Avalon-MM to Avalon-ST On Chip FIFO Memory SOPC

Hey everyone!

We're trying to use an on chip memory fifo in SOPC that converts Avalon-MM to Avalon-ST.

The on-chip fifo memory sends the data through an Avalon-ST source and a custom component that has Avalon-ST sink receiving it.

A custom component is used to export the avalon-st sink signals to the outputs external of the SOPC.

When sending data to the fifo with the Avalon-MM write nios commAND, the fifo (ST-Sink) outputs only two bytes from the message, without a valid coming along with the eop.

What could the problem be?

Could it be the export of the Avalon-ST sink outside the SOPC?

Thanks in advance, Omri.
