Hi. I am developing a Cyclone II - EP2C20AF256I8N FPGA schematic using the EPCS16SI8N memory. I wanted to know if the following schematic is correct to program it through USB BLASTER ALTERA CPLD. If I have any mistake, could you please correct me?
Is it necessary to put the two headers to record it also by AS?Sch_JTAG.png

Hello,
the configuration interface is implemented correctly. You don't need a second AS header, flash will be programmed through JTAG by using JTAG indirect configuration.
