RE: Error building with Custom board

Your custom board device tree lacks proper GPIO node definitions or aliases for LEDs/buttons expected by the sample. Fix those in your .dts or overlay files to match the sample’s GPIO usage.

Hey, thank you for your answer. However, It doesnt work this way.

Hi,

Could you try deleting the build folder and rebuilding? A pristine build is required when changes are made to the devicetree or configs.
