How can I increase the number of aliases leds in NRF5340-DK via overlay file

Hi

I want to increase the number of leds in DTS file of peripheral-uart sample by using overlay file.

Is it possible to manipulate the aliases in DTS file by editing the overlay file?

Hello!

How to use devicetree overlays is detailed here:

Hi

I tried by adding the following code to overlay file:

&aliases {

               led4 = &led4;

};

By doing this the NRF connect software couldn't load NRF connect sdk project and a python error was issued.

Is there a &led4 node in your devicetree?

I believe the default leds on the nRF5340 DK would be labeled led0-3
