[MSP430F169] problem of quartz starting

Hi everydoby,

I was a newbies in the PSM programming.

I have a problem with starting of MSP430, when I launch my application (just ‘‘while’’ buckle), the quartz dont start. I work with the debugger mode, the tool is MSP-FET430UIF, the program loading is ok. But the don’t start, in mode ‘‘Run the program in the debugger’’, the MSP apply to the quartz a 22 Hz frequency (3.3V voltage) with dutty cycle at 82%.

If I use ‘‘Step into the current step point’’, the quartz doesn’t have the 3.3V voltage to running.

The OSCFault flag don’t set.

My program :

void initClockModule(){

unsigned int i;

//Basic clock module

BCSCTL1 |= 0x00; // XT2 on, High frequecy mode

do

{

IFG1 &= ~OFIFG; // Clear OSCFault flag

for (i = 0xFF; i > 0; i–); // Time for flag to set

}

while ((IFG1 & OFIFG)); // OSCFault flag still set?

//Configuration des Clocks internes

BCSCTL2 |= SELM_2; // la source du master clock c’est le quartz XT2

BCSCTL2 |= DIVM_0; // pas de prédivision

BCSCTL2 |= SELS ; // la source de SMCLK est le quartz sur XT2

BCSCTL2 |= DIVS_0; // division à regler en vue de la vitesse du timer (par 1)

WDTCTL = WDTPW + WDTHOLD; // Stop WDT

}

Best regards,

It’s good, I find my problem, in the line :

BCSCTL1 |= 0x00; // XT2 on, High frequecy mode

It’s doesn’t

‘‘BCSCTL1 |= 0x00;’’

but ’

‘BCSCTL1 = 0x00;’’

Thanks a lot and bye !
