So you probably need to add the flash package.

No, not without you giving us the details...

I've never used these tools, so it is hard to say. What libraries do
you need? How dependent are these on having true BSD sockets? The lwip
stack has something like BSD sockets, but it is not true BSD
sockets. You might run into problems when porting the RPC libraries
etc.
