Nios II Console only displays the first printf statement

As the title says, I am trying to print some values, and the Nios II Console only prints the first printf statement.

#include <stdio.h># include <alt_types.h># include <io.h># include <system.h># include <string.h>
int main()
{
        unsigned long *THE_ADDRESS;
         THE_ADDRESS = (unsigned long *)ADDRESS_SPAN_EXTENDER_0_WINDOWED_SLAVE_BASE;
         printf("Debugging");
         printf("Reading from Address: %p", THE_ADDRESS);
         IOWR_32DIRECT(THE_ADDRESS,0, 0);
         int i = 0;
         printf("value: %x", IORD_32DIRECT(THE_ADDRESS, i));
         while(i<20)
         {
             printf("value: %x", IORD_32DIRECT(THE_ADDRESS, i));
             i++;
         }
         return 0;
}
