Hi softwind555,

Did you check if there are any inclk 125MHz? Also did your reset pull high or pull low?

Not all the GPIO support the LVDS serdes though, you might need to look into pin with DIFFIO function in them. You can find that in the pin planner or the pinout file.

Also I do not think you will need the g_out. You can straight away assign the lvdsout as an output pin. Then make sure all your pins are connected on the board.
