Ubuntu on AllWinner A10 based Mele A1000 Set-top Box

I’ve recently received and reviewed the 70 USD Mele A1000 STB powered by AllWinner A10, but haven’t been able to hack it yet since I’ve have not received the USB to Serial cable necessary for debugging the board. However, somebody else (Tom Cubie) had time to hack the box and run Ubuntu from a SD card (while still keeping Android in the flash) as you can see below. This port does not seem to include hardware accelerated GUI just yet, but this is definitely a step in the right direction. Tom said he just followed the instructions at http://rhombus-tech.net/allwinner_a10/hacking_the_mele_a1000/ and http://rhombus-tech.net/a10_mmc_boot/ to have Ubuntu working, but those do not appear to be that clear at the moment.

Cross-compiling the ARM Linux Kernel in Ubuntu 12.04 LTS

Yesterday I installed Ubuntu 12.04 ‘Precise’ Beta 1 in Virtual Box to give it a try (I could not manage to have HUD working btw), and today, I’ve noticed an article entitled “Ubuntu 12.04 ‘precise’ and cross compilation of ARM kernels” explaining how to build Linaro ARM kernel in Ubuntu 12.04. So I’ve decided to give it a try, especially it seems straightforward. I followed the instructions in the aforementioned link, it basically worked except I had to install dpkg-dev package that also installed the build essentials (gcc, g++, etc…) and use sudo for some commands. You’ll notice the name change for the ARM gcc toolchain as it now uses hard-float by default which seems to provide quite a boost in performance for the Pandaboard. Here are the steps I followed: Install the ARM GCC cross compiler and the development package of dpkg:

sudo apt-get install gcc-arm-linux-gnueabihf dpkg-dev

1	sudo apt-get install gcc-arm-linux-gnueabihf dpkg-dev

Retrieve the kernel source:

apt-get source linux-source-3.2.0

1	apt-get source linux-source-3.2.0

Install […]

How to Install Windows 8 in Linux with QEMU

Microsoft has just released Windows 8 Consumer Preview. Here’s a method to install Windows 8 in Linux using KVM and Qemu. You can use this beta version of Windows 8 until the 15th of January 2013, after which it will be unusable. Here are the requirements to install Windows 8: 1 GHz Processor or greater 1 GB RAM 20 GB free storage for the 64-bit version Before you start, make sure your processor supports Intel Virtualization Technology (VT) or AMD’s AMD V CPU virtualization extensions. Type this command to check vmx or svm flags:

egrep --color "(vmx|svm)" /proc/cpuinfo

1	egrep --color "(vmx\|svm)" /proc/cpuinfo

If this is the case, you can install KVM. Type the following command for RPM-based distributions such as Fedora:

sudo yum install kvm

1	sudo yum install kvm

or the following command for Debian or Ubuntu:

sudo apt-get install qemu-kvm

1	sudo apt-get install qemu-kvm

Then download the ISO image of Windows 8 on Microsoft website (64-bit version) :

wget http://iso.esd.microsoft.com/WCPDL/BD1B8A49393E30CC9C4E5C88457D73E964F1F3B18/Windows8-ConsumerPreview-64bit-English.iso

Ubuntu on ARM: Improvements and Optimizations Done by Linaro – ELCE 2012

Ricardo Salveti de Araujo, developer platform lead for Linaro, displays the improvements Linaro have added to Ubuntu on ARM. Abstract: Since Linaro’s start, there was a need to have a supported platform for ARM, that could use the Linaro changes, to improve the ARM experience in general and to show the results of the work done by Linaro. In this session, it’ll be presented why Ubuntu was selected as the base platform for Linaro, describing the benefits and the areas Linaro is continuously investing to improve it. It’ll also be described the current state of the platform, showing some of Linaro’s achievements and also how we’re working to support the main SoC boards available, like Panda, Beagle, Origen, iMX53 and Snowball with the latest development by Ubuntu and Canonical, like Ubuntu TV, Phone and Tablet.

Low Cost Freescale iMX6 Quad Sabre Lite Development Board

i.MX6q SABRE Lite Board is a low-cost development platform based on Freescale Quad Core Cortex A9 i.MX 6Quad Application Processor. This will probably be the first low cost ARM quad-core development board to hit the market. Nvidia has previously announced the CARMA Tegra 3 CUDA Development Kit, but the price has not been announced and when I look at the picture of the board and the specs, “low cost” does not come to mind. Here are the technical specifications for the Sabre Lite board: Quad-Core ARM® Cortex A9 processor at 1GHz per core 1GB DDR3 @ 532MHz 3 display ports (RGB, LVDS, and HDMI 1.4a) Two camera ports (1xParallel, 1x MIPI CSI-2) Multi-stream-capable HD video engine delivering H.264 1080p60 decode,1080p30 encode and 3-D video playback in HD Triple Play Graphics system consisting of a Quad-shader 3D unit, and a separate 2-D and separate OpenVG Vertex acceleration engine for superior 3D, […]
