FreeBSD 9.2p1 image for Soekris

Building a FreeBSD kernel for Beaglebone is not terribly difficult.  Firstly, you need the FreeBSD-Current sources: svn co http://svn0.us-east.freebsd.org/base/head /src/FreeBSD/ Next, build the cross-development tools for FreeBSD: cd /src/FreeBSD/head make XDEV=arm XDEV_ARCH=armv6 xdev Then get Crochet-FreeBSD.  This is by far the easiest way to build a FreeBSD kernel for Beaglebone git clone git://github.com/kientzle/crochet-freebsd.git Once you…

I often have a need for a fresh FreeBSD install, to host a server, or perhaps just experiment with. My usual solution is FreeBSD jails. However, I’ve recently gotten interested in Ansible and AWS. There are quite a few advantages to installing infra with AWS, however the one I’m most interested in is automating the…

I’ve updated the u-boot bootloader for Crochet-FreeBSD Wandboard to 2014-10, from 2014-07.  The updated image is here, and the boot log is here.  

The default FreeBSD kernel for Raspberry Pi can be found here in the FreeBSD source browser.  It’s everything you need to boot FreeBSD on a Pi, and includes GPIO support.  However, the Pi is a nice small computer, so it’s likely that you’ll want it to include options such as Wifi, and pf.  In my…

I’m upgrading the U-boot version used for Wandboard by Crochet-BSD.    The first step is to upgrade the Device Tree Compiler (DTC); there are instructions here. Once you have the U-boot 2014 source, the build is trivial: gmake SED=gsed HOSTCC=cc CROSS_COMPILE=armv6-freebsd- wandboard_quad_config gmake SED=gsed HOSTCC=cc CROSS_COMPILE=armv6-freebsd-  

How the FDT works In specific, I’m looking at this file bcm2835.dtsi which contains the hardware definitions for the BCM2835, the SOC which powers a Raspberry Pi. Primarily, i’m interested in how to read it.   To really make sense of this, you should have this pdf at hand; it’s the hardware manual for BCM2835.  If…
