"Address Space Overflow" This error information appear in the uVision2, but I cann't determine the error source!
You've used up too much memory of some type. 128 bytes of data space, N KB of xdata space depending on your variant, and so on. It's possible you have some unresolved external references (typos in function names, functions you didn't write) as well. Post the complete text of the error message(s) and people could make better suggestions.
