If you encounter a problem with running Python [python] scripts on a “bare” Blender Player [blender], make sure that both PYTHONHOME and PYTHONPATH are set correctly to match your needs. You can also use native Blender python with a simple shell script:

#!/bin/sh
export PYTHONHOME="/path/to/blender/python/"
export PYTHONPATH=$PYTHONHOME"/bin"
/path/to/your/blenderplayer $@

It is my great pleasure to inform you folks that, almost after four years, I did a new release of LibSWD-0.7 [1], a low-level embedded systems access open framework. Special thanks goes to Andrew Parlane of Carallon Ltd [2] for his much appreciated contributions! Well now I feel like I need to invent some nice small device based on ARM Cortex-M0 CPU :-)

I have recently started the OrangeADE project [1], that is Orange Autonomous Device Evaluation, an online platform to evaluate security level of network equipment and verify against known vulnerabilities. OrangeADE is released as Open-Source under the “new” 3-Clause BSD license. Enjoy the work in progress! :-)

Why only NEXUS devices are sensible choice for Advanced Android Users and Developers? Because NEXUS device vendors provide source code and device drivers.

This makes is possible to re-compile and re-create any customization of the Android by advanced users and developers. The most popular among them is CyanogenMod based on AOSP (Android Open Source Project).

Why is such customization really necessary? Because Vendors does not keep up with the Android development, their releases are flawed, contains unwanted modifications, quite often development is abandoned just after product release.

I know that Drivers Development is time and money consuming task for Vendors. Still, providing source code for device drivers would make it possible to run alternative and/or customized OS, also prolong device life for second-hand users in poor countries. Vendor sells the device anyway and Users can make fixes and customization. Why this Win-Win scheme is so hard to achieve in reality? Is really enforcing sales with mass garbage so important?

When you setup system on a fresh disk you may encounter a problem of corrupted GPT backup. This will happen even more likely when you messed with MBR before on that disk. Free and Open GDISK utility will help you. GDISK will tell you current state of the disk and partition tables, also warn you on possible problems. When you print available partitions (‘p’) and they seem okay, you can simply write out (‘w’) the partition table, that would fix the GPT backup corruption problem :-)

Heimdall is an Open-Source utility to work with Android devices manufactured by Samsung. It allows to flash firmware components into memory via FastBoot/ODIN+USB. I have created a patch to build this nice tool on FreeBSD OS (QT gui works as well, to build it you need qt-{gui,qmake,uic,moc,rcc,…} packages installed). When patch is included into the project sources and release is done, I will prepare a FreeBSD port for this nice utility which is only missing a memory dump and live boot to be totally perfect :-)

I am happy to announce a new release of LibSWD-0.6! Most important feature of this release is the standalone Application with an example of Command Line Interface (CLI), FTDI driver and ARM Cortex-M3 Core Debug and Flash support demonstration. Please report issues via Ticket System. Have fun! :-)

I have created a simple patch for FreeBSD Operating System to detect and support FT2232H based KT-LINK interface. FTDI chips are already supported using uftdi driver and they can provide various serial and parallel protocols over USB such as RS232, JTAG, SWD, SPI, I2C, 1Wire, etc. My patch allows to use RS232 port on the KT-LINK which in conjunction with Minicom terminal software allows to talk to the Serial Console Port on various embedded systems. KT-LINK is really nice inexpensive (50EUR) and versatile tool for embedded system developers, now it became all-in-one tool on my FreeBSD box :-)

I have found very simple solution on how to access YouTube videos that require Flash using HTML5 player. Although front site may not support HTML5 video player, YouTube usually allows to embed videos to other sites, they also should use WebM codec developed by Google. If you have a video that does not work in HTML5 by default try to run it in embed player by URL modification – replace “/watch?v=” with “/embed/” and it should work! :-)

Patches that integrate LibSWD with OpenOCD has been already sent, so the platform independent Serial Wire Debug in Open-Source becomes a reality! Mr. Gerrit takes care of the source code review part, while Mr. Jenkins takes care of proper binary build for various platforms and operating systems. This is the right moment to make use of developers mailing list for feedback, asking questions, blaming, testing, adding new features and voting to accept the patches, so the code becomes an integral part of the OpenOCD release!

Orange Labs provided R&D environment for initial stages of the research. Warsaw University of Technology made this possible as part of my MSc and PhD thesis. Krzysztof Kajstura designed and provided his generic KT-LINK (FT2232H based) interface to work with. David Brownell first introduced the Transport layer in OpenOCD in 2010 to split Target from JTAG. Simon Qian was working in parallel on his own SWD implementation for a Versaloon interface (as part of intelligent firmware). Øyvind Harboe, Peter Stuge, Spencer Oliver, Rodrigo Rosa helped me on GIT usage and OpenOCD internals,  Freddie Chopin helped me a lot with commited patches to match OpenOCD coding standards, Akos Vandra helped me to test functionality as the program was created… and my other friends should be also noted here for their support :-)

Power of the few outweights power of the many! Thank you for your support! :-)

I am happy to notice slow withdrawal of closed-source solutions such as Adobe Flash (and so available only on selected platforms) from the web. When I have working Open-Source and (mostly) BSD-based web browser (Chromium) with some commercial support (Google) at least to display H264 encoded multimedia content (using Open-Source x264 software implementation), and there is HTML5, I start to consider Vimeo a better option than Google’s YouTube, if we speak of quality.

Although Google develops Open and Free multimedia codec called WebM, at the same time they use annoying commercials that makes WebM-ready videos unavailable in most cases on HTML5 YouTube and push users towards Flash anyway, as opposed to Vimeo where all H264 videos works flawlessly in HTML5…

I was even more surprised to see for the first time a very colorful, scalable, interactive and full of multimedia content website of Jennifer Vaughn (created by Phil Giampi) that use NO closed-source Adobe Flash at all!! This website works flawlessly in Chromium browser on my FreeBSD Unix style desktop which use only Open-Source and Free-Software components and embeds Vimeo content. Thank you for supporting high quality open web (although its not totally free)! :-)

What about WebM? Google at one hand creates Free and Open standard such as WebM, but on the other hand Google does not seem to support it at all – neither in its own projects (see advertising with Flash on YouTube that blocks HTML5) nor in external projects (see Mozilla/Firefox struggling alone to promote WebM, see Google Chrome that simply buys restricted H264 license and thus promotes the competitive standard). I think it might be cheaper for Google to make H264/X264 free to use (at least as renderer like Microsoft did) rather than investing into something that is not going to be used anyway… What is the internal organization of Google? Do people need to fight for their projects against each other inside? Why there is no global view for better coordination? This seems to be a great waste of energy, WebM seemed to be very promising Free and Open Standard :-(

LibSWD 0.5 is out! It brings mainly the rename of all function prefix due API conflicts with other existing solutions.

Please visit Project Website for more information :-)

LibSWD 0.4 is out! It brings various bugfixes and improvements, but most of all stable API to be used with OpenOCD and other external applications.

See Project Website for more information :-)

“LibSWD serial wire debug open framework for low-level embedded systems access” has been presented on FedCSIS 2012 international conference and the paper has been already published by IEEE Xplore Digital Library.

All my publications are listed on Google Scholar.

I have started my works on implementing the Serial Wire Debug (kind of JTAG alternative for ARM-Cortex Cores) for Open-Source OpenOCD and UrJTAG utilities. You can watch the progress at:

http://stm32primer2swd.sf.net

Project type: Open
Status: Work in progress…

My port of OpenOCD has just been committed. Enjoy Open On-Chip-Debugger on FreeBSD! =)
