Try this as the first action in main():

 // The DC/DC regulator may be used as an alternative to the LDO regulator
 // provided the inductors are installed. Enable the DC/DC through the
 // DCDCEN. Using the DC/DC regulator will typically reduce current consumption
 //compared to using the LDO regulator
 NRF_POWER->DCDCEN = 1;

I use nRF5_SDK_12.2.0_f012efa. First design of the device is about 6 years old.

Ticket you mentioned above as I see related to significantly later project with Zephyr OS. My project based on RTOS

Please advice regarding to SDK version 12.2 beta.

It is also not clear to me if NRF_POWER_HAS_VDDH shall be defined or not. My power supply is 3.3V

Best regards

Hi Michael,

Which SDK are you working on? Is it the nRF Connect SDK? Please take a look at this ticket and let me know how it goes.

Best Regards,
