1. Set up a build host environment

1.1 Recommended Hardware for the host

  • Intel Core-i7 Processor (>= 16 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-get install gawk wget git-core 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

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 start 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 "mtk-yocto-bsp".

$ mkdir mtk-yocto-bsp 
$ cd mtk-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 rity-scarthgap-v25.1 -m osm-mtkX-25.1.xml
$ repo sync
$ source setup_adlink_env.sh -b <build_dir> -m osm-mtk510

Required Setting in conf/local.conf to build the image with the MediaTek NDA Yocto recipes.

$ vi <build_dir>/conf/local.conf
NDA_BUILD = "1"

Please set up your machine configuration to support build NDA related recipes , check/follow the link for further instructions NDA

2.4 Build the image

$ bitbake rity-demo-image

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

2.5 Image is generated in <build_dir>/tmp/deploy/image/osm-mtk510/.
