With noMMU Architecture, fork() is not available. You need to use vfork() instead. AFAIK, in MMU-Linux vfork() usually is mapped to fork(), so you can just always use vfork() unless you need some specifics of fork that vfork does not provide.

I don't know what you mean by "start two applications". But one application can use (v)fork() and friends to start another application, either using it's own code (thus working similar as a multi-thredded application) or load new code from a file.
