S32 K118 Internal clock Lin

I use S32k118, there is no external crystal oscillator, so i use internal clock.

The problem is that the system is works fine in debug mode. And If power off, then power on, it can't run normally.

Attached is the clock config. Is there anything special when use internal clock? Could you give me some supports?

Thanks very much!

Hi Jianfeng2,

If you are using S32K1 SDK, please check if "START_FROM_FLASH" Symbols are missing? refer to the discussion: S32K188 runs with debugger, but not witout

If you suspect the clock is inaccurate, please observe the frequency of internal clock through the CLKOUT pin.

Best Regards,
Robin
