Dear Experts :
we design new ethernet T1 phy chip (Marvel 88Q1110) for CPSW9G switch on our customer TDA4 board, The PC and the board are connected to the same switch.
my question is :
1. TDA4 drop packet when ping PC sometime? PC ip:192.168.0.5, eth1 ip:192.168.0.12
root@j7-evm:~#
root@j7-evm:~# ping 192.168.0.5

64 bytes from 192.168.0.5: seq=7 ttl=64 time=0.365 ms
