Hi Jan, I solve my problem of GPIO which comes from a bad address.
So I could measure the time to write a packet on the dm9000, It takes 200 µs for a packet of 1000 bytes. I had cheked if someone has ever try to use dma, but I don't find anything, maybe there is a reason. I'm afraid it need lots of works to modify it for dma, isn't it ? Thankfully, WALLOIS Cyril
