The chip does not work after being powered on

Hi,

I use the chip S32K311. When I add the Clock_init function, my chip does not work after power-on, but is normal in debugging state. May I ask why?

Hello,

This looks like SW issue.

Did you configure clock properly in datasheet specified range? What if you lower clock? Still the same?

Any watchdogs are running?

Best regards,

Peter

Thank you,
I lowered the HSE_CLK rate, and the problem was solved.
