Droid Stick A2 Firmware With Google Play Fix

If you have read my previous review of the Droid Stick A2, I was pretty upset about Google Play since I could not install most of the apps. This is now fixed, and Kimdecent has released a firmware upgrade. Here’s how to upgrade: Download g02refDongle-ota-20130201.rar Extract it in your PC, and copy the files (g02refDongle-ota-20130201.zip and uImage_recovery) to the root of your microSD card (Formatted as FAT32) Insert the microSD into Droid Stick A2 Boot the mini PC normally, and launch the “Upgrade” app Select Local Upgrade, then select g02refDongle-ota-20130201.zip and click on Reboot and Install Package Droid Stick A2 will reboot, and it should start upgrading Android. Done Since I’ve been messing up with Android and broken something, “Reboot and Install Package” does nothing for me (some permissions issues with /cache/recovery/command), so I could not verify this works or not. Finally, I could install it on the first version […]

Red Raspberry Pi Board is Now Available in China

If you have a Raspberry Pi, most likely it will have a green PCB since that’s the way they are manufactured it. The good news is that the Raspberry Pi is be available in its natural color Red very soon, however it will only be officially sold in mainland China, Hong Kong, Macau and Taiwan. The reason for the geographical limitation is because Farnell and RS components have a worldwide co-exclusive license to sell the Raspberry Pi, and the selected Chinese manufacturer, Egoman Technology Corp , won’t be allowed to sell out of China. However, it will be hard to prevent third parties in China from buying the product, and selling it via Ebay or Aliexpress. The other reason for the differentiation is that the Red Raspberry Pi won’t be CE/FCC certified, even though, at the beginning, at least it will basically have the same components of the Green Raspberry […]

Replicate CAPE Adds 3D Printring Capability to the Beaglebone

Beagleboard.org launched the Beaglebone Cape Design Contest back in November, several designs were submitted, and yesterday, they announced the 3 winning CAPEs who will be manufactured and sold by Circuitco Electronics: Replicape by Elias Bakken – 3D printer cape Interacto by Chris Clark – Cape with a triple axis accelerometer,a gyroscope, a magnetometer and a 640×480 30fps camera. Geiger cape by Matt Ranostay – Geiger counter cape Since today I’ve started to write about 3D printing, let’s carry on and have a closer look at the Replicape. The Replicape 3D printer cape includes: 5 stepper motors (X, Y, Z, Ext1, Ext2) 3 high power MOSFETs (PWM controlled) for 2 extruders and 1 HPB 3 medium power MOSFETs (PWM controlled) for up to 3 fans 3 analog input ports for thermistors 3 inputs for end stops (X, Y, Z) Programmable current limits on steppers motor drivers (SMD). No need to manually adjust […]

3D Systems Cube and CubeX 3D Printers and Cubify Online Service

3D Systems was at CES 2013 to showcase their 3D printers, and their online 3D printing ecosystem called Cubify, where you can design your own model, order the object to be 3D printed, which is then shipped to your door. They have 2 printers that are available for the home market: Cube 3D printer ($1,399) Print size: 140 x 140 x 140 mm / Resolution: 200 microns CubeX 3D printer ($2,799 to $4,399) Print size: 275 mm x 265 mm x 240 mm / Resolution: 125 microns. The CubeX can support 1, 2, or 3 printer heads in order to print objects with multiple colors and/or materials. Charbax shot a video with the company, and I’ve learnt quite a few interesting things about 3D printing: It’s been around for nearly 30 years, but only used by the industry until recently. 3D printing takes a lot of time. The small spaceship […]

A Selection of FOSDEM 2013 Events

FOSDEM is a 2-day (or 3 if you include Friday beer event) event where over 5,000 members of open source communities meet, share ideas and collaborate. It’s free to attend, and there’s no registration, so you just show up to attend. FOSDEM 2013 takes place on Feb 2-3 (yep, this week-end) in Brussels There are 7 main tracks where sessions are organized: Operating systems Open source challenges Security Janson Beyond operating systems Web development Miscellaneous Robotics There are also keynotes and devroom for a total of 488 sessions. Developers rooms that may particularly be of interest to readers of this blog are: Cross Desktop devroom – e.g. Wayland, gstreamer, razor-qt, Qt Project, Plasma Active, etc… Cross Distro devroom – e.g. Linux on Android, suse on ARM, ARMv8, systemd, etc… Embedded and mobile devroom – e.g. Baserock Embedded Linux, Guacamayo (Yocto), Nemo Mobile/ Mer project, arduino… All in all that’s a […]

Linaro 13.01 Release with Linux Kernel 3.8 and Android 4.2.1

Linaro has just announced release 13.01 which includes Linux Kernel 3.8-rc4 and Android 4.2.1. A lot of work seems to have gone in Arndale board and OpenEmbedded ARMv8. It’s the first time an Ubuntu image is released for Arndale Cortex A15 development board. One the kernel side some Android upstreaming work has been done, as well as some fixes for eMMC, and code for ST Ericsson Novathor 8500 SoC has been reorganized. Version 14 of the big.LITTLE MP (Multi Processing) has been released. The LEG has done further work on Linaro UEFI and GRUB. Here are the highlights of this release: Android Platform Work The first step of the android-build front-end update for new build program has been landed. Origen and Versatile Express manifests have been consolidated into a single manifest. linaro-android-tools were developed to improve development time for kernel developers. See Kernel Update Tools for details. The android-build scripts […]

ARM MCU Development in Linux with Energy Micro’s Simplicity Studio, Eclipse, and CodeSourcery Toolchain

Quite a few months ago, I received an Energy Micro EFM32 Tiny Gecko Starter Kit, but I haven’t done much with it. But recently I saw a tweet from EnergyMicro about Simplicity Studio supports for Ubuntu, and I know it can be problematic to find proper tools for ARM MCU development in Linux, so I decided to give it a try. The first part is about Simplicity Studio, and energyAwareTools which are specific to Energy Micro, but the second part deals with setting up Eclipse and CodeSourcery ARM toolchain for MCU development which should be reusable for other MCUs from vendors such as Texas Instruments, NXP and STMicro. I’ve used a PC running Ubuntu 12.04 64-bit with the instructions below. Installing Simplicity Studio and energyAwareTools in Ubuntu Simplicity Studio is part of the 4 steps of the getting started guide with EFM32 MCUs. It has been available for Linux for […]

How to Access the Serial Console in MK808 mini PC

Omegamoon has done a pretty neat hack on MK808 Rockchip RK3066 mini PC to connect a Sparkfun USB to TLL board and access the serial console for bootloader and kernel debugging. The first thing he had to do was to open the device, remove the heatsink, and locate the Rx/Tx pads on the board. The Rx and Tx pins are accessible through pads, not via through holes, so it’s just a little more difficult to solder, but nothing too challenging. He and his brother also soldered another cable to the ground. Then they inserted a 6-pin header via the ventilation holes of the device, soldered the 3 wires to the header, and fix the latter to the casing. Finally, they just inserted the debug board in the pin header, connected the USB cable to their PC, and started minicom (or equivalent) to start accessing the serial console. I think that […]
