S32k144 clock source change

[vinaykl]

Hello team,   

            I want to change the system clock source of my current running configuration. I just saw one API "CLOCK_DRV_SetSystemClock()"

            I just want to know how to use this API and what is the use of it. And I just want to know the arguments I need to pass in this.

Thank you

Vinay

Hello danielmartynek,

Thank you for the reply, I am using S32K144_SDK 3.0 SDK

Hi @vinaykl,

You would need to define the two parameters in the code.

Their declaration can be found in clock_S32K1xx.h

You can use the CLOCK_DRV_GetSystemClockSource() and pass the defined struct there first to get the current clock source. Then change it and use it in CLOCK_DRV_SetSystemClock().

However, the SDK 3.0.0 Processor Expert allows creating more clock configurations.

The system clock can be updated using CLOCK_SYS_UpdateConfiguration().
