quartus_cpf - converting sof file to encrypted pof (with ekp included) for Max 10 FPGA

Hello everyone, I am trying to convert sof file to encrypted pof with ekp inside it using quartus_cpf command. Unfortunately after invoking the following: quartus_cpf -c -k epof_key.key:key_0 ...

    Hi DamBam,


    There's a workaround provided by the engineering as below:

    There are 2 ways to do this in command line:

    1) Program the EKP and POF files separately.

    Example:

    quartus_pgm -c 1 -m jtag -o "p;test.ekp"

    quartus_pgm -c 1 -m jtag -o "p;test.pof"


    The outcome is the same as combine the EKP into the POF and program altogether.

    For POF file, you need to ensure the "Allow encrypted POF only" option is disabled (default is disabled if you didn't make any change) when you generate using quartus_cpf.

    For details, you can refer to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_config.pdf


    2) Save your GUI settings into a CDF file and play the CDF file in quartus_pgm

    Steps:

    a) Setup your settings in the GUI


    b) Click File->Save As... and save the settings into a CDF file (test.cdf).


    c) Play the CDF file in quartus_pgm:

    quartus_pgm -c 1 test.cdf


    Hope this works.

    Hi Fakhrul.

    I tried what you suggested.

    quartus_pgm -c 1 -m jtag -o "p;test.ekp"

    quartus_pgm -c 1 -m jtag -o "p;test.pof"

    Only the pof gets loaded. The ekp does not even though there is no errors or indication that there is failure. How do I know it doesn't work? Well.... I made a simple design to blink the LED and the LED did not blink. I tried step 2 but the cdf wasn't working.

    I am using the Max10 part which requires the Quartus Standard edition. Could this be the problem?

    Thank you!
