# 1. Setting up the build system Building images for AMD BSPs requires setting up the Yocto Project Build System. Please follow the guidelines on [Yocto Project Overview and Concepts Manual](https://www.yoctoproject.org/docs/2.7.1/overview-manual/overview-manual.html) and [Yocto Project Quick Build Guide](https://www.yoctoproject.org/docs/2.7.1/brief-yoctoprojectqs/brief-yoctoprojectqs.html) if you are not familiar with the Yocto Project and it's Build System. Running the following commands will setup the build system and will enable us to build recipes & images for any of the supported AMD BSPs (i.e `r1000`, `v1000` or `e3000`). ### 1.1 Prerequisites Install the build system's dependencies: ```sh sudo apt install -y gawk wget git-core diffstat unzip texinfo \ gcc-multilib build-essential chrpath socat cpio python python3 \ python3-pip python3-pexpect xz-utils debianutils iputils-ping \ python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev xterm ``` ### 1.2 Download the build system and the meta-data layers Select the Yocto Project branch: ```sh YOCTO_BRANCH="warrior" ``` Clone the git repositories: ```sh git clone --single-branch --branch "${YOCTO_BRANCH}" \ "git://git.yoctoproject.org/poky" "poky-amd" cd poky-amd git clone --single-branch --branch "${YOCTO_BRANCH}" \ "git://git.openembedded.org/meta-openembedded" git clone --single-branch --branch "${YOCTO_BRANCH}" \ "git://git.yoctoproject.org/meta-dpdk" git clone --single-branch --branch "${YOCTO_BRANCH}" \ "git://git.yoctoproject.org/meta-amd" ``` Checkout commit hashes: ```sh git checkout --quiet 79a850a10a4b88a6d20d607b322542f947874323 cd meta-openembedded git checkout --quiet f4ccdf2bc3fe4f00778629088baab840c868e36b cd ../meta-dpdk git checkout --quiet c8c30c2c4e2f36b4a55a69a475fe774015423705 cd ../meta-amd git checkout --quiet tags/warrior-v1000-ga-201912 cd .. ``` --- #### What's next Continue to "Section 2 - Setting up and starting a build" ([BUILD.md](BUILD.md)) for instructions on how to setup and start a build for a particular AMD BSP.
