Hi,
I’m using x2 w5500 in my project recommended by AVNET distribution in Israel.
The w5500 is connected to internal switch and other external ports.
I didn’t use magnetics because the short distance in the board.
The configuration is UDP and all the PMODE is set to ‘1’.
I having a number of problems:
• Sending UDP message towards the PC port cause the following:
Wiznet send ARP request the PC is responding with ARP response. The response is not received by the Wiznet that set timeout interrupt.
• Reading phycfgr register we notice the value 0xbb that indicates the status of the line as half duplex/100BastT/Auto negotiation.
• Trying to change the code to work 10M with no Auto negotiation rarely works.
I need your help as soon as possible.
I can Email you the schematics if needed.
Thank you,
Meir.
i added the schematics, please see if the TX/RX line are ok.
