I'm using AVR Studio 4, Dragon prog'r and my Uno_328P to load debug & run blinky.c

Code:

/* blinky.c source code */
 
#include <avr/io.h>
#include <util/delay.h>

#define BAUD_RATE 19200
UBRR0L = (uint8_t)(F_CPU/(BAUD_RATE*16L)-1);
UBRR0H = (F_CPU/(BAUD_RATE*16L)-1) >> 8;
UCSR0B = (1<<RXEN0) | (1<<TXEN0);
UCSR0C = (1<<UCSZ00) | (1<<UCSZ01);
 
int main (void)
{
  unsigned char counter;
  /* set PORTB for output*/
  DDRB = 0xFF;
 
  while (1)
    {
      /* set PORTB.2 high */
      PORTB = 0xFF;
 
      /* wait (10 * 120000) cycles = wait 1200000 cycles */
      counter = 0;
      while (counter != 50)
{
  /* wait (30000 x 4) cycles = wait 120000 cycles */
  _delay_loop_2(30000);
  counter++;
}
 
      /* set PORTB.2 low */
      PORTB = 0x00;
 
      /* wait (10 * 120000) cycles = wait 1200000 cycles */
      counter = 0;
      while (counter != 50)
{
  /* wait (30000 x 4) cycles = wait 120000 cycles */
  _delay_loop_2(30000);
  counter++;
}
    }
 
  return 1;
}

I confirmed that the Uno is connected OK by reading back the device signature and Vtarget=3.6v in AVR Studio.
The device is erased and ready to program. When I try to Build the program it gives;

Code:

I don't understand the error it gives.
Suggestions are appreciated.
Thanks!

The problem is that your code didn't compile.
It didn't compile because your make didn't provide a compile command. You can see this here:

mmcu=atmega328p -Wall -gdwarf-2 -Os -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -MD -MP -MT blinky01.o -MF dep/blinky01.o.d  -c  ../blinky01.c
/usr/bin/sh: -Wall: command not found

It should be something like

[The compiler I user] mmcu=atmega328p -Wall -gdwarf-2 -Os -std=gnu99 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -MD -MP -MT blinky01.o -MF dep/blinky01.o.d  -c  ../blinky01.c
/usr/bin/sh: -Wall: command not found

I'm not sure why he is complaining about Wall and not mmcu as "command not found" but it is clear your compiler is missing

Thanks for your reply. I needed to set the path to the WINAVR dir. It was missing in the /Project/Config. Options/Custom Options box.
The Use ext. AVR chain box needs to be unchecked as well.
Thanks!
