  1. meta-swupdate, Yocto layer for deploy tool
  2. ==========================================
  3. This layer's purpose is to add support for a deployment
  4. mechanism of Yocto's images based on swupdate project.
  5. Layer dependencies
  6. ------------------
  7. This layer depends on:
  8. URI: git://github.com/openembedded/meta-openembedded.git
  9. subdirectory: meta-oe
  10. Image hashing
  11. -------------
  12. During creation of the update file, occurrences of @IMAGE (where IMAGE is an
  13. image filename) are replaced with the sha256 hash of the image.
  14. SWU image signing
  15. ------------
  16. To enable signing:
  17. Set SWUPDATE_SIGNING = "1"
  18. Set SWUPDATE_PRIVATE_KEY to the full path of private key file
  19. sw-description is signed with the private key and the signature is writen to
  20. sw-description.sig which is included in the SWU file.
  21. Encrypted private keys are not currently supported since a secure
  22. mechanism must exist to provide the passphrase.
