Cyclone V Configuration

Hi, I am using 5CEBA9F23C7 and EPCQ64A as configuration flash. When I select Active Serial X4 configuration. the pof file by default has EPCQ256. Is there any Flash selection user guide for Cyc...

Hi SK,


If you are configuring using AS x4 mode, i would suggest you generate JIC instead of POF. POF is meant for PS / FPP mode.


Meanwhile for configuration device selection, you just select EPCQ64 will do. Select the configuration device that you are using.


Thank You

    Hi,

    I created jic and tested. But the jic file size is also 32769KB. EPCQ64 will not support this file size.

    So I had to use MT25QL256 Flash device. I have enabled the "Generate compressed bitstream" option in the configuration settings.

    But when I create auto rpd along with pof the file size is 12MB.

    I have to program the FPGA image and NIOS application image to the flash via jtag.

    Please help me to understand how this can be done. I would also like to know the difference between rbf and rpd files.
