S32K311 MAKE THE CORE CLOCK AS THE SYSTEM CLOCK

[hajianik]

Hi, 

I have a hard time to make the core clock as the system clock for s32k10-11 series.

I know default system clock is FIRC of 48 MHz however I want to  change the system clock to the core clock of 120MHZ.

Thanks,

Hi Daniel,

Thanks for your response.

My question is not how to configure the core clock to be 120mhz but rather to designate the core clock to be the system clock.

I say that because on power up the system clock seems to be IFRC , HOWEVER IN MY CODE I CALLED THE FUNCTION:

" Clock_Ip_Init(Clock_Ip_aClockConfig);" and that does the trick. however you brought up an important point how do I configure the core clk to be 160MHZ?  is the instruction cycle based on the core clk?

Thanks,

I think I got THIS.

Thanks

Hi @hajianik,

The RTD configuration tool allows you to easily configure the clock according to the Oprion B 120MHz configuration:

RM, rev.7, Table 148. Option B - Reduced Speed mode (CORE_CLK @ 120 MHz).

Please keep in mind that all the clocks must be configured as per the table if the CORE_CLK = 120MHz.

Regards,

Daniel
