Dependencies

Before running Yocto, install its dependencies with the following command.

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential \
chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping \
libsdl1.2-dev xterm autoconf libtool libglib2.0-dev python-git sed cvs subversion coreutils \

xz-utils debianutils iputils-ping

Setting up Repo tool

Yocto's meta-layers are configured through repo tool, install it as follows.

mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
export PATH=~/bin:$PATH

Getting Source Code

The Yocto's source code is downloaded according to a manifest file that controls Yocto's meta-layers. The repo tool requires a manifest file as an argument to download files, set Yocto as follows.

mkdir imx-yocto-bsp
cd imx-yocto-bsp
BRANCH=imx-linux-morty
MANIFEST=imx-4.9.51-8mq_ga.xml
repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b $BRANCH -m $MANIFEST
repo sync

Set your desired yocto version using the following variables.

Yocto version	Variable	Value
Morty	BRANCH	imx-linux-morty
Morty	MANIFEST	imx-4.9.51-8mq_ga.xml
Rocko	BRANCH	imx-linux-rocko
Rocko	MANIFEST	imx-4.9.88-2.1.0-8mm_alpha.xml

Configuration

Set host's environment variables and create default configuration files by running fsl-setup-release script. Currently (November 2018) only Wayland distro is supported.

BUILD_DIR=build
DISTRO=fsl-imx-wayland MACHINE=imx8mqevk source fsl-setup-release.sh -b $BUILD_DIR

In the first run, DISTRO and MACHINE variables are stored in your default configuration files. In the second (or more) run with the same BUILD_DIR, the environment variables will be loaded from your previous configuration files. In other words, running the previous instructions again with other DISTRO and MACHINE will not change your DISTRO and MACHINE from your default configuration files. If you need to change environment variables from a previous run, you must modify your default files at BUILD_DIR/conf.

Building

Keep in mind that the building can be configured with arguments, check the following tabla for more details.

Option	Description
-c <task>	Execute specific tasks for the image or recipe. Some examples: fetch, compile, clean, cleansstate, package.
-f	Force execution.
-v	Verbose mode.
-DDD	Enable debug information.
-s	Show recipe version.
-g <recipe>	Show dependency tree for the recipe.
-c listtasks <image_or_recipe>	Show the tasks associated with a recipe or image.
-k	keep running if an error appears.
--help	Detailed help information.

In order to build your image, run the next command:

IMAGE=core-image-minimal
OPTION=-k
bitbake $IMAGE $OPTION

Other available images:

fsl-image-multimedia
fsl-image-validation-imx
fsl-image-qt5-validation-imx
fsl-image-multimedia-full

The images will be stored under the directory: <BUILD_DIR>/tmp/deploy/images/imx8mevk

Please refer to Installing an Image section for more information about how to use your image.
