Finally… An Android TV Stick with an Ethernet Port

September 30th, 2014 5 comments

Ever since MK802 hit the market in April 2012, I’ve been expecting HDMI TV Sticks with Ethernet ports, but it never really materialized. There have been many small TV boxes, but AFAIK none of which could simply be insert in the back of your TV. Thanks to MK802 V we now have an HDMI TV dongle, powered by Rockchip RK3288 quad core Cortex A12/A17 processor, featuring an Ethernet port.
MK802-VMK802 V specifications:

  • SoC – Rockchip 3288 quad core ARM Cortex A12/A17 up to 1.8 GHz with Mali-T764 GPU
  • System Memory – 2 GB DDR3
  • Storage – 8 GB NAND flash (16GB optional) + micro SD slot (up to 32GB)
  • Video / Audio Output – HDMI 2.0 (male)
  • Video Codecs – MPEG-1, MPEG-2, MPEG-4, H.263, H.264, H.265, AVS, VC-1, RV, VP6/VP8, MVC (1080p) Sorenson Spark, MVC up to 4K2K @ 60fps
  • Audio Formats – MP1, MP2, MP3, WMA, WAV, OGG, OGA, APE, FLAC, AAC, M4A, 3GPP etc
  • Connectivity – Gigabit Ethernet, dual band 802.11 b/g/n Wi-Fi with external antenna, Bluetooth 4.0
  • USB – 1x USB host ports, 2x micro USB ports (OTG + power)
  • Misc – IR extension jack (3.5mm jack), recovery button
  • Power Supply – 5V/2.5A via micro USB port
  • Dimensions – N/A

This Android 4.4.2 TV dongle comes with an HDMI cable, a USB cable, a power adapter, and a user’s manual. There’s no remote control, but I’d expect most people to use a wireless keyboard, an air mouse, or their mobile device to control Android mini PCs.

MK802 V can be purchased for $119 on Aliexpress. It’s also called Unuiga U33-4R (RK3288), and there’s a version with RK3188T.

Review of Nagrace HPH NT-V6 Android Mini PC Powered by RK3288 with 4GB RAM, 32GB Internal Storage

September 30th, 2014 4 comments

Last week-end, I finally received TP-Link TL-WDR7500 router (Chinese variant of Arched C7) router, so I could complete my review of Nagrace HPH NT-V6 including 802.11ac Wi-Fi. I’ve already listed the specifications, and taken a few pictures of the device and the board, and today I’ll focus on the test results. I’ll start by giving my first impressions, going through the user interface and settings, before testing video playback, as well as benchmarking networking, storage and overall system performance, playing some games, and testing most hardware features of this mini PC.

First Boot, Settings and First Impressions

A simple infrared remote control is provided with the device, and I’ve quickly tried it by inserting two AAA batteries, and it works fine, but for the rest of testing I switched to Mele F10 Deluxe air mouse to control the device, as it’s much more user friendly than any IR remote. Before booting up the device, I’ve connected an HDMI cable, a USB hard drive, an Ethernet cable, a USB webcam, and a USB hub with RF dongles for my air mouse and gamepad, and USB flash drive. Finally connect the power supply to boot the device in about 20 seconds.

NT-V6 User Interface (Click to Enlarge)

NT-V6 User Interface (Click to Enlarge)

The company has made their user interface, but in a similar style than the one common found in Amlogic S802 devices. On the top right, you’ve network status (Wi-Fi, Ethernet, and Bluetooth). The status bar won’t show in the main menu, but in some other apps and settings, you’ll be able to access it. A large section with 9 folders can be found on the left with Movie (Videoplayer), XBMC (yes a folder too containing XBMC, so you have to click twice), Music, Game, Browser, Stream (Youtube and Netflix), Screencast, Social and Market. On the right, you’ve got the time, and weather (that does not work), and four more icons: “My Device” (Actually a file manager), “All Apps”, “Settings”, and “All Tasks Killer”. The user interface resolution is set to 1920×1080.

