I'm trying to optimize the pin allocation of an existing board. I imported the .brd file into fsp, and checked the Instance Properties of the connector which is connected to the FPGA. There is a group in Group Details, but when I clicked the green arrow in the Connect to Device column,the list is blank. Since in .brd the connector is connected to the FPGA, I'm wondering how I can keep the connections in fsp. I searched online and found a tutorial video at:

It gives an example of creating an fsp project from scratch, but doesn't show how to import. Can anyone give some advice on this? Are there related tutorials available? Thanks.
