Hi,

- We need to send data from one Cyclone III development board to two receivers. One of these receivers is a displaying panel while the other one is sent to another cyclone III development board (that is connected to a displaying panel too).

- This is implemented as shown in the attached image, by branching the required signals like mdio, mdc,data,.. .

When assigning the mdio to two pins one of them is D2 in bank 1 and the other one is the already assigned pin in cyclone III development board (AB2) "PHY not found in PHY profile" error occurred. If changing the pin location to IOBANK_1 , the connection is successfully established & there is no error detected.

Kindly note that this error occurred without connecting the second board?

Can any one help us.

Thanks & Regards
