Running NetBSD in Qemu-neo1973

A NetBSD port is only ready for kernel developers.

Required tools

You will need Qemu-neo1973.

Hints on building it are avaliable from OpenMoko under QEMU on NetBSD/i386.

The package itself is avaliable in under qemu-neo1973.

Building NetBSD

You will need mkimage from u-boot. It's available in under u-boot.

You'll need to download some kernel files.

In [download-area]

pick Attachment: "NetBSD/evbarm 3.1 NEO1973 syssrc 20071010"

Save Link As... syssrc-neo1973-20071010.tar.gz

and extract it over the NetBSD src tree.

tar xfz syssrc-neo1973-20071010.tar.gz -C /

From the NetBSD src tree run:

cd /usr/src
./ -m evbarm tools
./ -u -m evbarm kernel=NEO1973
mkimage -A arm -O netbsd -T kernel -C none -a 30008000 -e 30008110 -n "Kernel Image" -d /usr/obj/sys/arch/evbarm/compile/NEO1973/netbsd  /usr/obj/sys/arch/evbarm/compile/NEO1973/netbsd.boot

You'll now have a copy of the NetBSD kernel, called netbsd.boot, that's able to be loaded by u-boot.

Prebuild NetBSD

You'll need to download a kernel.

In [download-area]

pick Attachment: "NetBSD/evbarm 3.1 NEO1973 kernel 20071010"

Save Link As... netbsd-NEO1973-20071010.gz

extract and move this kernel into place:

gzip -d netbsd-NEO1973-20071010.gz
mv netbsd-NEO1973-2007101 /usr/obj/sys/arch/evbarm/compile/NEO1973/netbsd.boot

Running NetBSD

From the qemu directory edit the openmoko/ and add the line:


after the four "most_recent" lines.

(if you do use wip/qemu-neo1973, the line is allready there..and you should only have to uncomment the line.)

Next run


This will fetch the required parts and create an image to run. They require you to have bash installed.

Finally run qemu with

cd /usr/pkg/emul/neo1973; qemu-system-arm -M neo -m 130 -mtdblock openmoko/openmoko-flash.image -kernel openmoko/openmoko-kernel.bin -usb -show-cursor -serial telnet:localhost:1200,server

And from another xterm

telnet localhost 1200

and qemu will go on with the startup process.

In Qemu running u-boot,

press Space to select option "Boot".

In telnet to the serial port you should see:

host007# telnet localhost 1200
Connected to localhost.
Escape character is '^]'.
