Add image recipes

Provides information on how to add image recipes and build using BitBake command.

​

Image recipe concepts

An image recipe (.bb file) defines the complete set of packages installed in the root filesystem. Qualcomm provides reference images in meta-qcom-distro/recipes-products/images. For a description of each reference image, see meta-qcom-distro.

Creating a custom image recipe

1. To add an image recipe, change the directory to <workspace>/layers/meta-qcom-distro/recipes-products/images.
2. Create a file, for example sample-image.bb, and add the following content:
   require qcom-minimal-image.bb
   
   SUMMARY = "Basic sample image"
   
   IMAGE_FEATURES += "${@bb.utils.contains('DISTRO_FEATURES', 'sota', '', 'package-management', d)} \
                       ssh-server-openssh"
   
   CORE_IMAGE_BASE_INSTALL += " \
      packagegroup-qcom-security \
      packagegroup-qcom-utilities-debug-utils \
      packagegroup-qcom-utilities-network-utils \
      packagegroup-qcom-utilities-profile-utils \
      packagegroup-qcom-utilities-support-utils \
   "
   
3. Add the sample-image.bb file to the meta-qcom/ci/qcom-distro.yml CI file, under target::
   target:
      - qcom-multimedia-image
      - qcom-multimedia-proprietary-image
      - qcom-container-orchestration-image
      - sample-image
   
4. Source the environment:
   kas shell meta-qcom/ci/rb3gen2-core-kit.yml:meta-qcom/ci/qcom-distro.yml
   
5. Build using the BitBake command:
   bitbake sample-image
   
   The generated images are as follows:
   build> $ ls tmp/deploy/images/rb3gen2-core-kit/sample-image.qcomflash/
