Clock on MCXC243

[ravicha]

Here i attached the code file of MCXC243(48 pin) microcontroller where i m not able to genrate the clock plz anyone give me soution and correct the code

in the given code , code is break in below given function

static inline void CLOCK_SetEr32kClock(uint32_t src)

{

SIM->SOPT1 = ((SIM->SOPT1 & ~SIM_SOPT1_OSC32KSEL_MASK) | SIM_SOPT1_OSC32KSEL(src));

}

hello @Alice_Yang thanks for your, here i have already done this settings for clock

Hello @ravicha 

Do you want to choose System oscillator (OSC32KCLK) as ERCLK32K? If so, you need to configure the external crystal oscillator or an external source. Checking from your code and the Clock Configuration view, it hasn't been configured.

Configuration as below:

Additionally, you need to add an external crystal oscillator to your hardware board.

Hope it helps.

Hello @ravicha 

I recommend that you use the Clock Config Tools inside MCUXpresso IDE for configuration. After finish configuring. It can automatically generate code. It has a user - friendly interface.
