Mender is an open source over-the-air (OTA) software updater for embedded Linux devices. Mender comprises a client running at the embedded device, as well as a server that manages deployments across many devices.

This repository contains Yocto integration layers for various boards.

Please check out https://hub.mender.io for more information on supported boards and instructions on how to setup environment and build images.

This section is for anyone interested in contributing support for a board.

meta-mender-community is a repository containing multiple Yocto layers for integrating Mender onto various boards.

The layers are structured based on upstream BSP layers and not individual boards.

There are multiple types of layers included here.

SoC-oriented:

• meta-amlogic
• meta-freescale
• meta-sunxi
• meta-rockchip
• meta-renesas

Vendor-oriented:

• meta-variscite
• meta-phytec
• meta-toradex-nxp
• meta-mender-octavo-osd32mp

Naming of integration layers follows the upstream naming conventions with SoM vendor layer name having priority. The convention is:

   meta-mender-<upstream suffix>

This should make it clear which layer is targeting what BSP.

The google repo tool and associated manifest files are used for managing the list of repositories needed for these builds. The common manifest (meta-mender-community/scripts/mender.xml) is included by board-specific manifests and include the required Mender layers:

meta-mender-community/scripts/mender.xml

This includes the required Mender layers, meta-mender and meta-mender-community.

Each integration layer should provide a manifest file, e.g

meta-mender-community/meta-mender-sunxi/scripts/manifest-sunxi.xml

To use this layer:

1. Download the source:

    $ mkdir mender-<vendor/soc name>
    $ cd mender-<vendor/soc name>
    $ repo init \
           -u https://github.com/mendersoftware/meta-mender-community \
           -m meta-mender-<vendor/soc name>/scripts/manifest-<vendor/soc name>.xml \
           -b kirkstone
    $ repo sync

2. Setup environment:

    $ . ./setup-environment <vendor/soc name>

3. Build:

    $ bitbake core-image-base

The setup-environment script provided is a wrapper for the Yocto oe-init-build-env script.

Each integration layer must provide:

• local.conf.append: this contains board-specific changes to be appended to the Yocto-generated local.conf file
• bblayers.conf.sample: a template that will be copied to bblayers.conf
• an entry in setup-environment
