Running NetBSD in Qemu-neo1973
A NetBSD port is only ready for kernel developers.
Required tools
You will need mkimage from u-boot. It's available in pkgsrc/wip under u-boot.
You will also need Qemu-neo1973. Hints on building it are avaliable from this page.
Building NetBSD
You will need to
cd /usr/src/sys/arch/evbarm/conf
cp SMDK2410 NEO1973
cp std.smdk2410 std.neo1973
and apply these patches

From the NetBSD src tree run:
cd /usr/src
./build.sh -m evbarm tools
./build.sh -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 will now have a copy of NetBSD that is able to be loaded by u-boot.
Running NetBSD
From the qemu directory edit the openmoko/flash.sh and add the line
kernel_image="/usr/obj/sys/arch/evbarm/compile/NEO1973/netbsd.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
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 Enter two times to opt "Set console to serial" press Space to select. press Space to select option "Boot"
in telnet to the serial port you'll see:
host007# telnet localhost 1200 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.
