The correct way to do this should be:
ecosconfig new at91sam7xek lwip_eth
However, the resulting tree then fails to build. There was a fix to
realloc a while ago which changed a memcpy to a memmove and how there
are undefined symbols. I need to look at this and work out why.
ecosconfig new at91sam7xek lwip_eth
ecosconfig add libc_string
ecosconfig tree
should work.
Andrew
Actually the building packages include packages begin with "ISO ..." , so
the libc_string package is ready in the building packages and the conflicts
are just the same as before.

BTW: How much memory will the lwip stack take? The at91sam7x256 has only 64k
ram and I don't know whether it's suitable for some internet applications.
Maybe I will get another arm board to develop the product. Any suggestion is
welcome, thanks!
