Thanks!

I also found another option - to use gpio hogs

&gpio1 {

power-hold {

status = "okay";

gpio-hog;

gpios = <15 GPIO_ACTIVE_HIGH>;

output-high;

};

I'm using it on the mcuboot overlay + my application overlay since it's a multi image build.

Appreciate the help

Noy

Hi,

You can use the regulators-fixed subsys to do this. Here's an example on how the DT will look:

Remember to add this as a board overlay for mcuboot as well as setting CONFIG_REGULATOR=y

Kind regards,
