Trouble with EPCS64

I am working on a custom design using a Stratix II EP2S15 and a EPCS64 as my configuration device. I am using the Flash Programmer utility to program the EPCS so that it will load my FPGA des...

Hi,

I think, the older version of Nios II flash programmer allowed for the programming of FPGA configuration in EPCS memories, but the new versions don't. The new versions allow for only cfi flash memory programming for FPGA configuration data even with an EPCS controller instantiated in the system. I think you'll need to program both separately: Use Quartus II programmer to program the .pof file and use the Nios II flash programmer to program the .elf file. May be someone else can suggest a way to program the .pof file in EPCS memory through Nios II flash programmer, if it exists.

Cheers,

BD
