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, […]

Imagination PowerVR GT7900 GPU is Made for Game Consoles and Notebooks

Imaginatino Technologies has just introduced the most powerful GPU of their new PowerVR Series7 GPU family with GT7900 featuring 16 unified shading clusters and 512 ALU cores for game consoles, micro-servers, and notebooks. PowerVR GT7900 is still an embedded GPU with support for OpenGL ES 3.1 + AEP (Android Extension Pack) compatibility, full hardware support for tessellation and ASTC LDR and HDR texture compression standards. The new GPU delivers up to 800 GFLOPS (FP32) or 1.6 TFLOPS (FP16) graphics and compute performance at 800 MHz (using 16 nm FinFET+ manufacturing process), which compares to about 550 GFLOPS (FP32) for an Nvidia GeForce GT730M at comparable frequency. This is even more powerful than the Maxwell GPU found in Tegra X1 which delivers 1+ TFLOPS (FP16), although the Nvidia processor may have a lower power envelope. Combined with PowerVR Series5 decode and encode video processors and PowerVR V2500 camera processor, GT7900 can […]

Samsung Introduces Faster Full-Duplex UFS 2.0 Storage for Mobile Devices

eMMC (embedded multimedia card) provides a boost in read and write performance compared to traditional NAND flash memories, let alone micro SD cards. Samsung has now announced the manufacturing of the first 32, 64, and 128GB embedded memory solution based on Universal Flash Storage (UFS) 2.0 standard delivering up to 350MB/s read speed and 150MB/s write speed, or 40% improvement in read speed over eMMC 5.1.This should help further reduce boot time, and app loading times. Moreover, while eMMC read and write operating are sequential (half-duplex), UFS 2.0 allows for full-duplex operating, meaning writing and reading can happen at the same time. UFS can achieve this feat thanks to a LVDS (Low-Voltage Differential Signaling) serial interface with dedicated read/write paths contrary to the parallel 8-bit interface used for eMMC. Combined with a Command Queue(CQ), which sorts out the commands that needs to be carried out, UFS 2.0 allows three times […]
