Ubuntu Touch Developer Preview Is Now Available for the Galaxy Nexus and Nexus 4, 7 and 10 Devices

As promised with the announcement of Ubuntu on Tablets, Canonical released a developer preview of Ubuntu 12.10 for smartphones and tablets that can be installed in Galaxy Nexus and Nexus 4 smartphones, as well as Nexus 7 and Nexus 10 tablets. It is an experimental development snapshot that could potentially brick your device. Many features are still not available but you should be able to access the following: Shell and core applications Connection to the GSM network (on Galaxy Nexus and Nexus 4) Phone calls and SMS (on Galaxy Nexus and Nexus 4) Networking via Wifi Functional camera (front and back) Device accessible through the Android Developer Bridge tool (adb) You’ll be able to reinstall Android after trying it out, but all your data will be lost, unless you use apps such as Titanium Backup. The instructions to install Ubuntu 12.10 Touch are available on Canonical website, and you’ll basically […]

Canonical Unveils Ubuntu on Tablets

Yesterday, Ubuntu.com displayed a time counter for an announcement reading “Tic Toc Tablet Time” that ended being about Ubuntu on Tablets, and not an HTC Tablet running Ubuntu as some blogs speculated, as both companies had a timer counter set to expire at the same time for separate, and unrelated, announcements. The interface looks very much like Ubuntu for Phones with a similar “Welcome Screen”, except multiple users are supported, no icons (except for apps), and you can swipe around the 4 edges to access the dash, opened applications, notifications, and more. Canonical highlights 5 key features for Ubuntu on Tablets: Real multitasking – Run mobile and tablet apps at the same time on the same screen Secure multi-user Voice controlled HUD productivity Edge magic for cleaner apps – As I said previously no buttons, you control eveything from the edges. Content focus – Messages and media are easily accessible […]

Ubuntu Linaro 12.11 with 2D/3D Mali-400 GPU Acceleration on ODROID-X Development Board

A few days ago, Hardkernel released the first version of Ubuntu 12.11 (Linaro) with Mali-400 GPU support for their ODROID boards (ODROID-X/X2, ODROID-U/U2). This is still WIP (Work in Progress), but this is one of the few boards together with Pandaboard, Origen and Snowball that can support 2D/3D GPU acceleration in Ubuntu Quantal. Since I have an ODROID-X development board, I decided to give it a try. There are different ways to install it. I chose the way that is most convenient for me (LCD display instead of HDMI), and likely to yield more performance (eMMC instead of SD Card). The current installation instructions to eMMC are extremely cumbersome and you have to go through 5 main steps: Install Android (yes, seriously) in the eMMC Install Ubuntu in the SD Card Install Ubuntu to the eMMC Upgrade Ubuntu to the latest version Install the Mali drivers In this post I’m […]

ARM big.LITTLE Processing Demo (HMP) on ARM TC2 Test Chip

Samsung launched Exynos 5 Octa at CES 2013. This processor comes with 8 cores: 4 Cortex A15 cores and 4 Cortex A7 cores, and it’s the first processor that’s been announced to work in big.LITTLE configuration, where the big cores (A15) handle demanding tasks, and the LITTLE cores (A7) handle simpler tasks such as audio playback or background tasks. This is all done to optimize power consumption. There are 2 big.LITTLE software implementations: In-kernel switcher (IKS) and heterogeneous multi-processing (HMP). The first one is easier to implements but can only use 4 cores (in Exynos 5 Octa) at a time, and the second is more complex, but can handle all 8 cores, and assign individual tasks to a particular core. For more technical details about big.LITTLE implementations, you can read my previous post. ARM and Samsung recently uploaded a video providing an overview of big.LITTLE (but instead of IKS and […]

Open ARM GPU Drivers FOSDEM 2013 Video and Call to ARM Management

As I previously wrote, FOSDEM organizers are slowly uploading FOSDEM 2013 videos. One of the most interesting talk “Open ARM GPU Drivers” is now available. I’ve also uploaded it to YouTube (embedded below) to give it more exposure. Luc Verhaegen has also written a recent blog post entitled “Hey ARM!” where he announces the release of the modified source for Quake 3 Arena demo, and asks ARM to join them in making an open source driver. Open ARM GPU Drivers @ FOSDEM2013 This session covers the following key points: Problem – Binary drivers are mainly designed to run in Android, and it’s very difficult to have proper GPU drivers for Linux, and companies are not interested to release open source drivers or even just documentation, as they are not convinced it will benefit them in any way. Legal – This is actually the main issue, as open sourcing existing driver […]

ARMBRIX Zero Cortex A15 Development Board Unboxing Pictures

I’ve just received an early sample of ARMBRIX Zero (aka ARMBRIX-5250-A), a development board based on Samsung Exynos 5250 dual cortex A15 processor with 2GB RAM, a microSD slot, 1x USB 3.0, 2x USB 2.0 Host, 1x USB Device, 10/100 Ethernet, HDMI output, SATA 3.0, some Audio I/O ports, and 3 expansions headers. This is basically a low cost version of the Arndale board, with things such as eMMC 4.5 (Sorry I’ve missed the eMMC socket at the back of the board) sensors missing. Today, I won’t turn the board on (I’ll explain why at the end of the post), but instead show some pictures of the development and debug boards. If you had previously seen the board picture before, you’ll noticed it has a grown a heatsink. The heatsink is probably here to stay, but may be slightly different (e.g. lower) when you receive your board. The bottom acrylic […]

Linaro 13.01 Release with Linux Kernel 3.8 and Android 4.2.1

Linaro has just announced release 13.01 which includes Linux Kernel 3.8-rc4 and Android 4.2.1. A lot of work seems to have gone in Arndale board and OpenEmbedded ARMv8. It’s the first time an Ubuntu image is released for Arndale Cortex A15 development board. One the kernel side some Android upstreaming work has been done, as well as some fixes for eMMC, and code for ST Ericsson Novathor 8500 SoC has been reorganized. Version 14 of the big.LITTLE MP (Multi Processing) has been released. The LEG has done further work on Linaro UEFI and GRUB. Here are the highlights of this release: Android Platform Work The first step of the android-build front-end update for new build program has been landed. Origen and Versatile Express manifests have been consolidated into a single manifest. linaro-android-tools were developed to improve development time for kernel developers. See Kernel Update Tools for details. The android-build scripts […]
