Can't build project in the NIOS II IDE

Hi,

i have a DE1 board with Cyclone II EP2C20.. device. I designed my hardware and add all the required components in the SOPC Builder. I use now On-Chip-Memory (later i will use flash for programming). I created new software project in the NIOS II IDE and so on, but i got following error message when i try to build the project in the NIOS II IDE.

"ld: region onchip_memory2_0 is full (Loto_Generator.elf section .text). Region needs to be 35120 bytes larger. Loto_Generator line 0 1259878959171 305

The problem is that i can't use to much size of On-Chip-Memory because my design uses then to much M4K blocks and it doesn't pass the compilation process in the Fitter.

Can anyone please help me? I know i could use SRAM memory instead On-Chip, but is there another option?

Thanks in advance!

Friends, do you set library proprety for example smallC library?

if your setting is ok,I think you must use SRAM or Sdram in board!

Yes i set it. I removed the on-chip memory and use now SRAM, but i got problem when i build the project.

Severity and Description Path Resource Location Creation Time Id

/cygdrive/s/altera/nios2eds/components/altera_hal/HAL/src/alt_main.c undefined reference to `main' Loto_Generator line 165 1260018831078 2

Have any advise what should i do to remove it?

When you use out_memory ,in program you should use main() function not alt_main() function !Do you use it correctly?
