Hello,
I am trying to configure a visible symbol in the Kconfig.board file of my project.
This is what the Kconfig file looks like:
config BOARD_NRF52840_HUME
bool "nRF52840 HUME"
depends on SOC_NRF52840_QIAA
config HAS_VALENCELL
bool "valencell sensor present"
Where the new thing I want to add is the HAS_VALENCELL.
Then in the nrf52840_defconfig file I define it like that:
CONFIG_HAS_VALENCELL=y
The error when I try to build the code is the following:

Any help on how this can be fixed or what is causing the problem would be helpful.
