The core-image-base image recipe provides a runtime environment with basic system utilities, networking support, SSH access, and commonly used tools. This image is a good starting point for embedded Linux systems that require essential functionality without a full graphical user interface. It’s provided by meta layer of Poky and appended by meta-digi-dey layer to include basic Digi Embedded Yocto features.

The default installer for ConnectCore 93 Development Kit includes the Core image base demo. If you followed the Get Started process, your target already contains the Core image base demo and you can skip this topic.
