AllWinner A80 based Cubieboard4 Development Board is Now Available for $100 (in China)

Allwinner and Cubietech announced they were working on Cubieboard8 in May, before we got to see some pictures of the first engineering samples. Cubieboard8 has now been renamed to Cubieboard4, also known as CC-A80 (CubieTech single board Computer A80), and the company has listed the board on Taobao for 620 RMB (~$102), with shipping scheduled for October 30. Cubietech CC-A80 board specifications, which have changed since the first pictures were released in July: SoC – AllWinner A80 octa core 4x Cortex A15 @ 2.0GHz, 4x Cortex A7 @ 1.3GHz, and Imagination PowerVR G6200 GPU System Memory – 2GB DDR3 Storage – 8GB eMMC (25MB/s read and write speed), micro SD Card slot Video Output – HDMI 1.4, and VGA Audio I/O – HDMI, 2x 3.5mm audio jacks for audio output and microphone Connectivity – Gigabit Ethernet, dual band Wi-Fi 802.11 b/g/n up to 300 Mbps + Bluetooth 4.0 (AP6330 module) […]

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 […]

ITEAD Core AW204X AllWinner A20 SoM and Core EVB Baseboard

ITEAD Studio has been making systems-on-module based on Allwinner processors for a little while which are found in the company’s IBOX mini PC, MOD Duo guitar pedal, and more. They’ve now launched a new system-on-module with a 204-pin SO-DIMM connector instead of the headers used in the earlier modules. ITEAD Core AW2041 / AW2042 SoM specifications: SoC- AllWinner A20 dual core ARM Cortex-A7 @ 1 GHz + ARM Mali 400 MP2 System Memory – 1 or 2 GB DDR3 RAM (AW2014: 1GB, AW2042: 2GB). Storage – 4GB NAND Flash, micro SD card slot (on the back), SATA connector. Connector – 204-pin SO-DIMM edge connector with UART, I2C, SPI, LCD, I2S, LVDS, GPIO, etc.. signals Misc – Built-in RTC, reset, FEL and power buttons. Power – 5V supply, 3.3V I/Os. AXP209 PMIC. Dimensions – 67.60 x 48.25 x 1.6 mm Weight – 35 grams Temperature Range – Commercial To facilitate development, the […]

Allwinner A80 Android TV Boxes Coming Soon, Starting with Zero Devices Z8C Alice

Allwinner A80 based tablets such as Onda V989, and development boards such as A80 OptimusBoard started to ship one to two months ago, but there was absolutly no news about Android mini PCs / media player based on the latest Allwinner processor. This is about to change as ZeroDevices twitted about their Z8C Alice TV Box, apparently designed by Sunchip, and in collaboration with a UK based digital signage company called Eclipse Digital Media. Preliminary technical specifications that we can infer from the picture above: SoC – AllWinner Ultra Core A80 4x Cortex 15, 4x Cortex A7 big.LITTLE processor with Imagination Technologies PowerVR GC6230 GPU with support for OpenGL ES 1.1/2.0/3.0, Directx 9.3 System Memory – N/A Storage – ?? GB eMMC + SD card slot + SATA port (most probably via a USB 2.0/3.0 bridge) Video Output – HDMI + AV port Audio – HDMI, AV, and optical S/PDIF […]

Linux 3.17 Released

Linus Torvalds announced the release of Linux Kernel 3.17 on Sunday: So the past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule (as opposed to the optimistic “maybe I can release it one week early” schedule that was not to be). However, I now have travel coming up – something I hoped to avoid when I was hoping for releasing early. Which means that while 3.17 is out, I’m not going to be merging stuff very actively next week, and the week after that is LinuxCon EU… What that means is that depending on how you want to see it, the 3.18 merge window will either be three weeks, or alternatively just have a rather slow start. I don’t mind getting pull requests starting now (in fact, I have a couple already pending in my inbox), but I likely won’t start processing […]

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 […]

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:

sudo apt-get install dkms git build-essential
git clone https://github.com/linux-sunxi/sunxi-livesuite.git
cd sunxi-livesuite/awusb
make
sudo cp awusb.ko /lib/modules/`uname -r`/kernel/
sudo depmod -a
sudo modprobe awusb
cd..

sudo apt-get install dkms git build-essential

git clone https://github.com/linux-sunxi/sunxi-livesuite.git

cd sunxi-livesuite/awusb

make

sudo cp awusb.ko /lib/modules/`uname -r`/kernel/

sudo depmod -a

sudo modprobe awusb

cd..

In order to use LiveSuit as a normal user, you also have […]

Linux based MOD Duo Multi-Effects Pedal is Powered by an AllWinner A20 SoM (Crowdfunding)

If you are both a maker and a musician, MOD Duo multipurpose pedal may be a fun “toy” to play with. It’s an embedded computer comprised of a Hi-Fi soundcard (baseboard) powered by the same ITEAD Studio A20-CORE system on module found in ITEAD Studio IBOX, fitted into an enclosure with a pedalboard interface, and two graphics displays. You can create and share your own effects, or download the one made by the community using LV2 sound plugins, an open sound processing standard. A MOD Arduino Shield is also available to create new peripherals. Some technical specifications of the MOD Duo: SoC – AllWinner A20 dual core Cortex A7 processor @ 1GHz (AllWinner A23 is part of stretch goals) Two audio inputs Two audio outputs Stereo headphones output MIDI IN and MIDI OUT Cirrus Audio Codec USB – 1x USB Host for bluetooth, Wifi adapters and MIDI peripherals, 1x USB […]
