Configuration of the SPI flash

Hi,

I am trying to configure a Cyclone V FPGA using an external SPI flash (EPCQ256). I have a confusion in creating separate starting addresses for the default configuration and the upgrade configuration.

While converting the SOF file to JIC file using the Quartus , I was able to give the starting address of page_0 as 0x00000000h. I am not able to separate out another page or give another address which will be start address for my upgrade configuration. I am trouble finding out the exact procedure on how to do it. Can anyone guide me through on how to do it.

Thanks,

Sid

    Having added multiple 'Sof Pages', each will appear labelled 'Page_0', 'Page_1' etc., with the 'Start Address' specified as 'auto'.

    Select the row of the page whose start addres you want to specify. Click 'Properties' and either: select the page you need; or explicitly specify a Start address under 'Address mode for selected pages'.

    Cheers,
