March 29th, 2013 No comments

Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2.

This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available.

Here are the highlights of this release:

$135 ARMBRIX Exynos 5 Dual Cortex A15 Development Board

December 16th, 2012 13 comments

If you want to develop on a Cortex A15 processor, but Arndale development board is a bit expensive for you, don’t despair as ARMBRIX development board featuring Samsung Exynos 5 Dual processor is currently being developed and should be available in Q1 2013 for $135.

ARMBRIX Development Board Layout

The preliminary specifications include:

  • SoC – Samsung Exynos 5 Dual Cortex A15 CPU + Mali T604 GPU
  • System Memory – 2 GB DDR3 @ 800 MHz
  • Storage – microSD slot
  • Video Output – HDMI
  • Audio In/Out – HDMI, SPDIF, Line In/Out.
  • USB – 2x USB 2.0 Host, 1x USB 3.0 host and 1x USB 2.0 device
  • Ethernet – Via USB to Ethernet hub.
  • SATA – The connector is on the left of the micro SD slot.
  • Expansions – 3 headers.
  • Dimensions – 85 x 95 mm

This board is based on Arndale design, and will be software compatible. Currently, Arndale officially support Android only, but some instructions to setup the board as with Ubuntu server and boot from the network are available on Linaro website. Ubuntu can run on Google ARM Chromebook, which is based on Exynso 5 Dual, so there should be no problem running it on this board, although I’m not sure about GPU support.

That’s all the details I have for now. I would have wished they added a SATA connector, since Exynos 5 Dual processor embeds a SATA 3.0 controller, and it might not have added much to the cost. There is already a SATA connector.

ARMBRIX website will officially be launched end of December, beginning of January, and you’ll be able to pre-order the board for $135. The website is still under construction, but you may already notice some links to InSignal, the company behind Origen and Arndale boards. It appears they did not designed the ARMBRIX board, but were contracted for software development and support. I’ll most probably review the board once it becomes available.
