meta-mbed-edge

This README file contains information on the contents of the meta-mbed-edge layer.

This meta-mbed-edge layer contains the Mbed Edge recipe.

This recipe does not contain dependecies to any BSP. For building Mbed Edge on Raspberry Pi 3 there is meta-mbed-raspberrypi layer available.

To add the Mbed Edge to your build, insert following line to your local.conf:

CORE_IMAGE_EXTRA_INSTALL += " mbed-edge "

To set the path to developer certificate file, please set following variable in your local.conf:

MBED_CLOUD_IDENTITY_CERT_FILE = "/path/to/your/mbed_cloud_dev_credentials.c"

To set the path to update resource file, please set following variable in your local.conf

MBED_UPDATE_RESOURCE_FILE = "/path/to/your/update_default_resources.c"

Dependencies

The Mbed Edge is currently tested on top of the morty-version of the Yocto. The following repositories are required for the build:

poky

meta-openembedded

For Raspberry Pi 3 BSP and Mbed Cloud Client firmware update support:

meta-mbed-raspberrypi

Adding the meta-mbed-edge layer to your build

In order to use this layer, you need to make the build system aware of it.

Assuming the meta-mbed-edge layer exists at the top-level of your Yocto build tree, you can add it to the build system by adding the location of the meta-mbed-edge layer to bblayers.conf, along with any other layers needed. e.g.:

  BBLAYERS ?= " \
    /path/to/yocto/meta \
    /path/to/yocto/meta-poky \
    /path/to/yocto/meta-openembedded \
    /path/to/yocto/meta-raspberrypi \
    /path/to/yocto/meta-mbed-raspberrypi \
    /path/to/yocto/meta-mbed-edge \
    "

The BSP support for Raspberry Pi 3 is included in the example above.
