Ethernet PHY Interface KS8721 with SAM9260 - Urgent Query

Hi Everybody,

I am using Olimex board, need to write the driver for interfacing
AT91SAM9260 with KS8721BL PHY chip.
Now i doing a simple basic emac project from IAR to interface EMAC with
Micrel PHY.
I am beginner with ethernet as well as driver concepts.
In Micrel KS8721BL datasheet, not clearly mentioned about the power on reset
pins configuration. or given less details about working and configuration.
Some queries below,
1) Which are the pins are need to be configured with power on reset.
2) What is the need for the separate pins configuration during power on
reset initially and normal running.

Hi,

I think the olimex board already has KS8721BL PHY chip.The Linux source that
olimex gives already has drivers for this.

Hello TVRPrasad,

The Olimex board has that KS8721 PHY chip. But i am not using the Linux
source, just programming the board without any OS as per requirement. There
are few examples of ethernet driver for PHY DS9161 available from the IAR. I
don't know much about Linux source.

My requirement is to write a Ethernet driver for the the bare AT91SAM9260
with PHY 8721. I am using SAMBA bootloader and also J Link debugger.

I would be very thankful for further details about this interface.
