My ATmega64 is not functioning properly after getting programmed completely

[adityaheroes]

Hey! I am facing a weird problem from my ATmega64. The IC is getting programmed but the code or for that matter any code is not working on it.. that includes even toggling any pin on the board.:-(. I want suggestions asap so that i can correct in time. Thank you in advance.

Post your circuit, code, hex file, cof file and proteus file if you have.

I have done the coding in CodeVisionAVR. I have the pcb board in eagle and basic hex file which says "PORTA =1". Although it was only for testing purposes.. even though it was programmed using sinaprog still it was not working and it was not just the PORTA, none of the PORTs of the IC are working. If i mail u these will it be alright?

Maybe try some different code because PORTA =1 just enables the pullup of port A bit 0

This code turns all ports to outputs and blinks them but be careful if you have anything connected to the pins when you use them as outputs.

#include <mega64.h>
#include <delay.h>

void main(void)
{

DDRA=0xff;
DDRB=0xff;
DDRC=0xff;
DDRD=0xff;
DDRE=0xff;
DDRF=0xff;
DDRG=0x1f;

while (1)
      {
		PORTA ^= 0xff;
		PORTB ^= 0xff;
		PORTC ^= 0xff;
		PORTD ^= 0xff;
		PORTE ^= 0xff;
		PORTF ^= 0xff;
		PORTG ^= 0x1f;	  
	
		delay_ms(500);
      }
}
