The lwip part does send and receive PPP packets, but not establish a 
connection.

Since file access is problematic on my target, I had disabled tcpdump.
But I'm sure there were no IP packets on the line.
I had a sniffer at the serial port and saw only PPP negotiation attempts 
from both sides.

I'll post a message log later. Please note that I have both SLIP and 
ethernet working, this is a PPP only problem.

Do I gather correctly, that nobody can report PPP success on a 
big-endian target so far?
