11 years agonCONFIG should not be low.
Here's a schematic of a design containing a FLEX10K and EPC2 http://www.ovro.caltech.edu/~dwh/correlator/pdf/correlator_sch_rev_c1.pdf p57 has the EPC2, the net names are prefixed with SC_PS for "System controller passive serial". p69 has the system controller FPGA connections. Note how there is a pull-up on nCONFIG. You will need to do the same. Cheers. Dave
