  I don't have particular experience with IQ80321, but redboot should
work in the same way.

  If you download the binary over serial line, type

   RedBoot> load -m x -r -b 0xa0200000

then, start xmodem to transmit kernel binary. and type

   RedBoot> go 0xa0200000

to start NetBSD.

You can download gzipped binary for speed with -d option.

Also, you can download via TFTP if your redboot supports network.

   RedBoot> load -m tftp -r -b 0xa0200000 -d netbsd.bin.gz

You need to setup DHCP or BOOTP server and TFTP server for this to work.
Please refer to http://www.netbsd.org/Documentation/network/netboot/

For redboot's commands, see
http://sources.redhat.com/ecos/docs-latest/redboot/redboot.html

I hope this helps.

acorn 4000/2mb ram

ey i should have sent this to port-arm26, but seeing as thats an 'invalid'
mailing list, i thought i should send it here.
the last time i looked at netbsd/acorn26, it was still arm26 - and i
wondered if the functionality for 4mb machines
had been completed.

would there ever be a 2mb port?
;p

logik.

Not really.  I believe people have managed to get a useful single-user
shell, but it took a fair amount of work.

It's not quite as big a step as you might expect, since a 2 MB machine
will have smaller pages.  It's still very unlikely.

are any of the netbsd users in australia able to sell me 4 x 512k dip style
ram chips?
and also - what is the maximum throughput of the rockwell 6551 acia chip?

I think its baud rate can go up to 19200, but I haven't got the data sheet
to hand right now.

The predecessor iq80310, and I presume the 321 is no different here, 
supports BOOTP style
booting. A more manual way would be to use the Redboot load command, 
with the
TFTP option.

In either case, you need to have a NFS server with the root hierarchy 
setup on some machine.
I have a NetBSD-x86 machine setup to act as the NFS server. My DHCP 
server points the
booting machine to this NFS server.

The Redboot command for loading is something on the order of:

load -r -b 0xa0200000 -m TFTP netbsd-nfs

Then:

go 0xa0200000

(You need to check to see what the exact name of the binary is and place
that in the tftpboot directory.)

My A3020 will never feel the same again :)

Seriously though, a 4 MB acorn26 machine is not fast. Mine took 45 minutes
to boot to a login prompt. OK that was with root and swap on NFS, but
still.

Man, that would be painful.

Now that I've got the data sheet in my hand, I think I can answer that.

The maximum clock rate specified for both receiver and transmitter is
2.5 MHz.  This gives a data rate of 156250 bit/s.

If you're only interested in the chip as installed in the Archimedes, then
you're stuck with the standard 1.8432 MHz crystal, which gets you
115200 bit/s.

Of course, I've not actually tested any of this.
