S32K142 WDOG unlock failed

[Ada_Lovelace]

Hi，all

I want to use the wdog，but when I init it ,it stops in

"while(((WDOG->CS & WDOG_CS_ULK_MASK)) == 0);"

What should I check to solve it?

HI,

I have solved the problem, the hardware changes the Crystal oscillator, the input clock selects the SIRC,it works.

Hi Ada_Lovelace,

Maybe you can refer the codes in S32SDK example wdog_interrupt_s32k142

Best Regards,
Robin
