DE0-Nano, Configuration via Passive Serial

Good day,

I've already bought a bit DE1 and fully satisfied with it.

Now I wanted to order DE0-Nano for my project.

It is configured using "Passive Serial" means PIC32.

In the circuit diagram of DE0-Nano I think unfortunately

no information where the "DATA0" lead "CONF_DONE", "DCLK",

"nSTATUS" and "nCONFIG".

Is it possible to configure DE0-Nano via PS?

Dmitriy

p.S. sorry for my english...

    Hi Dmitriy.

    I don't one one, but since it has a EP3C16, it looks like it's probably setup as a Active Serial configuration.

    The Clock, Data0, nSTATUS and nCONFIG should be all available, either at the EP3C16 or through pull-ups, but the mode select pins, may be hard wired on the board.

    The only way to find out is to get a schematic, but I couldn't find one the Terasic site.

    Hi,

    I have the schematic. It is at DE0 Nano-CDROM.

    There is no configuration PROM and USB-Blaster in the schematic.

    I can not understand if "DE0 nano" can be configured via AS.

    The configuration pins are on page 8 (bottom right), more is not there.

    I need the information of where these pins are connected.
