I finally managed to cross compile all - thanks for all infos and help!

However, to save time, I would like to boot 'diskless' or provide an md-image.
Neither of them I got to work ...

I can boot with USB-Disk (/usr via NFS)
I can't setup a memory disk in a bootable kernel
I can't boot a kernel with root on NFS

1. how to setup memory disk:
  how do I get 'netbsd-sd0.bin' from 'netbsd-sd0'  + md-image for 
  loading with RedBoot without doing a 'distribution'?
  ( /usr/src/distrib/evbarm  ?)

Here is what mdsetimage says:
epia1(root) OLIMEX_EP9301_INSTALL> mdsetimage -vx netbsd-epe0 
got symbols from netbsd-epe0
mapped netbsd-epe0
copying image netbsd-epe0-IMAGE from netbsd-epe0
done copying image

epia1(root) OLIMEX_EP9301_INSTALL> mdsetimage -vx netbsd-epe0.bin  
check format: File format not recognized

... so I didn't even try to set an md-image

2. bootp / dhcp does not work
  I simply get "nfs_boot: timeout..."
  Server doesn't get any request
  (BTW: dhclient also doesn't work from the Olimex provided 3.0 NetBSD,
  and my dhcp-server is verified to work!)

  The 'diskless' Documents are not very expressive about sepcifics for the
  Things work, when using an USB-disk and NFS-mount /usr ... but that's what
  I would like to avoid

Kernel Config:
config      netbsd-epe0 root on epe0 type nfs
epe0        at epsoc? addr 0x80010000 size 0x10000 intr 39
options     NFS_BOOT_BOOTP
options     NFS_BOOT_DHCP

Here is a boot-log, trying DHCP:

One more question:
during boot, I can see 'epgpio0' and 'gpio' but in /dev I only see 'gpio' ...
similar with 'eprtc', 'epwdog'
what am I missing?

Thanks for help!
