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.

Next steps

Implement console driver over uart.

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)
