Android Jelly Bean on Samsung Origen Development Board (Video)

Linaro Android team has started to port Android Jelly Bean to Samsung Origen board (powered by Exynos 4 dual core processor) and can now show Android 4.1 running on the board with hardware accelerated graphics. This is a preliminary image: the touchscreen, graphics, adb works, and you can use keyboard and mouse as input devices, but Wi-Fi, Bluetooth and multimedia (hardware video decoding) still have to be worked on. If you have an Origen board, you can give it a try by downloading the binaries @ https://android-build.linaro.org/builds/~linaro-android/origen-jb-gcc47-samsunglt-stable-blob/, and follow the instructions to create a bootable SD card with linaro-media-create.

Smallart U-Host mini PC Unboxing and Review

I’ve just received a Smallart Uhost mini PC based on AllWinner A10 from the “The Cubies hacker shop” on Aliexpress.

Linaro 12.07 Release with Kernel 3.5 and Android 4.0.4

Linaro has released version 12.07 based on Linux Kernel 3.5-rc3 and Android 4.0.4. Some work has been done on Jelly Bean (but the port is for next month), several benchmark tools have been added to LAVA as Linaro wants to provide standard benchmarks for Android, Linaro ALIP image now uses LXDE by default with a smaller image and improved performance, and Open Embedded images are now available (minimal and LAMP stack). Here are the highlights of the release: Android Jellybean baselines for Galaxy and Panda with Linaro extra’s available Android Benchmarking apps were deployed for pandaboard, snowball and origen in LAVA including: vellamo, quadrant, nbench, linpack, glbenchmark, geekbench, caffeinemark, antutu, andebench Improved native Benchmarks variance on Android to 1%, working on Java variance ICS “tests” builds now produced by default and test lists generated Open overlay tarballs working pm-qa’s cpuidle cpufreq cpuhotplug sched_mc suspend integrated into the Android builds Linaro Android Snowball 4.0.4 is now in par with Snowball 4.0.3 …

VIA Releases Kernel 2.6.32 and U-Boot Source Code for $49 APC Board

VIA Technology unveiled the low cost APC (Android PC) board based on WonderMedia WM8750 processor (ARM11) back in May, and started to ship the Android board this month (I think since that was their plan). The company has just released Kernel 2.6.32.9 and U-Boot source on github. Here’s how to retrieve the code provided git is already installed on your machine: You can then build U-Boot (provided you’ve already installed an ARM toolchain in your path): and the Linux kernel: The availability of the source means we should see Linux distribution like Debian, Fedora or Arch Linux ARM (separate from Arch Linux) running on the board very soon. In theory, it’s also possible to run a Linux distribution with the binary Linux kernel compiled for Android, but it causes some issues and also makes customization more difficult. I think they should also have release the code they modified for Android, but apparently did not. The next step would probably be to …

LinuxCon North America 2012 Schedule

LinuxCon (North America) 2012 will take place on August 29 – 31, 2012 at Sheraton Hotel & Marina, in San Diego, California. The event will be co-located with the Linux Kernel Summit, the Linux Plumbers Conference, and CloudOpen 2012. LinuxCon consists of 3 days of keynotes, business and developers related sessions as well as tutorials. There will be over 80 sessions and keynotes during those 3 days. I’ll highlight a few sessions that I find particularly interesting and related to embedded Linux, software development and ARM. August 29 10:45 – 11:30 – Life After BerkeleyDB: OpenLDAP’s Memory-Mapped Database by Howard Chu, Symas Abstract: OpenLDAP’s new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy’s. Writes are on average twenty times faster than commonly available databases such as …

Discounted and Free Development Kits by Future Electronics and Texas Instruments

If you have a project in mind, Future Electronics and Texas Instruments are currently offering free development boards and 50% discounts on selected development kits respectively. Future Electronics Boards4Free Initiative In August, Future Electronics will be giving away 5 boards every Wednesday (20 boards in total). Here’s how it works: Every Wednesday at 12 pm EST from August 1 to August 22 Future Electronics will post a board on their  Twitter, Facebook and Google+ feeds.

How to Get Free Hotel Rooms with An Arduino Board and a Resistor

Earlier this week, Cody Brocious (Daeken) gave a presentation at the Black Hat conference in Las Vegas showing how it was possible to hack and open hotel door locks (Onity HT lock systems), using an Arduino Mega 128 board, a 5.6 kOhm resistor and a DC barrel plug to physically mate with the lock (Total price: around $20). He explains that 4 million hotel rooms are fitted with this type of lock, which means you could potentially stay for free anywhere in the world. Obviously, you could also end-up in another type of room (including free food) for a longer period of time. That looks like a win-win situation to me 🙂 Each locks contain a 32-bit unique value (sitecode) that identifies a property, and is used for encryption. Cody’s Arduino’s based solution can communicate with the lock over a 1-wire communication protocol read memory to get the sitecode (no authentication required) and open the lock. Opening the door usually …

16 Euros Arduino Leonardo Board is Now Available

Arduino Leonardo is a new Arduino board with a 16 MHz Atmega32U4, 2.5KB RAM, 32 KB of Flash memory, 20 digital I/O, 12 analog inputs and 7 PWM outputs. In this version the MCU takes care of USB communication with the host, whereas for Arduino Uno, a separate chip is required to take care of this, which makes Arduino Leonardo cheaper than Uno. Here’s a summary of Arduino Leonardo specifications: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 channels DC Current per I/O Pin – 40 mA DC Current for 3.3V Pin – 50 mA Watch the video to get an introduction to this new Arduino board, and see how …
