[Buildroot] Buildroot for powerpc, no prompt + OpenSSH login

Thu Jan 21 15:49:10 UTC 2010

Oops...
My bad ! I checked "generic serial port config", but forgot to select 
"ttyUL0" ;-P...
Thank you for your help.

Anyway, my second problem still doesn't work, can you help me with that?
I re-explain here:

When I try the to connect to the OpenSSH of my card, it does ask me for a 
password.
But root user doesn't have a password, I can login without it.

How to do? Should I connect with a different user? Is there a default 
password for SSH?

Thank you.
