1.1 Recommended Hardware for the host
- Intel Core-i7 Processor (>= 4 cores)
- at least 8GB 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-python3Note: 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}:~/bin1.4 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 --list2.1 Create a working directory. we're creating "imx8mp-yocto-bsp".
$ mkdir imx8mp-yocto-bsp
$ cd imx8mp-yocto-bsp2.2 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.
For instance kirkstone branch
$ repo init -u https://github.com/ADLINK/adlink-manifest.git -b sp2-imx-yocto-kirkstone -m adlink-sp2-imx8mp-yocto-kirkstone_5.15.71-2.2.0_desktop.xml
$ repo syncFor instance scarthgap branch
$ repo init -u https://github.com/ADLINK/adlink-manifest.git -b sp2-imx-yocto-scarthgap -m adlink-sp2-imx8mp-yocto-scarthgap_6.6.23-2.0.0.xml
$ repo sync2.2.1 cherry-pick some recipes in the meta-openembedded meta-layer (For kirkstone only)
$ cd sources/meta-openembedded/

for kirkstone build:
To build nxp-desktop image without Time Sensitive Network Support, use imx-image-desktop
$ bitbake imx-image-desktopfor scarthgap build: To build imx-image-full image
$ bitbake imx-image-fullNote: Sometimes the build may fail due to the traffic/server try again after sometime
2.5 Image is generated
for kirkstone build:
as imx-image-desktop-sp2-imx8mp.rootfs.wic in <build_dir>/tmp/deploy/image/sp2-imx8mp/.
for scarthgap build:
as imx-image-full-sp2-imx8mp.rootfs.wic in <build_dir>/tmp/deploy/image/sp2-imx8mp/.
