I think I can help. Check out my written solution on my own post which had the same problem as you're having. Since you are using the DE1, not Cyclone V Development Kit, I bet it's the same problem as me. I was using the DE10-Nano.
Let me know if I can clarify anything in my solution post for you.
[Edit a few hours later: I noticed in your post that I misread, and that you did in fact tailor the process for your DE1-SoC kit. My fix might not be much use then. Did you you do all three steps? Hand-off, qts_filter, and the config?]
And just to be clear, in my post I linked above, I mention the Bare Metal User Guide, but go ahead and completely ignore that. What I typed as my solution applies to the SoCEDS example you linked as well. I reference this example in my post as well.
