Simple blink didnt works

[bangjii]

i'm using atmega128 with and without external crystal, i use cavr code, my code (simple blink pb7) running well. Why when i use this board library get hex and upload using khazama there is no blink? already try 3.0 and 2.0 version of megacore and there is no different.

CAVR

#define F_CPU 8000000UL
#include <avr/io.h>
#include <util/delay.h>

int main(void)
{
	DDRB |= (1 << PB7);   // PB7 output

	while (1)
	{
		PORTB ^= (1 << PB7); // toggle LED
		_delay_ms(500);
	}
}

Arduino

void setup() {
  // put your setup code here, to run once:
  pinMode(15, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(15, HIGH);
  delay(500);
  digitalWrite(15, LOW);
  delay(500);
}

FYI, if you want to control a pin, you can either use digital pin xx or even better, pin macros, PIN_PB7.

But I can't reproduce your issue. I have an ATmega64 board here, and when I flash the Arduino program you have provided toggles the PB7 twice a second. Are you sure the program is actually uploaded? I have no experience with Khazama, and MegaCore doesn't support it out of the box either.

BTW did you know you can use your traditional "C-style" program directly in Arduino IDE? Just remove setup() and loop() and use int main() instead.
