I have Kintex7 board with 128Mb Micron devcie which uses pins RS (23:22). I can prpogram the devcie with iMPACT tool the selction of the RS 23:22 is avaiable. However, when I switch to Vivado Lab Tool 2015.4 and also prior releases the RS 23:22 option is not avaiable. The Flash can not be programmed successfuly. I can erase the devcie but can not program it successfuly due to missing the RS 23:22 selection. any idea how to resolve that?
