FreeBSD on ARM devices

April 19, 2012 — 1 Comment

Damjan Marion published nice how-to for getting FreeBSD running on BeagleBone. Using it I managed to get my PandaBoard ES running off SD card. The only modifications to this instructions are:

  • Use PANDABOARD kernel config. Stock version is configured to use NFS so it should be modified to use SD card as root.
  • MLO and u-boot.bin binaries are different. I used these. You’ll need boot.scr too.

Performance is still affected by using write-through caches by default, but this issue should be fixed soon.

boot log:

Welcome to FreeBSD!

Before seeking technical support, please use the following resources:

o  Security advisories and updated errata information for all releases are
   at http://www.FreeBSD.org/releases/ - always consult the ERRATA section
   for your release first as it's updated frequently.

o  The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
   along with the mailing lists, can be searched by going to
   http://www.FreeBSD.org/search/.  If the doc package has been installed
   (or fetched via pkg_add -r lang-freebsd-doc, where lang is the
   2-letter language code, e.g. en), they are also available formatted
   in /usr/local/share/doc/freebsd.

If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the questions@FreeBSD.org mailing list.  If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
manual page.  If you are not familiar with manual pages, type `man man'.
