What is in main.c line 39? Where do you see program is halted?

I am trying to debug software timer using freeRTOS main.c mentioned below .

But I feel that it may not problem of any source file.beacause I have check with LED blink code also but same problem so.

main.c

/*! header files */

#include ''stm32f4xx.h''

#include ''FreeRTOS.h''

#include ''timers.h''

#include <math.h>

#include <stdio.h>

#include <stdlib.h>

typedef void * xTimerHandle;

/*! Timer Expirecounter */

long lExpireCounters = 0 ;

/*! Handle to xtimerAPIs */

xTimerHandle xTimer;

/*!

* callback function

* count the number of times the

* associated timer expires, and stop the timer once the timer has expired

* 10 times.

*/

void vTimerCallback( xTimerHandle pxTimer )

{

const long MaxExpiryCount = 10 ; /*! Maximum Expiry ount */

/*! Increment the number of times that Timer has expired. */

lExpireCounters += 1;

/*! If the timer has expired 10 times then stop it from running.*/

if( lExpireCounters == MaxExpiryCount )

{

xTimerStop( pxTimer, 0 ); /*! Timer Stop if Condition satisfied */

}

int main( void )

{

long x=1;

// line no 39

/*! Create timer */

xTimer = xTimerCreate( ''Timer'' , /*! Name for timer */

(100) , /*! The timer period in ticks.(1 ticks = 1ms) */

pdTRUE , /*! The timers will auto-reload themselves when they expire. */

(void *) x , /*! timer a unique id */

vTimerCallback /*! callback fuction ,called when Timer get expires */

);

if( xTimer == NULL )

{

printf(''Timer not created'');

/*! The timer was not created. */

}

else

{

/*! Start the timer. */

if( xTimerStart ( xTimer, 0 ) != pdPASS )

{

/* The timer could not be set into the Active state.*/

}

else

{

printf(''Timer start sucessfully\n'');

}

/*! Task scheduling started */

vTaskStartScheduler();

while (1);

}

Hello Manish,

Are you using F3 or F4? I see in the code:

#include ''stm32f4xx.h''

Another question: do you have same issue if FreeRTOS isn't used? -Mayla-

Now more of a question is why you thought that f4 code will work fine on f3 without even changing a header file?

Yes, and if you have system_stm32f4xx.c, and call SystemInit() it's never going to leave, and consequently not get to main()

Review carefully how you have ported the project to the different processor and board.
