The issue of CPPI RAM for EMAC driver

Other Parts Discussed in Thread: AM3715

Hi,

I am porting our TCP/IP stack smxNS on Am3715 EVM board. But I met a problem of CPPI RAM.

When I use Internal SRAM as EMAC descriptor, the EMAC module works OK. But if I use CPPI RAM as EMAC descriptor (All code are same. Only the descriptor address is different.), the EMAC module cannot work.
