Binary format for Stratix IV Image in a NOR CFI Flash?

Awesome! Thanks shuckc, exactly what I needed.

I spent some time trying to figure out why when I convert a sof to rbf directly using the quartus_cpf command

i.e. quartus_cpf -c <input_sof_file> <output_rbf_file>

the rbf file would not match what I saw in the flash (i.e. it lacks the "PFL/.pof packetisation" headers you mentioned).

However, your method of sof->pof->hexout->rbf matches what I see in the flash.

It is unfortunate that Altera provides different ways to generate a rbf file from an sof, each with different results.

I wish Altera would make these things more obvious instead of searching through forum posts and knowledgebase tickets for obscure details.
