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...

Are you sure that the Ethernet driver is using the descriptor_memory to store the descriptors? As the SGDMA's descriptor masters are only connected to that memory, the DMAs will freeze if you try to use them with descriptors in main memory.
