Problems with os-less

[aduss95]

Hello,
I am trying to launch a GPT demo on STM32f429zi, using os-less. I make the project's makefile is going through successfully,
initialization of the timers too, but exit from gptStartContinuous function (& GPTD4, 5000) caused the program to stop working correctly.
Someone has similar problem or could give me some advice?

What is "stopped working correctly"?

Does it enter the callback?

Yes it isn't enter to callback

Stop the program and see where it is stuck. If you need advice then provide info.

so i try explain it,

this is my callback function :

// GPT4 callback.
static void gpt4cb(GPTDriver *gptp) {
(void)gptp;
palSetPad(GPIOB, 7);
osalSysLockFromISR();
gptStartOneShotI(&GPTD3, 1000); /* 0.1 second pulse.*/
osalSysUnlockFromISR();
}
// GPT3 callback.
static void gpt3cb(GPTDriver *gptp) {

(void)gptp;
palClearPad(GPIOB, 7);
}

so its my piece of code
//Initializes the GPT drivers 4 and 3.
gptStart(&GPTD4, &gpt4cfg);
gptPolledDelay(&GPTD4, 10); /* Small delay.*/
gptStart(&GPTD3, &gpt3cfg);
gptPolledDelay(&GPTD3, 10); /* Small delay.*/

while(1){
palSetPad(GPIOB, 0);
gptStartContinuous(&GPTD4, 5000);
osalThreadSleepMilliseconds(5000);
gptStopTimer(&GPTD4);
palClearPad(GPIOB, 0);
gptStartContinuous(&GPTD4, 5000);
osalThreadSleepMilliseconds(5000);
gptStopTimer(&GPTD4);
}
while debugging through this code step by step, gptStartContinuous(&GPTD4, 5000) this function have done, but callback functions didn't call out .
Then it execute the next function and doesn't go to gptSTOP
