This document lists all the ARM Allwinner SoCs that are currentlysupported in mainline by the Linux kernel. This document will alsoprovide links to documentation and/or datasheet for these SoCs.

Allwinner Technology is a fabless semiconductor company that designs mixed-signal systems on a chip (SoC). The company is headquartered in Zhuhai, Guangdong, China.It has a sales and technical support office in Shenzhen, Guangdong, and logistics operations in Hong Kong. Since its founding in 2007, Allwinner has released over fifteen SoC processors for use in Android-based tablets, as well as. Eva Wu from Allwinner marketing sent me the new logo for A80. There is no much info about it yet, but it will be 8 core (4xCortex-A15 and 4xCortexA7) and Allwinner is working now on it. Probably it will have 8-16 GPU co-processors too, we hope these to be MALI but there are great chances these to be PowerVR like A31, Eva is silent on this. Previously in this series, we investigated building and running a minimal linux server on the Allwinner A80 Optimusboard. While that was a great exercise in learning about the A80 and its SDK, the output of that work was not all that useful. Additionally, we were still missing major hardware components such as ethernet, wi-fi, and NAND. Allwinner A80 SoC. The A80 contains 1 main clock control unit, and some subsystem specific clock control units at separate addresses. These include the USB, display engine, and MMC. The MMC clocks can be supported by the old clock drivers, hence here we do not add a new driver for it.

Use sun8i-a83t-allwinner-h8homlet-v2.dtb device-tree tree binary. There is a 3.4 source tree for the A83T at Module Description CPU: Cortex-A7 MP4 in 2 clusters, the MCPM is more likely as the A80 CCI400: It's same as the A80 DRAMM: It's more likely as the A80 Timer: It's same as the A31 and A20 CCU: It's more likely.

Cubieboard is a single-board computer, made in Zhuhai, Guangdong, China. The first short run of prototype boards were sold internationally in September 2012, and the production version started to be sold in October 2012.^[1] It can run Android 4 ICS, Ubuntu 12.04 desktop,^[2]Fedora 19 ARM Remix^[3] desktop, Armbian, Arch Linux ARM,^[4] a Debian-based Cubian distribution,^[5]FreeBSD,^[6] or OpenBSD.^[7]

It uses the AllWinner A10SoC, popular on cheap tablets, phones and media PCs. This SoC is used by developers of the lima driver, an open-source driver for the ARM Mali GPU.^[8] At the 2013 FOSDEM demo it ran ioquake 3 at 47 fps in 1024×600.^[9]

The Cubieboard team managed to run an Apache Hadoopcomputer cluster using the Lubuntu Linux distribution.^[10]

Technical specifications[edit]

Cubieboard1[edit]

The little motherboard utilizes the AllWinner A10 capabilities^[11]

SoC: AllWinner A10
- CPU: Cortex-A8 @ 1 GHz CPU,
- GPU Mali-400 MP
- video acceleration: CedarX able to decode 2160p video
- display controller: unknown, supports HDMI 1080p
512 MiB (beta) or 1GiB (final) DDR3
4 GB NAND flash built-in, 1x microSD slot, 1x SATA port.
10/100 Ethernet connector
2x USB Host, 1x USB OTG, 1x CIR.
96 extend pin including I²C, SPI, LVDS
Dimensions: 10 cm × 6 cm

Cubieboard2[edit]

The second version, sold since June 2013, enhances the board mainly by replacing the Allwinner A10 SoC with an Allwinner A20 which contains 2 ARM Cortex-A7 MPCore CPUs and a dual fragment shader Mali-400 GPU (Mali-400MP2).^[12]

This board is used by Fedora to test and develop the Allwinner SoC port of the distribution.^[13]

There is also a version available with two microSD card slots.^[14]
