Checkboxes are disable, but PLL and FXOSC are enable. Could you please give me more details about what you want to do?

i tried to blink the led for 100ms.

i write the code like below.(use the reference code of example)

void OsIfDelay(uint32 timeoutMs) {

uint32 currentTime = 0u;

uint32 endTime = 0u;

uint32 timeoutCount = 0u;

currentTime = OsIf_GetCounter(OSIF_COUNTER_DUMMY);

timeoutCount = OsIf_MicrosToTicks(timeoutMs * 1000u, OSIF_COUNTER_DUMMY);

while (1) {

// endTime - (start count + currentCount ) = 0

endTime += OsIf_GetElapsed(&currentTime, OSIF_COUNTER_DUMMY);

if (timeoutCount <= endTime) {

break;

}

int main(void) {

/* Write your code here */

/* Initialize the Os */

OsIf_Init(NULL_PTR);

/* Initialize the Mcu */

Mcu_Init(&Mcu_Config);

/* Initialize the Mcu Clock*/

Mcu_InitClock(McuClockSettingConfig_0);

while ( MCU_PLL_LOCKED != Mcu_GetPllStatus() )

{

/* Busy wait until the System PLL is locked */

}

Mcu_DistributePllClock();

Mcu_SetMode(McuModeSettingConf_0);

// timing set

Port_Init(NULL_PTR);

// deactive WatchDog

Dio_WriteChannel(DioConf_DioChannel_WDT_EN,STD_HIGH);

// TURN LED ON/OFF, period : 100ms

while (1) {

Dio_WriteChannel(DioConf_DioChannel_LED1,STD_LOW);

OsIfDelay(100);

Dio_WriteChannel(DioConf_DioChannel_LED1,STD_HIGH);

OsIfDelay(100);

}

return 0;

}

but actually LED blink every 250ms so i think the clock initialize is wrong.

Can you help me make it work?

and i followed the S32K3xxRM.pdf page 963, Reduced speed mode.(Clock configuration)
