Linaro 14.04 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.04 has been released with Linux Kernel 3.14 (baseline), Linux Kernel 3.10.37 (LSK), and Android 4.4.2. More work has been done on ARMv8 support, and big.LITTLE for both the Linux kernel and Android, as well as work on member hardware platforms such as Origen, Arndale, Arndale Octa, Broadcom Capri, and Hisilicon D01 boards. GCC 4.8-2014.04 Linaro is said to include performance improvements. Linaro Android engineering builds for Nexus 7 and Nexus 10 have been setup, but I can’t quite find the images. They’ve also added the BeagleBone Black to member builds. Here are the highlights of this release: Linaro Stable Kernel (LSK) 3.10.37-2014.04 Updates to Android support (from Google and Linaro) Added Big endian for ARMv7 and ARMv8 Thermal framework DT support Huge pages and transparent huge pages for ARMv8 Tagged pointers for ARMv8 Non-coherent DMA for ARMv8 Other Features big.LITTLE support – ARM MP patch set, IKS (ARMv7 […]

Embedded Linux Conference 2014 Schedule

The Tenth Embedded Linux Conference (ELC 2014) will take place on April 29 – May 1, 2014 at the San Jose Marriott in San Jose, California. The event will feature 90+ sessions on embedded Linux, Android and IoT with over 450 attendees expected to attend. It will also be co-located with Android Builders Summit and the AllSeen Alliance Hackfest. Even if you can’t attend it’s still interesting to see what will be discussed at the event to get a grasp of on-going developments, learn a few things about different optimization techniques, and so on. So I’ve gone through the sessions’ description, and I’ve designed my own virtual schedule with sessions that could be of interest. April 29 9:00 – 9:30 – Keynote: The Paradox of embedded and Open Source by Tim Bird, Sony Mobile Linux has taken the embedded world by storm.  Billions (with a ‘B’) of devices have now shipped […]

There’s also a Linux image (password protected) for Huawei D01 board with a 16-core ARM Cortex A15 @ 1.5 GHz SoC with up to 64 GB memory, that must be an unannounced SoC for base stations or other network equipment.  This month Linaro also made two important announcements: Qualcomm is now a Linaro member, and the Linaro Security Working Group (SWG) has been setup to develop open source secure software for the ARM architecture. The first projects will be reference implementations of the W3C Embedded Media Extension (EME), and secure boot for the 64-bit ARM Cortex-A series processors. They’ll also work on security […]

Linaro 13.10 Release with Linux Kernel 3.12 and Android 4.3

Linaro has just posted a blog entry to announced Linaro 13.10 was available for download. This is normally supposed to occur on the last Thursday of the month, but it’s possible the release occurred on scheduled, and the blog post was late, or it may have been delayed because of Linaro Connect US 2013.

Some new hardware platforms I may have missed before have popped up […]

Tizen 3.0 Features & Tizen Lite Unveiled

We have just learned about NX300M camera, the first Tizen device, based on Tizen 1.0, but development of the new mobile operating systems is still going on, and the key features of Tizen 3.0, as well as Tizen Lite, Tizen for low-end hardware, have been unveiled at the Tizen Developer Summit on 11th of November 2013. Tizen 3.0 features: Update core OS and toolchain Multiple user support 64-bit Intel and ARM architecture support (New) 3D UI Framework with 3D rendering for 2D and 3D objects in 3D, and a dynamic animation library WayLand based compositor replacing X Crosswalk – HTML5 based application runtime based on Chromium/Blink Tizen 3.0 release is scheduled for Q3 2014, so the first Tizen smartphones and tablets which are expected for Q1 2014 will probably ship with Tizen 2.2.1, or even possibly with an earlier version. Android KitKat 4.4 has been optimized to run smoothly on […]
