I am working on a subsystem and I have some problem with Kconfig. I
would like to define a configuration setting: SET_NVS_SECTOR_SIZE and
apply a default equal to the define FLASH_ERASE_BLOCK_SIZE:
int "sector size used by default NVS backend"
but this doen't work: cmake complaints that FLASH_ERASE_BLOCK_SIZE is
not defined. However I can use FLASH_ERASE_BLOCK_SIZE in a .c or .h
file, and its value is set correct.
How should I do this in Kconfig ?
