Do you know How to stop seding abnormal packet by TLK110 itself?

Hi,

I found TLK110 sending abnormal packet at every 0.3sec, eventhough DSP  TMS320C6743 was stopped by emulator.

the message is,

"Ethernet Header" + 46bytes data.

Destination always : 01 80 c2 00 00 01

Source always : 00 08 ee 03 6a c6   <-- my default mac addr.

Type always : 8808

Data always : 0001 FFFF 0000 .... all zeros ... 0000

Do you have any Idea?

How to TLK110 can send packet  without DSP command?

The abnormal packet sending was stopped after initialize TLK110!

Does someone hide their secet code in chips or source, for detecting their elements or program usage in somewhere?

Regards

Suno.

    Suno,

    Based on your description, I believe that you are seeing the packet data after it is received by the link partner of the TLK110.  Is that correct?  Or are you looping back the TLK110 transmit data to the receiver?

    In either case, the TLK110 should not be transmitting packets on its own.  We should confirm that no data is being passed to the TLK110 via the MII.  After you stop the emulator, could you please probe the TX_EN and TXD inputs of the TLK110?
