I have a board with a Cyclone V that is using Active Serial Configuration from a Micron MT25Q(512Mbit) flash.
I have enabled MT25Q device selection for Quartus with pgm_allow_mt25q=on
Using NIOS II Flash Programmer download both SOF and ELF file, neither of them load after power-up. After running quartus_pgm --nios2 from the command line with the --debug parameter, it returns the flash ID correct and recognize the flash as EPCS-20BA20
The only way work for me is using Convert Programming File tool, convert the SOF file to JIC file and downloaded it to the flash through Quartus Programmer. FPGA works fine after power-up.
But Convert Programming File tool can't convert ELF file.