The Android settings are very similar to other RK3288 TV box. The Wireless and Networks menu comes with Wi-Fi, Bluetooth, Ethernet, and Data Usage sections, as well as a “More” section with VPN, Portable Hotspot, etc… Display settings let you set the font size, adjust the screen size, select between HDMI, YPbPr (Component), and “TV” (Composite) video outputs, and the resolution: “auto”, 1080p 24/25/30/50/60Hz, 720p 50/60, 720×576 or 720×480. I don’t own a 4K UHD TV, but if I did, there should also be some 4K options. You can choose between “Default Output” (PCM), “Spdif Passthough”, and “HDMI Bitstream” (HDMI pass-through) in the Sound settings. HDMI video output is working, but composite and component (YPbPr) video outputs failed to work. An AV cable was not included, so I used some other cables, and I could only see a black screen. Audio (L/R) works fine.

What about HDMI In? I’ve connected Orino R28 meta to the HDMI input port of the NT-V6, clicked on HDMI IN app, and I could see R28 user interface, but apart from that I could not do much. Things like Android notifications of the “host” won’t show up, as as it stands the HDMI In function is just like a cheap HDMI switcher. To go back to main user interface, simply press the back key on the remote.

The version of HPH NT-V6 I got comes with a 32GB eMMC, other options includes 8, 16 or 64 GB, which is partitioned into a 1.91GB “Internal Storage” partition for apps, and a 25.99 GB “NAND FLASH” partition for data. After I installed all applications I needed for this review, I was left with 568 MB available. It would have been preferable to design the system with a single flash partition, or make the “Internal Storage” a bit bigger. Nevertheless with 26 GB for data, there’s plenty of data, even to download and place movies directly from eMMC flash.

The “About device” section only lists the model number (HPH-F0-N6) and the Android version (4.4.2). It’s running on top of Linux kernel 3.10.0, but it’s not indicated in this section. The firmware is not rooted, and NT-V6 is another device with a USB A receptacle, instead of a micro USB port, and I could not root it via the OTG port since I don’t have a proper cable. There’s a System Update app for OTA firmware upgrades, and the firmware version is currently 1.1.9 in my device. I’m not 100% sure it works, because I have not received a firmware upgrade yet.

In the video below, I boot the device, and go though the user interface, and system settings.

Google Play Store mostly works. I could install most apps, install a paid app, such as ES File Explorer, MX Player, Antutu, Beach Buggy Blitz, CPU-Z, etc…  Vidonn activity tracker app was reported as “incompatible with your device”. I discover an easy way to quickly scan through compatible apps that you’ve installed in other devices previously with the same account. Go to My Apps->All in the Play Store, and you can scroll down to see which apps are already installed, or incompatible. You can also select multiple apps, and click Install for bulk installation. Since I got Riptide GP2 as a “free app of the day”, I installed Amazon AppStore to install the game.

Power control work as it should. A short press on the remote will put the device in standby mode, and you start it again but pressing the remote button again. A long press on the power button will pop-up the Android menu with Power Off/Airplane Mode/Silent Mode, in order to achieve true power off. A press on the box button will have the same effect. When the device is powered off, you can press the remote power button, or the power button on the media player, although I’ve found the latter does not always work… It takes 3 to 4 second for power LED to run blue after pressing the power button, so it’s a bit confusing at times. and you need to wait 4 seconds to make sure you’ve really powered the device on. Both the included remote control and Mele F10 Deluxe could power on/off NT-V6. As with other RK3288 devices, the case may become hot. After Antutu benchmark, the maximum temperatures measured with an infrared thermometer on the top and bottom of the box were respectively 58°C and 64°C, and 58°C and 66°C after playing Riptide GP2 for over 20 minutes.

HPH NT-V6 mini PC is very stable, and I never had a reboot and hang up during my 6-8 hours testing. Boot time (20s) and XBMC load time (2s) are very similar to Kingnovel R6 as both integrate a fast eMMC flash.

Video Playback

Video playback results are the as Kingnovel R6 (previously known as K-R68), so I invite you to visit R6 review for video testing. To summarize, a version of XMBC 13 alpha12 is pre-installed, and suffers from not-so-smooth MPEG2 playback (in some files), lack of support for VC1, some 4K videos are not smooth at all, as well as audio/sync issues.

