Hi,

 

 

I am trying to implement 1Gsps Ethernet, for that i want to connect exernal PHY device using SGMII mode.

To implement above i have taken Two IP core 

1. tri_mode_eth_mac_v5_5(evaluate the core)

2. gig_eth_pcs_pma_v11_5

and i made all the inter connections between them and synthesis also fine now the problem is when i programed the KC705 the link is not establishing.

my board is KC705, Xilinx version is 14.4.

is there any thing that i have missed or i need to be done.

Praveen g

Hi

 

Have you enabled Autonegotiation at both ends.

 

Is the link struct at Auntonegotiation or synchronization step.

 

Try the suggestions mentioned in the debugging section of PG047
