Hi again

Disregard my previous comment, the spaces are not a problem.

The problem is that the binding you have specified (gpio-ctrl) is not defined. If you choose another binding, like for example gpio-leds, your code compiles.

So you will have to either find a suitable predefined binding that suits what you are trying to achieve:

Or define your own binding:

It's still wrong.Use ncs 2.1.1.

Can you try writing <&gpio0 15 0x0> instead of < &gpio0 15 0x0 > in your overlay file?

(no spaces next to the brackets)

DT_ALIAS(ctrl0) looks for a node with the alias ctrl0, but in the code you've shared you have not defined any alias.

Try using DT_NODELABEL(ctrl0) instead.
