Meizu MX4 Ubuntu Edition Octa-core Smartphone to be Unveiled at MWC 2015

BQ Aquaris E4.5 Ubuntu Edition may have been the first phones launched with Ubuntu operating systems, but the device is rather an entry-level smrtphone with Mediatek MT6582 quad core Cortex A7 processor and 1GB RAM. If you’d like a much faster and powerful Ubuntu phone, Meizu MX4 Ubuntu Edition will be announced at Mobile World Congress 2015. The specs has not been disclosed yet, but it’s highly likely the hardware will be the same as the Android version of Meizu MX4: SoC – MediaTek MT6595 octa core processor with 4 Cortex A17 @ 2.2GHz, and 4 Cortex A7 @ 1.7GHz in big.LITTLE configuration with a PowerVR G6200 GPU. System Memory – 2GB dual-channel LPDDR3 RAM, 933MHz Storage – 16, 32, or 64GB eMMC Display – 5.36″ IPS touchscreen; 1920×1152 resolution; Corning Gorilla Glass 3 Camera – 20.7MP rear camera with dual tone LED flash, 2MP front-facing camera Audio – 3.5mm […]

Build a Raspberry Pi 2 Minimal Image with The Yocto Project

The Yocto Project is a build system that allows developers to make custom Linux distributions matching their exact needs. I’ve already shown how to build a 12MB Compressed image for the Raspberry Pi with Yocto, but the Raspberry Pi 2 has recently been added to the project, so I’ve tried to build it too in a machine running Ubuntu 14.04. I’ll use poky since it’s the default, but you could also build the system for Angstrom or without distributions (OpenEmbedded Core only). The steps to get the code is just the same as for the Raspberry Pi:

mkdir yocto
cd yocto
git clone git://git.yoctoproject.org/poky.git
cd poky
git clone git://git.yoctoproject.org/meta-raspberrypi

mkdir yocto

cd yocto

git clone git://git.yoctoproject.org/poky.git

cd poky

git clone git://git.yoctoproject.org/meta-raspberrypi

You just need to checkout master, and not any branch (like dizzy) since R-Pi 2 is not yet supported in any release. Initialize some environment variables and the build directory:

. oe-init-build-env build

1	. oe-init-build-env build

Now edit conf/local.conf with vim or nano to set the machine to raspberrypi2 instead of qemux86:

MACHINE ??= "raspberrypi2"
GPU_MEM = "16"

1 2	MACHINE ??= "raspberrypi2" GPU_MEM = "16"

There are more Raspberry […]

Zsun Wifi Card Reader Adds up to 64GB to Your Smartphone

I’ve previously covered Zsun SD11x USB flash drives with 8 to 128 GB internal flash, a battery, and Wi-Fi connectivity in order to easily add storage to devices without micro SD slots. The company has now launched a new Wi-Fi card reader to do the same, but with your own micro SD card instead allowing up to 64GB extra storage, and easy replacement. Zsun card reader specifications: SoC – Qualcomm Atheros AR9331 WiSoC System Memory – 256 Mbit RAM (32 MB) Storage – Internal flash for firmware (capacity TBD), micro SD slot up to 64GB Connectivity – 802.11 b/g/n Wi-Fi @ 150 Mbps USB – 1x USB 2.0 port for power and use as standard USB card reader Dimensions – 33 x 30 x 13 mm There’s no battery, so you’d have to connect the dongle to a power bank, PC, car charger etc.. to power it. If you connect […]

Linaro 15.02 Release with Linux 3.19 and Android 5.0

Linaro 15.02 has just been released with Linux 3.19 (baseline), Linux 3.10.68 and 3.14.34 (LSK), Android 5.0.2, and Ubuntu Linaro Utopic. Listed changes for Linux Linaro are exactly the same as last month, except they’ve used Linux 3.9 release. Power management tools have been added to their AOSP build, and some work has been done for Android 5.0 on the new Hikey board. Here are the highlights of this release: Linux Linaro 3.19-2015.02 GATOR topic: version 5.20.1 updated integration-linaro-vexpress64 topic by ARM LT (FVP Base and Foundation models, and Juno support) updated topic from Qualcomm LT (ifc6410 board support) updated topic from HiSilicon LT (Hi36xx, HiP04, and X5HD2 families support) updated LLVM topic (the community llvmlinux-latest branch) included ILP32 patch set v3 rebased onto 3.19. Initial tests using syscalls LTP tests done. When using ILP32 userland, a few tests have to be skipped (msgctl07, msgrcv0[1-7], msgsnd01) to avoid the stalls, […]

