OSA_TimeDelay hanging on TWR-K64F120M

[kalden_srcinc]

Calling OSA_TimeDelay on the TWR-K64F120M is hanging my application.  If I step through with the debugger it gets into OSA_TimeGetMsec and never returns.  Is there something special that needs to be initialized for these functions to work, or is this possibly a bug in the board specific files for this demo board?

Thanks

Hi Kevin,

Which version of KSDK do you use ?

And there is nothing to be initialized , it can directly use , like this :

If you still can not use it ,you can send your project to me or tell me how to recurrence your appearance.

KSDK 1.1.0.

I'll strip my project down into a simple example case and post it here.  Just to clarify though, the function takes milliseconds, correct?

Hi Kevin,

Try following please and let us know what happens.

#if 1		/* //DES 1=test, 0=default code */
CLOCK_SYS_EnableLptimerClock(NULL);								/* //DES enable clock to LPTMR0 module */
LPTMR_HAL_SetFreeRunningCmd(LPTMR0, 1);							/* //DES set LPTMR0 to free running */
LPTMR_HAL_SetPrescalerClockSourceMode(LPTMR0, kPortLPOClock);		/* //DES set LPTMR0 clock source to LPO */
LPTMR_HAL_Enable(LPTMR0_BASE);									/* //DES enable LPTMR0 module */

#endif

  RTC_DRV_SetDatetime(FSL_RTCTIMER1, &datetime_des);

  /* For example: for(;;) { } */

  while(1) {

	OSA_TimeDelay(1000/2);		/* //DES test function that uses the lptmr. */
	PORT_HAL_SetHighGlobalPinCtrl(PORTB_BASE,21, 0x100);
	counter++;
	counter++;
	counter++;
	counter++;
	if(!(counter % 0x10000)) {
		RTC_DRV_GetDatetime(FSL_RTCTIMER1, &datetime_now);
	}

  }

I just needed to add #include "fsl_clock_manager.h".

Yes this seems to have fixed the problem.  Is this code that should have been included in hardware_init  ?

Hi Kevin,

Glad it is working for you.

Not certain if it should have been included so need time to dig into that.  At very least I would have thought the osa1:fsl_os_abstraction would have GUI to configure the lptmr.

I should clarify that I am not using KDS.  This is all built from the command line.

what do I need to link to to get "CLOCK_SYS_EnableLptimerClock".  I am getting undefined reference.
