ContributorCyclone 10 GX dev kit, which signal can I use to reset a NIOS?
I've had a look at the Cyclone 10 GX dev kit user manual and schematics but it's not clear if the board provides a signal to the C10 that will drive the NIOS platform reset input correctly. Any suggestions?
I suppose I could code up a pulse generator that runs after configuration but I was hoping for something official.
Edit - found pin AC12 has a likely sounding assignment of fpga_resetn which seems to come from a MAX10. Any clues as to what the MAX10 does with it?

Hi,
you find a brief description in user manual. Check S13 function.- Oliver_I_Sedlacek
I found that, but that's a manual reset. How to I give my NIOS a post configuration automatic 'power on' style reset?
wwanalim_intelHi,
Thank you for reaching us.
You can enable Include cpu_resetrequest, and use a PIO IP as input into cpu_resetrequest.
Or, with the connection below made, use the debug module to reset the core only.
If the same signal is connected to other IP's reset, you can extend to full system reset.
You also can refer below link about this.

I am sorry for the picture above. Below I reattached the picture.

This seems to be a way to add more reset (sink) inputs. I'm looking for a reset source to drive the reset input after FPGA configuration.

I would suggest for you to connect a PIO IP to another push-button and feed it into the cpu_resetrequest.

That's not what I'm after. A manual reset isn't an alternative to a configuration completion reset.
BTW it's taken me an hour to get to the point of replying to this thread because the forum software is so flaky it wouldn't put up this box for me to reply. I've tried several browsers and several login in cycles. For a billion dollar corporation this is very, very poor.

It is unfortunate from our side that our suggestion is different from what you prefer. Can you elaborate more about the manual reset? We quite confused on that part.
