Config via Protocol - periphery IO default voltage levels

Hi Simon,I'm also using CvP now. My understanding is that while in CvP mode, you can't hold various I/O at predetermined levels but tri-stated. You might need external on-board resistor pair to achieve your predetermined levels. I encountered a problem that if I enable CvP and "open ("/dev/altera_cvp", O_RDWR);" and try to access BAR registers, it seems I loss control of the board. Do I need to modify the Sample CvP Linux driver?Br,aroamerer

I've started using Configuration via Protocol and I can get my board periphery loaded in time for PCIE and I can get the core programmed once Linux has booted on the host. In the meantime, it would be nice to be able to hold various I/O at predetermined levels so that while the core isn't configured other components on the board can behave in a default state.I'm not using the partitioned design principle as I'm using Quartus Prime Lite, so was wondering how I can persuade Quartus to default some I/O to predetermined levels in the periphery file.Cheers,Simon
