Hi

I got the new board and Still doesn't work DisplayPort.

I attached two picture.

Picture 1 : cyclone 10gx transceiver PHY user Guide (20.1) page 259

Picture 1: I probing from my board.

In my system, the rx_is_lockedtodata signal is always low (it is problem)

Can you advice how to make it to work ?

My concern is rx_cal_busy and rx_analogreset signal is overlapping (?)

I didn't change anything in bitec-reconfig_alt_c10.v and xcve_reconfig_arbiter.sv.
