Download NIOS2 software from external flash memory

Hello everyone!

I'm trying to make my NIOS2 download code from flash device. I sucsessfuly programmed hardware design into flash memory, but the software does not start when i reset my board. I've made everything according to user guides, but it seems they are not full. In my qsys I have nios2 cpu, on-chip memory, jtag uart and a couple of custom cores. Is it enough, or i need something else? I could not have find a proper guide for this.

Normally I programm my flash using NIOS2 command shell. I wanted to try programm flash device using flash programmer but, when i attach .sopcinfo file (I use special Altera's file for my board) it shows me strange error: "SEVERE: System ID does not have a valid number format". For some reason Expected system id is 0xfffffffffacecafe, instead of only 0xfacecafe. I cant find how to resolve this problem.

Could anyone advice me something, or give a link to a guide? I'm sorry if my questions seem silly, I'm only a novice in this area.

Thank you!
