I don't understand. Can I do authenticate-fpga-config AND
partial-fpga-config?
Yes, but not simultaneously.
Flag authenticate-fpga-config is used to first check the integrity of
the bitstream. If the authentication passes, the user can perform a full
or partial configuration to actually configure the bistream to device.
- partial-fpga-config : boolean, set if partial reconfiguration is to be done,
otherwise full reconfiguration is done.
- external-fpga-config : boolean, set if the FPGA has already been configured
