Program crash after few running minutes Topic is solved

Hi all,

By trying to help an member "RTOSman" you can see here: http://forum.chibios.org/phpbb/viewtopic.php?f=21&t=3155

I made a few test and here is my configuration:
- ChibiOS 3.0.4
- Nucléo F401 RE board

The code juste blink the on board LED.

Code: Select all

  #include "ch.h"
  #include "hal.h"
  
  /*
   * LED blinker thread, times are in milliseconds.
   */
  static THD_WORKING_AREA(waThread1, 128);
  static THD_FUNCTION(Thread1, arg){
  
      uint32_t time = ST2MS(chVTGetSystemTime());
  
      (void)arg;
      chRegSetThreadName("blinker");
      
      while (true){
          palTogglePad(GPIOA, GPIOA_LED_GREEN);
          time += 1000;
          chThdSleepUntil(MS2ST(time));
      }
  }
  
  /*
   * Application entry point.
   */
  int main(void){
      /*
      * System initializations.
      * - HAL initialization, this also initializes the configured device drivers
      *   and performs the board-specific initializations.
      * - Kernel initialization, the main() function becomes a thread and the
      *   RTOS is active.
      */
      halInit();
      chSysInit();
  
      /*
      * Creates the blinker thread.
      */
      chThdCreateStatic(waThread1, sizeof(waThread1), NORMALPRIO, Thread1, NULL);
  
      /*
      * Normal main() thread activity, in this demo it does nothing except
      * sleeping in a loop.
      */
      while (true){
          chThdSleepMilliseconds(1);
      }
  }                                                                                                               

As a result, the on board led blink but after 7 minutes of running it turn off and stop blink.
Did I made miss something?
How can I used the debugger to catch such event?

Cheers,

Hi,

How can I used the debugger to catch such event?

Thanks, I'm going to try to locate the problem. But in géneral, what can cause such problem?

cheers,

Theo.

Sorry, all is explain in the debugger guide.

Thanks.

Hi,

I will spare you a debug session, this time only

Look at your loop and compare with the example here: http://www.chibios.org/dokuwiki/doku.ph ... :kb:timing

Hint, it is not equivalent.

Hi Giovanni,

Thank you for you help and you hint .

I did not use the MS2ST function properly. While the system tick was under the value I passed to the chThdSleepUntil function every thing was ok.
But this was not true every time so that why the program stopped when this condition was false.

Thank you,

cheers, Theo.
