Hi BadOmen!

Thanks for your elaborate reply, really helped me a lot!

I have a couple of questions left though:

  1. When I create a preloader with the bsp-editor (launched via the SoC EDS 14.0 Command Shell), how do I incorporate the information from Quartus about the pins?

  2. How do I set the drive strength of an HPS pin? For the FPGA, I can set the IO-Standard via the pin properties panel in the Pin Planner in Quartus. However, it's grayed out for HPS pins.

  3. What's the difference between hps pin mux settings and hps I/O settings?

Many thanks,

Adam
