C4GX kit dev + TSE without external memory

Hi all, I got a new mistake. I start with the board update portal design from altera. I don't understand why in this design there is a big onchip memory and SSRAM. Can someone explain...

hi, daixiwen

sorry but it's my first experience with ethernet so I don't know how check if ethernet use the descriptor memory...

I found in the file tse_my_system.c the following code 

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)
		
};

has something to do with that you say?:)

PS: I'm using the simpleSocketServer (RGMII) application example project as base and the custom SOPC shown in previous post.

thanks

Ale.
