  • Multiple layers (In submodules)
  • Easy to use (Makefile)

How to use docker-yocto

Clone this repository

git clone --recurse-submodules --remote-submodules https://github.com/bensuperpc/docker-yocto.git

Checkout the branch you want (For each submodules/layers). All branches must be the same version on poky/openembedded-core and other submodules/layers.

git branch -a # show all branches on submodules/layers or poky/openembedded-core
git checkout -t origin/langdale -b my-langdale # checkout the branch and create a new branch

Build with docker

make build

Start the container

Now you can start the container, it will mount the current directory in the container.

make start

Build with yocto

Now you are in the container, you can build image with yocto. Initialize the Build Environment, it will create a build directory.

With openembedded-core :

source openembedded-core/oe-init-build-env build_x86_64

Or with poky (Not for production) :

source poky/oe-init-build-env build_x86_64

Add meta-intel layer :

bitbake-layers add-layer ../../meta-intel

Show layers if you want :

bitbake-layers show-layers

Change the MACHINE in conf/local.conf :

MACHINE = "intel-corei7-64"

Now you can build the image :

bitbake core-image-full-cmdline

Now you can exit the container when the build is finished.

exit

All the build is in the "builds" directory.

Update submodules and base debian image

make update
