How to get virtual UFM included into pof.map

v18.1 tools, Nios II/e device: 10M16DCU324

We're executing from flash.

Summary.html shows larger onchip_flash_0 space. mem_init_generate or conversion to pof file: conversion.map file still shows UFM as UFM0+UFM1 size, (ie does not show UFM space increased by additional virtual-UFM from CFM).

...we are not initializing memory since we're running directly from flash.

We need expanded .text base of UFM0+UFM1 + CFM2 (at minimum) to allow our larger code size (perhaps 50kB).

Appreciate insight. Something is clearly missing!!!

What gives?

    The issue was incorrect device on the HW: a 10M16DCU324 was installed while a 10M16DAU324 or 10M16DFU324 should have been installed. The 'DC' does not support virtual-UFM in the CFM sectors.

    Hi,

    You will need to set your Quartus design to Single Uncompressed Image which will make the space available in On Chip Flash IP.
