So This is How Allwinner A80 Cheats at Antutu Benchmark…

Ever since Allwinner A80 was released, the Antutu scores did not add up with some devices getting around 30,000 points, while other devices scoring close to 50,000 or even higher. But what about 143,430 points? Now that would be impressive, and that’s exactly what Byron got in his Tronsmart Draco AW80 box, after changing a single parameter. The screenshot above reports a Nexus 10 because he must be using one of Freatab ROM, where they often change the device name for better Google Play compatibility. Nevertheless what kind of sorcery is that? How could he achieve this? It turns out build.prop, as a key called ro.sys.hiritsu. It’s set to 30 in the stock firmware, but if you change this to 95, some magic happens, and you get the very high score above. Byron reported his box got pretty hot with this setting, so it’s probably better not to try a […]

$60 MarsBoard Rockchip PX2 Development Board Runs Ubuntu, Debian, openSUSE, or Android 4.4

Haoyu Electronics has made a new board similar to their MarsBoard RK3066, but instead of using a CPU module with Rockchip RK3066, they’ve used the industrial version of the chip called Rockchip PX2 dual core Cortex A9 processor. The board is also comprised of a baseboard and CPU module (CM-PX2), and based on the name of the pictures it’s using the exact same PCB: CM-RK3066 SoM, and SOM-RK3066 baseboard, but they simply replaced RK3066 by PX2, and increased the NAND flash capacity to 8GB. CM-PX2 Computer-on-Module: SoC – Rockchip PX2 dual core ARM Cortex A9 @ 1.4 GHz + Mali-400MP4 GPU System Memory – 1GB DDR3 Storage – 8 GB NAND Power Management Unit – TPS659102 Misc – TX indicator LED use for debug, Power Indicator LED 10/100M Ethernet PHY – LAN8720A Connectors – 2x 100- pin for baseboard connection, 40-pin connector (unsoldered) Dimensions – 70 x 58 mm SOM-RK3066 […]

AV Receiver and 4K UHD TV Crowdfunding for Better Reviews on CNX Software

I’ve written a fair amount of reviews, mostly of Android mini PCs and development boards, and I intend to continue, but there are currently a few things I’m unable to test: S/PDIF and HDMI pass-through, and 4K video output, 3D videos, and HDMI-CEC. The main reason is that the AV receiver and TVs required to test this are rather expensive, and these are not something I really need personally, since I seldom watch movies myself, I purchased a new Full HD TV last year, and I don’t expect to access 4K content for a few more years. Yet it would be interesting to prospective buyers to find out if advertized features such as audio pass-though of 5.1 & 7.1 codec does work, and whether 4K output (listed and real), HDMI-CEC, 3D videos and other features not supported by my current Panasonic can work properly. It would also be fun for […]

WeTek Play Set-Top Box Now Also Comes with an ATSC Tuner

WeTek Play is an Android media player that comes with a digital TV tuner, and in my recent updated review with a DVB-S2 tuner I found out that the software for live TV either via Internet or satellite was pretty good, and despite the older Amlogic AML8726-MX processor used in the box, it could still be recommended for watching live TV, with featuring like PVR, TimeShifting and EPG working reasonably well. At launch however, WeTek Play was only available with DVB-S2 or DVB-C/T/T2 tuners, so North American did not have the option to watch free-to-air digital TV on the box. This has now been resolved, as the company has launched Wetek Play with an ATSC tuner. The rest of the specifications for the ATSC model are exactly the same: SoC – Amlogic AML8726-MX dual core Cortex A9 @ 1.5GHz with a dual core Mali-400MP GPU System Memory – 1GB DDR3 […]

Patchsets for Nvidia Tegra K1 “Denver” Submitted to Linux Mainline

Some patchsets have been submitted for Nvidia Tegra 132 a few days ago to the Linux ARM Kernel mailing list. Tegra 132 is the codename for the 64-bit version of Tegra K1, and they’re also a mention of Norrin64 FFD board, that should be a Chromebook reference design.

Tegra114 and Tegra124 are the codename for Tegra K1 32-bit processor with Tegra124 clocked at a higher frequency. Norrin64 board dts does not seem included in the patchsets, but it’s available from Chromium OS code, and shows it’s using 2GB RAM too. That also means Chrombooks like Acer Chromebook 13 (CB5) or HP Chromebook 14 with the 32-bit version of the Tegra K1 might soon get an upgrade to the 64-bit version. Thanks to David for the tip.

PC Partner N258N1-F is a Linux mini PC Powered by Nvidia Tegra K1 Processor

Nvidia has done a great job porting Linux to their Tegra K1, and it’s one of the only ARM processor with a GPU supporting OpenGL, which helps a great deal with Unity for example. Nexus 9 supports Ubuntu (somewhat), and platforms like Jetson TK1 board are suitable to developers, but as I and others wondered why nobody ever made a Tegra K1 mini PC, I’ve been informed that such device existed already with PC Partner’s N258N1-F mini PC. N258N1-F technical specifications: SoC – Nvidia Tegra K1 quad-core ARM Cortex A15r3 processor with Kepler GPU System Memory – 2 GB RAM Storage – 16 GB eMMC + SD card slot Video Output – HDMI up to 3840×2160 @ 30Hz, 4096×2160 @ 24Hz or 3200×2000 @ 60 Hz Audio I/O – HDMI, headphone jack, and microphone jack Connectivity – Gigabit Ethernet and Wi-Fi (with external antenna connector) USB – 2x USB 2.0 […]

Rockchip RK3036 Android 4.4 TV Boxes with H.265 Codec Support To Sell for $10

Rockchip announced RK3368 64-bit processor yesterday for mid-range tablets and 4K media player, but the company also have some new ultra low cost TV box and HDMI TV stick solution with Rockchip RK3036 dual core Cortex A7 processor that will go into $9.9 TV boxes running Android 4.4. The price is most probably factory price, but that means $20 H.265/HEC capable Android media players are probably around the corner. You can already get an RK3066 TV dongle (MK808 and similar) for less than $30 in Aliexpress, so the new solution will likely decrease the price by $5 to $10. Technical specifications of RK3036 reference design: SoC – Rockchip RK3036 dual core Cortex A7 processor @ up to 1.2 GHz with Mali-400MP GPU System Memory – 256MB DDR3 or DDR3L Storage – 2GB flash. RK3036 supports MLC NAND, eMMC 4.5. Video & Audio Output – HDMI 1.4a. The chip also supports […]

Meet the First Nvidia Tegra X1 “Tablet”: Nabi Big Tab XL

Nvidia announced their latest Tegra X1 processor at CES 2015 earlier this week, and after showcasing it’s computing and power-saving capabilities, the company focus on its applications: automotive dashboard and driverless cars. Nothing about tablets, or gaming consoles, probably because these two are more cost sensitive than the automotive market. But finally, we’ll see at least one tablet powered by TX1: Nabi Big Tabs. I say “tablet”, but at 55″ to 65″, it’s more like a TV with a touchscreen… Fuhu actually announced four TV sized Big Tab XL tablets. The “small” ones with 32″ and 42″ FullHD displays come with a Tegra K1, while the larger ones (55″ and 65″ / 4K UHD) are powered by a Tegra X1 processor. Here are some of the specs for the tablets: SoC Nvidia Tegra K1 quad-core Cortex A15 processor @ 2.3GHz with 192-core Kepler GPU or Nvidia Tegra X1 octa-core Cortex […]
