Replying to myself here. Resolved part of my query..
Ok, within the Assignment editor can also see further down the list the location assignment PIN_E5 for fpga_nconfig. So I could see that the 2 following location assignments I defined within my .qsf were both listed within the Assignmenr Editor window
set_location_assignment PIN_E5 -to fpga_nconfig
set_instance_assignment -name WEAK_PULL_UP_RESISTOR ON -to fpga_nconfig
Q/ BUT is is ok to set a WEAK_PULL_UP_RESISTOR on an output port ?
If this is not ok, I must go and set this up from the FPGA side which is declared as an input port.
But it will not resolve the problem I am trying to resolve at the moment ie to why nconfig is pulled low after programming/configuring the loadware PFL code before even autodetecting the flash to program it with the main application code that later on should configure the FPGA

Can someone please answer my following question before end of the day, so I can attempt to try it out to see if it resolves my problem ?
Q / Is is ok to set a WEAK_PULL_UP_RESISTOR on an output port ?
& can I set a WEAK_PULL_UP_RESISTOR on a port that has already an external pull-up resistor of 10K ?

Tried the weak pull up resistor BUT it did not resolve the issue I had !
