Why does the sof2flash utility fail to work with EPCQ device in Intel® Arria® 10, Intel® Cyclone® 10 and Intel® Stratix® 10 designs?
Description
Due to a problem in the Intel® Quartus® Prime Design Software version 17.1 and earlier, the sof2flash utility may fail to work with EPCQ device in Intel® Arria® 10, Intel® Cyclone® 10 and Intel® Stratix® 10 designs. The following error message may be seen: sof2flash: Unrecognized device family in SOF

quartus_cpf -c --device=<EPCQ flash density> -o auto_create_rpd=on -o rpd_little_endian=off <SOF filename> <POF filename> Example: quartus_cpf -c --device=EPCQ64 -o auto_create_rpd=on -o rpd_little_endian=off c10lp_gsrd.sof c10lp_gsrd.pof - Convert RPD to .flash via nios2-elf-objcopy tool
nios2-elf-objcopy -I binary -O srec --srec-forceS3 --srec-len 32 <RPD filename> <FLASH filename> Example: nios2-elf-objcopy -I binary -O srec --srec-forceS3 --srec-len 32 c10lp_gsrd_auto.rpd c10lp_gsrd.flash This problem is scheduled to be fixed in a future version of the Intel® Quartus® Prime Design Software.
