SK-TDA4VM: Unable to receive any GPTP packets

Xiaolu Huang

Part Number: SK-TDA4VM

Tool/software:

Currently, on the SK-TDA4VM board, we have encountered an intermittent issue where the Ethernet interface fails to receive GPTP protocol messages. Using tcpdump and enabling promiscuous mode on the network interface allows the messages to be received again. However, once promiscuous mode is disabled, the messages cannot be received.

Disconnecting and reconnecting the Ethernet cable does not resolve the issue, but using ifconfig eth down/up to reinitialize the driver restores functionality.

The SDK version we are using is Linux 09.02.00.05, and this issue also occurs with earlier SDK versions.

    Hi,

    TDAVM-SK has MCU CPSW2G connectivity with Native Linux driver from SDK.

    Can you please dump ALE entries before the issue and after observing the issue.
    # switch-config --ndev $IF_NAME -d
    Where $IF_NAME is the interface name like eth0.

    Also, please share the Linux Kernel log.

    Best Regards,
    Sudheer
