For Ubuntu 14.04 or later revision host setup:

% sudo apt-get install u-boot-tools

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

Download the BSP source:

% PATH=${PATH}:~/bin
% mkdir yocto_project
% cd yocto_project
% repo init -u https://github.com/nutsboard/nutsboard-yocto-bsp-imx.git -b morty-4.9.11
% repo sync

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

To start a X11 based image build for NutsBoard Pistachio:

% cd <local path>/nutsboard-yocto-bsp-imx/
% DISTRO=fsl-imx-x11 MACHINE=imx6qpistachio source nutsboard-setup-release.sh -b build-x11

To start a FB based image build:

% cd <local path>/nutsboard-yocto-bsp-imx/
% DISTRO=fsl-imx-fb MACHINE=imx6qpistachio source nutsboard-setup-release.sh -b build-x11

You must specify which machine is your target at "MACHINE=" argument, and "build-x11" is your path ofbuild folder.

To generate the poky cross compilier environment, it’s easy to use to develop applications.

% bitbake meta-toolchain

To generate the poky image with nutsboard customize meta-layer with qt5 based desktop.

% bitbake fsl-image-qt5-validation-imx

To generate the poky image with nutsboard customize meta-layer with commandline based environment.

% bitbake core-image-minimal

The image elements as follows:

Example - Pistachio

Output Path: <build path>/tmp/deploy/images/almond/

Partition 1: u-boot.imx(MBR), zImage, imx6q-pistachio.dtb, uEnv.txt

Partition 2: fsl-image-qt5-validation-imx-imx6qpistachio-<date>.rootfs.tar.bz2, modules.tgz

SDcard/eMMC image: fsl-image-qt5-validation-imx-imx6qpistachio-<date>.rootfs.sdcard

Installing the toolchain:

Path: <build path>/build/tmp/deploy/sdk/fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-neon-toolchain-4.9.11-1.0.0.sh

After Installtion, please source the environment to auto setting the poky compile environment.

% source environment-setup-cortexa9hf-neon-poky-linux-gnueabi

An application file compile:

% $CC hello.c -o hello

How to add additional packages, for Pistachio, we showing a simple example: Edit <source path>/sources/meta-nutsboard-imx-bsp-release/imx/meta-bsp/conf/machine/imx6qpistachio.conf
