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 >> -- >> 2.7.4 >> > Please clarify, > > Moritz > Regards, Richard
