Help with A10 Backplane Auto Negotiation

Hi Chee Pin, Answer to your questions:

I cannot perform the loopback on the copper backplane. I tried internal serial loopback. The Link stays in AN mode (does not exit). For some reason, the rx_parallel_data_navtive[63:0] is stuck at 0100009C0100009C0h

I have not yet done Simulation. I will try that in next couple of days.

At top level I see: pcs_mode[5:0] = 00001 | all LED signals are LOW | rx_data_ready=0 | rx_block_lock=0 | rx_hi_ber=0

I will attach the IP .qsys file with this update. Please rename the file to .qsys (I had to change extension because this website wont allow me to upload the file as-is).

I did a experiment: I forced 10G mode on the FPGA and AMD SoC. I am able to pass 10g traffic when both are forced to 10g mode. This tell me that the two PHYs and the physical connection are doing what they are supposed to do.

Please let me know what you think. Thank You in advance!
