NIOS II QSPI reset vector

I want to boot NIOS II from QSPI on a MAX10.

I am fallowing these documents as a guideline:

Section 5.2.4 from: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/nios2/edh_ed_handbook.pdf

Section 1.5.3 from: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an730.pdf

The point where I run into a problem is on selecting the reset vectors for the NIOS II. In all the examples I have looked at they show the QSPI being listed in the reset vector drop down box. However in mine it is not listed.

I have the "Generic QUAD SPI controller II Intel FPGA IP" populated in platform designer and have even been able to communicate with the QSPI memory from inside my NIOS application.

However, I want to be able to boot from the QSPI. What am I missing to have the QSPI populate as an option in the NIOS II reset vectors.

    Hello,

    It looks you have not connected Nios II Instruction master to 'avl_mem' port of that controller. Hence, it is not appearing there.

    Thank you.
