Creating pof from sof and two hex - exceeds memory

Thanks. Looking at the map file I can see that when I add the second hex file its placing the nios code after it and thats the reason for memory exceed.

So it seems using the Convert Programming File utility will place a "Relative addressing" hex at location after other hex files (not just after the sof).

Hex Data Nios -- Relative addressing -- <auto>

Hex Data Tiny -- Absolute addressing -- 0x007F0000

Sof Data -- Page_0 -- 0x00000000

This results in the Nios code being placed after 0x7F0000... I cant seem to change the priority in Convert Programming Files...

So the question now becomes:

How do I include two hex files and keep the nios code as relative addressing directly after sof and then add another hex file with absolute addressing after that?
