Problems with accessing PHYs on T1042D4RDB

Hi,
I'm working with the T1042D4RDB evaluation board with the original configuration (SRDS_PRTCL_S1: 0x86).
According to the board reference manual, the 5 PHYs are attached to EMI1 with PHY_ADDR 0x01..0x05.
My question now is: through which registers in the CCSR the PHYs on EMI1 are accessible?
I tried MDIO_CTL and MDIO_DATA on all 5 EMACs, using Clause 22, but I got no response by any PHY. However, the bit MDIO_RD_ER is not set.
Can anyone give me a hint?

 

Kind regards,
Arno
