fsl_clock_manager.c has changed in SDKV1.2.0

DaveTonyCook — Wed, 03 Jun 2015 12:05:46 GMT

The SDK V1.2.0 has changed significantly from V1.1.0 in particular I am interested to know what changes / bugs have been fixed in fls_clock_manager.c in v1.2.0 of the SDK

What do I need to be aware of if I want to copy this file into my v1.1.0 based project.

Thanks

Hello Dave,

yes, there are some changes for fsl_clock_manager.c in KSDK1.1 and KSDK1.2

Because of structure change for KSDK1.2 were added definitions for macro for clock manager critical section,

#if (USE_RTOS)
    mutex_t g_clockLock;
    #define CLOCK_SYS_LOCK_INIT()    OSA_MutexCreate(&g_clockLock)
    #define CLOCK_SYS_LOCK()         OSA_MutexLock(&g_clockLock, OSA_WAIT_FOREVER)
    #define CLOCK_SYS_UNLOCK()       OSA_MutexUnlock(&g_clockLock)
    #define CLOCK_SYS_LOCK_DEINIT()  OSA_MutexDestroy(&g_clockLock)
#else
    #define CLOCK_SYS_LOCK_INIT()    do {}while(0)
    #define CLOCK_SYS_LOCK()         do {}while(0)
    #define CLOCK_SYS_UNLOCK()       do {}while(0)
    #define CLOCK_SYS_LOCK_DEINIT()  do {}while(0)
#endif

added system timer

#if FSL_FEATURE_SYSTICK_HAS_EXT_REF
uint32_t CLOCK_SYS_GetSystickFreq(void)
{
    /* Use external reference clock. */
    if (!(SysTick->CTRL & SysTick_CTRL_CLKSOURCE_Msk))
    {
#if FSL_FEATURE_SYSTICK_EXT_REF_CORE_DIV
        return CLOCK_SYS_GetCoreClockFreq() / FSL_FEATURE_SYSTICK_EXT_REF_CORE_DIV;
#else
        return 0U;
#endif
    }
    else // Use core clock.
    {
        return CLOCK_SYS_GetCoreClockFreq();
    }
}
#endif

different structure of FBE mode

CLOCK_HAL_SetFbeMode(MCG,

oscsel,

targetConfig->frdiv,

targetConfig->dmx32,

targetConfig->drs,

fllStableDelay,

&outClkFreq);

added new functionality for MCGIRCLK

    if (targetConfig->irclkEnable)
    {
        if (kMcgIrcFast == targetConfig->ircs)
        {
            /* Update FCRDIV if necessary. */
            CLOCK_HAL_UpdateFastClkInternalRefDiv(MCG, targetConfig->fcrdiv);
        }
        CLOCK_HAL_SetInternalRefClkMode(MCG, targetConfig->ircs);
        while (targetConfig->ircs != CLOCK_HAL_GetInternalRefClkMode(MCG)) {}
    }

and adding new functions for initialization OSC according to configuration, deinitialization, setting OSCERCLK for clock transition, initialization RTC OSC and its deinitialization.

More easier way than migrate project from KSDK1.1 to KSDK1.2 is create new one, but you can inspire by this general guide (for migration project), but there is no clock settings.

In additional, here could be also very useful discussion for you

Clock configuration with KDS3.0/KSDK1.2.0

Please, what do you use for MCU?

I hope it helps you,

Best Regards,

Iva

We are using the K24F1M0 144 pin device

Hello Dave Tony Cook,

thank you for your response.

You probably have on mind K24FN1M0. KSDK 1.2 supports MK24FN1M0VDC12, MK24FN1M0VLL12, MK24FN1M0VLQ12.

So I recommend you use always the newest version.

I hope this helps,

Iva
