I am really excited about some recent work by Marcin on starting a u-boot and Linux kernel port to the Mediatek MT6235 baseband processor. Among GSM baseband processors, the MT6235 is a very unusual device. Unlike classic GSM baseband chips, it ... [More] is not based on an MMU-less ARM7TDMI/ARM7EJS but on an ARM926EJS core. This is a full-blown ARMv5 core on which a standard Linux kernel could run. The reason for the MT6235 to contain such an 'advanced' ARM core is simple: Mediatek is producing chipsets and reference designs for very inexpensive but feature-rich phones. Instead of going to a full-blown (and expensive) smart-phone design with separate ARM cores for the baseband and application processor, they simply make the base-band processor a bit stronger than needed for the GSM stack, and run the entire rich UI on the same cpu, including TCP/IP stack, touch-screen, web browser, e-mail client, H.264 playback / camera recording, etc. The original firmware on the Mediatek chipsets is a Nucleus-kernel based software stack which is completely proprietary. Now the mid-term vision for us is to have a Linux port to the MT6235, and run the OsmocomBB Layer1 (and possibly Layer2) code inside the kernel, while the Layer3 and a user interface program is running as application programs in userspace. This would allow us to do a very rich user interface (imagine network monitoring modes, protocol tracing, manual cell selection, etc.) while still having to care only about one processor in the system. Furthermore, there are millions of MT6235 based devices, so there will be no shortage of inexpensive hardware to run this code on. The MT6235 also has a built-in SD/MMC controller (for storing e.g. protocol traces that you take from the GSM network) and it has a fast, dual-mode USB2 high-speed USB controller for connecting it with a PC Sure, porting our Layer1 to a completely different baseband chipset will be a lot of work, and I don't really have any idea how long it will take us. But I think the vision of such a powerful device (and finally bringing OsmocomBB and the Linux kernel together) should prove a very attractive motivational factor. This also means: Even if you have no clue about the GSM protocols, you can now start to contribute to OsmocomBB: A lot of Linux kernel drivers for e.g. SD/MMC, USB, frame-buffer, SPI, I2C, PWM and other integrated controllers of the MT6235 need to be written. Like all Mediatek data sheets, the MT6235 data sheet describing all those peripherals can be found on various places on the Web, including (but not limited to) Chinese developer forums. It also seems there is at least one MT6235 based phone where JTAG and serial console have been identified (Sciphone Dream G2), which should make debugging and bootstrapping convenient. [Less]

In my desperate attempt to understand the interworkings of the mechanical watch, I enrolled in a online course and purchased a watchmaker’s tool set with a ETA 2801 movement.

Just looking at the gears move makes me feel like I’m witnessing the creation of time itself. [Less]

Casey Reas, Chandler McWilliams, and LUST released a new book entitled “Form+Code”: It’s a look at computational aesthetics in the fields of design, art, and architecture. Specially the book is about how software allows for new “forms” to be created ... [More] in the visual arts. For some of us, coding is second nature, just another form of thinking. But for many, it’s completely foreign – more incomprehensible than Shakespeare. Ever since I learned BASIC on my first computer, I’ve been magnetically drawn to the visual side of computation. “Why code?” was a question friends frequently asked. I was never able to really express why. Even though, like a learning a second language, I always believed it was important for personal growth – especially for those in visual / conceptual fields. I love what this book has to say: Learning to program and to engage the computer more directly with code opens the possibility of not only cresting tools, but also systems, environments, and entirely new modes of expression. It is here that the computer ceases to be a tool and instead becomes a medium. Learning to program and to engage the computer more directly with codeopens the possibility of not only cresting tools, but also systems, environments, and entirely new modes of expression. It is here that the computer ceases to be tool and instead becomes a medium. “Code+Form” is full color and bursting with examples. Take Flatware: A new set of flatware designed, “by mutating, blending, and evolving a base form” for example: Recursion is topic of great personal interest. Here’s a section from the book: And Flight Patterns, by Aaron Koblin, is breathtakingly gorgeous illustration plotting the paths of aircraft across the United States: If you would like to read this book, tell three people about my company’s latest project, WikiReader, and then send me an email.

Howdy, dear reader! It’s been a while on this blog, mainly due to the fact that many short status updates are better twittered than blogged. Then again, as promised / threatened in last year’s installment of this column, I had to spend most of the ... [More] time this year with iOS development, rather than with FOSS — and it doesn’t look like this will change much (you know, food and things…). Still I do care a lot about projects like OpenEmbedded, Vala, freesmartphone.org, and the like, so here’s what has been going on this year: OpenEmbedded (www.openembedded.org) OE moved along quite well this year. I did not have much time for it — other than taking care about a couple of Vala and FSO recipes — but I’m especially pleased that the community finally embraced major clean up. Thanks to Frans, Richard, and all others involved, OE is improving heavily — although it wasn’t easy: Over the last couple of years, the OE core contributors developed a resistance against any changes affecting more than a handfull of recipes, however in order to make OE handle even more contributors and various use cases, we had to do some substantial cleanups. This will reduce maintenance and improve the overall quality of recipes in OE, which is the #1 complaint I hear. Vala (www.vala-project.org) During the first half of the year, Vala went through some extremely tiring phases of non-activity, which improved vastly when its main developers opened up a bit, i.e. giving more developers access to the tree, adding branches, etc. There have been many changes in the Dova profile, but also the GLib profile has seen an incredible amount of work, bugfixes, some new features, and more. The pace of changes that affect basic things had also impact on my vala-book plans; apart from a severe lack of time on my side, I think it’s better to wait until Vala is closer to 1.0. Otherwise I risk describing a moving target, which — considering the time I have to work on that project — would effectively kill it. That said, it’s great to see that Vala is getting better every day and gains more and more popularity from all kinds of developers. FSO (freesmartphone.org) The progress on freesmartphone.org is two-fold; on one hand, we have seen quite a nice amount of work to support more devices. On the other hand though, in contrast to all the work I did in 2009, there has been a severe lack of development of the core in 2010. This I plan to change as soon as possible. For 2011, I see myself continuing to develop FSO in the following three dimensions; internal, external, and integration. Internal | FSO is a heavy DBus consumer. I think by now we are one of the largest projects using DBus, at least considering the amount of API and running processes that communicate with each other via DBus. We always had our share of problems with DBus, especially some concurrency problems and race conditions are still haunting us. Both libdbus and dbus-glib exhibit their own share of problems, obviously this is not much of an issue on the desktop, but it turns out to be a major PITA on embedded systems, such as a phone. That’s why I have been excited since I heard that the glib team planned to write their own DBus backend and put it right into the glib. This work has now been released as of glib 2.26. Over the next weeks, I will port FSO to using gdbus in a branch. External | DBus-signals have some problems. That’s why some big projects (BlueZ and ConnMan, to name two of them) adopted an agent-style of API, where the clients have to implement a server API which is being called by the actual servers. While this means some more work for client developers, it has major benefits. I’m going to change some of our APIs to adopt this style. Integration | To deliver an integrated solution for today’s mobile phones, FSO needs to add more glue to work with existing services, such as BlueZ (bluetooth connectivity), Connman (ethernet and wifi connectivity), and some VoIP services. While these services work fine on their own, FSO lacks an API that uses these individual services in combination to achieve higher level tasks. All this means that I will not be working much on the actual ports, but rather use my — very limited, did I say that yet? — time to drive the core forwards. I still believe that we will have full FOSS phones — other than the Openmoko devices — soon. Please help to make this dream a reality. (And no, please don’t talk to me about Android…) Cheers, :M: [Less]
