Linaro 14.05 has been released with Linux Kernel 3.15-rc5 (baseline), Linux Kernel 3.10.40 (LSK), Android 4.4.2, and Ubuntu has been switched from Saucy to Trusty. More work has been done on big.LITTLE processing and ARMv8 support with notably completing bootstrapping with Debian 64-bit. New hardware platform have started to pop-up such as TI J6-Vayu which must be an evaluation board for Texas Instruments Jacinto 6 dual core Cortex A15 SoC for automotive application, as well as IFC6410, a Snapdragon 600 development board which got a Ubuntu LEB image. This month also marks the first release of Linaro GCC 4.9 toolchain. Here are the highlights of this release: Linux Linaro 3.15-rc5-2014.05 new Android topic (linaro-android-3.15-experimental) uses the resent AOSP code base GATOR version 5.18 (same version as in 2014.04) uprobes topic removed as all patches have been accepted into mainline updated big-LITTLE-pmu topic from ARM LT updated basic Capri board support […]

Linux Kernel 3.10.33 Source Code Released for Amlogic S802 (Part of Tronsmart Vega S89 SDK)

We already had the kernel source for Amlogic S802. The previous code found on Amlogic website, and based on Linux 3.10.10. I’ve been informed there’s a new release based on Linux 3.10.33, and apparently the code based used for Tronsmart Vega S89 (aka Beelink M8, S82), and the new Tronsmart Vega S89-H with proper Dolby & DTS support. Beside a new version, the kernel adds support for a new platform called “meson8 baby” and HDMI IN support, as well a several changes in AMlogic source such as GPU cooling.. All device tree files also seem to have been amended mostly with I2C and thermal settings. It is not a full release, and the hardware directory with GPU, TVIN, Wi-Fi, and NAND drivers is not included. Having said that, it should be possible to use the drivers from the previous release. Meson6 (Amlogic AML8726-MX) source code is also included, and appears […]

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 […]

Atmel SAMA5D3 Xplained Board Unboxing and Quick Start Guide

Atmel SAMA5D3 Xplained is an evaluation board running Linux powered by SAMA5D36 ARM Cortex A5 micro-processor with 256 MB DDR2, 256 MB flash, two Ethernet ports, 3 USB connectors, and more. This embedded board targets industrial automation, networks, robotics, control panels and wearable applications. The only video output is an LCD connector so it is reserved for headless or flat panel based applications. You can check full specs on my Atmel SAMA5D3 Xplained announcement post. The company kindly sent me a sample, so that I can share my experience with the board. I’ll first post some unboxing pictures, show how to get started with the pre-installed image, and build my own Linux image. The board can be purchased for $79 from Atmel e-Store, as well as several distributors (P/N: ATSAMA5D3-XPLD). Atmel SAMA5D3 Xplained Unboxing I’ve been sent the board via DHL in the following package, which gives a short desscription […]

Linux Kernel 3.14 Release

Linus Torvalds announced the release of Linux Kernel 3.14 yesterday: So we had a few fairly late changes that I could have done without, but the changelog from -rc8 is still pretty small, and I’m feeling pretty good about it all. If we did end up with any last-minute problems due to the final spurt of patches, they’ll be pretty specific, and it really didn’t make sense to me to delay the release without anything known pending. Much of the final spurt were either marked for stable or known regressions. So 3.14 is out there, and the merge window for 3.15 is thus open. Please do spend the time to test out 3.14, though, even if you might otherwise be in a hurry to send me your pending queue for the next release. Linus Kernel 3.13 brought a scalable block layer for high-performance SSDs, nftables, NFC payment support, squashfs performance […]

Mediatek MT6589 Linux Source Code, CyanogenMod 11 Image for Wiko Stairway Smartphone

Mediatek and their customers have still not gotten into the habit of complying with the GPL license, and releasing the relevant source code such as the Linux kernel. There appears to be at least one smartphone, Wiko Stairway, where the Linux kernel has been released, and chrmhoffmann, a members of XDA developers forums, has even released on unofficial CyanogenMod 11 ROM (Android 4.4.2 Kit Kat) for the device. There are three source repositories for the Linux kernel, “android device“, and Android. I’ve only looked into the kernel which is version 3.4.5. Mediatek has apparently messed up the Linux kernel quite a bit, and you’ll have to do some funny things to build the kernel, and all Mediatek options in menuconfig are in a sub-section called “Mediatek Properitary Configuration” (sic.), and it’s not possible to simply go to System Type menu to change the processor type for instance. Let’s get the […]
