Hello Vaibhav and Dan, Thanks for sharing the additional information. We will have our hardware team review this. [quote userid="576780" url="~/support/processors-group/processors/f/processors-forum/1343344/am6422-icssg_prueth-port-initializing-but-not-able-to-connect/5185260#5185260"] Can you try testing the icssg ethernet interface at 10Mbps? The idea is to configure to a lower speed to drop the RX clock rate down to a lower speed, to help make the MAC more tolerant of any timing issues. The goal is to check if rx_good_frames are detected or at the very least if we can see more than just a single rx_crc_error. You can do this by using "ethtool -s eth2 speed 10" and make sure to do the equivalent for your host PC/link partner.[/quote] Can you try this as well and let us know about your findings? While this doesn't not directly solve the issue, it would give us more clues about why it seems like the ARP reply message is not being detected at all on the RX path of the icssg ethernet interface (no rx_good_frames, and only single digit crc_error_frames etc). -Daolin
