Do you know to what address space the Marvell PHY is connected to in the Stratix IV GX development board? From the TSE spec I understand that if I use PCS/PMA, addresses 0x200-0x220 are allocated to the PCS. So I assume the PHY is connected to MDIO1, and it's address space in the MAC registers starts at 0x280. But when I try to read from this address space, it looks like I'm not reaching the PHY's registers. I tried to play with the definition of MDIO_ADDR1 (register 0x40 in the MAC), without a success. Any idea how is the PHY connected to the FPGA? Zoe
