If not, feel free to ignore :) Maybe I would highlight two things: a) If you add 'authenticate-fpga-config' you are not allowed to add new nodes b) If you add 'authenticate-fpga-config' you are not alllowed to add other operations > - 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 > Thanks, Moritz
