Can Rockchip RK3288 Android TV Boxes Play Videos at True 4K UHD / 2160p Resolution?

[Update 2: Now that I have a 4K TV, I’ve redone the test myself, and Rockchip RK3288 can play 4K videos properly. The mistake was to use Software decode in MX Player which renders to the framebuffer instead of the video buffer. Visit the post entitled 4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards for details.] [Update 1: The post has now been updated, after it was clear one of MX Player options was misunderstood. The conclusion remains the same] Over the last few years there have been complains about Android TV boxes decoding 1080p video, rendering them to a 720p frame buffer, and upscaling them back to 1080p resolution for video output, so you ended up playing 1080p videos at a real 720p resolution. I never investigated the issue in details, and thanks to new media players now coming with a 1080p […]

KDDI Unveils Tiny BLE/Zigbee Development Board Running Mozilla Firefox OS

KDDI has recently announced Open Web Board, an HDMI TV stick powered by Rockchip RK3066, and running Firefox OS, just like the recently announced MatchStick. The board is however aimed at embedded and web developers who want to create apps for Firefox OS, and interface with external devices over Bluetooth Low Energy or Zigbee (optional module) communication, optionally using Gluin, a web based graphical “application development tool that enables simple linking programming between electronic devices”. Open Web Board specifications: SoC – Rockchip RK3066 dual core Cortex A9 processor @ 1.6 Ghz with Mali-400 MP4 GPU System Memory – 1 GB RAM Storage – 8 GB flash Video Output – HDMI USB – 1x USB 2.0 host port, 1x micro USB for power Connectivity – 802.11 b/g/n Wi-Fi (AP6210 module), Bluetooth 2.1 (HFP/A2DP/AVRCP)/4.0 GATT. and optional Zigbee via external module Dimensions – Small This dongle runs Firefox OS 1.4. KDDI showcased […]

Unboxing of MXQ S85 Android Media Player Powered by Amlogic S805 Processor

Gearbest sent me MXQ S85 Android media player powered by Amlogic S805 quad core processor with 1GB RAM, 8GB internal storage, and Ethernet/Wi-Fi/Bluetooth connectivity. MXQ S85 looks very similar to EM6Q-MXQ, another Amlogic S805 based Android STB, which I reviewed last week, but these are two distinct hardware platforms. Today, I’ll take some pictures of the devices, and the board to see which components are used, and who made the board, and I’ll write a full review in a few days. MXQ S85 Pictures I’ve received the parcel via DHL in the nameless package below where they just indicate it’s and Android TV box with a quad core processor, quad core GPU, pre-loaded with XBMC, and supporting HEVC / H.265 The package contains the box, HDMI and AV cables, an OTG adapter, a 5V/2A power supply, an IR remote requiring two AAA batteries, and a user’s manual in English. The […]

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 […]

Review of Tronsmart Orion R28 Meta 4K/H.265 Android TV Box

It’s been a little while since I unboxed Tronsmart Orion R28 Meta Android TV box, but since the product was still consider “beta” by GeekBuying, I wanted to wait for a OTA firmware update (109k4), which was released at the beginning of the week. Since I’ve already listed the technical specifications, and showed pictures of the board and device, I’ll focus on feature tests and benchmarks results in the review. First Boot, Settings and First Impressions I quickly tried the basic infrared remote control, inserting two AAA batteries, and it does the job, but for Android, you really need a pointing device, so I switched to Mele F10 Deluxe air mouse during testing. I’ve connected a whole bunch of cable, and peripherals to the box including an HDMI cable, a USB hard drive, an Ethernet cable, a USB webcam, and a USB hub with RF dongles for my air mouse […]

Tronsmart T2000 EZCast Pro Dongle Supports MHL, Split Screen, Improves Wi-Fi Performance

EZCast dongles, tiny HDMI streaming Wi-Fi stick with support for Airplay, Miracast, DLNA, and their own proprietary EZCast protocol first appeared about a year ago. I’ve reviewed a few including Tronsmart T1000 and MeLeCast S1, and found them to work relatively well, with some caveats, in Android. There’s now a new EZCast Pro wireless adapters that adds features such for four split screens display, conference control via web browser, and content broadcast to multiple screens, as well as improved wireless performance thanks to 2T2R Wi-Fi. Tronsmart T2000 is the first device I’ve heard of, that’s EZCast Pro capable. Tronsmart T2000 hardware specifications: SoC – Action Semi AM8251 @ 500MHz (MIPS) System memory – 256 MB DDR3 RAM Storage – 128 MB NAND Flash Video output – HDMI 1.2 / MHL 2.0 Wi-Fi – Single band 802.11 a/b/g/n Wi-Fi 2T2R up to 300 Mbps Standards – Miracast, Airplay, DLNA, and EZCast […]
