Interfacing of Nios-II and Triple Speed Ethernet in Qsys in MII Mode

Hi, In our design we migrate communication to ethernet port. We have Cyclone-IV (E) EP4CE55F484 FPGA with DP83848C Ethernet PHY. We try to interfacing Ethernet PHY with Nios-II. We are using...

Thanks, i already gone through this design. But that design having TSE which is configured as 10/100/1000MB ETHERNET MAC and RGMII Mode.

As we want configure TSE as 10/100MB SMALL MAC and MII Mode. So SGDMA will support MII Mode (10/100MB SMALL MAC)?

Waiting for your reply.
