Sounds good - if the demo worked as quickly as it seems to have, your 
porting effort should be quite small!

This is funny - I have omitted one important step from the instructions 
- how to enable the ethernet driver!!

Look at the bootup log, there's no mention of the driver initialising, 
meaning that the eth0 device isn't there.  The strange "%m" messages are 
from a flaw in the uClibc config that is in the older uClinux-dist, it's 
fixed in the new one.

So, to fix your problem, go into menuconfig -> kernel config -> 
processor type and features, and enable the ethernet driver.  Save and 
exit, make dep, make etc, and try again.

Sorry for the ommission, I'll correct the page right now...

Cheers,

John
