Overview of Project Purpose
===========================

The Yocto Build System is designed to produce a tailored Linux distribution for the embedded platforms. Using Yocto Project and KAS, this system automates the assembly of a custom Linux image that includes hardware support, system services, and applications needed by devices.

Key aspects of the project include:

- **Custom Image for OTTO Platforms:**  
  A Linux image optimized for otto hardware, including bootloader, kernel, and user-space packages specific to the device.

- **Build System (Yocto/KAS):**  
  KAS is used to define and manage the build configuration via YAML files. It sets up the Yocto build environment (Poky, OpenEmbedded layers, etc.) and generates the final image.

- **OTA Updates (SWUpdate):**  
  The distribution supports over-the-air updates using SWUpdate (see *OTA Support* section), allowing devices to receive firmware updates remotely.

- **Container Support (LXC):**  
  The Linux image includes LXC container support (via the meta-virtualization layer) so that additional applications can be deployed in containers.

Project Structure:
------------------

The repository is organized into several directories:

- **distro/**: Distribution and policy configuration.  
- **feature/**: Optional features configuration.  
- **layers/**: Layer definitions (YAML configs referencing layers like Poky, meta-oe, meta-otto, etc.).  
- **machine/**: Machine configuration.  
- **mirror/**: Local mirror configuration.  
- **product/**: Product-specific configurations.  
- **site/**: (Placeholder)  
- **template/**: (Placeholder)  

Refer to the *Layers* and *Configuration* sections for detailed descriptions of each component.
