Alt_asmi

Hi, I have a CyCIII connectet to a serial configuration device. I´m able to configure the CYC III with active serial. Now I want to access the Flash with the ALT_ASMI_Parallel_Interface....

I too have a similar issue with a cyc3 . Probing the EPCS16 shows that after FPGA configuration the EPCS nCS signal goes low. When the ASMI function is used to preform a read the nCS is driven high when the operation code is sent out. Sort of behaves as though the nCS is inadvertantly inverted in the megafunction.
