AllWinner Announces A83T Octa Core Processor for Tablets

So Allwinner has just announced a new processor. I’ve been disappointed recently when I discovered AllWinner A80 only supports Linux 3.4, whereas most competitors are running Android 3.10 stable kernel, and their partner is distributing A80 OptimusBoard development boards, which looks to be a nice hardware platform, but without any Android or Linux SDK… And with their latest press release you have to wonder… They announced AllWinner A83T processor with “eight highly energy-efficient Cortex-A7 cores that could run simultaneously at around 2.0GHz, and implements the advanced big.LITTLE architecture to maximize the battery life”. The only problem is that with big.LITTLE you need big and LITTLE core, and if AllWinner A83T is just having eight Cortex A7 cores, there’s no big to be found… I guess that just means they can turn cores on and off independently… Allwinner must also have adopted Qualcomm or Mediatek press release “strategy”, as they release […]

A80 OptimusBoard Development Board Pictures and Benchmarks

A80 OptimusBoard is a development board featuring the latest AllWinner A80 SoC with 8 ARM Cortex A15/A7 cores in big.LITTLE configuration, and a PowerVR GC6230 GPU. Availability was announced about 2 weeks ago for $345, but partially thanks to reader comments on CNX Software, Merrii Technology decided to lower the price to $169 (and $50+ for shipping) to stay competitive against similar boards such as Hardkernel ODROID-XU3. I’ve now received a sample for evaluation. I won’t go again through the specs, but today I’ll take a few pictures of the board, and provide benchmark results to compare them to the ones I got with Rockchip RK3288. Normally, I would also play with the SDK provided with the board, but sadly (and amazingly), there’s currently no such SDK for A80 OptimusBoard, except a leaked Linux SDK which failed to build with recent tools and operating systems. A80 OptimusBoard Pictures I’ve received […]

AllWinner A80 Linux SDK Released

After Android 4.4 SDK for AllWinner A31 last week, another AllWinner software development kit has been seen in the wild, this time for the new AllWinner A80 octa-core processor. A80 SDK includes source code for the Linux Kernel and U-boot, as well as buildroot, and various AllWinner tools. I’ve also noticed AllWinner A80 datasheet is available, but with the strict minimum information (45 pages). Let’s get the code, and extract it:

Now we need to configure the build:

sun9i is the codename for AllWinner A80, not sure what w1p1 means. Dragonboard must be the internal Allwinner development board, but I just selected Linux, since the SDK does not come with Android, and finally I opted for optimus, which could stand for OptimusBoard. You may need to install extra dependencies in your build machine, for example (in Ubuntu 14.04):

Now let’s start buildroot which should retrieve the toolchain, […]

Interview with Allwinner Regarding their Linaro Membership

Since Allwinner has joined the Linaro Digital Home Group earlier this year, many people, including myself, have wondered what it means in terms of Linux support, and the engagement with the open source community. Following up on an idea from a regular reader, I’ve decided to asked a few questions to Ben-El Baz, marketing manager at Allwinner, and Linaro contact for Allwinner, which he kindly answered, and accepted to be published on CNX Software. CNXSoft: Why did Allwinner decide to join Linaro, and especially the Digital Home Group? Allwinner: One of our company’s goals is to be a technology leader.  It’s ambitious but not too far-fetched given the background of our leadership and engineering team.  There’s an extremely talented group of guys behind the scenes here! Leading is difficult unless you’re involved in collaborative organizations like Linaro that work on new technology.  Joining Linaro is an opportunity for us to […]

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. Download 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: Android 4.4 firmware LCD output (password: w1s6) Android 4.2 firmware LCD output (password: b7de) Android 4.2 firmware VGA output (password: nfqw) Linux firmware (password: ibal) It takes a very long time to download the SDKs, so I haven’t checked the files, and […]
