Mission

OpenTina is an open-source community dedicated to providing low-level system software and multi-OS distribution support for the Allwinner A733 chip platform. Our goal is a robust, production-grade software ecosystem: up-to-date board support, mainline kernel integration, and reproducible system build pipelines.

How the project is organized

Everything lives on GitHub under the opentina-org organization:

Code — hardware enablement and BSP components (build, linux, u-boot, trusted-firmware-a, optee_os, awbin, xfel).
Distributions — buildroot, openwrt, meta-opentina, debian, ubuntu.
Documentation — docs for guides and technical references.
Community — the opentina meta-repo hosts the project-wide issue tracker; organization defaults live in .github.

Introduction

Mon, 01 Jan 0001 00:00:00 +0000

OpenTina is an open-source community dedicated to providing low-level system software and multi-OS distribution support for the Allwinner A733 chip platform.

The project aims to build a robust, production-grade software ecosystem for Allwinner A733-based hardware: up-to-date board support, mainline kernel integration, and system build pipelines across embedded Linux, router platforms, and mainstream desktop distributions.
