Unable to Program EPCS16 in system

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...

I can configure the FPGA over JTAG, however I cannot configure the EPCS16 over JTAG or the AS header.

As far as I know EPCS16 over JTAG can be programmed only in the setup according to Figure 8–29 and its very convenient.

If setup is according to Figure 8–28, then You can only program EPCS16 through AS Mode using appropriate 2x5 pin header.

Maybe someone else would help You with AS Mode. I never studied or used it ....
