Preliminary Ubuntu Image for Tronsmart Draco AW80 Octa-core mini PC

Tronsmart Draco AW80 is an Allwinner A80 based mini PC pre-loaded with Android 4.4. A preliminary Ubuntu image is now available for the device. It’s still a little buggy, but you can access LXDE desktop on an HDMI TV, Ethernet is working, and web browsing is apparently working nicely. Known bugs include FAT32 partitions are read-only, wireless mouse and keyboard are not working (USB versions are OK), shutdown does not work, the user interface is not as snappy as in Android, and YouTube video playback is choppy. The last two issues could be related to the lack of VPU and GPU drivers providing video hardware decoding, and 2D/3D hardware acceleration respectively. The good news is that the company working on Draco AW80 got the GPU drivers from Imagination, and an updated image could be available with hardware acceleration. I’m not sure sure about VPU support, which is extremely important if […]

Rikomagic MK80, MK12, MK05, V5 Android TV Boxes and Sticks Are Now Available for Purchase

Rikomagic unveiled their MK80, MK12 and MK05 Android media players a few week ago, and somehow I missed (or ignored) their Rikomagic V5 TV stick, which looks very similar to Jesurun T034 / MK802 V powered with Rockchip RK3288 processor, and features an Ethernet port, but differs as full-sized USB ports are used instead of mix of micro and full-sized USB ports. All four devices, even five with MK80 Plus, are now available on Rikomagic’s Aliexpress store. MK80 and MK80 Plus are Android mini PCs powered by Allwinner A80 SoC, and are probably using the same Sunchip board as Tronsmart Draco AW80 Meta and Telos, The standard version comes with 2GB RAM, 16GB eMMC, and the “Plus” version with 4GB RAM, and 32GB eMMC, and can be purchased respectively for $155.90 and $199.99 including shipping. MK12 is based on the new Amlogic S812 processor which adds HEVC/H.265 hardware video decoding […]

AllWinner A80 Octa Core big.LITTLE Processor CPU Usage Under Various Loads in Android 4.4 (Video)

Allwinner A80 is one of the few octa core processors featuring ARM’s big.LITTLE technology currently available on the market. The processor comes with four ARM Cortex A15 (big) cores, and four ARM Cortex A7 (LITTLE) core, and tasks will be scheduled to different processor depending on the load to optimize power consumption on mobile devices. However, earlier big.LITTLE processors like Samsung Exynos 5410 has some serious limitations, as they only supported “cluster migration” meaning you could only use the Cortex A7 cluster or Cortex A15 cluster at any given time, so Exynos 5410 could only make use of four cores at most due to hardware limitations. They also used to be two software implementations: In-kernel Switching (IKS) and Global Task Scheduling (GTS). The former could only handle one type of core at the same, and the latter, which I believe is now used in all new devices, can handle any […]

CubieTruck Metal Case Unboxing and Disassembly

CubieTruck Metal Case is a kit comprised of CubieTruck (aka CubieBoard 3), a 128GB SSD, a 5,300 mAh battery, a power adapter, and various cables. In case you are not familiar with CubieTruck, it’s a development board by CubieTech, based on Allwinner A20 dual core ARM Cortex A7 processor with 2GB RAM, 8GB NAND flash, a SATA connector, HDMI & VGA outputs, Gigabit Ethernet, 2 USB host ports, and a mini USB OTG port. CubieTech decided to sent me a kit, as it was featured on CNX Software, and today, I’ll show what’s exactly is inside the kit since the product description is not 100% clear. I’ve been told it’s pre-installed with Lubuntu, so in a separate post next week, I’ll try Linux, report on the SSD performance, and check the battery UPS function, and possibly life on a charge. CubieTruck Metal Case Unboxing I’ve received the kit in a […]

Android 5.0 Lollipop Coming to Allwinner A33 & A80, Rockchip RK3288, and More…

I can often see questions requesting whether SoC XYZ will support Android 5.0 Lollipop. The good news is that last week, I’ve read lots of news about Android 5.0 support on various devices including Nvidia Shield tablet, Motorola G & X smartphones, and of course the Google Nexus devices. A developer (Nanik T.) also ported Android Lollipop to ODROID U3 development board based on Exynos 4412, and he mentioned that “porting was pretty straight forward as KK and 5.0 does not have a lot of differences in terms of HAL”, which means there’s hope for more recent devices and SoCs getting the update. Chinese SoC vendors are also getting the word out that they are working on Android 5.0. Rockchip announced Lollipop support for RK3288 processor (original news in Chinese) probably coming to tablets first, and Android TV boxes later. They used their reference platforms in the provided pictures, 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.
