Regular ContributorHi Dragan,
RBF file is meant for Passive Serial configuration scheme. I believe you should use RPD file instead.

For RPD file, during the generation of it, you may need to set the order format to "Big Endian". To do so, select "Convert Programming File" on Quartus, then select "Options/Boot info.." and then select "Big Endian".

New ContributorHello SooYL,
thank you for answer.
For flashing old FPGA flash EPCQ128N we use RBF file and due to we try to generate correct RBF file flashing new FPGA flash EPCQ128A as well.
We have tried with RPD, but size of that file was bigger than size of FPGA flash which is available from Linux.
Anyhow we will try to generate RPD according your suggestion.
JIC and RBF, which were generated for old FPGA flash EPCQ128N (Quartus 15.0.0 was used), have same sequences at the beginning of files:
JIC: ...6A 6A 6A 6A 36 F0 ...
RBF: ...6A 6A 6A 6A 36 F0 ...
while JIC and RBF, which are generated for new FPGA flash EPCQ128A (Quartus 18.1.0 is used), have different sequences at the beginning of files:
JIC: ...AF A6 A6 A6 66 03...
RBF: ...6A 6A 6A 6A 36 F0 ...
Have you noticed differences above? Do you have some explanation?
Regards,
Dragan
