NRF Connect SDK - Change regulator LDO configuration

[thiago_hd]

How can I change the regulator configuration (specially the LDO voltage output) in runtime, and also, how could I do it in compilation time?

PS: I use mcuboot as well.

HI Thiago,

You will need to set the voltage using nrfjprog.. There is no function that writes to this section of uicr from the cpu itself.. You can take a look at this thread:  Using nRF5340-PDK at 3.3V instead of 1.8V 

Regards,

Swathy

The code actually worked. After a full erase of the chip it worked.
