MPC5744 CLOCK SETUP FAIL

[acechongya]

Hi,

        I used mbd generate code, but startup fail.  cpu dead in function of CLOCK_DRV_Init .

my hardware is DEVKIT-MPC5744P. can you tell some reasons ?

status_t CLOCK_DRV_Init(clock_manager_user_config_t const * config)

{

    status_t result = STATUS_SUCCESS;

    DEV_ASSERT(config != NULL);

    /* Clears peripheral clock gating and all clock sources in all power modes.

     * Only an IRC type clock source is enabled and set as system clock source. */

    result = CLOCK_SYS_Reset();

    if (STATUS_SUCCESS == result)

    {

        /* Configure clock sources. */

        result = CLOCK_SYS_ConfigureCgmcs(config);

        if (STATUS_SUCCESS == result)

        {

            /* Configure peripheral clock gating, system clock source

             * and clock sources in all power modes. */

            result = CLOCK_SYS_ConfigureMcMe(config);

            if (STATUS_SUCCESS == result)

            {

                /* Configure peripheral clocks. */

                result = CLOCK_SYS_ConfigureCgm(config);

#if FEATURE_HAS_SDPLL_CLK

                if (STATUS_SUCCESS == result)

                {

                    /* Configure peripheral clocks. */

                    result = CLOCK_SYS_ConfigureSdpll(config);

                    if (STATUS_SUCCESS == result)

{

CLOCK_SYS_SetCMU(config);

}

                }

#else

                if (STATUS_SUCCESS == result)

{

CLOCK_SYS_SetCMU(config);

}

#endif

            }

        }

    }

    /* Calculate frequencies of clock sources and cache these values. This function is not called at runtime */

    CLOCK_SYS_CalculateFrequenciesOfClockSources(false);

#if (defined(PRAMC_0) || defined(PRAMC_1) || defined(PRAMC_2))

    uint32_t systemFrequency = 0U;

    (void)CLOCK_DRV_GetFreq(SCS_CLK, &systemFrequency);

    if (systemFrequency >= FEATURE_FT_DIS_CHECK_SYSTEM_FREQUENCY)

    {

#if defined(PRAMC_0)

PRAMC_EnableFlowThrough(PRAMC_0, false);

#endif

#if defined(PRAMC_1)

PRAMC_EnableFlowThrough(PRAMC_1, false);

#endif

#if defined(PRAMC_2)

PRAMC_EnableFlowThrough(PRAMC_2, false);

#endif

    }

    else

    {

#if defined(PRAMC_0)

PRAMC_EnableFlowThrough(PRAMC_0, true);

#endif

#if defined(PRAMC_1)

PRAMC_EnableFlowThrough(PRAMC_1, true);

#endif

#if defined(PRAMC_2)

PRAMC_EnableFlowThrough(PRAMC_2, true);

#endif

    }

#endif

    return result;

}
