Nios Flash Programmer - Getting error - "EPCS Registers Not found"

Hi ,

Im using NiosII Flash programmer to program FPGA binary file (.SOF) and software binary file (.ELF) to EPCS64 device. While downloading im getting error as "EPCS Registera Not found". I have seen in below link its telling like for version 1.1 Errata Nios II flash programmer is not supporting EPCS64 and in future version this support will be added. Now im using Quartusii 11.1 and Nios EDS 11.1 . FPGA device used is Stratix-II EP2S60F20I0.

Please check and let me know how can i program application (both .sof and .elf ) to EPCS64.

Thanks & Regards

Preeti

    Hi,

    Before using the flash programmer did you first download a design (SOF) containing as a minimum a NIOS II processor, some memory, and an EPCS interface? Are you specifying the base address of the EPCS controller on the command line of the flash programmer?

    Mark.
