Honored ContributorDEO_Nano as onboard system
Hi Guys,
I am still beginner in FPGA. May i ask some suggestions? Now, i am doing project with DEO_Nano ALTERA Cyclone IV. I use QUARTUS II 10.1 and NIOS II. I want to make my system as onboard system. So, in the future i want to use battery as power source for my DEO_Nano board. Then, my question is: How to make my DEO_Nano don't need to be upload the program again at power-on and don't lose that configuration when the power goes off (battery as power source), but i still can upload new code to the board if i build new code. So, it will be similar with others microcontroller. Thank you so much for your help.5 Replies
Altera_ForumStart a tool called "Flash Programmer" from Eclipse, add your *.sof and *.elf files, the program EPCS device. You will be able to re-configure FPGA over JTAG with your "new code" later if needed.

What's "board memory"? You need an EPCS device to store configuration data for your FPGA. Here is some additional info: http://www.altera.com/literature/hb/cfg/cfg_cf51001.pdf

oh okay,
i mean, when we build SOPC builder what kind of memory should be used, usually i use on chip memory or SDRAM. and then, what's the difference between EPCS and Flash Memory Interface? Thank you. - Altera_Forum
You are the designer and you decide what to use, on-chip RAM, SDRAM, MRAM, etc.
What's Flash Memory Interface? I did not found this one in QSYS.
