intel-iot-refkit

This README file contains information on setting up, building, and booting the IoT Reference OS Kit for Intel(r) Architecture project.

Only Linux development hosts are currently supported, as documented in the Yocto Project Quick Start Guide

Follow the instructions in this document when trying to get familiar with the IoT Reference OS Kit or when basing a new project on it. Alternatively, it is also possible to take a subset of the content and add it to other, existing projects or distributions. For information about the content, see :file:`doc/introduction.rst`.

Installing Docker on Linux

We recommend you build projects in a Docker container. Using Docker provides a packaged and controlled environment for building an image and can eliminate development environment issues that can occur with differing Linux OS distros and versions, different host compilers, and such. (We also describe building without docker in the instructions below.)

Instructions for installing Docker for common Linux distros on your development machine (including Fedora and Ubuntu) are available at: https://docs.docker.com/engine/installation/linux.

Follow the instructions for your particular distro. You should also perform some of listed Optional Docker Configuration settings:

• Add your Linux user account into the Docker system group with:

  $ sudo gpasswd -a ${USER} docker
  

  You’ll need to log out and back in for this change to take effect.

• Inside company firewalls, you’ll need to configure proxies. Follow the instructions for Docker at https://docs.docker.com/engine/admin/systemd/#http-proxy and also set the usual environment variables:

  $ export http_proxy=http://proxy.example.com:<port>
  $ export https_proxy=https://proxy.example.com:<port>
  $ export ALL_PROXY=socks://proxy.example.com:<port>
  

• Some distributions such as Ubuntu require you to manually configure the DNS server for Docker. This can be done by adding --dns <dns-server-ip-address> to the Docker daemon startup parameters in /etc/default/docker. (Check your /etc/resolv.conf file for system’s specific DNS settings.) More information is available here (note that Ubuntu 15.10 and later use systemd):

  • https://docs.docker.com/engine/admin/configuring/
  • https://docs.docker.com/engine/userguide/networking/configure-dns/

Building with Docker

These instructions assume you’ll be working with the sources in a ~/work/intel-iot-refkit directory that you’ll be creating.

Start by cloning the GitHub repos. If you have a previous copy of this repository without all the submodules, it would be best to remove all the content of workspace directory and clone it again:

$ export WORKSPACE=$HOME/work/intel-iot-refkit
$ mkdir -p $HOME/work
$ cd $HOME/work
$ git clone --recursive https://github.com/intel/intel-iot-refkit.git
$ cd $WORKSPACE

When Docker is configured properly and all project code is cloned and available locally, it's time to trigger a build. To do this run the command from within the ~/work/intel-iot-refkit directory:

Build all pre-configured target images with test suites:

$ docker/local-build.sh

Specify one or more target image(s):

$ docker/local-build.sh refkit-image-common

Building without Docker

While not recommended, you can also use Yocto Project bitbake directly. (Any issues you encounter building this way might not be easily reproducible and debuggable by other developers using a different distribution.)

Here are the basic preparation steps:

$ mkdir -p $HOME/work
$ cd $HOME/work
$ git clone --recursive https://github.com/intel/intel-iot-refkit.git
$ cd intel-iot-refkit
$ source oe-init-build-env

Edit conf/local.conf to select whether to build the production or the development image. More details about the choices in that file.

Basic build steps:

$ bitbake refkit-image-common

Updating Repositories

You may need to pull new content from the GitHub repo as it’s updated. Use the following commands:

$ git pull
$ git submodule update

For more information about Git submodule commands, check this link: https://git-scm.com/docs/git-submodule

Installing the Images

See detailed instructions in how to install images.

Mailing Lists

The project has a mailing list for all project development related discussions.

The mailing list info/subscription page can be found here

Bug Tracking

The project uses the Yocto Project Bugzilla for feature/enhancement and bug tracking.

If you've found a bug or wish to file an enhancement request, go to Bugzilla and submit the tickets against Yocto Project Subprojects | IoT Reference OS Kit component.

Submitting Patches

The project is open to patches and bug fixes. The patches can be submitted as Github Pull requests in https://github.com/intel/intel-iot-refkit or to the project mailing list.

Please follow the common Yocto Project/OpenEmbedded Core Commit Message Guidelines.
