Ethernet MAC

Daixiwen,

Thats great to know. I was getting high speeds for UDP receive (Board side) but not sending. I am trying everything at the moment to make my design more effecient. I am using basically all the suggestions of the Ethernet Benchmarking Example, however cannot get the c2h compiler working for alt_cksum. I get an error in Nios saying that there are too many connections to the tightly coupled data master, however sopc suggests that it is only packet_memory attached.. so i have to error check that one today.

With regard to placing key funcutions in the tci memory, are you referring to changing the Linker Script memory allocations in system properties of Nios? ie. Program memory -> memory attached to tightly coupled instruction master?

Thanks alot,

D.
