Hello all,

I am using following code to shutdown the ARM7 AT91Sam7128 chip. If i do not give much delay(i.e. more then 1sec lets say) and apply the power source again. The microcontroller seems to be halt some how. If any one can help me to get through this problem i will be very grateful.

(void) AT91F_RSTSetMode( AT91C_BASE_RSTC, 0);
// Sets the a pin low, for shutdown, this pin disables the vcc source
GPIOOutputPortLow(AT91GPIO_SHUTDOWN);
//
while(1)
{
TimersWatchdogReset();
}

Regards
Dani
