Voltage level at FMC Pins

Question

Hi everyone,

I'm currently trying to get a 3.3V output level at some of the FMC pins.
Using a scope I figured out, that also in the unloaded case I only get ~2.5V. My configuration for single ended signals in the xdc file is th following:

set_property PACKAGE_PIN AC16 [get_ports test]
set_property IOSTANDARD LVCMOS33 [get_ports test]
#set_property DRIVE 16 [get_ports test]
set_property PULLUP true [get_ports test]

Are there differences in the max ouput voltage between the different banks?
Do I need to do something more of implementation/configuration/... to ensure the ability of 3.3V output?

Thanks for any hints

I solved my problem: There is the jumper JP7 used to select the voltage supply of the FMC connector. Further details could be found in the "Board-User-Guide" section 2.15.1 'FMC VADJ'
