Depending upon your firmware update strategy, you can create a software update (SWU) package in different ways. To learn about the characteristics of SWU packages based on system images, see SWU packages based on system images.
To build a SWU package based on system images, use the following command from your project’s directory:
$ bitbake dey-image-webkit-swu
This generates the update package under
Make sure you have not declared
SWUPDATE_RDIFF_ROOTFS_SOURCE_FILE variables in your project.
Otherwise, the resulting image from the above operation will be a SWU package based on files or differences rather than a SWU package based on images.
