Most tablets on the market either run Android or Windows, and while some have tried to launch Linux tablets, none of the products have really caught on, although the upcoming PINETAB might change that. Another option might be Ntablet 7″ tablet that runs either Android, Debian or WebOS Linux operating systems, but also offers some innovative features such as a replaceable Rockchip RK3288 CPU module, and an external GPIO board for makers. Ntablet hardware specifications: SoC – Rockchip RK3288 quad-core Cortex-A17 processor @ 1.8 GHz with Mali-T760 quad-core GPU System Memory – 2GB LPDDR3 Storage – 16GB eMMC flash, MicroSD card slot up to 32GB Display – 7″ touchscreen IPS display with 1920×1200 resolution Video Output – Micro HDMI port Audio – 3.5mm headphone jack Camera – 5MP front-facing camera (OV5648 sensor) Connectivity – 802.11b/g/n/ac WiFi 5 and Bluetooth 4.0 via Ampak AP6255 module USB – 1x USB 2.0 port, 1x micro USB OTG port Expansion – 20-pin GPIO board […]
Back in March 2018, LG unveiled webOS Open Source Edition optimized for Raspberry Pi 3 board. Last month, the company released a major version with webOS OSE 2.0 adding support for Raspberry Pi 4, dual displays, FOTA support and more. We missed the release at the time but caught up as LG just released a minor update with webOS OSE 2.1 a few days ago that adds a Japanese keyboard, uses journald, and provides various fixes and improvements. Some of the new features of webOS OSE 2.x include: Dual-display support which will eventually enable multi-display support for rear-seat entertainment (RSE) systems Firmware-Over-the Air (FOTA) Smack integration for enhanced security New passenger-friendly and touch input optimized Home Launcher as shown above WiFi tethering support via SoftAP Added support Raspberry Pi 4 (new reference hardware) Upgrade to Qt 5.12 and Chromium 72 webOS is generally known as an operating system for televisions, but the short changelog above makes it clear the company […]
webOS, originally developed by Palm, is a Linux based multitasking operating systems with support for HTML5 and CSS3. It is now found in most (all?) new LG smart TVs, and the TV manufacturer has decided to expand the adoption of webOS by collaborating with the South Korean government and local startups, and released an open source version , webOS Open Source Edition, available publicly at http://webosose.org. webOS Open Source Edition 1.0 is said to be optimized for the Raspberry Pi 3, and the company provides build instructions on the “setting up” page of the website to build the firmware image, which you can then flash to a micro SD card. The idea is to for a community around the open source version webOS, and let different categories of developers or users contribute to the project: System UI Developers – The System UI is based on Blink and Qt, and developers can add new features and integrate other open source technologies […]
Xlab (Maxim Kouprianov) has tested 2D & 3D capabilities of AllWinner A10 SoC (with Mali-400 GPU) on a Ployer MOMO11 Bird Edition tablet running OpenEmbedded with kernel 3.0.52+ testing X11, EGL, OpenGL ES2 and Qt4 on the platform, and the results are pretty smooth as you can see in the video below, although there appears to be some flickering in LunaSysMgr demo. The tools used in the demos are xfwm4 (Xfce Windows Manager), es2gears_x11, cube (Qt), LunaSysMgr (Qt/WebOS) and glmark2-es2. Qt4 acceleration is done via XlibGL platform which in turns uses X11-EGL. He used the Mali drivers version r3p0 (mali400-gles20-gles11-linux-x11-ump) and xf86-video-mali on sunxi-linux github repository mainly maintained by rz2k. You can get more details on how to build Mali-400 support for AllWinner A10 on http://linux-sunxi.org/Mali400, and GPU benchmark results for A10 show the drivers seem to work as expected. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, […]
Open webOS 1.0 is planned to be released in September 2012, but in the meantime, the development team has released an intermediate webOS “Community Edition” for the HP TouchPad. This code is different from the Open webOS project, and is composed of additional components from the current release of webOS for the TouchPad. The open webOS project team has been working with WebOS Internals to bring this release out for legacy TouchPad devices. Thanks to the release of the webOS Community Edition, it is now possible to learn how the TouchPad works, modify your TouchPad experience and then apply that to Open webOS 1.0 once it is released. The Community Edition only supports HP TouchPad, whereas Open webOS 1.0 release will enable the community to port webOS to different hardware platform, and add more features by using open source stacks such as BlueZ bluetooth and GStreamer. You’ll need to download 2 packages to work with WebOS CE: CE-build-support.tgz – A […]
Tim Bird, software engineer at Sony, discusses recent development in embedded Linux at the Embedded Linux Conference 2012. Abstract: Tim discusses changes to the kernel, improvements to embedded-related sub-systems, and new industry initiatives likely to affect embedded Linux developers in the future. Also, Tim discusses the direction of the Linux Foundation CE Workgroup, and their contract work and projects for this year. Last year highlights are also discussed, as well as ways to continue to improve Linux going forward. Here are the key points of this presentation: Linux Kernel Version changes: 2.6.38 to 3.3-rc3 Technology Areas: Bootup Time – With improvement in the kernel, bootloader and user-space Graphics – 2D/3D implementation. New /dev/ion and CMA graphics stuffs Accelerated Rendering – e.g. Renderscript Graphics Drivers – e.g. PowerVR Multimedia – Gstreamer, Android Media Layer (stagefright) and codec wars (e.g. patent issues with WebM/VP8 that interferes open source licenses). File systems – Mainly UBIFS (default raw flash file system replacing JFFS2) and […]
OpenMobile World Wide Inc. is demonstrating its Application Compatibility Layer (ACL) technology, capable of running Android apps on non-Android devices at CES 2012 in Las Vegas. The company claims that their solution brings more than 300,000 Android apps to device running on other platforms. The technology allows OEMs of Tablets, Set Top Boxes, smart TVs, Netbooks, In-Vehicle Infotainment devices and more to provide users access to a all Android applications. OpenWorld ACL technology currently works on tablets, STBs and netbooks based on MeeGo, WebOS and Ubuntu. The company also plans to make the technology available for Tizen, Windows, Bada, QNX, Symbian and more. The company claims 100% compatibility for Android apps including those developed using the Android Native Development Kit (NDK). The ACL layer is said not to drain the device resources at all. Device power and memory will be unchanged. Here are the Key Benefits of ACL according to OpenMobile: ACL destroys the App barrier ACL is 100% compatible […]
