Support for pollable buttons is enabled with:
CONFIG_ARCH_BUTTONS=y
For interrupt driven buttons, add:
CONFIG_ARCH_IRQBUTTONS=y
Program interfaces for button access are described in nuttx/include/nuttx/arch.h
There is an example that can be enabled to test button interrupts. That
example is enabled like:
