System images

Recommended for beginners

We strongly recommend that new users download the GPT-format Radxa OS official image and flash it to a microSD card with Balena Etcher. This is the simplest and fastest way to get started.

Image type notes

• GPT system image (recommended for beginners):

  • Works with microSD cards or NVMe SSDs
  • Easy to flash with Balena Etcher (GUI)
  • Can also be flashed with the dd command
  • The recommended format for best compatibility

• FEL system image:

  • Flashed via FEL mode with the Phoenix tool
  • Mainly used for installing to onboard eMMC
  • Useful for device recovery and mass production
  • Requires some technical experience

Debian Linux

GPT system image (recommended)

A733 SoC image release page

• Radxa Cubie A7S

This page publishes the latest stable and test images. Test versions start with t, stable versions start with r (older stable versions start with b).

• Radxa OS Lite

tip

Radxa OS Lite does not include a graphical desktop environment.

If you need a monitor UI or graphical applications, use the full Radxa OS image.

radxa-a733-bullseye-cli-r6 (Latest): supports booting from microSD and onboard eMMC.

Built-in OpenClaw environment image

radxa_cubie_a733_trixie_cli_beta_v2 image supports booting from microSD and onboard eMMC, with OpenClaw pre-installed. Users only need to configure OpenClaw to get started.

Tina 5.0 AIoT documentation

tip

The Tina5.0 AIoT documentation is primarily available in Chinese.

This documentation is the companion technical support system for Allwinner A-series (A527, A733, etc.) and T-series (T527, etc.) chips, covering the full lifecycle from “hardware design → software development → tooling adaptation → mass production”. The main audience includes:

1. Hardware engineers: design and bring-up support

2. Linux/AIoT developers: drivers and application development based on Tina5.0 SDK

3. Manufacturing engineers: practical troubleshooting during production

4. Compliance/procurement: BOM compatibility and certification information

Hardware documents

• Hardware BOM list

Defines the compatible core components and selection guidance, including camera modules, LCD/eDP panels, Wi‑Fi/BT modules, input sensors, DRAM, and eMMC/NAND storage.

• Hardware design resources

Provides reusable templates and design guidelines such as reference schematics, dev board/prototype schematics, PCB reference templates, design guides, and hardware checklists, plus IBIS models and PMIC selection notes.

• Chip manuals

Includes datasheets, pinouts, user manuals, product briefs, and (for some chips) related PMIC manuals.

Software documents

• SDK module development guide

Focused on driver development for hardware interfaces, with 20+ core modules (display, audio/video, storage & connectivity, performance modules, and system basics) to speed up bring-up.

• Base component development guide

Covers system deployment, multimedia/graphics, testing/tools, security, and heterogeneous computing to reduce the barrier for application and system configuration.

Tooling documents

Practical guides and tooling ecosystem information aimed at improving development efficiency and easing production.

Mass production documents

End-to-end troubleshooting guidance for common production issues.

• Pre-production validation guide: BOM validation process and pilot-run stability checklist to mitigate compatibility and stability risks early.

• Production troubleshooting guide: steps for isolating issues in flashing/boot, MMC/eMMC storage, I/O, display, security, etc., plus examples and solutions.

• Production process specification: Allwinner T-series production guidance, ESD handling, failure analysis processes, and standard operating/compliance requirements to improve consistency and yield.
