It is possible to create a component (ex. UART) with avalon MM slave interface with 8 bit data width and use it with Nios II with 32 bit bus? I tried and compile fine but Nios II don't start on re...

Try using signaltap to look at a real nios rather than using the simulator, or at least run the gate-level simulator talking to avalon slaves.
