Format to use for configuration image for Flash programming via ota in cyclone V E

Hi,

iam using cyclone V e series fpga with a OTA update support, iam sending fpga configuration image over usb interface to fpga , where in fpga serial flash controller logic receives and flashes fpga image into a QSPI flash (S25FL256L) via ASMI block active serial interface. Then booting new image via reconfiguration IP block from same ASMI interface.

So related to that i have few questions

1] What Format configuration image can i used for via above method of programming? like .sof, .rbf, ..pof, etc?

-->

2] Can i use POF file converted from sof file with setting as configuration device = S25FL128 and active serial mode , on a Flash memory S25FL256 ? is that feasible?

-->

3] we want to have to different set of configuration image on S25FL256L qspi flash at location (0x0000_0000 & 0x0100_0000 respectively) so can we have option in question 2 above? can use compress image file in QSPI?

-->

thanks & regards,

Snehal B.

    Please find my response below:

    You may use JIC, RPD and POF for Active Serial configuration scheme.
