Hello, 

I'm developping a board having a cpu, three cyclone2, max2, and flash rom. The max2 is used as pfl to program flash rom. The flash rom is written from the cpu. Generally you use pof format to program flash from jtag through pfl and rbf format from cpu, but I want to use same format for both. Do someone know it is possible? The pof file has three pages that contains one fpga data. 

Thanks,

I guess it is possible to use the .pof file from your CPU. 

 

You will somehow need to figure out how to strip out the "payload" part of your .pof file so that the CPU can treat it like raw binary data. Or you could write you own downloader program running in the CPU to look like the Altera JTAG downloader program, and drive the MaxII JTAG lines to program the FLASH. 

 

But why? 

The .rbf file is already created for you for that purpose. 

 

Just wondering?