What’s different however is that I could play some HEVC/H.265 videos in XBMC:

  • H.265 codec / MPEG TS container (Elecard 360p / 720p / 1080p) – Audio only
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 – OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts – Won’t start to play

I’ve also test some VP9 videos. They can’t be played in XBMC, but can in MX Player:

  • out9.webm (low resolution) – OK. H/W decode according to MX Player.
  • phfx_4KHD_VP9TestFootage.webm (3840×2160) – Maybe 1 or 2 frames per second, still with H/W decode according to MX Player, but internally it’s certainly using S/W decode.

I also played a complete FullHD video (1h50) with XBMC to test stability. I had the same slow XBMC exit as with other boxes, which does not happen all the time, and apparently only during scanning or other background tasks.

Links to various video samples used in this review and be found in “Where to get video, audio and images samples” post and comments.

Network Performance (Wi-Fi and Ethernet)

To evaluate network performance, I transfer a 278 MB file between a SAMBA share and the internal flash, and vice versa, using ES File Explorer, and repeating the test three times. I now have two routers, but I’ll keep testing 2.4GHz Wi-Fi with my old TP-Link TL-WR940N router, and test 5GHz Wi-Fi with TP-Link TL-WDR7500 (Archer C7) which also support 802.11ac. I already tested NT-V6 in TL-WDR7500 review, and found the connected with NT-V6 to be unstable, and not that fast. That was on Sunday… But on Monday I tested it again, and the performance and stability was much better. I have no idea why. The only differences are: it was raining on Monday, and I was the only  one using Wi-Fi, whereas on week-ends, TL-WR940N may get 4 to 5 connected clients. So it went from 1.92 MB/s to 3.91 MB/s average speed with 802.11n, and 3.02MB/s  to 4.85 MB/s with 802.11ac, the best performance I ever got with Wi-Fi.

Throughput in MB/s

Throughput in MB/s

The top line is with 802.11ac, and the second line with 802.11n @ 2.4GHz. But as I said this chart may overestimate the actual Wi-Fi capabilities of NT-V6, and performance seem irregular… Using “sunday” results, 802.11ac would have been in third position in the chart, and 802.11n between Vega S89 and AV200.

And now Ethernet…. I had rather disappointing performance with Fast Ethernet, and still more problems with Gigabit Ethernet… I should really buy another Gigabit switch to make sure that’s not the root cause.

Fast Ethernet Performance in MB/s

Fast Ethernet Performance in MB/s

I could actually get a Gigabit Ethernet connection, but I got a transfer rate of 250 KB/s from network to flash, and 1.8MB/s from flash to network…

In order to get a “pure” network test, I also used iPerf app and iperf in my Ubuntu PC, using “iperf -t 60 -c -d” command line in Android. It clearly show some issues with both Fast and Gigabit Ethernet, and whereas one direction has good performance, the other is problematic (100Mbps first, then Gigabit):

Client connecting to, TCP port 5001
TCP window size: 85.0 KByte (default)
[  6] local port 35429 connected with port 5001
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-60.1 sec   672 MBytes  93.8 Mbits/sec
[  6]  0.0-60.1 sec  81.0 MBytes  11.3 Mbits/sec
Client connecting to, TCP port 5001
TCP window size: 85.0 KByte (default)
[  6] local port 35764 connected with port 5001
[  4]  0.0-60.0 sec  6.16 GBytes   882 Mbits/sec
[  6]  0.0-60.9 sec  16.5 MBytes  2.27 Mbits/sec

Miscellaneous Tests


File transfer over Bluetooth works fine. I use ThL W200 Android smartphone to send a picture to NT-V6.

I skipped Sixaxis test for PS3 Bluetooth Gamepad support, because the firmware is not rooted, and I’m not sure how to root it without OTG cable.

Vidonn X5 activity tracker was used to test Bluetooth 4.0 LE. I could not install Vidonn app from Google Play (incompatible), so I instead installed vidonn.apk, and successfully connected to my wristband to get the data. Note-to-self: make sure to set the time on the mini PC before making the connection to the wristband, or it will mess with the data…


The system could detect and mounted a micro SD card and USB flash drive formatted with FAT32.
It seems nobody is interested in having EXT-3/4 working for external storage in Android, and as usual only the NTFS and FAT32 partitions on my USB 3.0 hard drive could be mounted.

