NIOSII fails to upload .EFI with SDRAM controller

Hello; 

I am trying to get my hands on NIOSII with SDRAM controller. 

I already done some tutorials and created simple system in qsys (without sdram controller) 

Everything runs as intended, i can control PIO's (LED and switches) without any problem. 

But as soon as I add SDRAM controller the system fail in uploading the .elf file on NIOSII. 

 

I run NIOSII/s; Reset and exception vector memory: on chip memory;  

Can you please take a look at my configuration, what do I do wrong? 

 

 

Here is my testcode(reading switches, assign value to LEDs): 

# include <stdio.h># include "system.h"# include "altera_avalon_pio_regs.h" int main() { int count=0; while (1) { count=IORD_ALTERA_AVALON_PIO_DATA(SW_BASE)/2; IOWR_ALTERA_AVALON_PIO_DATA(LED_BASE,count); } return 0; }  

thank you.
