5.9.2.4. Operational Modes

You can use Wic in two different modes, depending on how much control you need for specifying the Openembedded build artifacts that are used for creating the image: Raw and Cooked:

Regardless of the mode you use, you need to have the build artifacts ready and available. Additionally, the environment must be set up using the oe-init-build-env or oe-init-build-env-memres script found in the Build Directory.
