Help with embedded code linking

[Grzesiek Gajoch]

Thanks for reply,
faster programmer is not a option - programming is done via WiFi (it
has to be done that way).
Yes, that's what I want to do - but the question is how to tell the
linker about libraries (which are already somewhere in memory)?
Pozdrawiam,
