TDA4VM: Occasional packet loss of tda4 internal Ethernet

Part Number: TDA4VM

 During the continuous Ping test of tc397 using scripts, we found that occasionally the Ping failed.Viewing the printed log shows that at the time node where the error occurred, tda4 did not send a packet to tc397 (TX did not increase).On the other two tda4a and B boards, the MCU domain of board B and the main domain network port of board a are connected. Board B continues to Ping board a without Ping failure.

I need Ti experts to help analyze it. Thank you!

    Ling, 

    not sure if you root cause the issue. If not, you may want to try the reverse ping on the same link and see if TDA missing reply packages. and, it was not clear whether the failed port is cpsw2g (thus RGMII) or CPSW9G (RGMII/SGMII). please confirm if we need to further debug.
