how can i configure CycloneII without cable?

hi everybody !!!

First of all, sorry for my english but i'm french. So my problem it's i want to configure a cycloneII without cable (usbblaster, byteblaster...). Actually i want to do this with a microprocesseur as explain in configuration handbook in PS configuration parts and i don't know how to configure the external memory flash (EPCS16) throught the microprocesseur.

i hope i was clear and thanks for your help.

    If you are using an EPCS serial flash, then the configuration can be loaded by the FPGA in AS mode without involving a processor. You still can use a processor to write the flash, but in can be also programmed through the FPGA, e.g. JTAG indirect programming.

    I don't see a particular advantage of the shown configuration schematic.
