OpenBMC：编译

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 [e-mail]:openbmc/openbmc.git

3.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

4.选择一个硬件平台

$ . setup evb-ast2600

5.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
