Well, with AVR32 I have better debug capabilities (the IDE doesn't
crash as much), and I was able to breakpoint at diferent levels of the
EMAC driver, TCP stack and user code. Also, given that apparently UDP
is working properly, I'm much more suspicious of the upper stack than
the hardware specific drivers.

Btw, I don't see hangs as Ulrich said. But I think r3170 could cause
hangs in 32 bits platforms as it doesn't care for alignment issues.
Also, I can't wrap my mind around the need of that change.

I have an ethernut1 based board here at hand, I will try to load httpd
example into it.

Kind Regards,
