12 years ago --- Quote Start --- 1. spec says msel should be gnd(0000) for JTAG Configurtion. it looks fine. 2. Doubt the BGA soldering on conf_done pin. because pull-up itself is not working. 3. Total 70 Devices are detected included the last EP3C25F device as shown. Checked the configurations on pull-up/down with device(3.3V IO) and USB Blaster (3.3V Power) and VCCA, VCCINT, VCCIO. all looks folow the spec. Determining the resodering the Device. Any suggestions ? --- Quote End --- 1. JTAG configuration can be implemented without any settings. 2. What you mean "looks fine"? Is it mean that you can program fpga thru JTAG correctly? 3. How many fpga devices in your single jtag chain? One or multiple?
