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.
Wann immer es erforderlich ist, ein embedded Gerät einfach so ohne Vorbereitung ausschalten zu können, kommt das Thema Dateisystem-Konsistenz auf. Werden Daten geschrieben und haben vor dem Ausschalten ihren Weg auf das Speichermedium noch nicht vollständig gefunden, droht deren Verlust.
The Arria10 SoCFPGA can boot from multiple sources: SD Card, NAND flash, QSPI flash and eMMC, that can be selected via the BSEL pins. If the bootrom can not find a valid bootloader on that medium, it will fall back to JTAG. So for developing and testing, the BSEL pins can just be set to a medium that is non-existent. In case of bootstrapping, the bootrom falls back to JTAG anyway, as there is no valid bootloader, yet.
A BSP (Board Support Package) in Embedded Software is the layer of software that lets you run your application on a specific hardware. For Pengutronix a BSP usually contains a bootloader, Linux Kernel and a userspace. DistroKit is our Demo-BSP that supports a variety of common evaluation boards. DistroKit gives you a head start if you want to develop an application on top of such an evaluation board with most of the hard problems already solved.
An einem weit entfernten Ort, fernab vom Tagesgeschäft, haben sich die Mitarbeiter von Pengutronix zur jährlichen Technologiewoche getroffen.
Just before the beautiful shine of the new has fully disappeared from RAUC 1.0, it is now time to bring out a new release: v1.1.
