I bought SheevaPlug in the hope of running a nice low power server for
personal needs, so it is my 1st exposure to ARM device.
I use FreeBSD on Intel machine, but arm is Tier2 support, so I decided to
give NetBSD a try. Unfortunately I am completely confused by the
installation procedure. The instructions are focused on TFTP server, but I
am trying to use USB stick formatted with FAT 16.
I am just trying to boot into NetBSD without installing it on SDHC card.
I don't know if it is the best way to go.
I don't know which file I need to copy onto FAT16, so I copied 2 files:
gzcat /Volumes/NETBSD_614/EVBARM/BINARY/KERNEL/NETBSD_IQ80321.BIN_GZ >
NETBSD_IQ80321.BIN
gzcat /Volumes/NETBSD_614/EVBARM/BINARY/KERNEL/NETBSD_IQ80321.GZ >
NETBSD_IQ80321
I then tried loading both files and failed.
On Boot:

Wrong Image Format for bootm command
ERROR: can't get kernel image!
The autoload errors are coming from missing SDHC card with Debian Linux on
it.
I then try loading what I think kernel files are and the system hangs. I am
sure I just don't do it right.
Marvell>> fatls usb 0

Marvell>> go 0x900000
## Starting application at 0x00900000 ...
And that's when it hangs. I see nothing, so I pull the plug and try again.
The installation document references memory 0x60660000. If that's the case,
then I don't know which memory address to load into. I use 0x900000,
because it works with Linux kernel, which is probably not right.
Several months ago I compiled custom FreeBSD image, and was able to boot it
(don't remember much about it). Unfortunately, I found that I could not
boot FreeBSD from SDHC and abandoned that route. I hope NetBSD is better in
that respect.
thank you
