Dependencies

This layer depends on:

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

  • branch: master
  • revision: HEAD

• URI: git://git.openembedded.org/openembedded-core

  • branch: master
  • revision: HEAD

or

• URI: git://git.yoctoproject.org/poky
  • branch: master
  • revision: HEAD

and

• URI: git://github.com/sbabic/meta-swupdate.git
  • branch: master
  • revision: HEAD

For usage with Raspberry Pi boards additional layer is required:

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

Usage

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, Sama5d27-som1-ek-sd and Wandboard) 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

RPI_USE_U_BOOT = "1"

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.
