Fw: stuck in bringing the userland shell on a latest ARM core

[newbie <mailto635%yahoo.com@localhost>]

Hi All,

I am trying to bring up NetBSD-5 on a latest ARM Core (which is not yet 
natively supported by NetBSD/arm port) as part of learning NetBSD. 

I do not have any previous practical exposure on NetBSD or for that matter on 
any other Unix-like OSes.

I am able to bring up the kernel in a couple of weeks (although not in a clean 
way), but I am stuck in brining up the userland.

First I ran into nbmakefs toolset problem in building the ramdisk under cygwin 
development environment. Then I bumped into version mismatch between the 
userland and kernel.

With the right ramdisk matching kernel version(got from Mr.Ken Hornstein), My 
serial console output is as below:
