Hi everyone.this is the part code of the ENET_Init(u32 operatingmode)

void ENET_Init (u32 operatingmode)

{

u32 i;

vu32 regValue;

ENET_MACConfig *MAC_Config;

ENET_MACConfig config;

...

/* Put the PHY in reset mode */

ENET_MIIWriteReg(0x0,MAC_MII_REG_XCR, 0x8000);

/* Delay to assure PHY reset */

for(i=0; i

{

regValue = (u32) i;

}

...

....

}

it means that the address of the PHY is 0x0;but the data which I read from PR20-XMC is 0xaa(PAD4:0 10101).when I think the address of the PHY is 0x00,I also can read ID of PHY(STE100P)and the ID is right.So what I wonder is that what is the address of PHY ,how to define ?In my evaluation board the Mf4:0 is 10111.I appreciate your help.

Best Regards

Follow up question:

what is the proper amount of delay to assure that PHY has been reset?

The datasheet

http://www.st.com/stonline/products/literature/ds/6806.pdf

is not clear on this point.

Any help from ST would be appreciated.
