How to configure an EPCS with a .rbf file?

Hello, 

 

 

I am using an IP SPI core to communicate with an EPCS128 device and write a specific .rpd file into it. It works fine! However, a .rpd file is too big (16MB), so, I tried to write a .rbf that configures only the blocks of memory to be used (two blocks). 

To do that, I had erased all blocks of memory to be used and I wrote the .rbf file into EPCS. The write procedure works fine, but this approach was not able to configure the FPGA correctly. 

I wonder if there is same procedure I am missing to be able to update the FPGA through a .rbf file? 

 

 

Thanks in advance.

Its been a while since I played with EPCS, but I recall that you need to be using the .rpd file format, and there is a bit-order change required for programming SPI flash. 

 

I believe this is all discussed in the SRunner documentation.
