Hi,

Near the end of .pof file, you can see, as Dsl said, "mPage_0 00000000 0226A5F8;" the last number seems to be the data size in bits.

does it mean that i can write user data, to epcs, from offset (0x0226a5f8 / 8) ? (through ASMI_parallel component)

note : you can know the size of programming data with :

sof2flash --input=your_sof_file.sof --ouput=dummy.flash --offset=0x00

nios2-elf-size dummy.flash

this size, in bytes, may be different from (supposed) data size in bits found at the end of .pof file because of compression (see quartus>asignments>devices...)
