DP83TD510E-EVM: Any sample script for testing communication distance?

Part Number: DP83TD510E-EVM
Other Parts Discussed in Thread: USB-2-MDIO

Hi Team, 

My customer is configurating 2 DP83TD510E-EVM as below.

PC - (Ethernet cable) - EVM1 - (SPE cable) - EVM2 -(Ethernet cable) - PC

Customer wants to send Ping from one PC to communicate with another and see the distance when error happens. 

Customer is thinking set register to 2.4V-p2p mode by USB-2-MDIO to test SPE available communication distance, 

do TI have any sample script can be read by MDIO tool and can share to customer?

Thanks.

Regards,

Jo

    Hello Jo, 

    Understand.

    I am already checking with the team on availability of the script and update you in the next couple of days.

    We have tested the distance with 1V and 2.4V p-p. May be customer can use the same approach.

    Hello Jo, 

    Good morning. Please see attached.

    Scripts :

    • Reverse_loopback_enable : to enable reverse loopback on the link-partner side.
    • Packet_gen_enable : to enable packets generation towards copper side on DUT
    • Packet_checker : to check the link and packet errors and number of packets received
      Fullscreen reverse_loopback_enable.txt Download 
      begin
0016 0110 //enable reverse loopback to send the data back on cable
end
      Fullscreen packet_gen_enable.txt Download 
      begin
001F 8000 //reset the part
0119 155F //enable packet generation towards cable and packet checker coming back from the cable
001F 4000 //soft reset
end
      Fullscreen packet_checker.txt Download 
      begin
0010 		//x0010 should read 0x0001 for succesful link-up
011F 0001	//latches the packets received and error status
011F		//should read x0B00 for PRBS lock
011D		//
011E		//number of packets received is 32bits number with lower 16bits as value of 011D and higher 16bits as value of 011E
0121		//
0122		//number of errors received is 32bits number with lower 16bits as value of 0121 and higher 16bits as value of 0122
end
