did You add driver control for RGMII in Your system?

Create .c file in Your project and add this: 


/* REQUIRED ONLY IF NETWORK IS RGMII */

   # include "ipport.h"# endif
# include "system.h"# include "altera_avalon_tse.h"# include "altera_avalon_tse_system_info.h"
alt_tse_system_info tse_mac_device = {
        TSE_SYSTEM_EXT_MEM_NO_SHARED_FIFO(TSE_MAC, 0, SGDMA_TX, SGDMA_RX, TSE_PHY_AUTO_ADDRESS, &marvell_cfg_rgmii, DESCRIPTOR_MEMORY)
        
};

This is added in Simple Socket Server RGMII example.

If still not work, check if You can ping Your board?

If not, check timing issues. RGMII bus on gigabit speed is hard to meet timing.
