Yes, I did set my NiosV reset vector to QSPI Flash.

Ah yes, now I remember, I did follow that link, and most of it applies, except for the .jic creation. I am only putting my app.hex in flash (not my fpga bitstream), and .jic didnt seem to have any support for Max10 or my N25Q512A device.

So I tried to create a .pof instead, which is not covered in the documentation.
