AM6548: PRU ICSSG Ethernet status

Part Number: AM6548

Hi,

On our custom board we have 4 PRU ICSSG Ethernets, we use the default PRU/ RTU Ethernet binaries from SDK 7.1 for ICSSG Ethernet. 

When we take the interface down by running  ifconfig eth0 down command the eth0 interfaces automatically ups after few seconds. same is the observation with other 3 ethernet interfaces.

Is there any special handling for ICSSG ethernets ?

    Hi,

    No, it shouldn't be the case. Is this on your custom board or the IDK ?

    Regards

    It is on custom board. We dont have SR 2 IDK board. Tried on SR1 IDK did not observe this issue. Here are the logs

    Here if you see we are makeing port down by "ifconfig eth1 down", then it stops and again automatically comes up.

    Hi,

    Re-opening this thread after some time. Apologies.

    Is this issue still open ? I don't see this on the IDK