File System Read Write
EXT-4 Not mounted Not mounted
BTRFS Not mounted Not mounted

I benchmarked the eMMC and the NTFS partition on my hard drive with A1 SD Bench. There does not seem to be a standard for mount points in Android, and firmware from various (SoC) vendors, have different mount points. In this firmware, the NTFS partition is located in /mnt/usb_storage/USB_DISK2/USB3_NTFS. The read speed was 35.62MB/s, and the write speed of 15.08MB/s, so NT-V6 gets both the best read speed, and the worst write speed of all devices I tested.


USB NTFS Performance in MB/s

Hopefully, the only solution is some optimization for NTFS writing speed.

The Samsung eMMC found on the board has very good performance, reading at 55 MB/s, and writing at 18 MB/s.



Beside fast loading times, a product with a fast eMMC is much less likely to experience slowdowns.

USB Webcam

I could test audio successfully with the Echo service in Skype, but unfortunately although my webcam appeared to be detected in both Skype and Google Hangouts, I could only see a black screen during video calls.


Candy Crush Saga, Beach Buggy Blitz, and Riptide GP2 all worked pretty well. I played Candy Crush Saga with Mele F10 Deluxe, and the two racing games with Tronsmart Mars G01 wireless gamepad. Beach Buggy Blitz is super smooth all the time, even after maxing out graphics settings. Riptide GP2 is very playable as well, but not optimal all the time, but clearly mini PCs based on Rockchip RK3288, and much better than the rest of Chinese Android mini PCs thanks to its Mali T-764 GPU. I played the latter game for over 20 minutes to test stability, and I did not encounter any specific issues. Temperature measurements after game: 58°C (top) and 66°C (bottom).

Nagrace HPH NT-V6 Benchmark

CPU-Z app returns similar data as other TV boxes with Rockchip RK3288 processor being a four Cortex A12r0p1 core processor with a Mali-T764 GPU, except this time, the CPU frequency is between 312 MHz and 1.61 GHz, instead of topping at 1.8GHz for other devices.. I could also check there’s indeed 4GB RAM installed with over 2700 MB free.HPH_NT-V6_CPU-Z

NT-V6 could achieve G1H got 35,321 points in Antutu 5.1, a bit lower than Kingnovel R6 score (37,428), most probably because of the lower CPU frequency.


I had not run Vellamo 3.x  test in R6 media player, but the scores in NT-V6 are better than the ones for Uyesee G1H.


Ice Storm Extreme benchmark score (7,056) in 3DMark is however a bit lower than the two other RK3288 box I tested (7,278 and 7,531).

Nagrace HPH NT-V6 is a pretty good hardware with a fast processor, excellent 3D and eMMC storage performance. The firmware is stable, and provides a smooth user experience, without slowdowns. Wi-Fi can be excellent too, but stability may be an issue. As with other Rockchip RK3288 devices I’ve tested,  video playback in XBMC is rather disappointing, but at least there’s partial HEVC/H.265 codec support. partial, nbecause only some caontainers appear to be supported.


  • Fast new processor
  • Excellent 3D graphics performance for games
  • Stable and fast firmware.
  • Memory and Storage capacity (4GB / 32GB)
  • Excellent Wi-Fi performance, when it works
  • Fast eMMC, both for reading and writing speeds.
  • Both 720p and 1080p user interfaces are supported
  • Video Output – 1080p support 24, 25 ,30 , 50 and 60 Hz output. 4K @ 60Hz should be supported (not tested).
  • Partial HEVC/H.265 video decoding support in XBMC.
  • OTA update appear to be support
  • Proper power off/standby handling.
  • HDMI In


