ENET statistics counters on FRDM-K64F

[embeddeddavid]

Hi everyone,

I am running some of the lwIP examples included within the KSDK on a freedom development board (FRDM-K64F). While the examples run ok, all the statistics counters keep holding a zero value. By statistics counters I refer to MIB and Remote Network Monitoring (RFC 2819) registers located at addresses 0x400C0204-0x400C03FF (such as ENET_IEEE_T_OCTETS_OK, ENET_RMON_R_OCTETS, etc.).

Is there anything I am missing? Do these registers have to be explicitly enabled by writing into a specific configuration register?

Any help would be appreciated. Thanks in advance.

Regards,

Hi

    MIBC = (MIB_DISABLE | MIB_CLEAR);                                    // ensure MIB is disabled while resetting and command clear to reset all counters in the maintenance block RAM
    MIBC = 0;

Regards

Mark
