I am a newbie here and do not know much. But if I were you, I would search CW for source code of
"startup" or "CRT0". I would also disassmble the code pointed by the reset vector with debugger.

Hello

First of all, which development tool chain are you using (CodeWarrior, .....)?

Startup code is vendor specific. It is completely different depending on the compiler vender you are using.
