I have some nano clones that I have been trying to test but I kept getting infinite upload times.
Apparently this is a common problem with nanos but no singular solution exists, so I spent a good couple hours googling and getting frustrated. Especially since I was able to upload a sketch fine initially, and then it suddenly stopped working.
I am pretty sure now the issue is with the "updates" that popped up in the IDE. I installed them without really thinking about it. When I went back and reinstalled the clean IDE it worked fine.
Sorry if this is the wrong forum, I just felt like I needed to post this.
