How to load program to SSRAM

Hello !

I have a custom NIOS II system with STRATIX II and SSRAM.

I am doing this steps for load and start my system:

( All program sections placed in SSRAM)

1. Nios2 compilator create *.elf

2. I convert *.elf to *.bin with

"nios2-elf-objcopy.exe 1.elf -O binary --set-start 0 1.bin"

3. I init SSRAM with my *.bin

4. I reset NIOS.

In this case working only simple program ( printing constant string to LCD for example).

System crash when i writing C-code with variables.

How must I load *.elf to SSRAM correctly?

Thanks.

Sorry for my English
