Beaglebone: The Perfect Telemetry Platform? – ELCE 2012

Matt Ranostay, technical staff at Ranostay Industries, gives a presentation about a telemetry system based on Beaglebone at the Embedded Linux Conference Europe on November 5, 2012. Abstract: The author will discuss his ongoing and other team members efforts to develop hardware and software that reports sensor data to the community. This talk will be split into several parts a) types of useful sensors b) hardware design of Beaglebone capes c) and telemetry reports to Pachube/Cosm. Demonstrating that in the new world of cheap prototyping boards with I2C, GPIO, and SPI that anyone can setup a decent monitoring system for home security, automation, and weather reporting. There will be a live demo of prototype geiger counter + weather station. The audience targeted is the professional hobbyist who likes to hack on microcontrollers in their spare time. It will take little to medium knowledge of electrical engineering to follow this talk. […]

F2FS – A New Flash File System for Mobile Devices – ELCE 2012

Joo-Young Hwang, principal engineer at Samsung, presents F2FS (Flash-Friendly File System), a new file system designed for storage in mobile devices at the Embedded Linux Conference in Barcelona, Spain, on November 5, 2012. Abstract: Recent mobile devices adopt various flash storages as a primary storage. File system support for those flash storages is a must for flash device performance and lifespan. I will present a new file system, called F2FS, designed for mobile flash storages. F2FS is designed considering the characteristics of the underlying flash storage which has flash translation layer (FTL). F2FS outperforms EXT4, which is a popular file system for Android phones, in most of benchmarks. I will describe motivation, design, and implementation of the file system, then show performance comparison data with EXT4. Target audiences are those who are interested in file system support for flash storages such as eMMC and SSD. Kernel and file system expertise […]

Inside Android’s User Interface – ELCE 2012

Karim Yaghmour, Opersys inc, talks about the internals of the Android user interface at Embedded Linux Conference Europe on November 5, 2012. Abstract: Android is a very complex stack comprising several dozens of novel components and moving parts. Still, it’s intrinsically a user-centric system and, therefore, its parts which deal with user interface are of special interest for anyone aiming to put Android in a device. This talk will examine the internals of Android’s user-facing components. Specifically, we will cover the inner-workings and interactions of the Window Manager, Surface Flinger, Input Method Manager, and the rest of the system. We will also cover key display and input components such as the Status Bar, Soft Keyboard and Notifications. This talk will be especially useful to developers intending to use Android in user-facing embedded systems, those needing to implement support for their graphics hardware and anyone interested in the internals of Android’s […]

Etnaviv Project Vivante GCxxx GPU Open Source Driver

You have most probably heard of Lima, an initiative to provide fully open source Mali-200 & Mali-400 drivers by reverse-engineering the closed source Mali GPU drivers. A separate effort, Etnaviv Project, has now started to offer open source drivers for Vivante GCxxx GPU used in SoC such as Marvell Armada 1500 (notably used in mainly Google TV platforms), Rockchip RK2918 (present in many older tablets),  Freescale i.MX6 (used in newer tablets, low cost development boards, some SoMs and GK802/Hi802 mini PCs). The project is called Etnaviv. The introduction of Etnaviv Project reads as follows on the corresponding Github account: Project Etnaviv is an attempt to make an open source user-space driver for the Vivante GCxxx series of embedded GPUs. The current state of the project is experimental. It is currently only of use to developers interested in helping develop open source drivers for the hardware, reverse engineering, or in interfacing […]

Rockchip Shows Off RK3188 Quad Cortex A9 Processor and Miracast Dongles

There has been some leaks about Rockchip RK3188 processor, and Cube Pea tablet based on this SoC, but no device are available for purchase to date. Rockchip is currently at CES 2013 showcasing their solutions, and they are showcasing RK3188 tablet development platform at the show, but no RK3188 tablet as final products should only start to be available in March. Charbax is at CES 2013 now, and could ask a few questions about Rockchip upcoming SoC. RK3188 is a quad core Cortex A9 processor clocked up to 1.8-2.0 GHz, manufactured using 28nm HKMG process technology. The SoC features a quad-core Mali-400MP GPU,  1080p video decoder & encoder, and they can easily provide 4G/LTE support. RK3188 should be 20 to 30% faster than Nvidia Tegra 3, and have the same performance as Samsung Exynos 4412. Rockchip representative also stress that performance/cost ratio will be better than (Chinese) competitor basing their […]

QNX CAR 2.0 Demo and Texas Instruments OMAP5 Jacinto 6 Processor

There’s a Bentley GT concept car at CES 2012 to demonstrate QNX CAR 2.0 platform that provides dual screen support with the dashboard and an infotainment display for the automotive industry. Under the hood, the platform features TI DLP technology, and TI OMAP5 and Jacinto processors running QNX Neutrino RTOS. Texas Instruments and QNX uploaded a video demo of the concept on YouTube. They explain that they switched their platform from HTML5 to native OpenGL for optimal performance using Storyboard Suite from Crank software, and they can now show 3D maps smoothly on the platform. The 1080p user display is curved to be more user friendly (better touch angles). You must have certainly heard about touchscreens before, but maybe never heard about “pretouch”. Pretouch is a feature of the system that detect when you hand comes close to a control virtual and pops up a virtual menu. The dashboard shows […]
