Hi Ulrich,

For Ethernet I prefer to have a bit more RAM. On my AT90CAN128 design 
with 32K I ended up always a bit short of RAM which is needed for thread 
stack to have TCP connection endpoints.

I have not used an ARM CPU before, so how does the RAM consumption for 
stack and general Nut/OS use compare to an AVR? I assume it is more just 
because of the 32-bit architecture but what sort of factor would you 
apply? I am just after a rough number like 30% or 50% more?
