Phoronix Designed a Solar Powered ARM Cluster with 48 Pandaboards

Michael Larabel of Phoronix did a “little” week-end project at the Massachusetts Institute of Technology (MIT), building an ARM cluster with 48 Pandaboards mostly with standard Pandaboards (OMAP 4430), although some Pandaboard ES (OMAP 4460) were also thrown in the mix. The 96-core cluster consumes just over 200 Watts under load and can be powered by a solar panel. The boards are stacked up vertically in an industrial trashcan, and are powered via USB instead of AC adapters. Michael’s PandaBoard ES testing indicates about a 3 Watt idle per board, 5 Watt under load, or 6 Watts under extreme load. The cluster idle power consumption is just under 170 Watts while idle, and goes slightly over 200 Watts under load. Each Pandaboard runs Ubuntu 12.04 ARM OMAP4 installed on SD cards. MIT did some testing and provided Phoronix with benchmark results such as tests following Green500 benchmarking procedure, but they are […]

Freescale Announces Availability of Kinetis L Series Cortex M0+ MCU and Freedom Devkit

ARM unveiled its ultra-low power Cortex-M0+ core back in March, and Freescale and NXP also announced their plans to use this new core in some of their micro-controllers destined to power the internet of things. Yesterday at Freescale Technology Forum (FTF), Freescale announced the availability of alpha samples of its Kinetis L series. This new low power MCU family will allow existing 8-bit and 16-bit architecture to be replaced by 32-bit architecture without increasing power consumption, cost or size, and the company expects them to be used in devices such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control. The ARM Cortex-M0+ processor is said to consume about a third of the energy of any 8- or 16-bit processor, while delivering between two to 40 times more performance. Kinetis L series MCU can consume as low as 50 uA/MHz in very-low-power run (VLPR) […]

Mele A1000/A2000 Android 4.0 Image Released

At last, a (semi-)official Android 4.0 release (and not a beta) for Mele A1000 and Mele A2000 media players has been released. This release is based on AllWinner Android 4.0 SDK. You can download homlet_4.0_v1.0_20120609_dd.img.lzma or here and dump it to the SD card with dd (Linux) and Win32DiskImager (Windows). It is also available via Bittorrent. There is also another image named homlet_4.0_v1.0_20120609.img.lzma that can be flashed via the Phoenix Utility, but the download link is not available anymore at the moment. Here are the instructions in Linux:

wget http://www.lundman.net/ftp/mele/homlet_4.0_v1.0_20120609_dd.img.lzma
7z x homlet_4.0_v1.0_20120609_dd.img.lzma
sudo dd if=homlet_4.0_v1.0_20120609_dd.img of=/dev/sdX bs=1M
sync

wget http://www.lundman.net/ftp/mele/homlet_4.0_v1.0_20120609_dd.img.lzma

7z x homlet_4.0_v1.0_20120609_dd.img.lzma

sudo dd if=homlet_4.0_v1.0_20120609_dd.img of=/dev/sdX bs=1M

sync

Where you need to replace X in /dev/sdX by the correct letter for your SD card reader. Now insert the SD card in your Mele, and wait until the LED stops blinking, remove the SD card and restart the device. Et voila! The default language is Chinese, so you’ll have to go to the Settings to change the language to your […]

Getting Started with Emcraft Systems Cortex M3/M4 Starter Kits Running uCLinux

A few months ago, I wrote a post about running uCLinux on Cortex M3/M4. Since then I’ve had the opportunity to play a with Cortex M3 & M4 boards capable of running Linux, as last week, I received Emcraft Systems Freescale K70 Starter Kit together with their MicroSemi (previously known as Actel) Smartfusion SoM. Today, I’ll show some pictures of the baseboard and modules I received in the kit, and some details about the documentation and how to get started with the modules. Unboxing Pictures Here’s the baseboard with Ethernet, USB interface using USB-UART bridge connected to the UART0, JTAG connectors (P3 and P5), two push-buttons and a breadboard for easy access to unused signals (ADC, I2C, SPI, UART and GPIOs). P4 and P6 are the sockets to plug in the SoM. There is a lithium-ion battery (CR2016) at the back of the board for the RTC clock. As previously […]

MK802 Android 4.0 mini PC Factory Video

Nicolas Charbonnier, better known as charbax, has shot yet another cool video in one of the small factories where MK802 is assembled, showing the different steps they follow to build a complete device. The PCB assembly is probably done in another factory, and they just assemble the device in this factory, or I should probably call it a workshop… The place appears to be rather small and everything is done by hand, but that’s what makes the video very interesting. This is the company that sells it on Amazon under the brand “OEM Systems Company”. The first five minutes shows a tour of the factory, and in the rest of the video, Charbax interviews the sales manager and the owner of the factory who both dodge sensitive questions about pricing, BOM costs and quantities manufactured monthly… But hey, you’ve got to try.

GeneralPlus GP3300X Application Processor Details

Earlier this week, I wrote about GeneralPlus GP3300 Cortex A8 processor and its tablet development platform, but I did not have that much details about the processor itself. I eventually managed to get a bit more information today. GeneralPlus GP33000 family features 2 processors: GP33003 which comes in LQFP216 package and supports up to 512 MB DDR3 RAM. GP33009 which comes in BGA328 package, supports up to 1GB DDR3 RAM and more interfaces such as SPDIF, Ethernet, IR interface and CF card support. GP33003 appears to be better suited for tablets whereas GP33009 could be used in set-top boxes and digital signage players with Ethernet, IR remote and CF card support. The capabilities of these processors are better represented in the block diagram below. This processor features a Cortex A8 core with 32KB L1 cache and 256KB L2 cache, a 2D/3D engine (PowerVR SGX531 GPU), a video decoder and a […]
