Supported images

To create a custom Linux distribution to match the product requirements, Oniro Project includes a set of predefined images for developing a product image.

Linux Kernel

The Linux kernel is a free and open-source Unix-like operating system (OS) kernel that serves as the primary interface between the computer’s hardware and its processes.

Oniro Project supports the following images listed in the table:

Linux supported images

Image Name	Description
oniro-image-base	Oniro Project image including the base OS software stack. This image also includes middleware and application packages to support a wide range of hardware which includes WiFi, Bluetooth, sound, and serial ports.
oniro-image-extra	Oniro Project Wayland image including the base OS software stack. This is a Wayland protocol and Weston reference compositor-based image. It uses the Wayland protocol and implementation to exchange data with its clients. This image provides the Wayland protocol libraries and the reference Weston compositor and includes a Wayland-capable terminal program.

To build a Linux-based image for a supported machine, see Linux Kernel Build Flavour.

Zephyr Kernel

The Zephyr OS is a well-known security-oriented real-time operating system (RTOS) that is intended for use on resource-constrained and embedded systems.

For more detailed information on Zephyr OS Kernel, see Zephyr documentation.

Oniro Project supports the following images for the Zephyr OS kernel:

Zephyr supported images

Image Name	Description
zephyr-philosophers	A sample Zephyr application implementing the Dining Philosophers problem.

To build a Zephyr-based image for a supported machine, see Zephyr Kernel Build Flavour.

FreeRTOS Kernel

The FreeRTOS kernel is a real-time operating system (RTOS) that runs on a variety of platforms which is used to build microcontroller-based embedded applications.

The standard RTOS kernel binary image ranges from 4000 to 9000 bytes. Oniro Project supports the following images for FreeRTOS Kernel:

FreeRTOS supported images

Image Name	Description
freertos-demo	Machine configuration for running an ARMv5 system on QEMU.
