Hello to everybody.

I'am using cyclone III dev kit, marvell 88e1111 PHY, Triple Speed Ethernet and nios II.

i want to initialize PHY.

i try to write code for initializing, but i don't know how to address PHY through the MDIO.

in tse_regs.h there is

IORD_ALTERA_TSEMAC_MDIO(base, mdio, reg_num)

IORD_16DIRECT(base, 0x200 + (mdio * 0x80) + (reg_num * sizeof(alt_u32)) )

i think i can use it, but what are the parameters?

base - tse_mac_base?

mdio - The MDIO address of the PHY device is configured to the value 18 (0x12)?
