Snappy Layer for Artik BSP

Prepare enviroment

• On ubuntu 14.04

If you're using ubuntu 14.04, you need to build snapcraft first. Please follow the below document to add snapcraft. https://github.com/walimis/meta-snappy-tools/blob/master/README.md

• On ubuntu 16.04

Install snappy tools

$ sudo apt-get update
$ sudo apt-get install snapd snapcraft

Get poky and snappy common layer

• Clone poky

$ apt-get install build-essential chrpath texinfo diffstat python-minimal
$ export POKY=<path>
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git checkout -b krogoth origin/krogoth (or simply git checkout krogoth)
$ cd ..

• Clone snappy layer

$ git clone https://github.com/walimis/meta-snappy.git

Get artik bsp as example

• Clone artik bsp layer

$ git clone https://github.com/resin-os/meta-artik

• Clone snappy layer for artik bsp

$ git clone https://github.com/walimis/meta-artik-snappy.git

Build snappy image

• Prepare bitbake

$ cd $POKY
$ source poky/oe-init-build-env
$ cd build/ (the above command should have brought you to the build directory)

$ vim conf/bblayers.conf

Add ${POKY}/meta-artik
Add ${POKY}/meta-snappy
Add ${POKY}/meta-artik-snappy
to BBLAYERS, replase ${POKY} to real path.

$ vim conf/local.conf
Replace “MACHINE” with:
MACHINE ??= "artik10"

• Build kernel snap

Before generate kernel snap, we need run "snapcraft login" to create credentials for snapcraft.

$ snapcraft login

Now run bitbake to generate kernel snap

$ bitbake linux-yocto-artik -c kernel_snap
(Wait long time for task finish)

$ bitbake linux-yocto-artik
$ ls tmp/work/artik10-poky-linux-gnueabi/linux-yocto-artik/3.10.9+gitAUTOINC+84a5d7636d-r0/image/kernel.snap

• Build gadget snap

$ bitbake artik-gadget-snap -c gadget_snap
$ bitbake artik-gadget-snap
$ ls tmp/work/cortexa15hf-neon-poky-linux-gnueabi/artik-gadget-snap/1.0-r0/image/gadget.snap
