This is what I have been doing this whole day, and again just now after reading your post and it worked. Connections were fine, re-generated bsp, rebuilt my project and it worked.
On a side note, is there something I could be doing wrong where I do the same thing over and over again for hours yielding the same results until eventually things work? For example, the problem I had today. When I first ran into this first thing I did was re-generate the bsp and updated my project. Then updated quartus, and then start over from scratch. Following the same steps each time. It seems like whenever I try to create an SOPC I end up doing it repeatedly for what seems like hours. Continue with this for hours. My steps are exactly the same, I've taken screenshots and recorded myself performing the necessary steps.
