Droid Stick A2 – AMLogic AML8726-MX Dual Core Android 4.1.1 mini PC

Since it was first announced in August, Rockchip RK3066 dual core mini PCs have been popping up everywhere, and AFAIK those are currently the only low cost (sub $100) dual core Android TV Sticks available. But according to a recent Kimdecent announcement, this is about to change with the release of the Droid Stick A2 based on AMLogic AML8726-MX Dual Core Cortex A9 processor with 1GB RAM and 4 to 8 GB Flash running Android Jelly Bean. Here are Droid Stick A2 specifications: CPU – Amlogic AML8726-MX Dual Core Cortex A9 @ 1.5 GHz GPU – Mali400 Dual Core, 2D/ 3D/ OpenGL ES2.0/ OpenVG1.1. System Memory – 1 GB RAM Storage – 4/8 GB Nand Flash + microSD card slot (up to 32GB) WiFi – 802.11b/g/n Video Output – HDMI (1080P) Video Decoding – Supports up to  1920x1080p@60fps Video Encoding – Supports encoding in H.264. 1080p@60fps, 720@100fps USB – 1xUSB […]

$69 – $89 Wandboard Freescale i.MX6 Solo and Dual Development Boards

The Wandboard is a low cost Linux ARM Cortex-A9 ARM board comprised of a  CPU module and an interface board. There are actually 2 versions of the board (single and dual core) which are developed by a team of engineers during their spare time: Wandboard Solo – $69 – Freescale i.MX6 Solo + 512 MB RAM Wandboard Dual – $89 – Freescale i.MX6 Dual + 1 GB RAM Both boards come with Audio I/O, Optical S/PDIF, HDMI, a camera interface, 2 micro SD cardslot, a serial port, an expansion header, USB and USB OTG ports, a SATA connector and Gb Ethernet. The dual version also adds Wifi 802.11 b/g/n and Bluetooth support. There are not so many boards with native SATA support, so for those of you who need SATA this could be really be a good option. [Update: Although there’s a SATA connector on the baseboard, this is not […]

FPU and Memory Android Benchmarks: RgbenchMM & RgBandwidth

There are already a fair amount of Android benchmarks such as Antutu or Quadrant, but how those benchmarks work exactly is unclear and the number they return have no direct meaning, until you start comparing results to other device results. This is why Rahul Garg, a PhD student at McGill University, has written 2 new benchmarks to test FPU and memory bandwidth with known benchmark procedures and results in MFlops and MB/s which are both available on Google Play Store: RgbenchMM– A benchmark to test the floating point performance performing double-precision matrix multiplication and fully multi-threaded to support multiple cores. It’s programmed in C++ using Android NDK, and works with ARM and x86 devices running Android 2.3.3 and greater. RgBandwidth– Asimple memory bandwidth test which tests memory copy performance (in “Simple” mode), and uses tests derived from the STREAM benchmark (“Misc” tests). This can be used to get an estimate […]

Linaro 12.09 Release with Kernel 3.6 and Android 4.1.1

Linaro release 12.09 has just been announced, and includes Linux Kernel 3.6-rc6 and Android Jelly Bean. This release provides further improvement to Android Jelly Bean, Android benchmark characterization,  an ARMv8 OpenEmbedded image, UEFI bootloader support for Vexpress, origen and pandabords, and some improvement to big.LITTLE and power management. Here are the highlights of the release: Android All Linaro patches are now available on Jelly Bean. Accelerated graphics is now available on Snowball Jelly Bean build. AndEBench, AndEBench Java, Linpack, CaffeineMark, Antutu 2D and 3D, NBench, Quadrant, I/O Benchmark, Vellamo benchmark hotspot characterization available. An Origen tracking build is available and will be released this cycle as a Linaro Evaluation Build (LEB). Audio works on Origen running Jelly Bean (WAV file only). A Monkeyrunner script to run Streamline has been completed. First rev of the NI PXIe-4154 based power measurement system is created. See http://www.youtube.com/watch?v=9bKyuxLl4iw&feature=plcp In-tree AOSP tests have been automated. […]

