We have a few instances of W7500P-S2E crashing during the operating. The chip was working fine for a few days, then lost its connection. Neither from Ethernet side (port 5000 and 50001) nor from serial port side can access the chip. The only way to bring the connection back is using Wiznet ISP tool to reload the code and then use WizMAC tool to set the IP.
Would you have any suggestion of debugging this issue?
