I can't printf

I&#39;ve implemented a simple system with SOPC builder consisting of cpu, onchip memory, jtag_uart and some pios. With this system I can&#39;t run simple code like template:# include <stdio.h>

int main(){

printf("Hello from Nios II!\n");

return 0;}

I&#39;ve set syslib properties-program memory to onchip memory and stds to jtag_uart. I&#39;ve tried also small C library but still it doesn&#39;t work.

If you guess some reason, please give me some tips.

    Look at the Reducing Code Footprint section in Chapter 4 of the Nios II Software Developer&#39;s Handbook. You should be able to get the example above below 4k
