Failing to run on hardware Nios II

Hi, I am trying to create a memory test program for an old mass produced product. The FPGA is Cyclone IV EP4CGX50. I am trying to use ALTMEMPHY IP because this is what was used in the product and ...

Hi @akaanb ,

Then you have to use other boot method as mentioned before. May be boot from on-chip flash check this link https://www.intel.com/content/www/us/en/docs/programmable/683689/current/processor-booting-from-on-chip-flash-ufm.html then replace the on-chip memory (OCRAM) with external ram (DDR2).

Example design from Design Store:

Thanks,

Best Regards,

Sheng

    Dear Sheng,

    Okay but I don't want to boot from on-chip flash. Product already has an external flash and uses Cyclone IV(as far as I can see it doesn't have an internal flash). We normally use sof and elf file to create a jic file and use it to program flash. But like I said, this application will be used only for repairing and product test purposes. So I power-up the FPGA and then use .sof file to program. After that I build the small mem test application using .sopcinfo file and build the software project. Then I click run-on-hardware to download my program.

    You can quickly check this video to understand my process: https://www.youtube.com/watch?v=oFR4KKOasG4

    So all my process is static and I don't want to download FPGA sof and software elf to flash because this is 1-run test. It is okay that it won't run when we power-off and power-on again.

    Please correct me if any of my expectations are wrong.

    Best Regards.
    Thanks in advance.
