Hi Hans,

Thanks for the tip on the login in for the FTP server, yes that was an
issue on my part.  In another email I detail out what I've done in
regards to .config and I have a kernel based on 2.6.23.atmel.4 that I
can run but still cannot debug.

I won't say much here, I'll save it for another email in progress,
trying to minimize the bulk here :)

Thanks again,
Dave

Root login is not allowed over FTP, due to ProFTPD default 
configuration. Did you try login with "avr32"/"avr32!", without the ""? 
Your previous email did not have a ! on the end of the password.

Perhaps the locking debugging is turned on by default? It consumes a lot

of memory, even running with 16 MB SDRAM is a bit short. Check what is 
enabled under kernel debugging.

I am able to ftp to NGW100/STK1002 running with Buildroot v2.1.0 default

images. User "avr32" and password "avr32!". What ftp client are you 
using to connect?

The default image should be sane. I think this may be related to either 
wrong password and/or a kernel demanding too much RAM to run.
