You can use various bin2hex tools for the conversion.
It's however not quite clear what you want to achieve. Why would you store .sof configuration file in on-chip ROM?
Or do you mean, you are converting .sof to .hexout with programming file generator tool? It's intended to program e.g. configuration flash.
In my final design I wanted my FPGA able to receive a new programming file from an external source (possibly a processor), the FPGA will then write the new programming file into flash (EPCQ128A in this case) and use the Remote Update System in conjunction with the flash to update the FPGA.
Currently in the testing phase I don't have my external source setup, so I wanted to try storing the new programming file into a ROM and write the ROM contents into the flash.
