Build a Raspberry Pi 2 Minimal Image with The Yocto Project

The Yocto Project is a build system that allows developers to make custom Linux distributions matching their exact needs. I’ve already shown how to build a 12MB Compressed image for the Raspberry Pi with Yocto, but the Raspberry Pi 2 has recently been added to the project, so I’ve tried to build it too in a machine running Ubuntu 14.04. I’ll use poky since it’s the default, but you could also build the system for Angstrom or without distributions (OpenEmbedded Core only). The steps to get the code is just the same as for the Raspberry Pi:

mkdir yocto
cd yocto
git clone git://git.yoctoproject.org/poky.git
cd poky
git clone git://git.yoctoproject.org/meta-raspberrypi

mkdir yocto

cd yocto

git clone git://git.yoctoproject.org/poky.git

cd poky

git clone git://git.yoctoproject.org/meta-raspberrypi

You just need to checkout master, and not any branch (like dizzy) since R-Pi 2 is not yet supported in any release. Initialize some environment variables and the build directory:

. oe-init-build-env build

1	. oe-init-build-env build

Now edit conf/local.conf with vim or nano to set the machine to raspberrypi2 instead of qemux86:

MACHINE ??= "raspberrypi2"
GPU_MEM = "16"

1 2	MACHINE ??= "raspberrypi2" GPU_MEM = "16"

There are more Raspberry […]

Embedded Linux Conference 2015 Schedule – IoT, Cars, and Drones

Embedded Linux Conference 2015 will take place in San Jose, California, on March 23 – 25, 2015, and will focus on Drones, Things and Automobiles. The schedule has been published, and whether you’ll attend or not, it’s always interested to have a look at what will be talked about to have a peak into the future of Embedded Linux, or simply keep abreast with the progress in the field. So as usual, I’ve gone through the schedule, and made my own virtual program with talks that I find interesting. Monday 23rd 9:00 – 9:30 – Driving standards and Open Source to Grow the Internet of Things by Mark Skarpness, Director of Systems Engineering at Intel Billions of devices are beginning to come online, and many of these devices, large and small, are running open source software. To fuel this innovation, it’s more important than ever for these devices to use […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]
