Hi David,

When trying to build your sample, could you share the problems window too? For eg, when I tried to reproduce your error, I get the following problems:

Do share yours. Also, I saw that you have a thingy53 board files and hence was building for that board.

Attached is a zip with my custom board files and the project files.

Hi David,

Is it possible to share your project zip file so that I can check it here at my end?

I understand that. I am trying to figure out where this dependency is missing from. Can you point me to where this dependency should originate from? I believe I have it enabled in the device tree, therefor I am having issue determining why the dependency is missing.

Hi David,

Missing dependencies mean that in order to get a config to actually be enabled, you will also have to enable it's dependencies. Here it means that in order to actually enable CONFIG_LED_PWM, you will need to enable it's dependencies too.

Have you enabled these dependencies?

Hi,

I've now also noticed that "CONFIG_LED_PWM=y" is underlined orange in vscode because it is missing dependency "DT_HAS_PWM_LEDS_ENABLED". I'm guessing this means I have something incorrect in my dts or dtsi file but I'm not currently sure what it could be.

Hi Priyanka,

The PWM code is based off of the rgb_led zephyr example. The board file is being built for a custom hardware, but I currently have files set up to work with an nRF52832 dev kit for basic development.

Hi David,

Did you refer any of the Nordic Samples? Is your application based on any of the samples?

Which board are you working on?

Regards,

Priyanka
