-phosphor-image编译即可
编译完成后，所生成的image位于目录：openbmc/build/evb-ast2600/tmp/deploy/images/evb-ast2600
