Some of you are bound to have realized that there is a new update for the N900, PR1.3. This is primarily a consumer update containing many tweaks and improvements to the N900 user experience. It also aligns the Qt application and UI framework with the planned version for the MeeGo 1.1 platform (Qt 4.7).  Qt Mobility 1.0.2 APIs for mobile development are also included.

Software development using scratchbox for the new platform will be supported right away.  For those using the Nokia Qt SDK, we have tested Qt 4.6 applications on PR1.3 and did not encounter any major problems, so you can continue to distribute apps developed with the current toolset. Support for new N900 apps with the Qt4.7 framework will be available with a Nokia Qt SDK update that will be available soon.   Until then, Ovi Store will accept applications built using Qt4.6.

Qt 4.7 comes with Qt Declarative libraries and QML support. This cutting edge technology allows the fast creation of impressive application UIs.  It also supports interaction with C++ objects, allowing developers to create dynamic UIs in QML and link them to background C++ code.  There have been many examples of Qt Quick already posted at maemo.org and at qt.nokia.com.  Full Qt Creator support for Qt Quick development will be available when Nokia Qt SDK 1.1 is released.

Video: Maemo 5 alpha on BeagleBoard

Here’s a quick video I put together while learning to use the video cam (you’ll notice that pretty soon) 🙂 This is just a basic demonstration of how the Maemo 5 alpha SDK runs on the BeagleBoard. Sorry about the video quality, I’ll make a better one from the eventual Maemo 5 Beta release.. promise!

Check out the Maemo on BeagleBoard site for more information.

Maemo 5 alpha on BeagleBoard

After the release of the Maemo 5 alpha SDK, I’ve been working between my other duties on getting it running on the BeagleBoard. The Maemo on BeagleBoard project site has today been updated to include instructions for anyone to do the same.

The alpha SDK has released some content in the form of closed binaries. You are required to accept an EULA to gain access to the closed content and that means a ready-made rootfilesystem cannot be offered as a part of this project.

Instead a full set of instructions on how to build your own rootfilesystem using the Scratchbox1 based SDK is provided. The kernel image and modules are available for download and the kernel build process is documented. I’m not entirely happy with not providing a ready-made rootfs, but the closed binaries prohibit me from doing so. I hope you can understand this.

The provided kernel is buildable from the Maemo 5 alpha kernel sources (2.6.28) plus a sizeable patch which reimplements the display subsystem for BeagleBoard. The dss2 patches originate from the Ångström distribution‘s efforts available in the OpenEmbedded git, but within this project they are provided as one file.

The project’s default kernel configuration includes modules for USB HID, USB ethernet devices and USB mass storage devices. This means that you can use a mouse,  a keyboard, a USB-Ethernet plug or even a USB hard disk with your Maemo powered BeagleBoard — if you also have a powered USB hub, that is.

I was able to install packages from the Fremantle extras-devel repository directly to the BeagleBoard using apt-get. Someone had already uploaded a fun puzzle game Hex-a-Hop and it runs perfectly on this setup 🙂

Cheers,

FOSDEM 2009

Brussels was foggy and cold, not much warmer than Helsinki at this time of the year. Luckily the tightly packed ULB campus provided plenty of interesting talks and lectures on open source projects in the form of FOSDEM 2009.

Maemo on BeagleBoard

I gave a speech in the Embedded track announcing a newly started project “Maemo on BeagleBoard“, whose idea is to run Maemo software on a BeagleBoard. The project is just taking its baby steps and requires a lot of work to grow up to something really useful.

My slides for the speech can be found from the docs section of:

http://garage.maemo.org/projects/maemo-beagle/

The project infrastructure has been established and for the time being it just provides instructions how to set up your BeagleBoard to run Maemo stuff using the provided rootfilesystem and kernel image. The current release is based on the Maemo 5 pre-alpha2 SDK, which allows only a very spartan environment because of yet unpublished major Maemo 5 components.

I have high hopes that the upcoming alpha release of the Maemo 5 SDK will have more useful content available. Among other goodies, it will give us a first look at what the new Maemo UI will look like and if everything goes as planned you’ll be able to run the new UI on a BeagleBoard.

Why BeagleBoard?

BeagleBoard is a promising platform to run the new Maemo 5 software since it is built around an OMAP3 processor from Texas Instruments. Maemo 5 supports it too and all the software in the Maemo 5 repository is built with options suitable for OMAP3’s ARM Cortex-A8 core.

With all the fuss about BeagleBoard, you should keep in mind that in the end it is not an official target hardware for Maemo 5. It’s just something that’s low-cost, fun to hack with and processor-wise related to Maemo 5.

More information about the BeagleBoard can be found in:

http://www.beagleboard.org/

What next?

As mentioned, I’m putting high hopes on the Maemo 5 alpha SDK release to boost this project further. There’s a lot to improve on the web site and a good action plan is needed to see how to change the packages published in the SDK to better server the BeagleBoard environment.

Cheers,

Juha
