makeSD Script to Write Image to SD Card for Mele A1000 / AllWinner A10 Devices

Most images released for Mele A1000 (Ubuntu, Puppy Linux..) won’t fit in my SD card, and until now I had to manually partition the SD card, extract the data and copy it to the SD card. I’ve also noticed the size of the SD card slowly creeps lower overtime. I bought an SD card last week and fdisk reported 3901685760 bytes and this morning the same command reported 3898782720 bytes. That’s probably due to new bad sectors which I believe is actually normal for this type of device. The problem is that a backup of “last week” SD card done with dd might not be restored properly with dd since the SD card is now smaller. So I decided to write a shell script “makeSD.sh” that will do the following: Umount the SD card if needed Partition the SD card Copy uboot to the SD card Mount the image file […]

VWorks VLAB Powers Freescale Vybrid Virtual Platform

Back in March, Freescale announced their Vybrid solution featuring both a Cortex A5 processor and a Cortex M4 microcontroller, and they had prototypes running  an unnamed virtual platform in order to speed up software development and possibly have the software ready at the same time as the silicon is. Always looking to learn more, I studied and wrote about virtual hardware platforms such as Cadence Virtual System Platform, Wind River Simics Virtual  Platforms and the open source Imperas OVPsim simulator. It turns out Freescale does not use any of these solutions, but relies on VWorks VLAB instead, which still use the same standard (SystemC/TLM) as the virtual hardware solutions aforementioned. VWorks uploaded a demonstration of VLAB running a virtual platform for the Freescale Vybrid controller and showing how it can handle both ARM Cortex-A5 and Cortex-M4 cores. This demo of VLAB 1.7.0 is pretty interesting and showcases: Dual (virtual) display […]

Huawei K3V2 Based MediaPad 10 FHD Tablet Hands-On Video

Earlier this year, Hisilicon – a subsidary of Huawei – unveiled the K3V2 quad-core Cortex A9 processor at Mobile World Congress and Huawei showcased the Ascend Quad D Android 4.0 smartphone as well as an high-end Android ICS Tablet based on this processor called Huawei MediaPad 10 (which nobody was allowed to use). This tablet features a 1920×1080 display with a 10-point touchscreen, 1GB RAM, 32 GB Flash and a 8MP rear camera together with a 1.3MP front camera. It also comes with a 6,600 mAh battery and is only 8.8mm thick. Huawei brought the device at CTIA 2012 and Engadget could shot an hands-on video of the MediaPad 10 FHD. No release date nor pricing is available, nevertheless it’s listed for 699.99 USD on Android-Sale.com. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to […]

SCUBAPRO-UWATEC Meridian Dive Computer Powered by EFM32 Gecko Cortex M3 MCU

SCUBAPRO-UWATEC and Energy Micro have unveiled the SCUBAPRO Meridian dive computer powered by Energy Micro EFM32 Gecko MCU. Meridian is a sophisticated dive computer in a watch design, powered by a CR2032 lithium battery. The companies claim the Meridian is the world’s first 32-bit dive watch-computer. It can operate at depths of up to 120 meters, incorporates an advanced diving algorithm, performs multi-gas decompression and features an heart rate monitor that enables adaptive workload calculations. The watch computer can be used both during diving, configured to display a variety of dive information including depth, dive time, decompression status and water temperature, and above the surface where it handles remaining desaturation time, no-fly time. Its built-in thermometer and altimeter can also be used for mountain treks. The MCU used in the Meridian is the Energy Micro EFM32G890 Gecko, a 32MHz 32-bit MCU based on ARM Cortex-M3 consuming 180µA/MHz is active mode […]

This is What a Calxeda 192-Core ARM Ubuntu 12.04 Server Looks Like

Last November, Calxeda announced its 32-bit ARM Chip for servers, and now there are been some good progress as Calxeda is currently showcasing a 192-core ARM Server running Ubuntu 12.04 LTS Server edition at the Ubuntu Developer Summit in Oakland, California. The server showcased has 192 cores (48 Calxeda EnergyCore quad core Cortex-A9 processors), consumes less than 300 Watts, supports  up to 24 SATA drivers and runs Ubuntu 12.04 with OpenStack’s cloud management infrastructure. Karl Freund, Calxeda Vice President of Marketing said that the Calxeda server is running “a standard LAMP stack (running Calxeda’s website) along with other popular web frameworks such as node.js and Ruby on Rails, provisioning of OpenStack Nova compute instances, and even Canonical’s Metal-as-a-Service bare-metal provisioning.” The company also explained that a complete native build of the Ubuntu 12.04 kernel took less than an hour to build on a single node, 4 times faster than the […]

Editing AllWinner A10 Board Configuration Files (script.bin)

AllWinner A10 based devices all have board configuration files in binary format, sometimes refereed to as script.bin, evb.bin, sys_config.{product_nane}.bin store in the FAT partition with the kernel. You may want to decode those binary files to configure your hardware and/or disable/enable peripherals. For the Ubuntu image provided for the Mele A1000 set-top box, the file is called evb.bin and the two other files (mele.bin and sys_config1.mele_mod.bin) are not used. The filename can change since it is configurable in u-boot e.g.: load1=fatload mmc 0 43000000 evb.bin bootcmd=run load1 boot_mmc If you want to decrypt the binary files into text format (fex), you can retrieve bin2fex tool: git clone https://github.com/amery/sunxi-tools Build it: cd sunxi-tools make This will compile both bin2fex (binary to fex text files) and fex2bin (fex files to bin), but the later does not seem to work right now. fex2bin also works now. If you want to decrypt a configuration […]
