Honored ContributorCan I make stand-alone NiosII system?
Hi,all.
I am going to build the stand-alone NiosII system. Already, I could build PC-connecting NiosII system but I don't know how to build the stand-alone (so PC-NOT-connecting) NiosII system. What I programmed system is volatile. So I think that it is a correct answer to program the system data into a flashmemorydevice. But the system has NO flashmemorydevice.(in Qsys system,Flash Memory Interface) Can I make stand-alone NiosII system? Though I think I only add Flash Memory Interface, I don't know how to connect it to the other component. Please tell me. Thanks all.15 Replies
Altera_ForumHi, thanks all.
I'll try to read "Configuration and Remote System Upgrades" chapter in the FPGA handbook. I try to program with DE2-115 board. flash memory are on the board, so I'll try it.- Altera_Forum
hi
yes you can make stand alone nios2 system........but you need do add a flash memory or a epcs in your system. you need set the reset vector and exception vector at sopc to cpu starts in your flash memmory.. good luck Franz Wagner - Altera_Forum
Look the "Configuration and Remote System Upgrades" chapter in the FPGA handbook.

Configuration is volatile and FPGAs lose it whenever you turn power off.
If you don't want to load configuration every time with USB programmer (and usually you can't do it when the system has been deployed on the field) you need a non-volatile memory connected to fpga. This can be a serial or parallel flash memory. The common solution is using epcs serial flash devices supplied by Altera itself. - Altera_Forum
Hi,thanks your res.
Hm... When performing NiosII, must a USB cable always be connected? And, every time I put the power supply into the board, do I have to let QuartusII-Programmer to program the board?
