Convert Programming Files

Hi

I created a factory boot image with NIOS processor to reboot FPGA to application from know address and I am trying to make a pof image of the boot image sof (to reside in Page 0 at address 0x0), which will immediately be followed by the hex data file, and then I am setting the application hardware (without NIOS) to Page 1 address 0x400000.

However, whenever I try to use convert programming files, using relative addressing on the hex data, the hex data always gets shoved at the end of the application (i.e. 0x400000 + size of application).

How can I stop this?

Thank you.
