Free Electrons Publishes Yocto & OpenEmbedded Training Materials

Free Electrons is a small (9 people) engineering company focusing on embedded Linux / Android, and open source software, which also happens to have ported several ARM SoC to the mainline kernel. From time to time, they also offer training sessions, and release course materials publicly. Their latest training is a 3-day course dealing with the Yocto Project and OpenEmbedded, using BeagbleBone Black development board for lab sessions, and all materials have been released under a Creative Commons license. The training consists in: Understanding the Yocto Project Using it to build a root filesystem and run it on your target Writing and extending recipes Creating layers Integrating your board in a BSP Creating custom images Application development with an Eclipse SDK Three files are released: yocto-slides.pdf – Yocto Project and OpenEmbedded Training presentation slides (245 pages) give an overview of various build systems, before getting more details about the Yocto […]

Unboxing of Rippl-TV XBMC Android Media Player

Half year ago, I reviewed Shenzhen Tomato M8 / TM8 Android TV Box. It was the first hardware I received based on Amlogic S802, and although I found overall performance and video playback in XBMC was very good, the firmware was not always stable, and Wi-Fi performance was poor. Shenzhen Tomato has now sent me another model based on Amlogic S802 called Rippl-TV (click for full specs), with an hardware very similar to M8 as we’ll see below, but a completely different firmware that relies on XBMC as the Android launcher. Rippl-TV Unboxing I received the TV Box by Fedex in the following package that reads “Rippl-TV a drop of perfection brings out the best in media…” The package lists the key features of the TV with 4K UHD video playback, XBMC Rippl-TV Edition, Android 4.4 OS (called UtilOS), dual band Wi-Fi, a quad core Cortex A9 CPU coupled with […]

ARM Unveils Embedded Systems Education Kit Based on NXP LPC4088 Cortex M4 MCU

Following up on their first “Lab-In-a-Box” initiative based on Micro STM32F4-Discovery board and Wolfson audio card, ARM launched another low-cost toolkit, based on Embedded Artists LPC4088 QuickStart and Experiment boards, and called “Embedded Systems Education Kit”, to help university educators teach embedded systems design and programming concepts. The kit includes the following hardware, software tools, and teaching materials: Embedded Artists LPC4088 QuickStart Board and LPC4088 Experiment Base Board ARM Keil MDK-ARM Pro microcontroller development suite software licences Complete teaching materials including lecture note slides, demonstration code and hands-on lab manuals with solutions in source for four embedded system courses: ‘Efficient embedded systems design and programming’ teaches microcontroller fundamentals using NXP’s 32-bit ARM Cortex-M4 based LPC4088 microcontroller. ‘Rapid embedded system design and programming’ delivers embedded systems design training for the high-level ARM mbed API ‘OS design’ uses the royalty-free ARM Keil RTX RTOS to show how to design, program and optimize […]

Linaro 14.10 Release with Kernel 3.17 and Android 4.4.4, Debian ARM64 Port Almost Complete

Linaro 14.10 has just been released with Linux kernel 3.17 (baseline), Linux 3.10.54 & 3.14.19 (LSK, same versions as last month), and Android 4.4.2 & 4.4.4. Most of the work is a continuation of previous months working member hardware, and ARM64, but one particularly interesting point is that 90% of Debian packages have been built for ARM64, and the next version of Debian should have an official ARM64 port. Here are the highlights of this release: Linux Linaro 3.17-2014.10 updated linaro-android topic. In particular, CONFIG_IPV6=y is no longer the requirement for linux-linaro tree builds GATOR version 5.19 (same version as in 2014.08 release). gatord is fixed to build for ARMv8. dropped multi_pmu_v2 topic by ARM LT (no longer used) updated topic from Qualcomm LT (include IFC6410 board support) replaced integration-linaro-vexpress topic by integration-linaro-vexpress64. Starting from 2014.10 release, linux-linaro kernel tree will use the mainline support for 32-bit vexpress boards. integration-linaro-vexpress64 […]

MIPI Introduces SoundWire Audio Interface for Mobile Devices

MIPI (Mobile Industry Processor Interface) Alliance is a non-profit corporation that establishes standards for hardware and software interfaces in mobile devices. MIPI is better known for its MIPI DSI (Display Serial Interface) and CSI (Camera Serial Interface), but as you can see from the diagram below, they’ve been busy publishing a lot more interface specifications. The latest being MIPI SoundWire, a new audio interface for amplifiers, microphones and audio codecs used in smartphones, tablets, mobile PCs and other devices. The consortium only released a “MIPI SoundWire Specification Brief” so there aren’t that many details. SoundWire is not the first audio interface from MIPI, with SLIMbus having been first introduced in 2007, and later updated in 2013 with SLIMBus 1.1. SLIMbus must not have been that widely used, as only Intrinsyc OPEN-Q 8084 Development Kit appears to feature the interface among all the board listed on CNX Software. Nevertheless SLIMBus and […]

Qualcomm Releases Userspace Adreno 320 GPU Drivers for Ubuntu

Qualcomm Developer Network has just sent the October Newsletter by email, and they had some news specific to Ubuntu / Linux support on IFC6410 development board powered by a Snapdragon 600 processor. Firs they link to a guest blog post on Qualcomm website entitled “Video Conferencing on Linux with the Qualcomm Snapdragon 600 Processor“, where Qualcomm partner eInfochips stated: Qualcomm Technologies, Inc.’s leadership in mobile market with Linux Android support is well established. As the demand for Qualcomm Snapdragon processors, a product of Qualcomm Technologies, Inc., increase in adjacent markets, the need for non-Android Linux support becomes evident. Which is always good to read. The rest of the post blog provides a few more details about their a low-latency (50ms glass-to-glass) video conferencing solution based on OpenEmbedded build with Linaro Linux Kernel, and making use of Qt5, Gstreamer, and Sofia SIP library. Further improvements will be achieved with hardware video […]

Applied Micro X-Gene (64-bit ARM) vs Intel Xeon (64-bit x86) Performance and Power Usage

A group of researcher at CERN have evaluated Applied Micro X-Gene 1 64-bit ARM XC-1 development board against Intel Xeon E5-2650 and Xeon Phi SE10/7120 systems, and one of them, David Abdurachmanov, presented their findings at ACAT’ 14 conference (Advanced Computing and Analysis Techniques) by listing some of the issues they had to port their software to 64-bit ARM, and performance efficiency of the three systems for data processing of High Energy Physics (HEP) experiments like those at the Large Hadron Collider (LHC), where performance-per-watt is important, as computing systems may scale to several hundred thousands cores. Intel Xeon Phi platform based on Many Integrated Cores (MIC) computer architecture was launched the HPC market, and contrary to the table above features 61 physical cores. Applied X-Gene 1 (40nm process) was used instead of X-Gene 2 built on 28-nm process which was not available at the time. The ARM platform ran […]
