Earlier this month, a new firmware for Tronsmart Prometheus with Android 4.2 and XBMC with hardware acceleration has been released. Several users left divergent opinions about this firmware, so I’ve decided to give it a try, and write an updated review of Tronsmart Prometheus. I’ll focus on the new features and performance of Android 4.2, XBMC video testing, and see if some of the bugs I found in my earlier review have been fixed. Android 4.2 Features and Benchmarks The firmware file and instructions are available on Tronsmart website. The procedure is straight forward so I won’t repeat it here. During the first boot after the upgrade, you’ll be taken through a wizard to configure your device (e.g. Ethernet, WiFi,…). The first think you’ll notice is a slightly different Home Screen in Android 4.2. There are several small UI improvements / modifications, but the most interesting features for me in […]
Linaro 13.03 Release with Linux Kernel 3.9 and Android 4.2.2
Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2. This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available. Here are the highlights of this release: Automation and Validation A simple CLI tool for communicating with […]
Droid Stick A2 mini PC Recovery with AMLogic’s Hardware Flash Tool
In some circumstances, for example by installing the wrong firmware or doing something wrong by playing god (as a root user), it’s possible to brick your device. This happened to me with one of my Droid Stick A2 mini PCs based on AMLogic AML8726-MX. I changed some files in /system/etc/permissions directory, lost Wi-Fi access, and even replacing my changes with the backup files would not solve the problem. It also changed some permissions in the system, and it was not possible to restore the firmware the usual way. At the end of last month, dbtablets left a comment with download links to “Amlogic USB Burning tool”, but I only decided to give it a try today, and after some efforts I was successful. Just make sure you only use this method as last resort, i.e. a standard firmware upgrade does not work, and you’re about to throw your device in […]
UG008 and UG008B Rockchip RK3066 Android 4.1 Set-Top Boxes
For those of you who prefer to have a full sized set-top box with an Ethernet port powered by Rockchip RK3066, there aren’t that many options (i.e. Mini X5, TVi7, Wise TiVi Box) and they are usually significantly more expensive than equivalent mini PCs. But there’s no a cheaper option with UG008, a media player powered by Rockchip RK3066 with 1GB RAM, 4 to 8 GB Flash, as well as Ethernet and Wi-Fi support, that sells for around $62 and up. Here are the specifications of this media player: SoC – RK3066 Dual Core Cortex A9 @ 1.6 GHz + Mali-400 MP4 GPU System Memory – 1GB DDR3 Storage – 4 to 8 GB NAND Flash + micro SD slot (up to 32GB) Connectivity Wifi – 802.11b/g/n with external antenna 10/100M Ethernet Video Output – HDMI + AV Video Formats and Codecs – WMV, ASF, MP4, 3GP, 3G2, M4V, AVI, […]
Mini PCs (MK802+, UG802, GK802 & iStick A200) Linux Performance Comparison
Ian MORRISON (linuxium) has tested Linux with several mini PCs powered by different processors. The main point of his tests was to evaluate the performance difference between running Ubuntu 12.04 natively, or in a chroot in Android using tools such as Complete Linux Installer. I previously tried Linux on Android in ODROID-X, and found the applications start time when running from an low-end SD card pretty dismal, and the graphics performance poor. Ian had a different approach, and decided to use a subset of Phoronix Suite benchmarks to compare different hardware / software combination and posted the results in “mini PCs” G+ community. There’s a lot of data, and analyzing the results is not really straightforward without spending some time looking at the data. In this post, I’ll explain how the tests have been conducted, explain the results and try to draw a conclusion. Mini PCs and other Hardware Under […]
Renesas R-Car H2 is an Octo Core big.LITTLE Processor for Your Car
Renesas announced a new automotive SoC called the R-Car H2 that features 4 Cortex-A15 cores together with 4 Cortex A7 cores (optional) in big.LITTLE configuration, as well as an Imagination PowerVR Series6 G6400 GPU. This SoC can optionally come with Renesas SH-4A, a real-time processing CPU core acting as a multimedia engine (MME) , and Renesas’ IMP-X4 core, a real-time image processing unit that enables developers to implement augmented reality application such as 360-degree camera views and image recognition. This Renesas processor is a multimedia power house, as it can handle 4x 1080p video en/decoding, including Blu-Ray support at 60 frames per second, as well as image/voice recognition and high-resolution 3D graphics with virtually no CPU usage. Here are R-Car H2’s specifications provided on Renesas website: Product number R8A7790x Power supply voltage 3.3/1.8 V (IO), 1.5/1.35 V (DDR3), 1.0 V (Core) CPU core ARM Cortex-A15 Quad ARM Cortex-A7 Quad (device […]
OpenELEC 3.0.0 on Raspberry Pi – Installation and Video Tests
Yesterday, OpenELEC developers announced the release of OpenELEC 3.0.0, a lightweight OS running XBMC Frodo 12.1 for several platforms including the Raspberry Pi (OpenELEC stands for Open Embedded Linux Entertainment Center). When the Raspberry Pi was initially released, I did not feel like testing it as a media center, mainly because of codecs limitations. But over time, this has improved with the availability of MPEG-2 and VC-1 codecs (for a fee), and GPU accelerated support for free codecs such as VP6 and VP8, so today I’ve tested to give a try and install OpenELEC 3.0.0 on my Raspberry Pi. I’ll first give installation instructions, then test several types of videos container formats, and video / audio codecs, as well as give some quick impression about the performance and stability of OpenELEC on this low cost board. Installing OpenELEC on Raspberry Pi To install OpenELEC, I basically followed the instructions provided […]
Zealz GK802 Is (Temporary?) Available for $69.99 on GeekBuying
Zealz GK802 is a mini PC based on Freescale i.MX6 Quad processor, with 1GB RAM, 8 to 16 GB internal memory (internal micro SD card). The main selling points of this HDMI dongle is that it’s the only currently available quad core processor (about to change), it’s hackable and unbrickable with easy access to the serial console, full support for Linux with hardware video decoding and 2D/3D acceleration (work in progress), and Freescale has released proper software and hardware development resources for the i.MX6 processor. As mentioned in my review of Hi802 mini PC, the downside is that Vivante GC2000 GPU performance is lower than the Mali-400 MP4 found in Rockchip RK3066 mini PC, and its price (usually above $90) is about double the price of Rockchip RK3066 mini PCs. We can’t do anything for Vivante GC2000 performance, but Roman found a coupon code “FVKIWVAG” on a Russian forum that […]
