SJA1105 functionnal/configuration problem

[hasanofluoglu]

Hi,

I have a nxp switch (SJA1105ELY). 

This switch is connected (RMII) to a μc at port 0 and two PHY (RMII) ports 1 and 2. I configured the clock and configuration of this switch. With my PHY 1, I try to ping. The switch receives an ARP frame broadcast (FF: FF: FF: FF: FF: FF), my μc receives the frame, it processes it and sends back the answer. But the switch does not transmit anything to the PHY. I suspected MAC filtering but in the general settings I put no filter.

Will you have a solution?

Hi Hasan, 

On my board, the eth0 behaves the same way, I can see ARP request comes in and the uC sends out reply, but the host doesn't see the reply at all, the switch certainly did something bad to those replies. Could you figure out the problem? If you have any idea to debug this, I really appreciate. Thank you.
