i have developed my FPGA board using EP1C3T100(CYCLONE) .I use "AS+JTAG"
configration model,but! when i config my FPGA using JTAG ,the log show"can't access JTAG chain".when i using "AS" model ,it can programe EPCS1 chip, but the verifcation is wrong.i have example my board several times. but i can find why?
