Data width in the Avalon-MM Write FIFO in DSP Builder

Hi,

In my design in DSP Builder I am using the block Avalon-MM Write FIFO because I want to include it in a SOCP system. In the data width of the block I write 1 and in the FIFO Depth 16.

The simulation in Simulink run properly but when I build the nios II system in SOPC Builder I obtain an error with the data width in Avalon Bus

ERROR:

slave data width (1) for slave my_Scrambler/Avalon_MM_Write_Slave unexpected

Error: Generator program

for module 'cpu' did NOT run successfully.

The data width of Avalon Bus is 32 and the data width of my DSP Builder system is 1. Do I have to change the data width in the block Avalon-MM Write FIFO and put 32? Or am I doing something wrong?

Thanks.
