SJA1105 functionnal problem

Question asked by Hasan Ofluoglu on Jun 11, 2018



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?
