Linux Benchmarks – Rockchip RK3288 vs Exynos 5422 vs AllWinner A80 vs Intel Atom Z3735F

With all these Intel Atom Z3735F been released right now at a price similar to ARM based mini PCs, many people, including myself, are wondering about the performance of the low cost Intel processor against their ARM competitors. Ian Morrison just published some results from Phoronix Test Suite comparing the performance of  Firefly-RK3288 (Rockchip RK3288), ODROID-XU3 Lite (Samsung Exynos 5422 BIN2), and A80 OptimusBoard (Allwinner A80) in Linux (Ununtu 12.04.5), against the performance of MeegoPad T01 (Intel Atom Z3735F) running Linux from a Live CD on a USB drive. Some of the benchmarks failed because Phoronix Test Suite got apparently confused with the file systems located on a USB drive, but at least we’ve got a comparison point, and the results are a bit confusing, as they’re no clear winner. In some tests like FFmpeg, the Intel SoC really crushed the ARM competition being at least twice as fast as Exynos 5422, and about four times faster than RK328 and …

How-to Install Ubuntu on Allwinner A80 Powered pcDuino8 and A80 OptimusBoard

Last month, pcDuino released Android 4.4 and Ubuntu images for pcDuino8 board powered by Allwinner A80 octa core processor, and since it’s the same board layout as A80 OptimusBoard, I decided to try it out, but it failed as the update script would try to flash it to a partition that’s too small for the root file systems. But last week, Ian Morrison and Minidodes gave it another try, and successfully booted Ubuntu, or more exactly Lubuntu, on A80 OptimusBoard. Both their screenshot reports sun9i platform in /proc/cpuinfo, so that’s definitely Allwinner A80, but only one core is shown. I’m not sure if it’s because the other are idled and don’t show, or for some reasons, the kernel only supports one core at this stage. Anyway, here’s how they did to install Lubuntu: Flash the kernel (pcduino8_kernel_livesuit_20141008.img) with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard. Extract the rootfs (pcduino8_ubuntu_20141008.rar) to an SD card or USB …

Updated Android 4.4 Beta and Ubuntu Images for pcDuino8 / A80 OptimusBoard Boards Released

pcDuino8 and A80 OptimusBoard are the only two Allwinner A80 development boards currently “somewhat” available, and albeit the PCB color is different, every else is basically identical, and pcDuino8 firmware should probably run on A80 OptimusBoard and vice versa. If you own any of these boards, you may interested in two images, one with Android 4.4 (beta), and one with Lubuntu, recently released by pcDuino / Linksprite. Android 4.4 (beta) 2014-10-08 – sun9iw1p1_android_optimus.img to be flashed with PhoenixCard (Windows) or Livesuit (Linux) Lubuntu 14.04? 2014-10-08 is comprised of two files: Kernel – pcduino8_kernel_livesuit_20141008.img to be flashed with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard. Rootfs – pcduino8_ubuntu_20141008.rar. First extract the rar files to the root of an SD card or USB flash drive. There should be two files: pcduino8_ubuntu_20141008.img and update.sh. Now connect the mass storage device to pcDuino3 / A80 Optimusboard, and reboot the board to flash the image to /dev/nandd automatically. The serial …

How to Upgrade Allwinner A80 OptimusBoard Firmware

After informing Allwinner I had some rather slow write speed (3MB/s) to the NTFS partition of my USB drive on my A80 OptimusBoard, they kindly provided a new compressed Android firmware image (sun9iw1p1_android_optimus_v1.2_20140930.img.7z) with some NTFS optimizations that can be downloaded from baidu (password: x2tz), mega.co.nz or simos.info (please only use this link, if the other two do not work as it’s a private website and monthly bandwidth may be limited). I vaguely remember tools like LiveSuit (Linux) or PhoenixSuite (Windows), and I ended up on sunxi-linux Livesuit wiki as I’m running Ubuntu 14.04 on my PC, but you should be able to flash the firmware with PhoenixSuite if you run Windows. The instructions below can also be used for other Allwinner based devices. First you need to install LiveSuit, and build Allwinner USB drivers as follows: In order to use LiveSuit as a normal user, you also have to create /etc/udev/rules.d/50-awusb.rules with the line: Finally, we can start the …

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, and build u-boot and the Linux kernel: So it’s looking for Linaro gcc …

RYVAL Elf Could Be the World’s Smallest USB Flash Drive

Hexino, a French company selling “fashion technology” under the brand RYVAL, may be offering the smallest USB flash drives available today with RYVAL Elf. This tiny mass storage device measure 1.8 cm x 1.8 cm x 0.68 cm, weights only 2 grams, and is available with capacities of 8GB, 16GB, or 32GB. The specifications listed on the company’s website are as follows: USB 2.0 compatible with Windows Vista, 7 and 8 Write speed – Up to 4 MB/s Read speed – Up to 12 MB/s Weight – 2 grams Dimensions – 18 mm x 18 mm x 6.8 mm Capacity – 8 GB to 32 GB Colors – Blue, Pink, and Green Material – Aluminium They only mention compatibility with Windows, but I don’t see why it could not work with Mac, Android, and Linux based devices and computers. It’s small enough to replace microSD cards for permanent storage expansion, so if you’ve got an Android tablet or mini PC …
