TMDSICE3359: Disabling one port with PRU-ICSS-EthernetIP Adapter

Stefan B

Part Number: TMDSICE3359

Hi,

whats the right way to disable one of the ethernet ports? I've tried it some time before but PRUs didn't like me approach deactivating the PHYs or change the initialization. How is this done right?

Thank you in advance and best regards,
Stefan

"ICSS_EmacUpdatePhyStatus()" function in the icss-emac driver signals link up to the firmware. You can modify the icss-emac driver so that this function does not get called for the port you want to disable. It gets called from "ICSS_EMacOsLinkTaskFnc()" or "ICSS_EmacPollLink()" function.

sorry for responding so late. I tried something like that:

if (portNum == 2)
{
    linkStatus = 0;
}
else
{
    linkStatus = ((ICSS_EmacObject*)icssEmacHandle->object)->linkStatus[index];
}

Seems to work very fine.

Thank you and best regards
Stefan
