Hi Friends

I'm Starter in Atmel ARM Programming. I Write a simple Project, in this project I turn On 3 LEDs Step by Step, at the end I turn off these LEDs. now I have problem with Machine Cycle, My Project Work normally but after Several Second my Micro Reset and Restart Again, I think after several Minute My Micro Complete machine Cycle and Restart Again.

My question is, how do I can reset Machine Cycle at the end of my Project Loop?

this is my Project Source:

#include <AT91SAM7s256.H> /* AT91SAMT7S64 definitions */

int n;
void delay(void);

int main (void)
{

*AT91C_PIOA_PER = 0xFFFFFFFF; // Set in PIO mode
*AT91C_PIOA_OER = 0xFFFFFFFF; // Configure in Output
*AT91C_PIOA_OWER = 0xFFFFFFFF;


*AT91C_PIOA_SODR = 0x00000001 ;
delay();
*AT91C_PIOA_SODR = 0x00000040 ;
delay();
*AT91C_PIOA_SODR = 0x00001000 ;
delay();
*AT91C_PIOA_CODR = 0x00001000 ;
delay();
*AT91C_PIOA_CODR = 0x00000040 ;
delay();
*AT91C_PIOA_CODR = 0x00000001 ;
delay();

}
void delay (void){
for (n=0; n<2500; n++);
}

I Use 18.423 MHz Crystal.

You shouldn't exit the main() function. It doesn't go anywhere you want it to go.

Put a "while(1);" at the end for it to spin in an infinite loop.

thanks for answer. but if I use your way, I had just one cycle.

I use while(1) for all of my Instruction, but after several second reset Program between my cycle.

I change the delay time (100) and help me invisible reset time.

Your English is very tortured.

What do you want the code to do? Run repeatedly? Reset periodically?

Want it to cycle the GPIO pins continuously, then :

while(1)
{
*AT91C_PIOA_SODR = 0x00000001 ;
delay();
*AT91C_PIOA_SODR = 0x00000040 ;
delay();
*AT91C_PIOA_SODR = 0x00001000 ;
delay();
*AT91C_PIOA_CODR = 0x00001000 ;
delay();
*AT91C_PIOA_CODR = 0x00000040 ;
delay();
*AT91C_PIOA_CODR = 0x00000001 ;
delay();
}
