HardFault_Handler

[Nordic_LS]

when I call the function nrfx_power_init(nrfx_power_config_t const * p_config); the program will go to HardFault_Handler

[Igor]

What is the error code?

There are many possible reasons:
- init already done
- incorrect NRFX_POWER_*** settings in sdk_config.h or app_config.h
- incorrect  *p_config parameter passed to the nrfx_power_init() call
- etc.

Error code (and stack trace) gives you an idea, what might be wrong.

thank you for answer, I have found the reason of the problem.because I enable the clock interrupt and  the power interrupt simultaneously