  • XBMC has too many issues: VC1 not supported, H.265 support only partial, audio/video sync issue, some MPEG-2 and XVID videos are skipping frames, some of the 4K videos I used could play properly, etc…
  • Some MPEG-2 file won’t play smooth in either XBMC or MX Player
  • Potential Ethernet issues, confirmed with my Gigabit switch (D-Link DSG-1005A) and 10/100Mbps D-Link router (configured as a switch).
  • Video output – Component and composite do not work atall (black screen)
  • Webcam not working properly (black screen) in Skype and Hangouts
  • Relatively slow write speed on NTFS/USB partition.
  • Wi-Fi may be unstable at times
  • HDMI In support is quite basic (only as HDMI switcher)

HPH NT-V6 with 4 GB RAM and 32 GB eMMC (as reviewed in this post) purchased for $189 including shipping by DHL or EMS, but there’s also a 2GB RAM/16GB eMMC available on Aliexpress for $129 + shipping. I’ve also been told Ugoos UT3 is based on the same board (TRN6A), but should have a different firmware. It is listed on Chinavasion for $149.99, and DealsPrime for $134.99 (bot 2GB/16GB versions). Resellers and distributors can check out Nagrace NT-V6 product page to order in quantities.

FVIEW U2 Rockchip RK3188 Media Player with 2GB RAM, Ethernet, and Camera Sells for $53

September 29th, 2014 9 comments

If you are looking for deals, when new products come to market, older devices are usually sold at a deep discount, and sometimes you also have the advantage of getting a firmware that has gone through various iterations, and that’s  more stable than the ones pre-loaded on new devices. We’ve already seen MK813 quad core TV box selling for less than $50, but it lacks Ethernet, and today I’ve been informed of another Rockchip RK3188 device with similar specifications but with an Ethernet port called FVIEW U2 that’s currently selling for $53 on Buyincoins.


  • SoC – Rockchip RK3188 quad Cortex-A9 CPU @ 1.6 GHz + Mali-400 MP4 GPU
  • System Memory – 2GB DDR3
  • Storage – 8GB NAND Flash +  micro SD slot (Up to 32GB)
  • Connectivity
    • 10/100M Ethernet
    • WiFi 802.11 b/g/n with external antenna
    • Bluetooth 3.0
  • Video Output – HDMI
  • Audio Output – HDMI + optical S/PDIF
  • Video Codecs (Decode) – MPEG-1, MPEG-2, MPEG-4, H.263, H.264 (up to 60 Mbps), AVS, VC-1, RV, VP6/VP8, Sorenson Spark, MVC @ 1080p60
  • Video Codecs (Encode) – H.264, VP8, and MVC @ 1080p
  • Audio Codecs – MP1, MP2, MP3,WMA,WAV,OGG,OGA,APE,FLAC,AAC,M4A,3GPP…etc
  • Camera – 2MP camera
  • USB – 3x USB host ports
  • Misc – IR port, recovery button, power button
  • Power – 5V/2A
  • Dimensions – 13.60 x 13.60 x 2.4 cm

This Android 4.4 box is sold with an infrared remote control, a USB cable, a power adapter, and a user’s manual. So no HDMI cable based on the description, but according to a picture on Buyincoins, you’d get an HDMI cable, and no USB cable. I’ve been looking if the device was popular and had some supports on the Internet, but no luck, and I could not find the firmware either. Somebody provided a link to pictures of the board, which could could a clue to the hardware and alternative firmwares, but Google Drive asks for permissions, and I haven’t been able to access them yet. The company that made the box is called Shenzhen Firstview Electronics, but there’s nothing in their download section at all.

Firefly-RK3288 Development Board is Now Available for $189

September 27th, 2014 2 comments

Three days ago, a T-chip representative informed me privately that Firefly development board (Rockchip RK3288) would not be available on foreign websites, and that it was unclear when the board would be selling in China. So either I’ve been lied to, or there’s poor internal communication within the company, as they’ve now listed Firefly-RK3288 board on Taobao for 800 CNY (~$130), and it’s also available on Ebay for $189 including shipping, possibly by somebody unrelated to T-chip, especially there are only 3 units for sale.

