Mele A1000: AllWinner A10 (Cortex A8) Based Hackable Android STB

The Mele A1000 is an Android 2.3 IP Set-top Box (STB) powered by AllWinner A10 (Cortex A8) CPU with 512 MB RAM and 2 GB NAND Flash. AllWinner A10 is the CPU to be used by the 15 USD (BOM Cost) Rhombus Tech Linux Computer, an alternative to the Raspberry-Pi. Since they do not have an alpha board yet, the Mele A1000 STB is apparently the development platform chosen by developers involved in Rhombus Tech low cost board while they wait for the hardware. Let’s have a look at the device specifications: CPU: ARM CortexA8 1GHz (AllWinner A10) Memory: DDR3 512MB RAM / 2 4GB Nand Flash OS System: Android 2.3 External Storage: Supports SD card up to 32GB, supports 2.5″ SATA HDD up to 1TB, Supports max 16GB USB flash disk Video coding: HD MPEG1/2/4.H.264.HD AVC/VC-1,RM/RMVB, Xvid/DviX4/5/6, RealVideo8/9/10, VP6 Video Format: ts/m2ts/tp/trp/mkv/mp4/mov/avi/rm/rmvb/wmv/vob/asf/flv/dat/mpf/mpeg Audio Format: MP3/WMA/WMV/OGG/FLAC/MKV Subtitle Format: SRT/SMI/SSA/ASS Network […]

uClinux Running on Freescale Kinetis K70 MCU (Cortex-M4) Module

Last year, I posted about Linux for Cortex M3 & M4 Micro-controllers and noted it was difficult to find cost effective Cortex-M based boards able to run uClinux or Linux (RAM being the main issue). Freescale TWR-K70F120M is a module based on Kinetis K70 MCU (Cortex M-4) with plenty of RAM (128MB) to run Linux or uClinux. It is available for 109 USD or 179 USD with Freescale Tower system (TWR-K70F120M-KIT). Here are the key features of the module: Freescale MK70FN1M0VMJ12 Cortex-M4 MCU @ 120 MHz (Product Brief) Touch Tower Plug-in Socket General purpose Tower Plug-in (TWRPI) socket On-board JTAG debug circuit (OSJTAG) with virtual serial port 128 MB DDR2 SDRAM memory 256 MB SLC NAND flash memory Three axis accelerometer (MMA8451Q) Potentiometer Micro-SD Card slot I could not find an open source uClinux implementation for Kinetis K70, but emCraft has a Linux Board Support Package (BSP) for the Freescale TWR-K70F120M-KIT […]

Linux 3.3 Release

Linux Torvalds announced the release of Linux Kernel 3.3 on the 18th of March: So after the extra -rc release last weekend, now the final 3.3 is out there in the usual locations. Things did indeed calm down during the last week, and the shortlog looks pretty boring. The diffstat from -rc7 is dominated by the arch/tile defconfig changes, the rest is pretty small, although there are changes spread out in various subsystems (drivers, filesystem, networking, perf tools). … And obviously, the 3.3 release means that the merge window for 3.4 is now open, although I may keep of pulling stuff for a day or so to encourage people to test the actual release. Linux 3.2 brought ext-4 and btrfs file system improvements, support for Qualcomm Hexagon processor, an improved profiling tool (perf top), and better CPU and network bandwidth management. Linux 3.3 brings the following key changes: Android merge: […]

98 Raspberry Pi Boards Left for Qt Developers

In November 2011, the Raspberry Pi foundation announced that Nokia purchased codes for 400 boards from the 1st 10,000 batch, in order to give them away to selected developers that are interested in helping develop and test Qt 5 on the Raspberry Pi. This developer program is called QtonPi. The surprising part if that they struggle to distribute all those boards. Although to date 425 people have been selected, only 302 are currently eligible to receive a board because over 100 developers did not provide their details to receive the free Raspberry Pi board namely: Their full name The link to their wiki user profile. The area of the “QtonPi Accepted Page” where they are listed. The country where the board will be shipped If by chance, you are reading this blog, have been selected but you can’t see “OK” or “CODE SENT” next to your user ID, you should […]

A Novel Approach to In-Vehicle Infotainment (IVI) – Android Builder Summit 2012

Thomas B. Rücker, Program Manager at Tieto, discusses In-Vehicle Infotainment (IVI) with Android at the Android Builder Summit in February 2012. Abstract: In the future vehicles are going to be always online. The constantly increasing number of electronic devices raises consumer expectations. Both driver and passengers want to be online. This requires new and flexible IVI and HMI solutions. Users expect intuitive and simple to operate interfaces, but at the same time they expect the systems to handle a lot of their data and apps. We are witnessing a paradigm shift in Infotainment solutions. Open software platforms will allow users to add new functionality and services, also by third parties, over the whole life-span of a product. This requires solutions that reconcile the multi-media world of consumers with traffic security requirements, in a cost effective and secure hardware platform. The presentation will highlight challenges and opportunities by bringing Android to […]

Archos G10 xs Teaser Video with Sliding Keyboard Dock

Archos has just released a teaser video for its next generation Android tablet, the Archos G10 xs (xs stands for extra small). The video does not show much, except the concept of the new tablet which features a sliding keyboard where the tablet can be docked. Archos has not released the specifications for the G10 XS yet, but we do know the casing is made of stainless steel, is 7.6mm thick (12mm with the keyboard) and Archos has worked for 3 years on this design. There will be several models whose retail price should be between 200 and 300 Euros (Which would be between 200 and 300 USD in the US thanks to lower taxes). The new tablets will be powered by a Texas Instruments processor (probably OMAP 4) like the Archos G9 tablets and run Android 4.0 and Windows 8 depending on the model.

Using OpenOCD JTAG in Android Kernel Debugging – Android Builder Summit 2012

Mike Anderson, CTO and Chief Scientist for The PTR Group, gives a tutorial about Linux kernel debugging in Android with OpenOCD JTAG at the Android Builder Summit in February 2012. Abstract: Owing to the use of the Linux kernel, Android device drivers can be debugged using many of the same techniques as Linux. Still, much of the user-space interface code typically found in Linux is missing in Android. This complicates the debugging of kernel driver code. This presentation will demonstrate the use of the open on-chip debug (OpenOCD) software and an inexpensive JTAG to debug Android kernel code. The target audience for this presentation are platform developers looking to debug their kernel code such as device drivers. This presentation is targeted at intermediate-level developers with some understanding of kernel code development. You can also download the presentation slides on linuxfoundation.org website.

Android Device Porting Tutorial – Android Builder Summit 2012

Benjamin Zores, Open Source Software and Multimedia Architect at Alcatel-Lucent, gives step-by-step to port Android to your own device at Android Builder Summit in February 2012. Abstract: This talk is presented as a step by step tutorial meant for Android platform rookies, as to discover all Androidisms one has to tackle down to bring his own custom device to life. Based on a real-life Android 4.0 ICS device porting experience, the talk will cover early board bringup (from U-Boot and Fastboot to Linux kernel and drivers), AOSP device integration, Android-specific device init customization, touchscreen input layer adaptations and Hardware Abstraction Layer (HAL) driver interfaces development.
