Downloading project to EPCS64

Hi everyone,

i'm having some problems downloading my design in epcs (EPCS64 on Nios II development board, stratix II edition).

I want to download .sof and .elf in epcs using quartus ii programmer (in active serial mode) and epcs connector on my board.

I use this method: first, i generated sopc system with nios reset vector pointing to epcs; then i generated sof (with quartus) and elf (with ide).

Then i followed this instructions to generate .pof file http://www.altera.com/support/kdb/solution...112006_450.html (http://www.altera.com/support/kdb/solutions/rd04112006_450.html) and then i downloaded it to my board using active serial mode.

When i reboot my board, it's not loaded my project but factory design; it seems that boot loader try to load it, but it doesn't, and then it loaded factory configuration.

Any idea?

Thank you!

    I was able to download sof + elf to epcs64 on my board using epcs connector.

    In fact i set onchip mem as nios reset vector (in sopc builder) and i set onchip mem for .text, .rodata, . rwdata in IDE -> system library properties.

    Then i generated onchip_mem.hex and recompile quartus project to include .hex in .sof/.pof. I downloaded .pof to epcs using active serial and i noticed that software ran.

    But if i try to change nios reset vector to epcs_controller and if i use the method posted before, it doesn't work. After downloading .pof, hardware configuration seems to work but software doesn't run.

    Any idea about this?

    Thank you.
