100G cmac with Connectx4 Mellanox board

I connected a Mellanox connectx4 100G to a cmac implemented on a kintex ultrascale + board. The cable seems unplugged. No rxaligned neither a connection on the pc side. Any ideas?

fpga to fpga connection ok.

HI

 

Do you see any errors indicated on the rx status bits?

 

Do you see block lock and sync happening and does giving rx_datapath reset recover the link?

 

Check if Mallanox side has AN/LT or FEC enabled?

 

Both sides should have similar capabilities.

Regards,

Satish

Hi Tamango,

 

Check if Mellanox side has AN/LT or RS-FEC enabled.  You will need to have same feature combination for these options to get link up.
