Barebox-2014.02.0

Jürgen Borleis | | barebox

Die Version 2014.02.0 des Barebox Bootloaders wurde veröffentlicht:

Neue oder geupdatete Features sind:

  • Viele Bugfixes und Verbesserungen
  • Support für die OpenCores 10/100 Mbps Ethernet MACs
  • Die IPU Framebuffer Treiber (i.MX35) wurden verbessert und supporten nun die Bereichnung der Clocks mit verringertem Jitter. Damit ist es nun möglich, externe LVDS Displays zu betreiben.
  • Das Memory Management wurde geändert und Barebox findet nun automatisch Speicherstellen, um ATAGs für die Kernel-Parameter zu übergeben. Alle Plattformen wurden auf das neue Verfahren umgestellt, so dass der Plattform-Code weniger Platz einnimmt.

Foster mvebu Support in barebox

Uwe Kleine-König | | barebox

barebox works great on NXP's i.MX platforms. While there is some support for Marvell's mvebu platform, it is not even near being complete. The main limitation is in my eyes that there is no code to initialize RAM settings on these machines.


Bootstrapping Arria10 with OpenOCD and barebox

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.


Porting Barebox to the Digi CC-IMX6UL SBC Pro

Rouven Czerwinski | | Barebox

One of our projects required the addition of board support for the Digi ConnectCore 6UL SBC Pro to the Barebox bootloader. This article outlines the used development setup and required additions to the bootloader to support a board with a well supported processor. Development of the board support was done live during the monthly talks at Stratum 0, the hackerspace in Braunschweig. The video (in German) is embedded at the end of the article.
