$99 (and up) Compulab Utilite ARM based Computer Runs Ubuntu or Android

If you’re ready to tinker it’s possible to run Linux in one of the low cost ARM based set-top boxes or mini PCs currently available, although if you need Linux with 3D acceleration and video playback, your only realistic option is to go with solutions based on Freescale i.MX6. Compulab has been developing a mini desktop computer based on Freescale i.MX6 Solo, Dual or Quad that will run either Ubuntu or Android, so you don’t need to mess around to run Ubuntu on cheap ARM hardware. The device is expected to sell for $99 and up starting in August according to Fanlesstech. Compulab Utilite will have the following specifications: SoC – Freescale i.MX6 single / dual / quad core Cortex-A9 up to 1.2GHz, with Vivante GPU, and Video Processing Unit supporting multi-stream 1080p H.264, VC1, RV10, DivX HW decoding System Memory – Up to 4GB DDR3-1066 Storage – 1MB SPI […]

Play HEVC/H.265 Videos and Embed HEVC Streams into MP4 and TS Files with openHEVC and GPAC

I wrote an introduction to H.265 (aka HEVC) at the end of last year, including instructions showing how to encode videos to HEVC using the reference implementation. It worked but since it was not optimized for speed, it was extremely slow. Today I’ve stumbled across openHEVC, a open source compliant HEVC video decoder written in C, created as a fork of Libav. This is supposed to work pretty well as the implementation was used at Roland Garros Tennis tournament to playback an 720p50 HEVC stream transmitted over DVB-T2, IPTV, and MPEG DASH. Today I’ll mainly tried out the instructions provided on openHEVC github repo including: Build the source and playing a raw HEVC stream with hevc utility Build GPAC (open source multimedia framework), to get MP4Box, mp42ts, and MP4Client utilities. Import a raw HEVC stream into MP4 and TS containers, and play it back with GPAC tools. I’ve performed the […]

Linaro Connect Europe 2013 Sessions and Mini-Summit

Linaro Connect Europe 2013 (LCE13) is taking place in Dublin, Ireland on July 8 – 12, 2013. If you are not there, you can still follow the event remotely as the event schedule is available with tracks focused on Android, Builds and Baselines, Enterprise, Graphics and Multimedia, Linux Kernel, Network, Project Management Tools and Training, and the Testing and Validation mini-summit will also take place at the same time. There will be hacking and lab sessions each day (except on Friday) where you can expect to learn useful skills. I’ve selected 2 sessions per day that I think might be particularly interesting. Monday 10:00 – 10:45 – ARMv8 Status and Updates Current Status of v8 tree What’s merged? What’s features are next priorities? Platform Updates What members should know about adding new v8 platforms 12:00 – 13:00 – How to make Android more efficient for entry level products The main objective of […]

12MB Minimal Image for Raspberry Pi using the Yocto Project

Last year, I wrote instructions and provided a download link about a minimal image for Raspberry Pi based on Raspbian. The compressed image is 84MB, and the good thing about it is that you can just use apt-get to install packages. The problem is that it’s not actually that small as once it is uncompressed the rootfs is still a massive 414 MB. So today, I’ll explain how to create a smaller (and custom) image using the Yocto Project, a platform that let you build an embedded Linux distribution matching exactly your project’s requirements. Other advantages are that the build is configurable with config files, so it’s easily reproducible with a few command lines, and it might turn out to be useful to learn more about the Yocto Project as many boards and SoC are now making use of the framework, including Freescale i.MX6 (Wandboard, Olinuxino-imx233, Sabrelite, etc…), the Beagleboard, […]

$99 Parallella Supercomputer is Now Open Source Hardware

Parallella is a low cost supercomputer designed by Adapteva using Xilinx Zynq-7010/7020 FPGA+2x Cortex A9 SoC combined with Adapteva Ephipany 16 or 64 cores epiphany coprocessor. The project had a successful kickstarter campaign which allowed then to provide the 16-core version for $99, and the 64-core version for $750. The board will soon be shipped to people who pledged on kickstarter, and one of the promise of the campaign was to fully open source the platform, and today, they just fulfilled that. Before going into the details of the open source release, let’s have a look at the specs: SoC – Xilinx Zynq7000 Series (Z-7010 or Z-7020) Dual-Core ARM Cortex A9 with 512KB L2 Shared Cache Coprocessor – Epiphany Multicore Coprocessor. The Parallella-16 board includes the 16-core Epiphany-III processor The Parallella-64 board includes the 64-core Epiphany-IV processor System Memory – 1024MB DDR3L Boot Flash – 128 Mb QSPI Flash Indicators […]

Snowball Board Phased Out, and Offered at a Discount

Snowball is a mobile development board based on ST Ericsson Nova A9500 dual core ARM Cortex A9 SoC , which was officially supported by Linaro (they still released Android and Ubuntu images), and designed by Calao Systems, but since ST-Ericsson venture fell apart, support for the board has been discontinued, and the developer’s community (igloocommunity) has recently been closed down. The last message of the mailing list (now not accessible) reads as follows: A small team of passionate ST-Ericsson people have dreamed about Snowball and they makes it possible. Since December 2011 after a management change, it has been difficult to maintain the program, but with your support, we succeed until this time. Nevertheless, you have been able to demonstrate the pertinence of this program, and its great potential with impressive realizations. In December 2012, STMicroelectronics announced a new strategic plan, where STM takes the decision to exit ST-Ericsson. Then […]

Linaro 13.06 Release With Linux Kernel 3.10 and Android 4.2.2

Linaro 13.06 has been released with Linux Kernel 3.10-rc6 and Android 4.2.2. Linux Linaro Stable (LSK) preview is based on kernel 3.9.6. There seems to have been a lot of activity for the LAVA and Builds and Integration teams, with LAVA support for new SoC such as Huawei K3V2 and Broadcom Capri from 2 companies which have recently joined Linaro as members, and well as continuous build for Linaro Stable Kernel. On the kernel side, more work has been done for multi-platform support (unified kernel), uprobes, eMMC power mamangement, and more. Here are the highlights of this release: LAVA LAVA Core As part of the effort to improve the developer experience with LAVA, the different client tools were consolidated into a single package, which simplifies the process of updating the tools and makes it easier for the team to provide new features for LAVA users. LAVA now supports KVM devices, […]

Ubuntu 12.04 Now Boots on Rockchip RK3188 mini PCs (T428, MK908, Rikomagic MK802 IV…)

After the release of the RK3188 Linux kernel source code last week, Ian Morrison (Linuxium) has managed to boot Ubuntu 12.04 with XFCE desktop on Tronsmart T428. However, as Tronsmart refused to release their source code, further Linux development is likely to happen on Rikomagic MK802 IV, because Rikomagic released the code for their device, so development work will be easier. AFAIK, this is the first time Linux boots natively on RK3188 devices, so it’s still early stage (no Wi-Fi, Bt or graphics acceleration), but if you still want to give it a try here are the instructions (for T428):] Create a SDCARD with an Ubuntu 12.04 root file system on it and ensure it is labeled as “linuxroot” (Visit Slatedroid for details) Flash your RK3188 minipc with rooted stock 4.1.1 ROM. (May not be needed if you ROM is already rooted) Boot Android, and install Android Terminal Flash t428-3.0.36-linuxium-test+-kernel.img […]
