Does the rest of this work? You can actually transmit/receive frames, but it is a 10/Half? So the MAC is working, just the PHY is missing? > My simple tries, write 0xsomeval everywhere, lead to something, phy/eeprom return now 0x000y. > Probably, this chip doesnt have any PHY... If you look at dm9601_mdio_write() and dm9601_mdio_read() it always passes 1. 0 is used for the EEPROM, at least in a real device. so try 1-31 and see if you get anything interesting. Andrew
