Anjuta Plugin for OpenEmbedded SDK June 18, 2009

I have always liked the idea to have an Anjuta plugin that simplifies the use of cross toolchains in order to develop for all sorts of mobile and embedded devices. Personally I do not rely on an IDE but I have worked with a lot of developers in the past who are not used to do application development with vi. The same applies to cross toolchains, but there are reasons why people compile natively or why tools like Scratchbox are developed.

Some time ago OpenedHand published an Anjuta plugin for Poky that almost fits these needs – apart from minor lacks and the fact that you can’t use it with an OpenEmbedded build tree because it relies on the Poky directory layout. It didn’t take me long to modify the Poky plugin to fit the needs for OpenEmbedded: I have added automatic detection of the toolchain host prefix and some functionality to deal with the (not 100% fixed) directory layout of OpenEmbedded. So what does it do?

  • Select a toolchain or OpenEmbedded build directory to use
  • Configure and build a project
  • Deploying of binaries to a target device using rsync and ssh
  • Some debug and remote device features from the original plugin I didn’t test so far

It is easy to install (and build if necessary). I have created an initial website for it at KC Labs. You can find both source archive and binary packages for Ubuntu (9.04) and Debian Lenny. Once you have it installed it you should be able to design your GUI, fill it with functionality and deploy the application to a target device withouth leaving Anjuta.

Feedback is very welcome – if you have ideas about new features or what you would like to see for cross development please let me know!

Have a nice time…

PS: LinuxTag is approaching – visit the Embeded Area with projects like OpenEmbedded and Coreboot!

LinuxTag, GSoC and some progress… June 3, 2009

Its time to make announcements… I should have done this earlier, but like always it takes me a while to find a free minute to write things down.

First is about OpenEmbedded: We will be present at LinuxTag from 24th to 27th of June in Berlin/Germany. I just hope they have a little bit more space for us at the Embedded Area compared to last year. We usually have a lot of interesting devices running OE built Linux we can show. I’m really looking forward to LinuxTag – I haven’t missed one for many years and its always a nice event with a good mixture of community members, business people and users.

Google Summer of Code is in progress for some weeks now and I’m in the great position to mentor a very interesting Maemo project… something I always wanted to see but noone found time to do it properly so far: Integrate the Maemo software framework into OpenEmbedded. The benefits are quite obvious – Maemo software will gain compatibility and quality by running on (and if necessary adapting to) various devices. Apart from the fact that Maemo is a pretty good open source framework attracting quite a lot of developers. This is something other devices can and should gain advantage from. Well rkirti made a pretty good description of the project which can be found here.

It would be pretty cool to see Maemo running on this nice device I received a few days ago…

Its a FriendlyARM Micro2440 from Watterott Electronic – this one is equipped with the 7 inch display which gives some more “freedom” to the applications :-) Apart from this the hardware is the same I described in my previous post.

The screen geometry would match the one used by all Maemo devices so far, so it would not mess up all the graphical user interfaces. But there is still some work to do till the boards become a really good development platform. We can build useful filesystem images for them but the installation is still split up into too many steps and the up to date kernels still lack proper support for the camera and the wifi module.

I have made a toolchain to build software for both these devices and the Topas910. Together with an updated install instruction it can be found here at labs.kernelconcepts.de.  Now I’m investigating ways to integrate the toolchains with IDEs in order to simplify application development for mobile and embedded devices.

Here the device runs one of the Ultimate++ demo applications built with its IDE and the GPE-flavour cross toolchain built with OpenEmbedded. A friendly colleague found out what needs to be done to use it for ARM targets… it still needs a little help since Ultimate++ doesn’t seem to have an idea about pkgconfig and I’m not really happy with the size of the resulting binaries. But more about IDEs later…

Have a good time… and see you in Berlin!
