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:
config SET_NVS_SECTOR_SIZE int "sector size used by default NVS backend" default FLASH_ERASE_BLOCK_SIZE
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.
