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.
A FreeBSD port is only ready for kernel developers.
You will need:
To build Qemu on FreeBSD to test and develop FreeBSD on the Neo's:
You will need to download http://fubar.geek.nz/files/freebsd/neo1973/neo-20080629.tar.bz2 to build FreeBSD for the Neo1973.
From the FreeBSD src tree run:
make buildworld TARGET=arm TARGET_ARCH=arm TARGET_CPUTYPE=arm920t make installworld TARGET=arm TARGET_ARCH=arm TARGET_CPUTYPE=arm920t DESTDIR=/path/to/root/fs
You will now need to trim down /path/to/root to remove things noot needed to test in single user mode
makefs -B little /path/to/root.ufs /path/to/root/fs make buildkernel TARGET=arm TARGET_ARCH=arm TARGET_CPUTYPE=arm920t KERNCONF=NEO1973 -DNO_MODULES MFS_IMAGE=/path/to/root.ufs mkimage -A arm -O freebsd -T kernel -C none -a 30008000 -e 30008110 -n "Kernel Image" -d /usr/obj/path/to/kernel /usr/obj/same/path/kernel.boot
You will now have a copy of FreeBSD that is able to be loaded by u-boot.
From the qemu directory 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 gta01 -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.
Another method of getting the kernel into the neo is to use an image for the emulated sd card. I already have a file called sd.img ( dd'ed from a 32mb usb stick).
cp /usr/obj/arm/usr/src/sys/NEO1973/kernel . /usr/obj/arm/usr/src/tmp/usr/bin/objcopy -O binary kernel sudo mdconfig -a -t vnode -f sd.img sudo mount_msdosfs /dev/md0s1 /mnt/tmp sudo cp kernel /mnt/tmp/ sudo umount /mnt/tmp sudo mdconfig -d -u 0 arm-softmmu/qemu-system-arm -M neo -m 130 -mtdblock openmoko/openmoko-flash.image -kernel openmoko/openmoko-kernel.bin -sd sd.img -usb -show-cursor -serial telnet:localhost:1200,server
In another terminal:
telnet localhost 1200 mmcinit fatload mmc 0 0x30008000 kernel go 0x30008000
And wait for the crash :)
