Pidora 18 (Raspberry Pi Fedora Remix 18) Released

John Chiappetta, working for Seneca Centre for Development of Open Technology, has recently announced the release of Raspberry Pi Fedora Remix 18, which will be now known as Pidora 18. If you were there at the time of Raspberry Pi Fedora Remix 14 release, the first ever Linux distribution released for the Raspberry Pi, you may remember it had many issues, and the Raspberry Pi foundation decided to remove it from their Download page. This fourth release will hopefully fix many issues, and they’ll end up back on Raspberry Pi site. Based on the Changelog vs R-Pi Fedora Remix 17, Pidora 18 features look promising: Almost all of the Fedora 18 package set available via yum (thousands of packages were built from the official Fedora repository and made available online) Compiled specifically to take advantage of the hardware already built into the Raspberry Pi Graphical firstboot configuration (with additional modules […]

Final Release of Fedora 18 for AllWinner A10 & A13 Powered Devices

A few months ago, Hans de Goede, currently working at Red Hat and a Fedora contributor, started to show up on linux-sunxi mailing list, and sent a lot of kernel patches for linux-sunxi kernel. Last week-end, he announced “Fedora 18 Final for Allwinner A10 and A13 based devices” on linux-sunxi community mailing list. To install it, first download the image:

wget http://scotland.proximity.on.ca/contrib-images/hansg/Fedora-18-a10-armhfp-r1.img.xz

1	wget http://scotland.proximity.on.ca/contrib-images/hansg/Fedora-18-a10-armhfp-r1.img.xz

And write it to an SD card (all data will be wiped out):

xzcat Fedora-18-a10-armhfp-r1.img.xz &gt; /dev/mmcblk0

1	xzcat Fedora-18-a10-armhfp-r1.img.xz > /dev/mmcblk0

You may have to replace “/dev/mmcblk0” by your own SD card device, e.g. “/dev/sdc”. AllWinner based devices can share the same kernel, but u-boot is board/products specific, so you’ll have to install u-boot for your board. First remove the SD card, re-insert it in order to automatically mount the FAT partition, and run:

sh &lt;uboot-part-mount&gt;/select-board.sh

1	sh <uboot-part-mount>/select-board.sh

This will show the list of supported boards and products. Then run the command again for your device. For example:

sudo sh &lt;uboot-part-mount&gt;/select-board.sh mk802

1	sudo sh <uboot-part-mount>/select-board.sh mk802

A Selection of FOSDEM 2013 Events

FOSDEM is a 2-day (or 3 if you include Friday beer event) event where over 5,000 members of open source communities meet, share ideas and collaborate. It’s free to attend, and there’s no registration, so you just show up to attend. FOSDEM 2013 takes place on Feb 2-3 (yep, this week-end) in Brussels There are 7 main tracks where sessions are organized: Operating systems Open source challenges Security Janson Beyond operating systems Web development Miscellaneous Robotics There are also keynotes and devroom for a total of 488 sessions. Developers rooms that may particularly be of interest to readers of this blog are: Cross Desktop devroom – e.g. Wayland, gstreamer, razor-qt, Qt Project, Plasma Active, etc… Cross Distro devroom – e.g. Linux on Android, suse on ARM, ARMv8, systemd, etc… Embedded and mobile devroom – e.g. Baserock Embedded Linux, Guacamayo (Yocto), Nemo Mobile/ Mer project, arduino… All in all that’s a […]

The End of Embedded Linux (As We Know It) – ELCE 2012

Chris Simmonds, freelance consultant and trainer (2net ltd), discusses the future of embedded Linux now that storage and processing power are no longer an major issue, and try to find the best Linux platform for embedded systems at ELCE 2012. Abstract: Embedded Linux is at a cross roads where the combination of Moore’s law making devices more powerful and the mass production of consumer devices, especially mobile, making them cheaper means that the old ways no longer work. Only a few years ago we though in mega: MHz, MBytes, MBits/s. Now we have to think in giga. The days of the single core CPU are almost over, as are the days of the QVGA display. All this means that there is a need to re-think how embedded devices are programmed. Two obvious roads lie ahead: Android and Ubuntu (or other desktop operating system of your choice). This talk considers the […]
