Build Yocto for AMD Based Platform

1. Set up a build host environment

1.1 Recommended Hardware for the host

• Intel Core-i7 Processor (>= 4 cores)
• at least 16GB of Memory
• at least 500GB Disk sapce
• Ubuntu 20.04 LTS 64-bit version for Yocto Project Build
• High-speed network connectivity

1.2 Essential host Packages are required to be installed on your host

$ sudo apt install -y gawk wget git diffstat unzip texinfo gcc \
     build-essential chrpath socat cpio python3 python3-pip \
     python3-pexpect xz-utils debianutils iputils-ping python3-git \
     python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 xterm \
     python3-subunit mesa-common-dev

Note: Don't use the root account to build Yocto. it might cause unpredictable errors.

1.3 "Google repo" packages is required to be installed on your host

$ mkdir ~/bin (this step may not be needed if the bin folder already exists)
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ export PATH=${PATH}:~/bin
$ export LC_ALL="en_US.UTF-8"

1.4 Before star to build the source, please make sure that git is set up properly with the commands below

$ git config --global user.name "Your Name"
$ git config --global user.email "Your Email"
$ git config --list

2. Fetch the source from the git location as below

2.1 Create a working directory. we're creating "intel-yocto-bsp".

$ mkdir amd-yocto-bsp 
$ cd amd-yocto-bsp

2.2 Download the required meta-layers.

kirkstone branch

$ repo init -u https://github.com/ADLINK/adlink-manifest -b amd-yocto-kirkstone -m adlink-x86-amd.xml
$ repo sync
$ CONF=adlink MACHINE=V3000  source adlink-amd-setup-release.sh -b <build-dir>

scarthgap branch

$ repo init -u https://github.com/ADLINK/adlink-manifest -b amd-yocto-scarthgap -m adlink-x86-amd.xml
$ repo sync
$ CONF=adlink MACHINE=V3000  source adlink-amd-setup-release.sh -b <build-dir>

2.3 Build the image

$ bitbake core-image-sato

Note: Sometimes the build may fail due to the traffic/server try again after sometime

2.5 Image is generated as core-image-sato.wic in <build_dir>/tmp/deploy/image/.

3. Flashing the Yocto image
