IPv6 works just the same as IPv4 in terms of
routing. fe80::201:2ff:fe37:2ea0 is not on any of the directly
connected nets. So it has to be routed through a
gateway. Unforutately, you don't have any routes to gateways
configured and not default route. Hence it does not know where to send
the packet and so it is printing the error message. 

You need to sort out your IP addresses and routers and make sure eCos
knows this information. Probably the easiest way to do this is use
radvd or some other router advertisement program.
