AM3352: Network communication

Nancy Wang
Expert 8210 points
Part Number: AM3352

Hi,

ti-processor-sdk-linux-rt-am335x-evm-06.01.00.08-Linux-x86-Install.bin

PHY chip TI DP83822 has been identified in kernel boot phase. Why there is no PHY chip showed when loading filesystem, and network port cannot communicate?

    Hi,

    Some of the questions from the checklist are not answered so I can offer only suggestions on what to look at. I will assume that this is this a custom board.

    The first part of the boot does indicate that a PHY was found. But this line says that no such device exists.

    [21.134480] net eth0: phy "4a101000.mdio:9ffcbff8" not found on slave 0, err -19:

    This error code means this no such device

    This output from the ethtool indicates that the PHY is not communicating with the processor as there is not any information being returned concerning PHY capabilities and advertise link modes.

     

    As long as there is not any link detected as part of the ethtool eth0 command then there will not be any network traffic.

    Please attach (do not cut and paste into the post) the complete boot log.

    Also please attach (do not cut and paste into the post) the board DTS that you created for the board.

    Best Regards,

    Schuyler

    Hi,

    Since I have not heard back I will assume that you were able to move past the issue and close the thread.
