Oooops,

just found out that the flash programmer does not work at all.

I assumed it deleted the EPCS before programming it.

Instead, the image programmed via quartus still sits there ....(assumed the EPCS got cleared before reprogramming it)

If I do a JIC programming via the SFL then i can dump the config data.....

suggestions?
