S32k146 Start-upclock configuration

Hi,

In which file is the startup clock configuration handled in the S32K146 microcontroller? If possible, please provide an example of the configuration code.

Thanks

Hi SreejithN,

I didn't see clock configuration changed in startup code:

Note FOPT[LPBOOT] controls the reset value of clock divider of IRC 48 Mhz to feed the Core and platform clocks.

Here is the Default configuration after reset:

I think you can refer to the S32K1 SDK example to initialize the clock module in the main function:
/* Initialize clock module */
status = CLOCK_DRV_Init(&clockMan1_InitConfig0);

Best Regards,
Robin
