Debugging an avr atmega 8 microcontroller code

[Himadri Bandyopadhyay]

Please help me with debugging the code
The error message is
exit code 2

#include"at8ports.h"
#include<avr/io.h>
#include<util/delay.h>
void init_settings()
{
   DDRB_OUT(0);   
   DDRB_OUT(1);   
   DDRB_OUT(2);   
   DDRB_OUT(3);   
   DDRB_OUT(4);   
 
   DDRB_OUT(5); 
   DDRB_OUT(6); 
 
   DDRB_OUT(7);   
     }

int main(void)
{

  init_settings();
  While(1)
  {
  PORTB=0xoo;
    _delay_ms(50);
    PORTB=0x01;
    _delay_ms(50);
    PORTB=0x02;
    _delay_ms(50);
    PORTB=0x04;
    _delay_ms(50);
    PORTB=0x08;
    _delay_ms(50);
    PORTB=0x10;
    _delay_ms(50);
    PORTB=0x20;
    _delay_ms(50);
    PORTB=0x40;
    _delay_ms(50);
    PORTB=0x80;
    _delay_ms(50);
    }
   }

the led pattern on the bread board will be
00000000
00000001
00000010
00000100
00001000
00010000
and so on...

What compiler are you using?

What does the message "Exit code 2" mean? Look up the compiler documentation.

When you post code, surround it with (CODE) and (/CODE) tags (use square brackets instead of parentheses). This makes it appear in a monospaced font with whitespace preserved, so things line up.

PORTB=0xoo;

Do you mean 0x00? (or just plain old 0)
