Thanks for the reply Anand.

However, your suggested remedy does not work in my case.

I did some further searching and noticed a thread on here that mentioned the exact same issue I was having (apparently my initial search did not yield this result): https://www.alteraforum.com/forum/showthread.php?t=6499. The suggested fix in it (turn on automatically generating RBF during compilation) solved my issue.

It is very interesting to me that the tool (Quartus) generates the RBF differently when it is commanded to as part of the assembler portion of the compilation versus using the Convert Programming Files utility. The convert programming files RBF output does NOT work, yet the RBF generated during the compilation works perfectly.

Is this a Quartus bug? Or an intended design choice that I apparently don't understand the reasoning behind? Seems to me the RBF image should be the RBF image, yet that doesn't appear to be the case.
