ARM Announces ARM Cortex-M0+ Core to Power the Internet of Things

ARM has just unveiled the ARM Cortex-M0+ 32-bit processor optimized to deliver ultra low-power and low-cost MCUs to power the ‘Internet of Things‘ by controlling connected intelligent sensors and smart control systems in a broad range of applications including home appliances, white goods, medical monitoring, metering, lighting and power and motor control devices. ARM claims the Cortex-M0+ consumes just 9µA/MHz on a low-cost 90nm LP process, around one third of the energy of any 8- or 16-bit processor available today, while delivering significantly higher performance (1.77 CoreMark/MHz). Beside the low power consumption, the main advantage of the Cortex-Mo+ over 8-bit and 16-bit MCUs , is that it can provide low power wireless connectivity to a variety of embedded systems such as wireless sensors. The new processor is based on Cortex-M0 processor but has been redesigned to include a few new features such as: Single-cycle IO to speed access to GPIO and peripherals Improved debug and trace capability 2-stage pipeline to …

Bump In Host on Android – IPv4 to IPv6 Translation – Android Builder Summit

Yonghui Wang, representative of China Mobile to the Linux Foundation, gives a presentation about BIH (Bump in the Host) protocol at the Android Builder Summit in February 2012. Abstract: BIH or Bump-in-the-host realizes a host-based IPv4 to IPv6 protocol translation mechanism that allows a class of IPv4-only applications that work through NATs to communicate with IPv6-only peers on Android. The host on which applications are running may be connected to IPv6-only or dual-stack access networks. BIH hides IPv6 and makes the IPv4-only applications think they are talking with IPv4 peers by local synthesis of IPv4 addresses. China Mobile has released an open source implementation of the protocol. The presentation slides has not available for this talk.

Marvell Releases Kinoma Play for Android and Kinoma Create SDK

Marvell has just announced the availability of the preview release of Kinoma Play for Android which includes a suite of 50 apps enabling digital media, social networking, location, and search.

Command Line Methods to Completly Delete a Hard Drive in Linux

Here are 2 methods to completly dlete the content of an hard drive with dd and shred commands. With those methods you won’t be able to recover the data. This can be useful in case you want to sell,  throw away your hard drive / computer or have doubtful activities. If the partitions you want to delete are system (boot) partitions you’ll need to start your system with a live CD / USB such as SystemRescueCD or GParted. Finding the location of a drive or partition In order to know the exact path for your drive, you can use the fdisk command as root or sudoer: # fdisk -l Disk /dev/sda: 1887.4 GB, 1887436800000 bytes 255 heads, 63 sectors/track, 229467 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot      Start         End      Blocks   Id  System /dev/sda1               1          25      200781   83  Linux /dev/sda2              26      229335  1841932575   83  Linux /dev/sda3          229336      229465     1044225   82  Linux swap / Solaris If …

Cross-compiling FreeRDP Windows Remote Desktop Client for ARM Linux (in Debian/Ubuntu)

Last month, I wrote the instructions to Cross-compile VMWare View for ARM Linux as I intended to “run” Windows 8 in an ARM client (most likely the Raspberry Pi) via PCoIP. However, the procedure to do so seems slightly complicated and requires to purchase a specific VMWare server software (VMware vSphere 5) or download a free trial. The good news is that there are other options such as VNC or RDP (Remote Desktop protocol) and Remmina, a Remote Connection client is available for Linux. As nothing is ever simple, another issue occured: if you are using a stable release of Linux (e.g. Debian Squeeze, Ubuntu 11.10) they come with older version of Remmina and either the connection is successful but the display is garbled (Version 0.7.x) either it crashes when connecting to Windows 8 via RDP (Version 0.8.x). The latest version (Remmina 1.0.0) fixes the problem and is available in Debian sid. Since I just want to connect via RDP, …
