MPC5744 CLOCK SETUP FAIL

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;

}
