This layer depends on:

  • URI: git://git.openembedded.org/bitbake

    • branch: master
    • revision: HEAD
  • URI: git://git.openembedded.org/openembedded-core

For usage with Raspberry Pi boards additional layer is required:

  • URI: git://github.com/agherzan/meta-raspberrypi.git
    • branch: master
    • revision: HEAD


The layer contains examples on how to use the SWUpdate project. Examples on how to deploy a "dual-copy" update strategy with some common boards (Beaglebone Black, Raspberry Pi) are provided.

Setup your environment accordingly and update MACHINE to desired target.

To build simply run:

bitbake update-image

Above will generate a swu file suitable for usage with SWUpdate on your device.

Note that update-image depends on ext4.gz and you must make sure that it is part of IMAGE_FSTYPES.

For usage with Raspberry Pi one must add the following to local.conf


Above will enable U-boot which Raspberry Pi does not default to, and instead boots straight to Linux. U-boot is required to do the "swapping" of partitions in the "dual-copy" layout.
