1. Building the meta-chip BSP layer

To get the BSP you need to have repo installed and use it as:

1. Install the repo utility:

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

2. Download the BSP source:

$: PATH=${PATH}:~/bin
$: mkdir chip-bsp
$: cd chip-bsp
$: repo init -u /~https://github.com/texierp/yocto-chip-bsp -b master
$: repo sync

At the end of the commands you have every metadata you need to start work with.

To start a simple image build :

$: cd sources
$: export TEMPLATECONF="$PWD/meta-chip/conf"
$: source poky/oe-init-build-env chip-build

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:
    chip-hwup-image
    meta-toolchain-qt5

You can also run generated qemu images with a command like 'runqemu qemuarm'

2. Flashing a C.H.I.P. board

1. Clone SDK :

$: cd SDK/CHIP-SDK
$ ./setup_ubuntu1404.sh

2. NAND Image creation :

$: ./chip-create-nand-images.sh <patch to>/chip-build/tmp/work/chip-poky-linux-gnueabi/u-boot-chip/2016.01*/git <patch to>/chip-build/tmp/deploy/images/chip/<image>.tar my-chip-image 

3. Flashing (Fastboot) :

$: sudo chown -R username:username my-chip-image/ 
$: sudo ./chip-flash-nand-images.sh my-chip-image/
