foss-north 2017: Call for Papers

The Call for Papers for foss-north is open for another week (until the 12th). This gives you an opportunity to speak in front of a great crowd. Looking at the results from last year’s questionnaire, more than 90% are users of open source software and more than 50% are contributors. One thing that surprised me, is […]

The topics are Yocto Linux on FPGA-based hardware, risk and license management in open source projects and a […]

Vacation 2015

So, vacation has finally arrived in 2015. To the despair of some, and joy of others, the Swedish standard vacation is 3-5 weeks over the summer. I’ll be having five weeks of this year. So, what do you do with five weeks? Generally, I start out ambitious and end up in reality after 3-4 weeks […]

meta-kf5 usable

Finally I’ve had the time to work over the final issues in meta-kf5. Right now, I build most tier 1 and tier 2 components. I’ve packaged most functional modules and integration modules from these tiers. When it comes to integration modules, there might be missing dependencies that need to be added – but that should […]

meta-kf5 – almost there…

So, as of tonight, all but three tier 1 modules from kf5 are built in meta-kf5. The ones remaining are KApiDox, which does not really apply, and KConfig and Sonnet, which both needs to be part built for the native host environment, and part cross compiled. So, any Yocto hackers out there, please have a […]

meta-kf5 progress report

The meta-kf5 Yocto  layer is coming along nicely. Most of the modules are proving to be fairly easy to integrate, much thanks to the excellent ground work in meta-qt5, including the cmake_qt5 bbclass. My plan for the summer vacation was to do one module a day, so around 5 would be ok. Until now I’ve […]

KF5 in Yocto

KDE recently released the first version of KDE Frameworks 5, or shorter KF5. This is a set of add on modules extending and improving Qt, forming the base on which the Plasma Desktop is built. The nice thing is that KF5 is very modular and very reuseable. Recently I’ve spent some time working with Yocto (yes, […]

Yocto part IV – going on a diet

This time we will start looking at how we can reduce the image size of the diet-image. Before we start, lets do a super-quick recap of the first three installments (i, ii, iii): Start by creating and populating a project area: mkdir minimal cd minimal/ git clone git://git.yoctoproject.org/poky cd poky/ git checkout -b daisy origin/daisy […]

Yocto part III – a custom meta layer

In this part of the series (previous: i, ii) we will have a look at setting up our own meta layer, so that we can make changes without having to fork the Yocto recipes. The easiest way to create a layer is to use the yocto-layer tool. To fully understand what a layer consists of, […]

Yocto part II – baseline image size

In the first installment of this series, we established a base line image and had a look at the initial boot performance. This time, we will establish a baseline for the image size. In an embedded system, these two factors often go hand in hand, as reading data from FLASH often consumes a considerable amount […]
