Prepare build environment
=========================
To make sure the build host is prepared for Yocto running and build, please follow this [guide](https://docs.yoctoproject.org/brief-yoctoprojectqs/index.html) to prepare the build environment. 


Install 'repo' tool
===================
To use this manifest repo, the 'repo' tool must be isntalled first
```
$: mkdir ~/bin
$: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo  > ~/bin/repo
$: chmod a+x ~/bin/repo
$: PATH=${PATH}:~/bin
```

Download Yocto Layers
=====================
The following is the step of how to use repo utility to download all Yocto layers according to the repo manifest. Replace <branch> with the real name (see Yocto branch and version below).

```
$: mkdir yocto-sdk
$: cd yocto-sdk
$: repo init -u https://github.com/nxp-qoriq/yocto-sdk -b <branch>
$: repo sync --force-sync
```

```
Images will be found under tmp/deploy/images/ls2088ardb/.
