Getting Ubuntu armel/armhf Rootfs in Ubuntu 12.04

I’ve recently upgraded to Ubuntu 12.04 and this is a great operating system. However, if you do some arm development and expect to be able to install cross libraries (armel/armhf) or easily generate an arm rootfs using the tools you’ve been used to, you’ll be disappointed. In Ubuntu 11.10 (Oneiric), I used xapt and dpkg-cross to retrieve armel libraries, but it’s broken for Ubuntu 12.04, at least on my system. I’ve been told to switch to multiarch because this will be how it’s done from now on. But I soon discovered this is work in progress as quite a few packages are not multiarched yet including python. Ubuntu developers also decided to remove rootstock (which makes sense since xapt/dpkg-cross will be deprecated), so if you want to generate a rootfs the “gool ol’” way (which won’t be supported much longer), you’d have to install an Oneric chroot to run rootstock, or copy the rootstock script in Pangolin. There are 2 …

74 USD AllWinner A10 Android 4.0 Mini PC

A cheap white brand Android 4.0 USB/HDMI Stick based on AllWinner A10 has started to show up in Chinese websites. Initially, I thought it was like a low cost version of FXI Tech Cotton Candy (which will start shipping this month), but as you can see in the image below, the HDMI port is female so you’d still need a HDMI cable. The hole next to the USB port should be for the power supply, so this device is apparently not powered via USB (TBC). Connect a wireless mouse and keyboard to the device, the power supply, and an HDMI cable to your TV, and you’ve got yourself a cheap PC running Android 4.0. Since this is based on AllWinner A10, you could also insert a microSD card with Ubuntu, Debian or your other favorite Linux distribution and have yourself a Linux PC. Here are the specifications of the device (gathered on the internet so it’s not error prone). CPU …

Energy Micro EFM32 Tiny Gecko (Cortex-M3) Starter Kit Unboxing

I’ve been lucky recently, after winning a TI Piccolo controlStick last month, I’ve just received Energy Micro EFM32 Starter Kit (EFM32-TG-STK3300) based on EFM32 Tiny Gecko MCU. This development board include: EFM32 Tiny Gecko Cortex-M3 MCU 8×20 LCD A light sensor A touch slider A battery compartment SEGGER J-Link mini USB port 2 Button + 1 reset button 1 User LEDs 2 expansion ports. Lots of through holes to access the different pins of the MCU Today, I’ll just show the content of the kit and next time, I’ll post more about the things I’ve done with it. Here’s the package of the EFM32 Starter Kit. The 2 gecko eggs were not included… Actually, those are house geckos eggs which are smaller than real geckos. We’ve got those here as well, but there are very shy, whereas house geckos just run around the walls and ceilings all day. Well, it’s like Energy Micro released the Gecko board back to its …

Intel Roadmap to 2015 and Beyond: 5nm Technology, Merrifield Mobile Processor, Microservers and More

Intel had their annual Investor meeting day on the 10th of May 2012 in Santa Clara where we would learn a few things about what’s ahead for Intel and the semiconductor industry. Paul Otellini, Intel President and Chief Executive Officer, started the meeting by  giving some numbers about Intel results and showing opportunities existing for cloud and data center, personal computing, mobile devices and intelligent systems (for automotive, retail and communications markets). One interesting point was the tremendous growth in data Intel expects from 2,500 Exabytes per year (7 EB/day) today to 8,000 Exabytes by 2015 which the majority of the growth lead by Big data. He also boasted about Intel technology advantage. For example, Intel introduced High-K Metal Gate technology in 2007 and competitor only got it in products last year (btw Samsung Exynos 5 uses HKMG). They recently introduced Tri-gate technology and they only expect competitors to catch up within 4 years. Finally one of the slide (see …
