preloader & HPS pins

Hello,

I would please like to ask about using HPS pins from FPGA.

If I understand correctly it should be done as folliwing:

1. configuring FPGA with qsys.
2. generating preloader from handoff.

My understand is that no further code change is required in preloader, i.e. all is done automatically as part of preloader image generation.

Is that correct ?

Thank you very much,
