The A13 processor from Allwinner runs at 1GHz with a Mali400 GPU. It was designed for integration into tablets. Olimex has made several development board designs based around this chip. This wiki page contains information about hardware and software to help make use of these development boards.

The A13 based boards currently available are

  • A13-OLinuXino-WIFI - Recommended if your developing software for the A13 for the first time as its the only one with network connectivity.
  • A13-OLinuXino - This is the same as the WIFI version but without WIFI module and NAND flash. Note: Android requires NAND flash to run, so this board can't run Android.
  • A13-OLinuXino-MICRO - Similar to the A13-OlinuXino but with less extras


Projects people from the olinuxino community are working on or have finished and how they did it.

Build Bootable SD Card with Debian Run Debian and u-boot, Step by step instructions how to make SD card image.

There is very limited information about the A13 processor. The only detailed data found is an A10 datasheet which has some errors in it apparently. As this is the best source of low level information it is linked here

A10 datasheet

A serial connection can be made to the A13 board, which can help with debugging and is a booting option

Serial connection to A13 Description of how to connect a computer to the A13 board over serial.


The A13-OLinuXino can be partially powered over Micro USB, but to power all peripherals, a 6+ watt DC power supply between 6 and 16 volts can be used. The connector is a positive-center 2.5mm barrel plug. There is also an on-board connector for a Li-PO battery.


A generic wiki for the allwinner devices is here. It contains some great detailed info

Bare Metal programming - no OS

It is possible to program and debug code written directly on the chip without an OS such as linux or android.
The advantage is no kernel overhead and tighter control of the CPU operation.

Using an operating system - Nand flash

The Wifi version of the A13 board comes preprogrammed with android, which is held in the Nand flash.

The image in the Nand flash can be updated using the tools found at the following links:

LiveSuit for Windows

LiveSuit for loading images

to the NAND flash; to activate A13 bootloader do as follows: run Livesuit, disconnect the power supply and USB cable, then press HOME button, apply power supply, attach USB cable and release the button, Livesuit will detect the bootloader and will ask which file to program to the NAND flash.

Prebuilt images that can be programmed into the Nand flash can be found here.

Using an operating system - SD card

The A13 board can boot from an SD card. Just plug it in an imaged uSD card and connect power.

Note: The SD card can easily be corrupted if power is removed while the system is booting or writing to system files. To avoid this do not remove power while it is booting and shut the system down properly before disconnecting power.

Prebuilt images

Some prebuilt images have been created, follow the link below for details.

Prebuilt SD card images running debian

Build your own kernel and image onto SD card

Some developers want more control over the kernel and modules that are included. The link below shows directions to build your own kernel and image it onto an SD card.

Build Bootable SD Card with Debian Step by step instructions how to make SD card image with above Kernel and U-boot

Setup and configure the installed debian image

There are several settings that can be made for a particular hardware configuration in the script file.

The following link explains the script file as well as wifi or ethernet setup and GPIO settings

Configuration of hardware in the debian image

Installing UsbVideoClass(UVC) on A13-OLinuXino board

To work with USB Video Cameras you have to enable the UVC support in the kernel. The link below explains how to do it.

UVC support

Setup VLC player for video streaming on A13-OLinuXino board

To setup video streaming you should first have installed UVC support so you can connect USB cameras to A13-OLinuXino.

A13-SDK Android 4.0.3 ICS

A13-SDK contain everything you need to build Android ACS 4.0.3 NAND image for A13-OLinuXino-WIFI. Both mirrors contain same image a13.tar.gz which you should unpack and follow the instructions inside. Builds on Debian 64bit as on Ubuntu have some problems with Java which we never managed to solve.

A13-SDK Android 4.1 JB

This is version 1.5 of A13-SDK which builds Android 4.1 Jelly Beans image. It works slower than 4.0.3 and we personally do not see any advantage to use 4.1 vs 4.0.3
