Infineon Hexagon Application Kit (XMC4500 Enterprise Edition) Overview and Quick Start Guide

A few months ago, Infineon sent me XMC4500 Relax Lite Kit for review, and I wrote a short Getting Started Guide about this 10 Euros Cortex M4 devkit. This month, I’ve received another XMC4500 kit with more features and expansion abilities: XMC4500 Enterprise Edition which is one of their Hexagon Application Kit. I received two packages: CPU Board XMC4500 General Purpose (CPU_45A-V2) with accessories (55 Euros) – This is what you get when you order to Basic Kit. J-Link Lite Cortex-M Debugger (40 Euros) Let’s open the packages and see what’s inside. In the first package, we’ve got XMC4500 CPU board, a pin extension board that can be used on any of the 3 extension connectors of the CPU board to access the signals easily, and a microUSB to USB cable for power. The JLink debugger comes with a 10-pin ribbon cable, and a microUSB to USB cable to connect to the […]

Linaro Connect Asia 2013 Sessions and Mini-Summits

Linaro Connect Asia 2013 (LCA13) will take place in Hong Kong again this year, on March 4 – 8, 2013 at the Gold Coast Hotel. Linaro recently published the event schedule, with sessions focused on kernel, power management, toolchain, graphics and multimedia, platform, validation, and QA tracks, as well as 2 mini-summits: Linaro Enterprise Group (LEG) which will discuss about ARM server, and an as-yet-unannounced group (Linaro Networking Group?) within Linaro. There will also be hacking sessions each day (except on “Demo Friday”) where you can certainly expect to learn many useful skills/tips. I’ve selected 2 sessions or keynotes per day that I think could be especially interesting. Some of the sessions don’t have description yet, so even if they might seem interesting I’ve usually skipped those. Monday 12:00 – 13:00 – Low Level Virtual Machine (LLVM) Update The Toolchain Working Group started working on LLVM in January 2013. Come […]

Tronsmart Prometheus Review

Now is the time to review another device sent to me by Geekbuying. Tronsmart Promotheus is an Android 4.1 Android set-top box powered by AMLogic AML8726-MX (aka AML8726-M6) with 1GB RAM and 4GB Flash, 3 USB ports, as well as Wi-Fi and Ethernet for connectivity. This device, which looks like a spaceship (my wife said it looks like a buffalo), has the potential to run XBMC with full hardware acceleration in Android and/or Linux. Tronsmart Prometheus Unboxing I’ve received the box in the package below. Apart from Promotheus media player, the package contains a 12V/1A power supply, an HDMI cable, an AV cable and a user manual in English that appears to be useful for once. It explains how to connect to device to the TV, to the networks, and to the power, how to do firmware upgrade, and how to troubleshoot it. It is presented in a way that […]

Headless Connected Oscilloscope based on Cubieboard or Beaglebone

Warsaw ELHEP (Electronics for High Eenergy Physics Experiments) Group is currently working on MMS (Mobile Measurement System) Project. This project features what I would call a “headless connected oscilloscope”, which can be detected on the network via SSDP, send the data via Websocket, and display it on iOS, Android, or Windows Phone devices. This oscilloscope does not feature any screen, and receives/transmits data via Ethernet, Wi-Fi, or Bluetooth. The original hardware is based on three main boards: CTI-VMAX – ARM9 with Wi-Fi, Bluetooth, and Ethernet connectivity. ARM SCOPE v1.0.1 with 8 channel ADC. ARM SCOPE v1.0.2 with 4 high speed ADC (100MSPS). The ELHEP researchers have been looking at replacing CTI-VMAX with low cost boards, and after considering several options, they chose to design two versions of their oscilloscope: one based on Cubieboard, and the other on the Beaglebone. So they designed expansions boards for the Cubieboard and Beaglebone in […]

Linux Conference Australia and FOSDEM 2013 Videos are Now Online

FOSDEM 2013 took place last week, and the organizers are in the process of uploading videos. Up to now, 5 main tracks sessions have been uploaded (Firefox OS; Free, open, secure and convenient communications; FreedomBox 1.0; Samba 4; and systemd, Two Years Later) as well as over 20 lightning talks. You can find the videos at http://video.fosdem.org/2013. You may also want to check my previous post for a lists of interesting talks, and I’ll probably feature some FOSDEM 2013 videos in this blog, at least the open source GPU driver talk. Linux Conference Australia took place on January 28 – February 1, 2013, and the 5-day conference featured lots of talks including several dealing with graphics in Linux, and one developer apparently trashing X in terms of complexity and performance, and explaining how Wayland was better. Others Linux sessions dealt with subject such as 3D printing, supercomputing, Arduino, big.LITTLE processing, […]

Review of Measy U2C Rockchip RK3066 Mini PC With Built-in Camera

I’ve received 2 new devices to play with this week, as Geekbuying sent me Tronsmart Promotheus set-top box and Measy U2C, a mini PC with a webcam, so that I can test and review them. Today, I’ll leave the “Spaceship” set-top box parked in another galaxy, and I will review Measy U2C mini PC. This HDMI dongle is powered by Rockchip RK3066, runs Android 4.1.1, and comes with 1 GB RAM, 8GB Flash, Wi-Fi & Bluetooth connectivity, and a built-in 2MP Webcam. For complete specs, you can check my post about B12 mini PC since this device uses the same board internally. Geekbuying sells this all-in-one mini PC for $74.99 including shipping. As usual, I’ll post some unboxing pictures, and then review the device, this time, with a section dedicated to the webcam, since this is the key selling point of this mini PC. Measy U2C Unboxing Measy U2C comes […]

Quake 3 Arena Demo Using Lima Driver is (Slightly) Faster than Mali-400 Binary Driver

As mentioned previously, Luc Verhaegen was to give a talk about the status of Lima driver (reverse-engineered Mali-200/400 GPU driver), as well as other GPU open source implementation, at FOSDEM 2013. This is now done, and part of the talk included a demo of Quake 3 Arena (q3a timedemo) running on tablet featuring AllWinner A10 SoC (Cortex A8 @ 1Ghz, Mali-400MP1 GPU @ 320 Mhz, and DDR3 memory @ 360MHz), and a 1024×600 LCD. The fact it works is already a great achievement in itself, but this demo runs at 47.2fps with Lima driver (limare), whereas it can be rendered at 46.2fps using the binary driver. In his blog, Luc also explains that apart from being 2% faster, it also uses 3% less cpu than the binary driver! Take that binary blobs! There’s still more work to do however, as this Quake 3 Arena port is not playable yet for 2 […]
