AllWinner A31 Android & Linux SDKs, and Documentation Leaked

AllWinner A31 software development kits (SDK) for Android 4.2 / 4.4 and Linux can now be downloaded, and relevant documentation has also been made available, including HummingBird A31 system brief and system manual. Part of the documentation is in English, but lots of it, is in Chinese only.

AllWinner_A31_SDK_Android_LinuxDownload links to AllWinner A31 SDKs for HummingBird A31 development board, but they may be useful for other hardware platforms based on AllWinner A31:

  • Android 4.4 SDK (password: 5ck9) – a31_v4.5_hummingbird_kfb_ok.tar.gz (6.04 GB)
  • Android 4.2 SDK (password: tz17) – a31_hummbingbird_V3.3_v2_kfb_0k.tar.gz (3.99 GB)
  • Linux SDK (password: kdcw) – A31_MerriiLinux_V3.3_v1.tar.gz (1.17 GB)

There are also links to firmware files specific to HummingBird:

It takes a very long time to download the SDKs, so I haven’t checked the files, and hopefully there’s also some documentation inside. But if you want a quicker look at the documentation including AlLWinner A31 datasheet, AllWinner A31 tablet and STB schematics, and more, you may want to have a look at http://wens.csie.org/a31/, but soon these may become available on linux-sunxi.org.. [Update: The SDK can now downloaded @ http://dl.linux-sunxi.org/SDK/A31/ and the documentation @ http://dl.linux-sunxi.org/A31/]

On a related note, there will be soon another AllWinner A31 development board and systems-on-module (A31-SOM-EVB + A31-SOM) made by Olimex.

Thanks to Domingos!

This is 1999, 40KB/sec, 20 hours to download 4GB…

Wonder why they are not just using GitHub?

“Allwinner does not actively participate in or support this community. In fact, it is violating the GPLv2 license in several ways and has so far not shown willingness to resolve this.”

Looks like this is still an issue http://linux-sunxi.org/Main_Page

So wondering is the source code is complete for A31? It is still not for previous SoC models

Try baidu application for faster download.

@cnxsoft
Merrii released these SDKs and firmware to people who’ve bought the Hummingbird and registered in their forum.
However, I’ve asked them and they’ve agreed for me to upload them publicly, which I will do very soon (SDK only).

@zooba
Slow is relative to where you are. They are hosted in China, which doesn’t have the best international connections. 🙁

@Harley
The SDK should be complete enough for a full system. I haven’t tested it though. It does contain blobs for certain things, such as NAND, GPU, and VPU.

I said Merrii gives you all needed files and manuals after buy (they said that), I did not buy finally as I’m not total sure if a change Rockchip-Allwinner is a good idea.

Yes, as Gabe said, the application from baidu is the recommended to download big files

Make a random gmail account and get 10GB free. Put the file on Google’s servers using GDrive. Set the GDrive file for public access and pass the URL out. GDrive is about 10,000x faster than Baidu file access.

But those files are in baidu because they are chinese companies. Here in China baidu is the faster service probably. Also most of these services are blocked. I use mega for my uploads, but from here I prefer download files from baidu with the chinese IP.

Anyway chinese companies must think about using mega or similar even its very slow to upload the files there from china…

The 3 A31 SDK versions have been made available at http://dl.linux-sunxi.org/SDK/A31/
This should be faster for some folks, as the site is in Europe.

Also the A31 documents have been moved to http://dl.linux-sunxi.org/A31/
Would it be possible to replace the URL in the article with this one?
I intended to host the files until I moved them over to linux-sunxi.

I am more interested in embedded hardware not in app development. There is plenty books on how to write apps but very few on the hardware part, for example on how to create a ROM to a specific SoC.

Apart from Linux, I was thinking in study a few books I found on embedded systems:embedded Android and embedded Linux.
What do you think? Do i need to study anything else/
Thanks in advance.
