Honored ContributorCYCLONE III(EP3C120) Development Kit configuration from flash
Hi all,
I have a qsys design which include a nios II processor. I want to load my .sof and .elf files to flash to configure FPGA from flash directly on power up. In the design I have added a cfi controller and set the CPU reset vector to the cfi flash. However when I have tried to download .sof and .elf by using Nios flash programmer, it gave me this error: Info: Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Info: Resetting and pausing target processor: OK Info: Reading System ID at address 0x06081140: verified Info: No CFI table found at address 0x02000000 Info: Original contents (after writing 0xF0 and 0xFF to address 0x02000000): Info: 0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

Is there anyone managing to configure from flash on that board with the qsys design? Also, Is there another way loading flash to .elf file other than using nios flash programmer I think there isn't?
