Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this […]

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 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 […]