Firefly_Development_BoardLet’s go the specifications that have slightly changed since the original announcement:

  • SoC – Rockchip 3288 quad core ARM Cortex A12 / A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1
  • System Memory – 2G DDR3
  • Storage – 16 GB eMMC flash + micro SD slot
  • Video I/O
    • HDMI 2.0 up to 3840×2160@60p
    • VGA out (D-SUB connector)
    • Dual MIPI, Dual LVDS and and EDP signal available via expansion headers
  • Audio Output / Input – HDMI, optical S/PDIF, microphone header, and built-in MIC
  • Connectivity – Gigabit Ethernet, dual band 802.11 b/g/n and 802.11ac Wi-Fi with external antenna, and Bluetooth 4.0
  • USB – 2x USB 2.0 host ports, 1x micro USB OTG
  • Debugging – Serial console
  • Expansion Headers – 2x 38-pin headers with access to MIPI, LVDS, EDP, SPI, UART, ADC, GPIO, I2C, I2S…
  • Misc – IR receiver, 2x user LED, power, recovery and reset buttons.
  • Power Supply – 5V/2A
  • Dimensions – 118 x 83 mm

The board ships with a USB cable and a Wi-Fi antenna. An acrylic enclosure and a 5V/2A power adapter are available as option. The company has now updated their Wiki in English with a quick start guide, hardwre document and instructions to build Android and Linux from source. You can also download Android 4.4 and Ubuntu (Lubuntu) 14.04 Desktop images, or a dual boot Android/Ubuntu image.

Since the board is $130 on Taobao, and $189 on Ebay, you may be able to save a few bucks by buying via Taobao from third party websites such as taobaoring or engtaobao. According to a post by Charbax, it might also be possible to get it shipped for $159, but contacting the company by email, but of course in that case, you don’t have third party protection. Such board is mostly interesting since you’re hopefully getting an up-to-date SDK for the board, but if you are simply looking for devices with these features, something like Tronsmart Orion R28 Meta would be cheaper.

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

September 27th, 2014 No comments

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4.

Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month.

Here are the highlights of this release:

  • Linux Linaro 3.17-rc4-2014.09
    • GATOR version 5.19
    • updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT
    • updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT.
    • updated Versatile Express patches from ARM LT
    • updated LLVM topic (follows the community llvmlinux-latest branch)
    • Big endian support (the 2014.05 topic version rebased to 3.17 kernel)
    • config fragments changes – added gcov config fragment, disabled DRM_EXYNOS_IOMMU to work around boot failure on Arndale
  • Linaro Toolchain Binaries 2014.09
    • based on GCC 4.9 and updated to latest Linaro TCWG releases: Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, and Linaro GDB 7.8-2014.09.
    • This will be the last release done with cbuild1 and crosstool-ng. Next releases will be done with cbuild2. Official support for very old host environments will be dropped.
  • Linaro builds of AOSP 14.09 built with Linaro GCC 4.9-2014.09.
  • Linaro OpenEmbedded 2014.09
    • integrated Linaro GCC 4.9-2014.09, Linaro binutils 2.24-2014.09, integrated Linaro GDB 7.8-2014.09.
    • imported Linaro eglibc 2.19 into meta-linaro after OE-core switched to glibc 2.20
    • fixed shadow securetty for Qualcomm and STMicroelectronics SoCs
    • upstreaming – fixed libpng on aarch64 (neon symbol), updated PM QA to 0.4.14, updated libunwind to include aarch64 support
  • Linaro Ubuntu 14.09
    • added linux-tools (perf standalone, splitted from kernel build)
    • updated packages: Juno firmware 0.8.1, LSK 3.10.55/3.14.19 and linux-linaro 3.17-rc4 kernels.
  • A gcov enabled build has been added
  • Linaro builds of the Android NDK have been updated to current upstream sources and current Linaro toolchain component releases.
  • Standalone Android toolchain binary builds now use Linaro binutils for improved armv8 support.

You can visit for a list of known issues, and further release details about the LEB, LMB (Linaro Member Builds), and community builds, as well as Android, Kernel, Graphics, Multimedia, Landing Team, Platform, Power management and Toolchain components.

Howchip Introduces ExSOM-4412 Module and Development Kit Powered by Samsung Exynos 4412 Quad Core SoC

September 24th, 2014 2 comments

Howchip, the company that normally distribute Insignal Origen and Arndale boards, has just introduced ExSOM-4412 system-on-module, and a corresponding development kit called ExSOM-4412-DVK.

