NC_setLinkHook issue

Mohammed Fawzy
Expert 1905 points

Hello,

i'm using TM4C129 with XDCtool xdctools_3_31_02_38_core and TI-RTOS tirtos_tivac_2_14_00_10.

and i'm trying to use the NC_setLinkHook to set a hook function to be called up on Ethernet cable is plugged/unplugged.

but the function isn't invoked at all if the Ethernet cable is plugged or unplugged.\

Thanks,

Mohamed fawzy

    Unfortunately the EMAC driver does not support this feature of the NDK. I've opened the following enhancement request.

    SDOCM00119073: The EMAC Driver for TM4C129x devices should call STKEVENT_signal to denote when the link status changes

    There is a EMAC_isLinkUp() API call you can make that queries the driver to return the link status. I know this is not ideal, but it does allow you to periodically poll the driver to determine the link status.
