This repository provides Repo manifests to setup the Yocto build system for supported Xilinx products.
The Yocto Project allows the creation of custom linux distributions for embedded systems, including Xilinx-based systems. It is a collection of git repositories known as layers each of which provides recipes to build software packages as well as configuration information.
Repo is a tool that enables the management of many git repositories given a single manifest file. Tell repo to fetch a manifest from this repository and it will fetch the git repositories specified in the manifest and, by doing so, setup a Yocto Project build environment for you!
1. Install Repo.
Download the Repo script:
$ curl https://storage.googleapis.com/git-repo-downloads/repo > repo
Make it executable:
$ chmod a+x repo
Move it on to your system path:
$ sudo mv repo /usr/local/bin/
If it is correctly installed, you should see a Usage message when invoked with the help flag.
$ repo --help
2. Initialize a Repo client.
Create an empty directory to hold your working files:
$ XILINX_SOURCES=/path/to/xilinx/sources
$ mkdir -p $XILINX_SOURCES
$ cd $XILINX_SOURCES
To test out the release branch type:
$ repo init -u git://github.com/Xilinx/yocto-manifests.git -b rel-v2017.3
$ repo sync
A successful initialization will end with a message stating that Repo is initialized in your working directory. Your directory should now contain a .repo directory where repo control files such as the manifest are stored but you should not need to touch this directory.

3. Fetch all the repositories:
$ repo sync
Now go turn on the coffee machine as this may take 20 minutes depending on your connection.
To pick up the latest changes for all source repositories, run:
$ repo sync
Sooner or later, you'll want to customize the Repo manifest to point at different repositories and branches or pull in additional meta-layers.
Clone this repository (or fork it on github):
$ git clone git://github.com/Xilinx/yocto-manifests.git
Make your changes (and contribute them back if they are generally useful), and then re-initialize your repo client
$ repo init -u <file:///path/to/your/git/repository.git>
