Yes I would think so. But if you have the memory it might be a good idea to increase the number of buffers from 16 to much higher, say 32, 48, or 64. 16x128 is only 2048 bytes total. That's not a lot of buffer space, either for the EMAC or lwIP. But I do not know how the memory is laid out or setup for that part. Chris.