uClinux on Cortex-M3/M4 MCU: The Costs, Performance and Power Consumption

I previously wrote about different options available to run Linux on Cortex M3 & M4 Microcontrollers, and more recently Vladimir Khusainov, co-founder and Director of Engineering at Emcraft Systems,wrote a longish article entitled “Practical Advice on Running uClinux on Cortex-M3/M4” on electronicdesign.com, where he explains how SoM are usually selected, the costs of running uClinux on Cortex M3/M4 MCUs such as Freescale K70 or STmicroelectronics STM32F2/F4, as well as performance and power consumption considerations. First, Vladimir addresses one comment that says there’s basically no use for uClinux on Cortex M3/M4 MCU, since external memory is needed and an ARM7/ARM9 modules (with MMU) can be purchased for almost the same price.  There are 2 counter arguments to this point of view: In practice, customers usually select an hardware platform first, then think what OS can be used on the platform. For example, if a company decided to use an hardware based […]

$25 Outbreak Galago – Cortex M3 Open Hardware Development Kit

Outbreak Galago is a tiny development kit based on a Cortex M3 processor that fits a debugger, and is destined for rapid electronics prototyping. The company promotes it as some sort of Arduino board on steroid (MCU wise) and sells for $25 on kickstarter, and less than $10 in 10k quantities. Here are the board specifications: 72 MHz 32-bit ARM CPU with 32KB of flash ROM and 8KB of RAM (NXP LPC1313 TBC) Integrated hardware debugger One high-speed SPI port, up to 36 Mbps One high-speed I2C port, up to 1.5 Mbps One UART/USART with hardware flow-control capability, up to 256 kbps 10 high-speed PWM pins, 6 driven by 32-bit (high-resolution) timers 6 ADC (analog) input pins with 10-bit resolution at over 400 KSa/sec 25 GPIO (digital) input/output pins The form factor and built-in debugger (via USB) are not really new, as those are already featured in devkit such as TI Piccolo controlSTICK, […]

UG802 Android mini PC Unboxing and Review

Leo, a reader of this blog who seems to be indirectly involved in togetho.ru, has written a review for UG802 dual core mini PC in Russian. He has allowed me to post the review in English,  and I wrote condensed review in English which you can read below. UGoos UG802 is sent in the following package that clearly shows it’s based on Rockchip RK3066 processor. Now let’s see what’s inside the package. There’s the UG802 TV stick, a female to male HDMI cable (which appears to be too short as usual) and a USB cable to power the device. UG802 is not the smallest mini-PC around as you can see from the picture on the right where it is compared to a flash drive, but it weights just 31g, has a lot of ventilation holes, and features an HDMI male connector, a microSD card slot, microUSB and USB ports.

Building Kernel Modules for AllWinner A10 Android Devices (e.g. Joystick Support)

Reader JP has enabled Joystick support in Android 4.0.4 on its Mele A1000, this now works with a Playstation2 joystick via USB adapter, a Huskee PC joystick, and 2 other unbranded joysticks. In order to enable Joystick support he had to build a kernel module, and encountered a few issues, so he wrote an how-to which shows what challenges he went through and what solutions he found to those issues.I’m sharing today a slightly edited version of this how-to. This How-to assumes that you have a valid Linux environment where you can build allwinner A10 kernel. The toolchain used was “Sourcery CodeBench for ARM GNU/Linux Lite“ which can be downloaded here: http://www.codesourcery.com/sgpp/lite/arm/portal/package7853/public/arm-none-linux-gnueabi/arm-2010.09-50-arm-none-linux-gnueabi.bin To install it, simply run:

You’ll also need the latest Allwinner A10 kernel source:

Then follow the usual procedure:

I then selected the modules needed for different kind of joysticks namely:

I saved the […]
