I recently designed and put together my first FPGA board. I can configure the FPGA over JTAG fine, but the EEPROM seems out of reach. If I use the USB-Blaster in AS mode, it fails to get the device ID, and if I use a .jic file, the process fails, with no explanation. Other than that, the board behaves as desired (so far).
I'm using an EP4CE22E22C8N with an EPCS16 flash chip. They are configured as shown in the Cyclone-IV Handbook on pp. 218. I can configure the FPGA over JTAG, however I cannot configure the EPCS16 over JTAG or the AS header. I've attached the configuration page from my schematic.
Thanks for any help.
