Loading .rbf file into EPCS16 for remote configuration of FPGA.

Hi, I have prepared a qsys design(Say in quartus_project_a) for writing and reading bytes with EPCS16 using SPI protocol(I am using EP3C25F25C68 FPGA) and it is working properly. Now, I want t...

Raw Binary Files containing configuration data for the sequential Passive Parallel Synchronous (PPS), Passive Parallel Asynchronous (PPA), and Passive Serial (PS) configuration schemes. You want to use AS scheme. The POF file is a configuration file for AS that is designed to be used by the Byte-Blaster device, in order to write the configuration data into the EPCS device. The POF file contains not only the configuration data but some other data as well, that is used by the Byte Blaster. As you want to write the configuration data directly to the EPCS from the file you cannot use the POF file directly.

The RPD file which can be converted from the POF file is a raw programming file, which contains the configuration data and nothing else. If you use the RPD file you are sure to be writing only the configuration data into the EPCS and no other unwanted data.
