Interested in using FreeBSD on the Neo1973 or as a Host OS? Get in touch with mn -at- bsdgroup.de and andrew -at- fubar.geek.nz, they are currently exploring what to do about this.

Running FreeBSD in Qemu-neo1973
A FreeBSD port is only ready for kernel developers.
Required tools
You will need mkimage from u-boot. It's available in Ports under devel/u-boot.
You will also need Qemu-neo1973. Hints on building it are avaliable from this page.
Building FreeBSD
You will need to download http://fubar.geek.nz/files/freebsd/neo1973/neo1973-0.20070917.tar.bz2 and extract it over the FreeBSD src tree.
From the FreeBSD src tree run:
make buildworld TARGET=arm TARGET_ARCH=arm TARGET_CPUTYPE=arm920t
make buildkernel TARGET=arm TARGET_ARCH=arm TARGET_CPUTYPE=arm920t KERNCONF=NEO1973
gzip -9 usr/obj/path/to/kernel
/path/to/mkimage -A arm -O freebsd -T kernel -C gzip -a 30008000 -e 30008000 -n "Kernel Image" -d /usr/obj/path/to/kernel.gz /usr/obj/same/path/kernel.boot
You will now have a copy of FreeBSD that is able to be loaded by u-boot.
Running FreeBSD
From the qemu directory edit the openmoko/flash.sh and add the line
kernel_image="/usr/obj/path/to/kernel.boot"
after the four "most_recent" lines.
Next run
./openmoko/download.sh
./openmoko/flash.sh
This will fetch the required parts and create an image to run. They require you to have bash installed.
Finally run qemu with
arm-softmmu/qemu-system-arm -M neo -m 130 -mtdblock openmoko/openmoko-flash.image -kernel openmoko/openmoko-kernel.bin -usb -show-cursor
It will display "Kernel loading..." with no further messages.
You can append
-serial telnet:localhost:1200,server
to the qemu startup line to start a telnet server which represents the serial console, just
telnet localhost 1200
and qemu will go on with the startup process.
