Problem executing program even after successfully burning in ATMega32A MCU using ASM

[dsk2858]

Hi ,

I am using ATmega32A MCU and AVR Studio-4 .written a assembly program to glow the leds connected in PORTD.
I simulated it using AVR Studios-4 simulator ,its executing exactly as the program.

[COLOR="#FF0000"].INCLUDE "M32DEF.INC"
.ORG 0x0000
RJMP MAIN
MAIN: 	LDI R16,$FF
		LDI R17,$00
		OUT DDRD,R16
		OUT PORTD,R17
END:	RJMP END[/COLOR]

Then i burned the generated .hex file in to the ATmega32A it was no getting executing.

I tested the MCU it is fine by writing the same code using C-Language .

[COLOR="#FF0000"]#include<avr/io.h>

main()
{
DDRD=0XFF;
PORTD=0X00;
}[/COLOR]

Help me to solve the problem.
thank u

Sorry... But then I met C-Language, does not remember anything from asm... hehehe... :lol:
Please, try this ( I dont have asm compiler/ I using linux in this time):

.INCLUDE "M32DEF.INC"
.ORG 0
	RJMP	MAIN
MAIN:
	LDI	R16,$FF		; Load 255 in R16
	OUT	DDRD,R16	; Copy to DDRD and set output
	LDI	R16,0xAA	; Load 0 to R16
	OUT	PORTD,R16	; Copy to PORTD 0s
END:
	RJMP	END		; Goto End

This code put only all pins in low.

To flip and flop, you need a delay time function.
