Super ContributorUnderstood. Some configuration pins can be used as I/O after configuration and for some reason the tool is not seeing that here even though AE5 is not even being used in that way. I was just saying that Y4 (that you mentioned originally) and AE5 are both "DATA0" but for different configuration schemes.
I guess I would try creating a brand new project first just to rule out any settings or database corruption. After that, yes, it could be a bug.
New ContributorHello, sstrell-san.
Your message gave me a hint.
When I looked at the Dual-Purpose Pins setting, I saw that Data[0] was in Dual-Purpose Pins.
This is my first time using the Cyclone 10GX, and in the Flex10K and other Cyclone families that I have used up until now, AS_Data0 and Data[0] were assigned to the same pin, so I assumed they were the same.
When I set DATA[0] to "Use as regular I/O", I was able to compile without errors.
By the way, this is the board we will be using this time.

This board was first released in March 2019, but it seems that the Enpirion power supply IC was discontinued and replaced with a new one, resulting in the current version.
Thanks, hidetaka.
Super ContributorNew ContributorHello, sstrell-san.
This has been resolved for now, so you may close this case.
Personally, I thought it would be better if Quartus would automatically set Data[0] to "Use as regular I/O" when I selected Active Serial in the Configuration scheme.
Thanks, Hidetaka.
Super ContributorI'm not a moderator, but yes, that would make sense to avoid a silly, difficult to diagnose issue like this.
