    Version Found: v17.1
    Bug ID: FB: 553632;

    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








    Workaround/Fix
    To work around this problem, follow the steps below:
    • Generate RPD via Convert Programming Files tool
    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.

    cyclone10使用EPCQ进行boot,可以参考现在都是按照Embedded Design Handbook中5.2.3. Nios II Processor Booting from EPCQ Flash说的合并为jic的方法做。
