Thank you for recommending.

I think to purchase C10 GX dev kit board + Bitec DP daughter card, There are many function so when I load my design, Board document doesn't show how to initialize state to avoid high current in unused pin in my design but kit board connected some part. so I can't use that kit board to verify my design. I just use circuit reference only.

I understood rx_is_lockedtodata signal behaver.

Since DP signal goes to FPGA through repeater chip (SN75DP130SSRGR) , it may be necessary to configure the repeater chip. I am not sure but I think the PC configured analog value of repeater chip through DPCD. so I didn't touch repeater chip register. If you have any information to control repeater chip (SN75DP130SSRGR), give me document.

Thank you

Michael
