Cyclone III Serial FlashLoader

I would like to design my Cyclone III board to use the "Serial FlashLoader" (with a JTAG connector and an serial config device). The documentation claims you can do it but Quartus (v7.0) doesn'...

Hi every body,

I want to know how I connect the JTAG to assure the Serial Flash Loader for a CYCLON III FPGA (EP3C25Q240).

I know that I must use the SFL function and connect the M25P16 FLASH RAM like this :

M25p16 EPCS16

C-----------DCLK

D-----------ASDI

Q-----------DATA

S-----------NCS

W-----------VCC (With pullup)

HOLD-------VCC (With pullup)

VCC--------VCC

VSS--------GND

But to program the FLASH via the JTAG ,I don’t know if there is a special connection between the CYCLON III and the M25P16

Thanks
