Hello Daewoong,

The easiest way is to search on our Devzone site.

There are thousands of questions that have already been registered by multiple engineers.

and If you want to check on our document page, you can check the keyword in the Kconfig menu as well.

This menu is providing some comments for each configuration item.

and the last one is trying to check the sample code.

Usually, I build some sample code first and check the source code with the ".config" which is located in the "build/zephyr". because this configuration file was generated by overlay and target board configuration.

Thanks,

Eugene

Hello Eugene

Thank you for the answer.

I have another question... you said "set the BOARD_ENABLE_DCDC in the overlay file".

Then, how did you know that?? is there any reference documentation?

Even if i've find the information related to "BOARD_ENABLE_DCDC" setting in the document page (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest), I couldn't find any information.

it might be a little weird... but, i want to learn about that.

How did you know those information...?

Thanks,

Daewoong Kim

Hi Daewoong,

You need to set the BOARD_ENABLE_DCDC in the overlay file.

This configuration is enabled by default in the nrf52840dk_nrf52840 board configuration.

Thanks,

Eugene
