Right before the ELC-E starts tomorrow, we used the time in the hotel to bake a brand new RAUC release for you (and your embedded devices)! Well, here it is: RAUC v1.2
Tomorrow, Embedded Linux Conference Europe 2019 starts in Lyon, france, and as every year, Pengutronix crew uses this opportunity to present our recent open source activities and to meet other Linux and OSS developers. Here's the list of our talks during the next days:
Has this ever happened to you?
In this blog post I would like to address the challenges of performing unattended and verified updates of embedded Linux systems in the field using open source software and workflows. While updating is not a end in itself, a second part of my considerations goes even further and also works out the necessities and possible workflows for keeping the software stack of a project up to date and thus either preventing security issues or at least enabling a short reaction time in case of severe CVE'S discovered.
Today it has been 15 years since we mainlined support for Freescale/NXP's i.MX architecture in the Linux kernel! That was one small step for [a] man, one giant leap for (industrial Linux users') mankind :-) Here is some background about why it happened and what you might want to learn from history for your next embedded Linux project.
Pengutronix has been to FrOSCon at the University of Applied Sciences Bonn-Rhein-Sieg. This year we had a booth where we presented our Open Source activities and were able to contribute three talks. A booth at an Open Source conference like FrOSCon always opens doors to a lot of interesting conversations with new faces, old friends and colleagues.
Whenever it is a requirement to be able to switch off an embedded device without any previous preparation, the next question is about the consistence of the used filesystem. If this filesystem is used to be written with new content and this new/changed data hasn't done it's way to the persistent media when the power is cut, this new/changed data is lost.
