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 […]

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 […]

Kimdecent Droid Stick A2 Review

At the beginning of December 2012, I wrote a post about Droid Stick A2 mini PC based on AMLogic AML-8726-MX to show some pictures of the device, but I could not really test as the firmware was not complete, and was promise a working firmware soon. Unfortunately, things did not really go according to plans for this hardware, so the firmware never showed up… Luckily, Kimdecent found another version of the device with basically the same specs, a slightly different casing, and more importantly a “working” firmware. The company was kind enough to send me another sample for review. Droid Stick A2 Unboxing Here’s what the new Droid Stick A2 and its accessories look like. Beside Droid Stick A2 mini PC, the package contains a power adapter (5V/2A), a mini USB to USB cable, a short HDMI cable and a user’s manual in English. A close up shows the device […]

$199 Gizmo Explorer Kit Powered by AMD G-Series APU is Now Officially Available

Back in November, I came across the Gizmo Explorer Kit, an embedded development platform based on AMD G-Series G-T40E dual core APU that includes the development board itself (Gizmo Board), two expansion I/O boards, Sage SmartProbe JTAG development tool, some accessories such as cables and power supply, and a DVD with the documentation and SDK. Today, Sage Electronic, Texas Multicore Technologies, and Viosoft officially launched GizmoSphere community that aims at “fostering innovation and development for x86-based embedded Accelerated Processing Units (APUs), and driving and enabling technology projects of interest to independent developers with a focus on stimulating and encouraging innovation for existing and new applications that leverage APUs”. To help with this initiative, they also produce the Gizmo Board, and corresponding Gizmo Explorer Kit, a development board that boots with coreboot, and can run a variety of operating systems such as Android, Linux, Windows, and other RTOS. You can refer to […]

Embedded Linux Conference 2013 Schedule

The Embedded Linux Conference (ELC 2013) will take place on February 20 – 22, 2013 at Park 55 Hotel in San Francisco, California. ELC consists of 3 days of presentations, tutorials and sessions. There will be over 50 sessions during those 3 days. I’ll highlight a few sessions that I find particularly interesting, and that did not get presented at ELCE 2012 (AFAICR). February 20 11:00 – Anatomy of the arm-soc git tree by Olof Johansson, Google We are now two years into the new maintainer model for ARM platforms, and we have settled down into a workflow that maintainers have adjusted well to. Still, when new platforms arrive, or when maintainer ship changes hands, there’s sometimes a bit of ramp-up in getting used to how we organize our git tree and how we prefer to see code submitted to fit that model. This presentation will give an overview of […]