Console OS Developer Preview Image Released for Some Intel Haswell and Bay Trail Systems

Console OS is an operating system based on Android that’s designed to run on x86 machines side-by-side with Windows and with desktop-friendly user interface. The project has been funded via a Kickstarter campaign, so backers get the updates earlier, but the developers have now publicly released Console OS DR1 (Developer Release 1) based on Android 4.4.2 so that more people can download it and try it for free after registration. I wanted to try it on Mele PCG03, but it failed, even after copying bootia32.efi to /EFI/BOOT directory (I get stuck into Grub command line), and I found out that “Systems must have 64-bit UEFI firmware. Some systems have 32-bit UEFI firmware, and we are working on adding support for those provided you have one of the processors above”. So it won’t work on cheap Windows 8.1 dongles and mini PC like MeegoPad T01 or Pipo X7, but MINIX NEO […]

Allwinner’s New Media Codec Library (CedarX) May Infringe on Open Source Licenses and Copyrights

Allwinner has had to good idea to open allwinner-zh github account last September in order to release source code, binary libraries, and documentation for these ARM processors. Yesterday, the company released a new version of their closed source CedarX library used to decode and encode video streams. But Luc Verhaegen (libv), known for his reverse-engineering work on ARM Mali-400 (lima driver) and now Mali-Txxx GPU (Tamil driver), analyzed the binary and claimed the library is not compliant with LGPL licenses, and may also infringe on On2 copyrights. Luc wrote his concerns on sunxi-linux mailing list, and Allwinner promised to look into it. Two libraries are involved: ffmpeg which includes both LGPL and GPL licenses, but the contention seems to be about the LGPL part, since only optional features are GPL’ed in ffmpeg. It’s perfectly fine to include LGPL libraries into your binaries, as long as you don’t modify the open source […]

GroBotz Interactive Robot Project is Made of Easy to Assemble Smart Blocks (Crowdfunding)

GroBotz makes me think of Lego applied to robotics. The project consists of modules such as motors, sensors, buttons, switches, or cameras that snap together in order to create a robot on wheels, games, toys, a musical instrument, or whatever idea you may have, and the hardware is then programmed using a graphical user interface. A Raspberry Pi board is used for the brain of the robot, and Microchip PIC MCUs for the smart blocks. The software is programmed in C# using Xamarin, the user interface is based on Unity, OpenCV is used for image processing, and during development a plastic part where printed with Makerbot, and schematics and PCB layout designed with CadSoft EAGLE. The company has now come up with a number of modules as shown in the picture below. Your robot can then be controlled over Wi-Fi with GroBotz app which works on Windows, Mac OS, iOs, […]

UDOO Neo Development Board is Powered by Freescale i.MX 6SoloX Processor

UDOO boards combine a Freescale i.MX6 dual or quad core processor with an external Atmel SAM3X MCU that’s programmable as an Arduino board, so as Freescale has now formally announced their i.MX 6SoloX processor with a Cortex A9 core running Linux and Android, and a Cortex M4 core running MQX real-time operating systems, it was logical that the company would soon launch a low cost development board based on this heterogeneous processor. Meet UDOO Neo. UDOO Neo board specifications: SoC – Freescale i.MX 6SoloX ARM Cortex-A9 core @ 1GHz and ARM Cortex-M4 Core with 2D/3D GPU System Memory – 512MB or 1GB DDR3 (only Plus version) Storage – On-board NOR SPI Flash, micro SD slot, 8-bit SDIO interface (on headers) Video Input/Output micro HDMI port LVDS interface + touch (I2C signals) Analog camera connection supporting NTSC and PAL 8-bit Parallel camera interface (on headers) Audio – HDMI USB – 1x […]
