1. Set up a build host environment

1.1 Recommended Hardware for the host

  • Intel Core-i7 Processor (>= 8 cores)
  • at least 32GB 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 "imx95-yocto-bsp".

$ mkdir imx95-yocto-bsp 
$ cd imx95-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.

scarthgap branch

$ repo init -u https://github.com/ADLINK/adlink-manifest -b lec-imx-yocto-scarthgap -m adlink-lec-imx95-yocto-scarthgap_1v0.xml
$ repo sync
$ MACHINE=lec-imx95 DISTRO=fsl-imx-xwayland source adlink-imx-setup-release.sh -b <build_dir>

2.3 Build the image

To build with Qt 6 and machine learning, use imx-image-full

$ bitbake imx-image-full

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

2.4 Image is generated as imx-image-full-lec-imx95-*.wic in <build_dir>/tmp/deploy/image/lec-imx95/.
