How does one determine the address space of Nios II program in MAX 10 UFM when using .pof file for internal configuration?

In the current system, the Nios II reset vector is set to On-Chip Flash. After power up the Nios II program is loaded into an external DDR2 RAM from the flash and executes from there. For Max 10 inte...

​There are a few problems with that approach. Here is a screenshot of our .map file. Below it is the screenshot of the Qsys system's flash memory component settings.

The address space in the .map file seems to encompass the entire flash memory. The Nios .hex file is only 282kB. This is not so big that it should fill the entire flash memory.

Therefore, it is concluded that the .map file does not give the information we are looking for.

The address space information in the .map file includes the ICB which starts at 0x0. This is not even present in the Qsys settings where we can see that the UFM sector 1 starts at 0x0. It is not clear why such discrepancy exists.

It is not clear what part of UFM can be used by us in our C program to store settings for the program.
