Hi,

I'm also having problems running the Avalon OpenCores Ethernet MAC; one thing I stumbled over is in the "SOPC Builder to QSys Migration Guidelines AN 632", in the chapter "Avalon-MM wait-request Signal". It seems that the notion of the wait-request signal on the Avalon bus has changed. Is this possibly a problem for the current version of the OpenCores Mac?

I've never seen rdreq signal on the rx_dma fifo going up, and it seems to me, that in eth_avalon_rxdma.v it's assumed that the waitrequest is going down ...

Any ideas?
