Do you have a solution meanwhile?

May be I can help. I'm using StratixII and EPCS64. With the following commands I programm the EPCS.

# load SOF

nios2-configure-sof --cable='USB-Blaster [USB-0]' my_hw_design.sof

# generate EPCS images

sof2flash --epcs --input=my_hw_design.sof --output=my_hw_design.flash

elf2flash --epcs --after=my_hw_design.flash --input=my_firmware.elf --output=my_firmware.flash

# flash EPCS first with FPGA configuration

nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x21000 my_hw_design.flas

# flash EPCS with Nios firmware

nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x21000 my_firmware.flash

If you do so you didn't need the quartus programmer and conversion of programming files in Quartus.

Cyclone3 has 4 MSEL pins, you set just 0:2 it this correct?

For the [EPCS-000000] problem I have just an idea. Some serial configuration devices (if they not original from Altera) need a description of their structure. Therefore you need a file called "nios2-flash-override.txt" in the C:\altera\72\nios2eds\bin\ directory.

I have attached an examle file for EPCS128.
