Build Yocto for Intel Based Platform - ADLINK/meta-adlink-intel GitHub Wiki

1. Set up a build host environment

1.1 Recommended Hardware for the host

  • Intel Core-i7 Processor (>= 4 cores)
  • at least 8GB of Memory
  • at least 500GB Disk sapce
  • Ubuntu 22.04 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-get install gawk wget git diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint xterm zstd liblz4-tool curl git python-is-python3 autoconf nfs-common xutils-dev xsltproc docbook-utils fop dblatex xmlto git-lfs

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

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 intel-yocto-bsp 
$ cd intel-yocto-bsp

2.2 Download the required meta-layers.

It's recommended to use the latest branch and manifest file to build the Yocto image. Here you can find the available branches and manifest files.

kirkstone branch

$ repo init -u https://github.com/ADLINK/adlink-manifest -b intel-yocto-kirkstone -m adlink-x86-bit_v1.1.xml
$ repo sync
$ CONF=adlink source adlink-intel-setup-release.sh -b <build-dir>

scarthgap branch

$ repo init -u https://github.com/ADLINK/adlink-manifest -b intel-yocto-scarthgap -m adlink-x86-bit_v2.0.xml
$ repo sync
$ CONF=adlink source adlink-intel-setup-release.sh -b <build-dir>

Modify the local.conf file as per SEMA controller in your board

Edit the local.conf as below

$ vi conf/local.conf

SEMA - EC Controller

Add the Below line in local.conf and save it 
$ IMAGE_INSTALL:append = " semaec4.0 "

SEMA - TIVA BMC Controller

Add the Below line in local.conf and save it 
$ IMAGE_INSTALL:append = " sema "

2.3 Build the image

$ bitbake core-image-xfce

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

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

3. Flashing the Yocto image
