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 a copy of mkimage from u-boot. To build it fetch a copy of u-boot, cd to the tools directory and build it manually:

cc -DUSE_HOSTCC -I../include -c ../lib_generic/crc32.c
cc -DUSE_HOSTCC -I../include -c mkimage.c
cc -DUSE_HOSTCC -o mkimage mkimage.o crc32.o 

If config.h is missing you can build one by using

gmake CC=/usr/bin/true gta01bv3_config

in the u-boot directory (you must have applied the patches for u-boot from openmoko)

You will also need a copy of 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 QT2410" -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.

It will display "Kernel loading..." with no further messages.
