cycloneive boot from sd card

I build the nios II core with qsys.

I build boot code with eclipse.

I program whit NIOS flas programmer.

It writes the sof file (fpga) and elf file to eeprom epcs16.

At power up the boot is copied from epcs16 to sdram at address 0x02000000.

The boot can write the sdram but only at adress 0x02000000 + BIGOFFSET. (0x02000000 is the base address sdram)

If i write sdram 0x02000000 + 0x100 (for example) the NIOS II processor crash.

I build the app code with eclipse.

the problem is that I can not write the .exception (app code) section to an address different from 0x020000xx.