ExSOM-4412-DVKExSOM-4412 module specifications:

  • SoC – Samsung Exynos 4412 quad core Cortex A9 CPU with Mali-400MP4 GPU
  • System Memory – N/A (TBC)
  • Storage – Up to 8GB eMMC + SD/SDIO interface
  • Connectivity – 10/100Mbps Ethernet, optional  Wi-Fi and Bluetooth module
  • Video Output – HDMI(1080p) for TV, 2-ch LVDS for TFT LCD
  • Camera – 2x parallel camera interfaces
  • Audio – Line in/out  and Headphone out.
  • USB – 4x USB 2.0 Host ch and OTG
  • Configurable GPIOs, Analog inputs, PWMs and Serial interfaces such as I2Cs, SPIs,  and UARTs
  • SoM Connector – 213-pin MXM connector
  • Dimensions – 70mm x 70mm

The dimensions and connector used points to the module following Qseven standard, but the company does not mention anything about Qseven, so the pin assignment may be different. Software support is a bit disappointing with only Android 4.0.4 with Kernel 3.0.x available, including full source code.

For evaluation and development ExSOM-4412-DVK kit is provided with the SoM and a nano-ITX (120×120 mm) baseboard with the following connectors:

  • External Storage – micro SD slot
  • Video Output – HDMI and LCD interface
  • Connectivity – Ethernet (RJ45) and Wi-Fi/BT (via SoM)
  • Audio – Line-out, Line-in
  • USB – 2x USB 2.0 host ports, 1x micro USB OTG port, 2x USB 2.0 host via headers
  • Serial – UART 1 & 2 via headers
  • Expansions Header – 2x 20-pin header for GPIO/I2C/SPI
  • Misc – Sleep, power and reset buttons, “debug” port
  • Power – 12V power barrel, battery connector

It’s unclear what the two yellow RCA connectors on the right of the board are for. Maybe video out (composite) and in? Schematics & CAD files are said to be available for the baseboard.

ExSOM-4412L can be purchased now for $89 without Wi-Fi/BT module, and $99 with the wireless module (ExSOM-4412), and the full development kit goes for $199, shipping costs via Fedex are not included. Delivery is scheduled in four weeks time. You can visit Howchip’s ExSOM-4412 page to order the module and/or development kit, but technical details are sparse for now.

Rockchip RK3126, RK3128, and “MayBach” Octo-core Cortex A53 Processor Could Be Found in Tablets in Q4 2014

September 24th, 2014 4 comments

T-chip, the company behind Firefly-RK3288 development board and HPH NT-V6 media player, has sent me their latest company brochure this morning. The brochure mentions the company history since 2005, various tablets solutions they have done over the year, and new and upcoming products. One of the slides particularly caught my attention.

Rockchip_RK3128_RK3126_MayBachRK3288 is pretty popular right now, but I had never heard about RK3126 and RK3128 SoC with four ARM Cortex A7 core with a Mali GPU supporting HEVC decoding up to 1080p resolution. Both processors are manufactured using 40nm technology, so I’d guess these target ultra low cost tablets, which should become available in October and November 2014.

Even more interesting is the mention of “MayBach” Tablets. I’ve been told MayBach, which could just be a temporary codename, is an upcoming Rockchip SoC. Based on the information in the slide, it should be an Octa-core Cortex A53 processor with an unnamed GPU supporting OpenGL ES 3.0. Supported features include 4K/H.265 video decoding, HDMI 2.0 / LVDS / DSI / eDP video outputs, and an ISP with CSI2 camera interface(s).

I could not find more information about a Rockchip Cortex A53 on the web, except that Rockchip licensed Cortex A50 cores in November 2013.

Separately, I’ve also asked T-Chip about Firefly-RK3288 availability, and that’s what I’ve been told:

Firefly demoboard won’t purchase online on foreign website and the time when it will purchase online inland is not determined.

Disappointing. This conflicts with new that the board would be listed on Taobao next week. so if you want the board, you may have to order by email ($129 + shipping), as mentioned by Charbax, or simply wait for Radxa Rock 2 instead.
