- meta-swupdate, Yocto layer for deploy tool
- ==========================================
- This layer's purpose is to add support for a deployment
- mechanism of Yocto's images based on swupdate project.
- Layer dependencies
- ------------------
- This layer depends on:
- URI: git://github.com/openembedded/meta-openembedded.git
- subdirectory: meta-oe
- Image hashing
- -------------
- During creation of the update file, occurrences of @IMAGE (where IMAGE is an
- image filename) are replaced with the sha256 hash of the image.
- SWU image signing
- ------------
- To enable signing:
- Set SWUPDATE_SIGNING = "1"
- Set SWUPDATE_PRIVATE_KEY to the full path of private key file
- sw-description is signed with the private key and the signature is writen to
- sw-description.sig which is included in the SWU file.
- Encrypted private keys are not currently supported since a secure
- mechanism must exist to provide the passphrase.
- If SWUPDATE_SIGN_TOOL is set, SWUPDATE_PRIVATE_KEY is ignored and the string
- contained in SWUPDATE_SIGN_TOOL is executed to perform the signing.
